If I want to use solar charging panel , do I have to use exactly one with output 9V and 10W or some variation in Volts and Wats are possible?
Is it possible to use AA batteries (as backup) at the same time as with 220V mains power ?
As i understand it, the description says it's powered off AA batteries or mains power, so I'm wondering what the 12V battery is for? Also, is the 12V battery rechargable?
