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
Advantage:
100%green energy，no pollution，no noise
High efficiency solar panel with 25 years lifespan can guarantee fast cost-recovery and long-term benefit
Stand-alone system,easy installation and operation
Nice after-sale service,provide installation guide and technical support
Packing details:
Solar panels are packed in carton and pallet
PV combiners and inverter are packed in wooden box
Solar charge controller,gel battery,and cables are packed in carton
Solar panel racks are in cartons and bulk packing
