A 36-volt solar panel can be used to charge a 12-volt battery. Can I still use it or am I better off returning the inverter? None yet. Watts are Watts! You are better off returning it or changing your SCC to 36 volts But I think having a standard voltage like 12 would be. . So I've been given a 180w 36v solar panel and I would like to use it with a singular 12v battery. There seem to be a lot of 12/24v MPPT controllers out there but I can't seem to find anything of a decent price that can handle 36v input and 12v output. DIY installations are very popular since they save up to 15% of the cost of going solar.
[pdf] To calculate the DC current draw from an inverter, use the following formula: Inverter Current = Power ÷ Voltage Where: If you're working with kilowatts (kW), convert it to watts before calculation: Inverter Current = 1000 ÷ 12 = 83. 33 Amps So, the inverter draws 83. Perfect for solar, battery, or UPS system design and performance checks. The Inverter Current Calculator calculates the input and output current required in an inverter, depending on the power, voltage, and efficiency. Over time, their usage expanded to include renewable energy systems, where they convert DC from solar panels or batteries to AC for home or grid use. So you need a wire that can handle more than 166 amps.
