Solar panel 50 watts to charge controller and 12 Volt Battery?
I want to charge up to a 12 volt battery. How long can I use a heater and refrigerator?
You didn't mention the inverter to provide mains 230AC from the battery. The Solar panel will not give 50 watts all day - at this time of year less then half. So assuming its summer, its bright sunshine, your panel will give 50 watts for 8 hours maybe. This means the battery can only give back 50 watts for 8 hours, less the losses from the mains inverter and charge controllers, which are not 100% efficient. So the setup just might run the fridge for about 2 hours and the heater for half an hour, assuming its a 1kw heater and that the inverter will cope with load.
