For large windows, I’d start with the DIY 24V DC Tubular Roller Blind Motor Kit: its stated 1.5 N·m torque and 1.5-inch tube fit make it the clearest power-focused pick here. The Matter Smart Blinds Motor Kit stands out for smart-home compatibility, while the Rollerhouse Rechargeable Wireless Kit keeps operation simple with a remote. The main tradeoffs are motor strength, compatibility with your existing tube, power arrangements, and how much setup you’re willing to take on. A kit that fits the tube but lacks suitable torque may struggle with a wide or heavy shade, so check both before buying. Read on for how all seven options compare and which buyer each one suits.

Key Takeaways
- The 24V DC kit leads for large-shade potential: it is the only listing here with a stated 1.5 N·m torque figure, though buyers must supply a compatible 24V adapter.
- Tube diameter narrows the field quickly: four options name a 1.5-inch or 38mm tube, while the AM22 is for 1.25-inch tubes and the 28mm Rollerhouse kit needs a smaller tube.
- Smart control adds setup choices: Matter offers broad named platform compatibility, while the AM25 is a bare motor that needs an AC520 hub for app or voice control.
- Simple remote operation has a clear tradeoff: the Rollerhouse rechargeable kit pairs a motor and remote, but it does not advertise the smart integrations listed for Matter or AM22.
- Power and convenience pull in different directions: solar charging suits a bright window, a rechargeable motor avoids a fixed power adapter, and the 24V kit prioritizes a wired power arrangement.

Rollerhouse 28mm (1-1/8 Inches) Round Tube Battery Roller Shade Motor Kit with Remote Control for Electric Window Blinds
For a large window with an existing 28mm round tube, this kit offers a straightforward battery-powered retrofit without requiring a nearby outlet. Its 6.6 lb lift limit is the main constraint: it suits lighter roller shades, but heavier or especially wide fabric may call for the higher-capacity Rollerhouse 1.5-inch kit, rated for 8.8 lb. The included remote and 8.4V charger make this a more complete starting package than the AM25 bare motor, though you still need to source the mounting bracket or adapter separately. Tube measurements matter here, and the kit excludes pleated, aluminum, and vertical blinds. I’d shortlist it when the existing tube matches and the shade is comfortably within its load limit; it is a poor fit for oversized, heavy panels.
Pros:- Rechargeable battery operation avoids running a power cord to the window.
- Includes a remote and 8.4V charging adapter.
- Supports compatible sheer horizontal dual-combi, Zebra, Roman, and mini blinds.
- Solar charging is supported for buyers who want a wire-free charging setup.
Cons:- The 6.6 lb capacity is lower than the 8.8 lb Rollerhouse 1.5-inch kit and may rule out heavy large-window shades.
- Requires a compatible 28mm tube and a separately sourced mounting bracket or adapter.
- Not compatible with pleated, aluminum, or vertical blinds.
Best for: Homeowners retrofitting a light-to-moderate roller shade on a 28mm round tube who want remote control and rechargeable power.
Not ideal for: Buyers with heavy or extra-wide shades, a different tube diameter, or pleated, aluminum, or vertical blinds; the lift limit is 6.6 lb and the mounting adapter is not included.
- Tube diameter:28mm (1-1/8 inches)
- Maximum shade load:6.6 lb
- Power:Rechargeable battery
- Included charger:8.4V charging adapter
- Control:Remote control
- Compatible shade types:Sheer horizontal dual-combi, Zebra, Roman, and mini blinds
- Mounting adapter:Not included
Our verdict“Choose this for a light shade on a matching 28mm tube, but look to the higher-capacity Rollerhouse kit for heavier fabric.”
AM25 RF Solar Powered Rechargeable Blinds Motor, Bare Motor Only for 1.5″ (38mm) Tubes, DIY Manual to Motorized Roller Shade Conversion Kit Compatible with AC520 Hub for App & Voice Control
The AM25 makes the most sense for a large patio or RV shade where solar-compatible charging and a water-resistant design matter more than an all-in-one kit. Its built-in lithium-ion battery can charge over USB-C or pair with a solar panel, keeping wiring away from the window. Compared with the Rollerhouse 1.5-inch kit, this motor is better suited to damp outdoor settings, but it gives you less in the box: it is sold as a bare motor, and the charger and smart-home hub are separate purchases. It fits only 38mm tubes, so measuring the existing roller is a must. The optional AC520 hub adds app and voice control; without it, this is a more basic RF-controlled setup. I’d skip it for buyers seeking a ready-to-install indoor package.
Pros:- Built-in rechargeable battery supports USB-C charging and optional solar charging.
- Water-resistant design suits patio and RV installations better than the non-water-resistant Rollerhouse kits.
- Tool-free DIY installation is described for compatible 38mm tubes.
- Optional AC520 hub adds app, scheduling, and voice-assistant control.
Cons:- Bare-motor format means the charger and AC520 hub are separate purchases; package details also vary on whether a remote is included.
- Smart-home control depends on the separately purchased AC520 hub.
- Limited to 1.5-inch (38mm) roller shade tubes.
Best for: DIY owners of 38mm roller shades on patios, RVs, or other locations where water resistance and solar-assisted charging are useful.
Not ideal for: Buyers who want a complete indoor kit in one box, need a motor for a non-38mm tube, or expect app and voice control without buying the AC520 hub.
- Tube diameter:1.5 inches (38mm)
- Power:Built-in lithium-ion battery
- Charging:USB-C or optional solar panel
- Control:RF remote control; AC520 hub required for app and voice control
- Mounting:Inside or outside mount
- Water resistance:Water resistant
- Dimensions:17.24 x 1 inches
Our verdict“Pick the AM25 for a compatible outdoor shade where solar-ready power matters, not for a complete plug-and-play indoor retrofit.”
Rollerhouse Rechargeable Wireless Tubular Roller Shade Motor Kit with Remote Control – 1.5-inch Tube
Among these battery kits, this Rollerhouse option is a useful middle ground for large windows: its 8.8 lb capacity exceeds the 28mm Rollerhouse kit’s 6.6 lb limit, while the included remote and charger make it more ready to install than the AM25 bare motor. It works with a 1.5-inch tube and supports inside or outside mounting, giving DIY buyers flexibility when replacing a chain drive. That load rating still calls for care with very wide, heavy fabric; the Matter kit lists support for about 11 lb, and the EY2524 reaches 12 lb. The tradeoff is that the mounting adapter is sold separately, and this motor is not water-resistant. It also excludes pleated, aluminum, and vertical blinds, so it is for compatible roller-style shades rather than every window treatment.
Pros:- Supports shades up to 8.8 lb, more than the 6.6 lb 28mm Rollerhouse kit.
- Rechargeable battery, remote, and charger are included.
- Supports both inside and outside mounting.
- Designed for DIY retrofits to compatible roller, Roman, and mini blinds.
Cons:- Mounting bracket or adapter is sold separately.
- Not water-resistant, limiting use in humid or exposed locations.
- Its 8.8 lb capacity falls below the Matter kit and EY2524 ratings.
Best for: DIY homeowners with a compatible 1.5-inch roller shade who want a rechargeable retrofit with remote and charger included and a higher load limit than the 28mm kit.
Not ideal for: Owners of very heavy large-window shades, damp locations, or pleated, aluminum, and vertical blinds; its 8.8 lb capacity and shade-type limits may not fit.
- Tube diameter:1.5 inches
- Maximum shade load:8.8 lb
- Power:Rechargeable battery
- Included components:Motor, remote control, and 8.4V charger
- Mounting:Inside or outside mount
- Water resistance:Not water-resistant
- Material:Metal and plastic
Our verdict“Choose this as a practical rechargeable retrofit for a compatible medium-to-heavy shade, but step up to a higher-capacity motor for heavier window coverings.”
DIY 24V DC Tubular Roller Blind Motor Kit (EY2524) – 1.5 N·m Smart Shade Motor with Remote Control for 1-1/2″ (38mm) Tubes, Requires External 24V Adapter
For a large window with a heavier shade, the EY2524 has the strongest stated load capacity here: up to 12 lb, ahead of the Matter kit’s approximate 11 lb and the Rollerhouse 1.5-inch kit’s 8.8 lb. Its 1.5 N·m torque and 24V motor make it the more compelling choice when a battery model’s load ceiling is too low. The package includes a remote and mounting brackets, which gives DIY installers more hardware than the AM25 bare motor. The tradeoff is power: this model needs a separate external 24V adapter, so it is less convenient where a window has no nearby outlet. It also fits only 38mm extruded aluminum tubes, not round tubes or other diameters. Smart-home use requires an RF/Wi-Fi gateway, adding another component.
Pros:- Highest stated capacity in this group at up to 12 lb.
- 1.5 N·m torque is suited to heavier roller shades.
- Includes a remote, shade bracket, rubber fittings, and installation instructions.
- Can support Google Assistant and Alexa through an RF/Wi-Fi gateway.
Cons:- External 24V DC adapter is required and sold separately.
- Smart-home control requires an additional RF/Wi-Fi gateway.
- Fits only 38mm extruded aluminum tubes.
Best for: Buyers motorizing a heavy, compatible 38mm extruded-aluminum roller shade who can provide a nearby 24V power source.
Not ideal for: Renters or homeowners seeking a cordless retrofit, owners without access to a 24V adapter, and anyone with a round or non-38mm tube.
- Motor model:EY2524
- Voltage:DC 24V
- Torque:1.5 N·m
- Maximum shade load:12 lb
- Tube compatibility:38mm (1-1/2-inch) extruded aluminum tubes
- Power supply:External 24V DC adapter, sold separately
- Included components:Motor, remote, shade bracket, rubber fittings, and instructions
Our verdict“Choose the EY2524 when lifting capacity is the priority and a wired 24V power supply is practical.”
Matter Smart Blinds Motor Kit for 1.5″ Shade Tube – Type-C Rechargeable Roller Shade Motor, Thread, Home Assistant, Alexa & HomeKit Compatibility
This kit stands out for buyers who want a large roller shade tied into a Matter Thread smart home without running power wiring. It supports Apple Home, Google Home, Alexa, and Home Assistant, while the included RF433 remote offers local control at a stated range of up to 300 feet. Its approximate 11 lb capacity puts it above the Rollerhouse 1.5-inch kit but just below the wired EY2524, so it balances broad control options with a respectable load limit. USB-C charging and a stated 3–5 months per charge keep routine power needs manageable, though heavier shades may need more frequent charging. The kit includes a bracket, unlike the AM25 bare motor, but its single-channel remote is less suited to controlling several window zones from one handset.
Pros:- Matter Thread compatibility spans Apple Home, Google Home, Alexa, and Home Assistant.
- USB-C rechargeable battery avoids the external wiring required by the EY2524.
- Approximate 11 lb capacity is higher than the Rollerhouse 1.5-inch kit.
- Includes a one-channel remote, charger cable, and roller blind bracket.
Cons:- Heavier shades can shorten the stated 3–5 month battery life.
- Only a single-channel remote is included, limiting out-of-box multi-zone control.
- Compatible only with 1.5-inch shade tubes.
Best for: Smart-home owners with compatible 1.5-inch roller shades who want Matter Thread integration, rechargeable power, and remote operation.
Not ideal for: Buyers with tube sizes other than 1.5 inches, very heavy shades above about 11 lb, or several blind zones they want to control separately with the included remote.
- Tube diameter:1.5 inches
- Maximum supported weight:Approximately 11 lb
- Smart-home protocols:Matter Thread
- Compatible platforms:Apple Home, Google Home, Alexa, and Home Assistant
- Remote range:Up to 300 ft (RF433)
- Charging:USB-C
- Battery life per charge:3–5 months, depending on load
- Included items:Motor, one-channel remote, USB-C charger cable, and roller blinds bracket
Our verdict“Choose this for a compatible large shade when smart-home integration and cordless charging matter more than the EY2524’s extra lifting capacity.”
AM22 Smart Tuya Zigbee Blinds Motor Kit, Rechargeable Roller Shade Motor for 1.25″ (32mm) Tubes, App/Voice Control, Works with Alexa & Google Home, DIY Manual to Motorized Blind Conversion Kit
For a large window with an existing 1.25-inch tube, the AM22 offers a cordless way to motorize a manual roller, zebra, or sheer shade. Its built-in rechargeable battery avoids a dangling power cord, while app schedules and group control can make several compatible shades easier to manage. Compared with the Progressive Automations PW-RS1, it has a more specific tube fit and does not list a maximum shade weight, so I would not choose it for a heavy, wide covering without confirming capacity first. It also needs a Tuya Zigbee hub for smart features, adding setup and hardware beyond the motor itself. The 32mm fit and lack of continuous plug-in power are the main limits for buyers outfitting large windows.
Pros:- Built-in rechargeable battery avoids running a power cord to the shade.
- DIY installation requires no wiring or professional tools.
- Zigbee supports app scheduling, group control, and Alexa or Google Assistant voice commands through a Tuya hub.
- Designed for compatible roller blinds, zebra blinds, and sheer shades.
Cons:- Smart control requires a separate Tuya Zigbee hub.
- Fits only 1.25-inch (32mm) aluminum tubes.
- No continuous plug-in power option, and no maximum shade weight is listed.
Best for: DIY owners with manual roller, zebra, or sheer shades on 32mm tubes who want rechargeable power and already use, or plan to add, a Tuya Zigbee hub.
Not ideal for: Buyers with wider or heavier shades who need a stated weight capacity, owners of tubes other than 32mm, or anyone who wants plug-in power instead of periodic recharging.
- Compatible tube size:1.25 inches (32mm) aluminum roller shade tubes
- Power:Built-in rechargeable lithium-ion battery
- Charging:USB-C
- Connectivity:Zigbee through a Tuya hub
- Voice control:Alexa and Google Assistant
- Installation:DIY; no wiring or professional tools required
- Package dimensions:17.44 x 3.39 x 2.76 inches
- Item weight:1.65 pounds
Our verdict“Choose the AM22 for a compatible 32mm shade and hub-based DIY control, but look elsewhere if your large window covering is heavy or needs a published load limit.”
Progressive Automations Electric Roller Shade Motor Retrofit Kit
The PW-RS1 is the more compelling choice here for a large, weightier roller shade because it lists a 20-pound maximum shade weight, a useful selection point missing from the AM22. Its included brackets, adapters, remote, and solar panel make this a fuller retrofit package, while Matter compatibility covers Alexa, Google Home, Apple HomeKit, and SmartThings. A listed noise level of 32 dBA or less suits rooms where motor sound matters, and the 100-foot remote range gives more flexibility across a large room. The tradeoff is that this remains a retrofit for an existing indoor roller shade, not a complete window covering. Compared with the AM22, its broader smart-home support and stated load limit suit more demanding installations, but the shade still needs to match the kit’s fit requirements.
Pros:- Rated for shades up to 20 pounds, giving large-window buyers a clear weight limit.
- Matter compatibility supports Alexa, Google Home, Apple HomeKit, and SmartThings.
- Quiet operation is listed at 32 dBA or less, with adjustable speed settings.
- Included solar panel can extend battery life between charges.
Cons:- Requires an existing manual roller shade and does not include the shade itself.
- Limited to indoor use.
- Battery life is listed as 4–6 months, so it is not a maintenance-free power setup.
Best for: Homeowners motorizing an existing indoor roller shade on a large window who need a stated 20-pound capacity, quiet operation, and compatibility across major smart-home platforms.
Not ideal for: Buyers who need a complete shade rather than a retrofit kit, outdoor use, or a motor system for coverings heavier than 20 pounds.
- Maximum shade weight:20 pounds
- Noise level:≤32 dBA
- Battery:2500mAh lithium-ion
- Listed battery life:4–6 months
- Smart-home compatibility:Matter; Alexa, Google Home, Apple HomeKit, and SmartThings
- Remote range:100 feet
- Dimensions:22 inches long x 0.94 inches wide
- Included components:Motor, brackets, solar panel, remote, adapters, and end plug
Our verdict“Pick the PW-RS1 for a heavier indoor roller shade and broad smart-home support, provided the shade weighs no more than 20 pounds.”
How We Picked
I ranked these kits around the challenges large windows create: moving a potentially heavier shade, fitting the motor to an existing tube, and choosing a power source that works for the window. I gave more weight to listings with specific fit or performance details, such as the 24V kit’s stated 1.5 N·m torque and named tube size, than to options whose listing leaves those details open. I also compared whether a kit includes a remote, uses rechargeable or solar power, or adds smart-home control.
The order reflects how directly each kit appears to address a large-window installation, balanced against setup demands and compatibility limits—not price or claimed real-world performance. A motor’s stated tube fit does not establish that it can lift every shade of that size, so I treat missing torque, shade-weight, and adapter details as reasons to verify before purchase. Kits with narrower tube requirements or extra hub and power needs rank lower for broad use, but may still suit a buyer whose setup matches.

Factors to Consider When Choosing Motorized Blinds Kits For Large Windows
For a large window, start with the shade and installation rather than the app features. I’d confirm the mechanical fit and likely load first, then decide which power source and controls make day-to-day use easiest. These checks can prevent a kit that looks suitable on paper from becoming an awkward retrofit.
Match Motor Capacity to the Shade, Not Just the Window
A wide window often means a larger, heavier shade, but window width alone does not tell you what a motor can lift. Shade material, drop length, tube diameter, and the shade’s total weight all affect the load. Look for a stated torque or supported shade-weight range, then compare it with the seller’s fit guidance for your shade. A torque figure such as 1.5 N·m gives you more to evaluate than a listing that names no capacity, but it still does not guarantee a match. If the listing omits capacity guidance, ask the manufacturer before buying rather than assuming that a compatible tube means adequate lifting power.
Measure the Tube and Check the Internal Shape
Measure the tube’s outside diameter at the point where the motor will sit, and check the tube profile as well as the size. The products in this roundup span 28mm, 32mm, and 38mm or 1.5-inch fit claims, so choosing by product name alone can lead to a motor that will not seat correctly. Check whether the kit includes adapters, and whether your tube has a compatible internal shape and usable space. Also confirm that the shade can be removed and reinstalled without damaging its brackets or fabric. When replacing an existing mechanism, compare the full kit’s dimensions with your current hardware before ordering.
Choose Power Around Window Access
Power choice affects both installation and upkeep, especially when a large window is difficult to reach. A rechargeable motor avoids a permanent wire run, but you need a practical way to charge it when its battery runs low. A solar panel can reduce routine charging when the window receives suitable light, though placement and exposure matter. A 24V system calls for a compatible adapter and a plan for routing power neatly. Before choosing, check whether the power source is included, where it connects, and how you will reach it for service.
Decide How Much Smart-Home Setup You Want
Remote control is usually the more direct path if you mainly want to raise and lower a shade without using a phone. App and voice control can be useful for schedules or shared routines, but those features may depend on a hub, protocol, or compatible home platform. Read the exact compatibility notes: the Matter kit names several platforms, while the AM25 listing specifies an AC520 hub for app and voice control. Do not assume that “smart” means the motor connects directly to your Wi-Fi or works with every assistant. If reliability matters more than automation, a simpler control setup may be easier to maintain.
Account for the Whole Installation
A motor kit is only one part of a large-window retrofit: brackets, tube adapters, a power adapter, a charging cable, a remote, or a hub may affect the complete setup. Check what is included instead of assuming that every named accessory comes in the box. Large shades can also need careful alignment so the fabric rolls evenly and does not rub against the frame. Make room for any motor head or cable near the bracket, and check that the window trim will not block installation. If you need to alter the shade or fabricate parts, the apparent convenience of a DIY kit may not outweigh the extra work.
Frequently Asked Questions
How do I know whether a motor kit can lift my large shade?
Start with the shade’s weight and dimensions, then compare them with the motor’s stated torque or supported-load guidance. Tube compatibility alone does not show that a motor can handle a heavy shade. In this lineup, the 24V DIY kit lists 1.5 N·m torque, while several other product names do not provide a comparable capacity figure. Ask the seller or manufacturer for a suitability check if your shade is wide, long, or made from a heavy material. Avoid relying on window width as a substitute for load information.
Can I use a 1.5-inch motor in a tube listed as 38mm?
The listings use both measurements, and 1.5 inches is close to 38mm, but that does not prove every motor and tube will fit together. Check the manufacturer’s adapter and tube guidance, including the tube’s internal shape and the space available for the motor. A tube may also be slightly different from its nominal size. Compare your measurement with the product’s fit details before ordering. If the seller does not confirm compatibility, do not assume the two labels guarantee a match.
Is a solar-powered motor a good choice for a large window?
It can be a good fit when the panel can receive enough light and can be mounted where it will stay accessible. Solar charging may reduce manual charging, but it does not remove the need to check the motor’s lifting capacity against the shade. The AM25 listing also describes a bare motor, so app or voice operation requires an AC520 hub. Check what components are included and how the panel connects before choosing it. For a shaded window or a heavy shade, compare other power options and ask for load guidance.
Should I choose a remote kit or a smart kit for a room with several large shades?
Choose based on how you plan to operate the shades and how much setup you want to manage. A remote-focused kit, such as the Rollerhouse rechargeable option, keeps controls straightforward, while Matter or Tuya Zigbee options offer app and voice features named in their listings. For several windows, check whether one control can operate multiple motors and whether each motor needs separate pairing or a hub. Confirm compatibility with your existing smart-home equipment rather than relying on a general platform label. If simple, dependable daily operation is your priority, a remote may be a better match than added automation.
What should I check before converting an existing manual blind?
Measure the tube diameter and inspect its profile, brackets, and available clearance before choosing a retrofit motor. Confirm that the shade can be removed and reinstalled, and check whether the kit includes the adapters needed for your tube. Then compare the shade’s weight and dimensions with the motor’s capacity guidance. Finally, plan where the remote, charging access, adapter, solar panel, or hub will go. Taking these measurements before purchase helps avoid a kit that fits one part of the setup but not the rest.
Conclusion
For a broad large-window starting point, I’d choose the DIY 24V DC Tubular Roller Blind Motor Kit as best overall because it gives a stated torque figure and a 1.5-inch tube fit; its external adapter requirement is the main tradeoff. The AM22 is my best value in features for buyers with a compatible 1.25-inch tube who want app and voice control, while the Progressive Automations Electric Roller Shade Motor Retrofit Kit is my premium pick for shoppers focused on a dedicated retrofit option and willing to verify its specifications before purchase. For beginners who want a simpler control setup, I’d pick the Rollerhouse Rechargeable Wireless Kit with its remote, provided the tube and shade load are a match. For a bright window and a compatible 38mm tube, the AM25 solar motor suits buyers comfortable adding its required hub for app or voice control. If smart-home platform compatibility matters most, choose the Matter kit; if your existing tube is 28mm, the Rollerhouse 28mm kit is the specifically sized option. In every case, verify motor capacity and complete kit contents before committing to a large-shade installation.
