Off-grid photovoltaic power generation system is widely used in remote mountainous areas, non-electric areas, islands, communication base stations, street lamps and other application places. Photovoltaic phalanx converts solar energy into electric energy when there is light, and supplies power to the load through the solar charge and discharge controller, and charges the battery pack at the same time; When there is no light, the battery pack supplies power to the DC load through the solar charge and discharge controller, and at the same time the battery supplies power directly to the independent inverter, which inverts into alternating current through the independent inverter to supply power to the alternating current load.
Solar system classification: Solar street lamp, solar monitoring system, solar household system, solar off-grid power station, etc. We can design a configuration plan that meets the customer's needs according to the customer's usage time, load size and other requirements.
Off-grid photovoltaic system generally consists of solar panel, solar charge and discharge controller, battery pack, off-grid inverter, DC load and AC load, etc.
The construction period of solar power generation system is short, convenient and flexible, and the capacity of solar matrix can be added or reduced arbitrarily according to the increase or decrease of load to avoid waste.
There are intermittence and randomness in ground application. The power generation is related to climatic conditions, and cannot or rarely generates electricity at night or in rainy days;
The energy density is relatively low. Under standard conditions, the solar radiation intensity received on the ground is 1000W/M ^ 2. Large-scale usage requires a large area;
The price is still relatively high, 3~15 times that of conventional power generation, and the initial investment is high.
