I have a 175 watt panel system in shed to learn and charge power tool batteries. It doesn’t work below freezing so looking to do system two in house. I want to start with 400 watts of panel but they will be 25 ft from mppt controller then 200amp lithium batteries and inverter than 10 more feet to power panel . Now the questions what wire sizes?
12 or 24 volt panels? What size inverter? There is room for 800 watts of panels , how much bigger wires would it take?
