2.1 Household PV off-grid Power Generation System Introduction
Household PV off-grid power generation system consists of PV array
、
solar
mounting structure
、
storage battery
、
Grid
（
Diesel Generator
）、
PV off-grid inverter
with controller and conventional household loads. Use PV solar panel transform solar
energy into electrical energy, meanwhile use solar controller store electrical energy
into battery, inverter can transform battery’s DC power into 115V AC power and
230V AC power to drive household loads work.
This system can meet the demands of electric power in the areas that without
grid electricity or lack of electricity.
Meanwhile, in the area of having Grid power and Diesel Generator input, the
system can manage power automatically, which ensure household loads work
regularly and reduce use-cost.
