hey so i just started the idea of biulding a tiny home which is a 12 foot trailer after grabbing a watt tester and testing my top watts used per hour not including my back up electric fireplace is around 250-350watts this is what ive been looking at but might change my mind depending on your guys help
products im looking to use
batterys :
Power Safe SBS170F 12 Volt Solar battery's ?(100$ each used company went under cuz of covid)
solar panels : are 300 watt hhv solar tech panels x2 (125$ each used )
charge controller : Renogy Rover 40 Amp 12V/24V DC Input MPPT Solar Charge Controller(brand new 200$)
and a inverter of course now that added up is 741 amp hours of battery on 600watts of panels but from what i was reading i NEED a mppt charge controller on any solar panel over 100watts or useing a pwm on a 300watt panel will basically make it run as a 100watt panel (yes my system will be 12 volts)
or other idea would be to run
the same batterys 4-6 100watt panels to stay with the 12volt panels and a pwm controller. useing a pwm controller is much cheaper but still seem to work fine for 100 watt panels batterys will still cost me the same and 100watt panels well there all over and seem work work around the same ish 70-85watts per panel
so what do you guys think it the better way to go about this? they both will end up costing me about the same either way
