Running a 120V line to an exterior solar screen costs money and site time. Somfy answers that with the Simu T3.5 ESP Hz AutoSun kit, part 2009607, which ships the motor, a 2.2 Ah NiMH battery and a solar panel under one part number. The motor turns 6 Nm at 18 rpm. Shops reach for it on retrofit screens and interior shades where no power reaches the head.
Tube fit decides this spec before anything else. The motor body measures 1.42 in across, and Somfy sets the minimum tube inner diameter at 1.57 in. A 40 mm round tube with the matching T3.5 crown and drive carries it.
The kit in one box
Somfy builds the AutoSun program around a motor, a battery in an aluminum case, a panel that recharges that battery, and the brackets that hold the panel on a fascia or a wall. Part 2009607 bundles the first three. The ref code reads T3.5DC ESP HZ 06/18 +KITSOL SP, and the KITSOL block in that string marks the kit rather than the bare motor.
Ordering the kit saves a purchasing step on a job with one or two openings. Dealers running a fleet of screens tend to buy the bare 2009597 motor and stock panels and batteries by the case. Somfy backs both paths with the same five year warranty.
Screens and shades this motor drives
Somfy lists ref 2009607 for exterior solar screens and for interior window coverings. 6 Nm at 18 rpm moves a mid size screen at a pace people accept on a facade, and 18 rpm on a 40 mm tube keeps the fabric under control on the last few inches of travel.
The 54 turn electronic limit sets the ceiling on drop. Count the wraps your fabric needs on a 40 mm tube, then stay inside 54. A 1.5 in tube picks up little fabric per wrap, so a tall screen consumes turns fast. Measure before you order.

Tube, crown and drive
Somfy publishes a 1.57 in minimum inner diameter for this ref, and the motor body sits at 1.42 in. The clearance between those two numbers is what the crown and drive fill. Somfy's own accessory list for 2009607 names the T3.5 38mm round tube, 40x1 (9001495), which gives you a tube already matched to the T3.5 crown and drive set.
Order the crown and the drive as a pair. A crown that seats on a 40 x 1 mm round tube will not hold a 40 x 0.8 mm octagonal tube, and Somfy publishes a separate octagonal drive for that profile. Fabric weight rides on the drive, so the fit there matters more than the fit at the idler.
Battery, panel and charging
The kit carries a 2.2 Ah NiMH pack in an aluminum case with a 0.6 m cable. The motor pulls 2.2 A under load and 26 W in operation, and it falls to 0 W at rest, which leaves the panel most of the day to replace what a handful of cycles took out. Somfy sells the same pack on its own as the 2.2 Ah NiMH AutoSun battery, 0.6 m cable (9020635) for service calls.
Winter sun on a north facing screen will not keep a pack full through a run of cloudy weeks. The Simu Battery Charger V2, NiMH US kit (9029465) tops a pack up from a wall outlet in those months. Keep one on the truck. A charged spare pack turns a dead screen into a two minute swap.
Radio pairing, mounting and limits
The motor carries a Simu Hz receiver at 433.42 MHz with 492 ft of open field range. That figure describes clear line of sight, and a stucco wall or a metal fascia will cut it hard. Mount the transmitter where it can see the head of the shade on a first pairing, then test from the position the client will use.
Pair the motor with a Simu Hz transmitter, and confirm the handset against the receiver marking on the motor you receive. Somfy prints the radio protocol on the motor label. Match the protocol first, then the channel count you need for the opening.
The round head on this ref takes a round head bracket or an adaptor plate. Somfy lists the R8 motor plate (9012258) for the T3.5 range, and that plate gives you a flat face to screw into a headbox when the pocket has no room for a pin mount.
Set the limits with the Hz transmitter after the motor sits in the tube and the fabric hangs free. The electronic limit holds +/-5 on repeatability across 54 turns, so the bottom bar lands where you set it cycle after cycle. Check the motor cable before you close the pocket. The 3.28 ft lead ends in a Molex connector, and that connector has to reach the battery case in its final mounted position.
Order the Somfy Simu T3.5 ESP Hz 6Nm 18rpm 12V DC AutoSun Solar Motor Kit (2009607) when the opening has no power and the fabric needs 6 Nm. Add the tube, crown and drive from the T3.5 set, then add a spare battery for the second year of service. The charger earns its place on jobs that face north.
Frequently asked questions
Does the AutoSun kit include the solar panel?
Yes. Somfy ships part 2009607 as a kit with the T3.5 ESP Hz motor, a 2.2 Ah NiMH battery in an aluminum case, and the solar panel that recharges it. The bare motor carries a different ref, so the kit number is the one to order when you want all three in a single line on the purchase order.
What tube does the Simu T3.5 AutoSun motor fit?
Somfy sets the minimum tube inner diameter at 1.57 in for ref 2009607, with a 1.42 in motor body. A 40 mm round tube such as the 9001495 T3.5 38mm round works with the matching T3.5 crown and drive. Somfy also publishes a 40 mm octagonal tube and drive for that profile.
How far does the Simu Hz radio reach?
Somfy publishes 492 ft of open field range at 433.42 MHz. Walls, metal fascias and glass coatings all reduce that figure, so test the transmitter from the spot the client will use before you close up the pocket. Repeaters and a closer transmitter position both help on long runs.
Can the battery be replaced?
Yes. Somfy sells the 2.2 Ah NiMH AutoSun battery in an aluminum case with a 0.6 m cable as ref 9020635, and the Battery Charger V2 NiMH US kit as ref 9029465. Keeping a charged spare pack on the truck turns a service call on a dead screen into a quick swap at the headbox.
