Somfy Irismo 45 WireFree RTS Battery Drapery Motor Guide

A retrofit drapery job stalls the moment someone asks where the power comes from. The Somfy Irismo 45 WireFree RTS Drapery Track Motor (1002353) removes that question. It runs on a rechargeable battery pack, mounts on either end of the track, and pulls draperies up to 99 lb (45 kg) with no wiring, no electrician, no conduit, and no wall damage. For a finished room where fishing a cable would mean opening drywall, the Irismo 45 turns a hard install into a bracket-and-charge job.

Drapery types the Irismo 45 moves

The Irismo 45 motorizes pinch pleat, RippleFold, and Accordia draperies on a Somfy Glydea-style track. It handles side opening and center opening layouts, and the motor conceals above the track or tucks to the left or right return. A gentle pull on the fabric starts the drape moving through Touch Motion, so a homeowner operates it by hand or by remote. Soft start and soft stop ease the fabric into each end of travel, which keeps a heavy pinch pleat from swinging when it lands. Manual override lets anyone draw the drape by hand if the battery runs down.

Weight is the number that decides the fit. A wide center-open drapery in a lined fabric can approach the 45 kg ceiling fast, so measure the finished panel weight before you commit. The Irismo 45 covers residential windows and light commercial openings where the run stays inside the track's rated length and the fabric sits under 99 lb.

Battery power without a single wire

The Irismo 45 ships with a rechargeable lithium-ion pack, and the motor accepts Somfy's 24V DC low-voltage supply. The pack lifts off to charge and drops back in, so the drape stays usable on override in the meantime. The dedicated Somfy Irismo 45 RTS Motor Battery Charger (1003080) refills the pack, and a spare pack keeps a room running while the first one charges. For a second pack or a replacement down the road, the Somfy Replacement 25.9V Li-ion Battery for Irismo 45 (9026476) is the genuine cell pack for this motor. Buy the charger with the motor on a new install, because the pack arrives ready to program but needs a top-up before long-term service.

Verified specifications

Every figure here matches Somfy's published technical data for part 1002353. The four-step speed setting is worth noting on a quiet bedroom install, since the slowest setting runs at 39 dBA while the fastest reaches 45 dBA. Pick the speed for the room, not the demo.

Track, carriers, and arm kits

The motor drives a belt inside a Somfy track, and the carriers set how the fabric stacks. For an even, architectural stack, the Somfy RippleFold 120% Carriers, 7 per ft (1780901) space the fabric into deep, uniform folds. Carrier count per foot sets the fullness, so a 120% layout reads richer than an 80% run on the same window. Mount the track with a bracket rated for the fabric weight. The Somfy Glydea One Touch Ceiling Bracket (1780907) clips the track to the ceiling without a screw through the face, which keeps the reveal clean on a recessed pocket. Confirm the master carrier and the arm kit match the opening direction before you cut the track.

Mounting the motor and planning the return

The Irismo 45 mounts on either end of the track, and that choice sets where the motor tucks out of sight. Above a deep return, the motor hides behind a fascia or a valance. On a tight reveal, plan the return depth so the motor body clears the wall and the drape still stacks clean. The One Touch bracket clips the track without a face screw, which keeps the ceiling line unbroken across a wide window. Center-open and one-way layouts each need the matching arm kit and master carrier, so confirm the opening direction on the order. A drape that stacks left on a right-hand return fights the layout every time it closes, and the fix is a five-minute planning check, not a re-order.

Control and the TaHoma path

The Irismo 45 carries an RTS receiver, so it pairs with any Somfy RTS remote or wall switch out of the box. A Situo hand remote programs the motor and sets the open and closed limits in a few button presses. Add a TaHoma smart hub and the same drape joins app control, voice assistants, schedules, and sun scenes alongside the rest of a Somfy RTS system. That upgrade path means a homeowner starts with a simple remote and grows into full automation without swapping the motor.

The Somfy Irismo 45 WireFree RTS Drapery Track Motor (1002353) is the wire-free answer for motorized drapes in a finished room, and the charger and spare pack keep it running for years.

Frequently asked questions

How much drapery weight can the Irismo 45 pull?

The Irismo 45 WireFree RTS moves draperies up to 99 lb, which is 45 kg, in side or center opening layouts. Measure the finished panel weight, including lining, before you commit, since a wide lined center-open drape climbs toward that ceiling quickly. Fabric under 99 lb on a track within its rated length is the target.

Does the Irismo 45 need any wiring?

No. The Irismo 45 runs on a rechargeable lithium-ion battery pack, so it installs with no cable and no electrician. You mount the motor on either end of the track, program it with an RTS remote, and recharge the pack on the dedicated charger when it drops. Manual override draws the drape by hand any time.

What draperies and fullness does it support?

The motor handles pinch pleat, RippleFold, and Accordia headings. Carrier sets control the fullness: RippleFold 80% at 5 carriers per foot gives a lighter stack, while 120% at 7 carriers per foot reads deeper and richer. Match the carrier count to the look and the fabric before cutting the track to length.

Can the Irismo 45 work with a phone app?

Yes, through TaHoma. The motor ships with an RTS receiver for remote and wall-switch control, and adding a Somfy TaHoma hub brings app control, voice assistants, schedules, and sun scenes. A homeowner can start with a Situo remote and add TaHoma later without replacing the Irismo 45 motor.
