DESCRIPTION
The PV power system consists of photovoltaic module matrix,
accumulator, power supply controller, DC/AC inverter, power
transmission and distribution, low-voltage power feeding net,
AC & DC loads, etc.
Photovoltaic module matrix outputs electrical energy under irradiation of sunlight, charges the accumulator group via reverse-charging preventive diode while powers DC loads. Meanwhile the output of the photovoltaic module matrix and the accumulator group goes through the controller and is connected switched into inverter's DC input end, and power is supplied to load by the inverter via distribution board. On continual overcast and rainy days when power output of photovoltaic module matrix cannot meet the requirement of normal power supply to the load, the accumulator group will power the load via inverter. Moreover, in order to monitor the performance of the entire system and operation of the equipment, this system can also be equipped with monitoring system.
