FAQ of Off-Grid Solar Energy Storage System

Q1: What is the difference between different power models?

A: The core difference lies in maximum AC output power, solar panel quantity and battery capacity. Small power 5/10KW is for household daily light load; high power 30/40KW supports large inductive loads such as water pumps and air conditioners for full-load continuous power supply.

Q2: Can this system work without solar light for several consecutive rainy days?

A: The matched LiFePO4 battery pack stores enough electricity to support several days of basic load power supply under continuous cloudy and rainy weather; sufficient sunlight during the day can fully replenish battery power.

Q3: Is professional electrician required for installation?

A: The product comes with complete English installation wiring diagram, but the system involves high DC voltage and 220V AC circuit, it is recommended to be installed by professional photovoltaic electricians to avoid safety hazards.

Q4: Can the system be expanded later to increase power?

A: Yes, the MPPT inverter supports parallel expansion, solar panels and battery packs can be added according to later load growth demand to upgrade system power capacity.
