Thisproduct is mainly applied in household photovoltaic distributed grid-connected power generation systems and small-scale commercial photovoltaic power generation systems. It is connected between the grid-connected inverter and the power grid. The product has a series of protection functions including anti-islanding protection, overvoltage/undervoltage protection, input lightning protection, system overcurrent protection, power grid isolation, etc. Accurate electricity metering, transmission, and intelligent operation control are essential parts of household grid-connected power generation systems. The product has passed industry standard CCC certification and CE certification.
This product uses single-phase grid-connected technology, with an output voltage of 220V. It adopts advanced MPPT charging control methods, which can automatically track the maximum power point of the solar panel to improve the efficiency of photovoltaic power generation. The grid-connected cabinet also has safety protection measures such as DC switch circuit breakers, AC contactors, and power cable terminals to ensure safe and reliable operation of the equipment.
This product not only complies with the national energy-saving and environmental protection policies, but is also the most promising new energy product with development potential at present. It is believed that in the future, it will have increasingly wide applications.
