01: AC priority/Citypower priority:
When city power is available, the inverter will work AC
output, city power will supply power to appliances.The city
power and sun power will charges 2 kinds power to battery.
When city power failed, sun power will charges the battery
and use battery power(solar power) to take the appliances.
02: energy saving mode
load power ≤10% off the machine, ≥11% -100% turn on
03: solar power priority/Battery priority
When it have sun power, sun power charges the battery and
supply power to the appliances. When it does not have sun
power or battery voltage ≤10.5V, inverter will automatic use
city power to take the appliances, When battery voltage
reach 13V inverter will use use battery power and sun power
