12 V · 200ah battery 2000 W inverter to use how many watts of photovoltaic panels to use 6 degrees of electricity
There are few batteries. The photovoltaic panel with 2000W load also needs 2300W. Four batteries with 12V · 200ah can meet the requirements
I would like to ask. 12 V 200ah battery 2000 Watts inverter can use how much electricity
12V * 200ah = 2400 watt hour, that is 2.4 kwh, but 70% of the battery power is almost used, so the actual power is about 1.7 kwh
