220vac Off Grid Solar Power System 48V Ground Rooftop

5kw 48vdc 220vac 380vac Off Grid Solar System Ground Rooftop Whole Set Commercial
 
Description 
Off Grid Solar System uses solar panels to convert sunlight into electricity, and then enters the solar charge/discharge control cabinet to charge the battery pack (lead-acid battery/li-iron phosphate battery) through the sink box, and finally the solar off grid inverter power supply is used to supply power to the user load through the AC output distribution box, which runs independently of the national grid. The photovoltaic array converts solar energy into electrical energy when there is light, and stores the electricity for the battery pack through the solar controller; when there is no light, the battery pack discharges through the solar controller to supply power to the DC load, and can also reverse the discharge into AC power through the inverter to supply power to the AC load.
