Solar power system by the solar cell matrix, combiner boxes, DC power distribution cabinets, grid-connected inverter, AC power distribution cabinets, booster composition.
(A) solar panels
Solar panels are a central part of a solar power system and the most valuable part of a solar power system. Its role is to convert the solar radiation into electricity, or sent to storage batteries, or to promote the work load. The quality and cost of solar panels will directly determine the quality and cost of the entire system.
(B) confluence box
In the solar photovoltaic power generation system will be used to confluence box, also known as the solar confluence box, solar PV combiner box, PV array lightning protection confluence box, solar power generation confluence box, photovoltaic power generation confluence box, photovoltaic lightning confluence box. In a solar photovoltaic power generation system, the combiner box is used to reduce the connection between the solar photovoltaic array and the inverter.
(C) grid inverter
In many occasions, need to provide 220VAC, 110VAC AC power supply. As the direct output of solar energy are generally 12VDC, 24VDC, 48VDC. In order to be able to provide electrical energy to 220VAC, the DC power generated by the solar power generation system needs to be converted into AC electrical energy, so a DC-AC inverter is needed. In some cases, DC-DC inverters are also required when using multiple voltage loads, such as converting 24VDC power to 5VDC power (note that this is not a simple step-down).
