Common questions
What is the Simu 9020638 charger for?
Simu's FAQ names charger 9020638 for recharging AutoSun 2 batteries. Unplug the battery from the motor, connect it to the charger, and charge for at least 3 hours. Simu says a charged battery should read about 13 volts before you reconnect it.
What power does it accept?
Simu's AutoSun 2 datasheet lists an input of 100-240V AC ±10% at 50/60 Hz for charger 9020638, with both EU and US plugs. That input range covers standard North American 120V outlets, so you can charge on site with the US plug.
How does it connect to the battery?
The charger ends in a 2-point male Molex connector, according to Simu's AutoSun 2 datasheet. AutoSun 2 motors use two 2-point connectors, while AutoSun 1 motors use one 4-point connector, so check your system generation before ordering part 9020638.
Is this the same as the Battery Charger V2 (9029465)?
They are separate Somfy references. Simu's AutoSun 2 documentation names 9020638, while Somfy Pro currently lists the Battery Charger V2 US kit as 9029465 for the T3.5 ESP Hz motors. Both charge AutoSun 2 NiMH batteries; confirm which one your installer specifies.
