hi,
I have need of a solar generator,I am giving my self a headache with this simple project,I have studied all the wiring...easy enough,but how many watts for the solar panel,what size inverter,battery?
I need this to charge up two laptops in the evenings( one 13 mac book air+one hp 17inch),plus 2 smart phones (galaxy s3's) and use a small hand held cd player.
occasionally I will turn on the petrol generator usually at night and would like to boost up the battery if it needs it.
The unit will be stationary on a varandah,I dont want to unplug anything when boosting with the AC POWER supply,just plug the solar gen into the mains (the generator powers the house,when its on) and charge without disconnecting the panels.
I would also like some indication how much charge is in the battery.
