Solar high-frequency modified string inverter prototype clone

Date: 2016-11-16

Solar high-frequency modified string inverter is a kind of power electronic circuit, which can convert the DC voltage of solar panel to AC voltage to drive AC loads such as household appliances, lighting and motor tools. It is a key component of the entire solar power generation system. The inverter has two basic functions: on the one hand, it is connected to the grid for the purpose of DC / AC conversion, and on the other hand, it finds the best operating point to optimize the efficiency of the solar photovoltaic system. Xinxin Technology successfully cloned the solar high-frequency modified string inverter and successfully achieved its various targets. The following is a brief introduction to the performance of the inverter:


The main function:
Working mode: with mains, inverter, 2 working modes, and with PV charging function;
Protection functions: overcharge, short circuit, reverse battery connection, overload, overtemperature, overvoltage, undervoltage and other protections;
Display and setting: LCD + LED display working mode;
Efficiency: 80%.
