20kw  solar system load reference:

Remark: Refrigerator,air conditioner &water pump is inductive load ,start working power is 3-6 times more than normal power ,in the process of use ,turn on the inductive load first

How does the off grid solar power system work:

This system not only has solar power system function,but also has city grid complement function and UPS function
At daytime,the solar panels will generate the electricity to charge the battery bank through solar charge controller and the inverter will convert battery DC power into AC power and take the loads.
At nighttime,with fully charged battery bank,the inverter will convert battery DC power into AC power and take the loads
When there is no sunshine and battery power is used out,the inverter will automatically switch to use city grid power and take the loads
