TG series single phase inverter with mppt controller

In China, the research and development of photovoltaic inverters has been carried out since the 1960s, and now there are specialized companies researching and producing inverters. Due to the relatively late start of the market, domestic photovoltaic inverter manufacturers are generally small in scale, and there is a certain gap with foreign first-class enterprises. At present, there are many domestic manufacturers of inverters, but not many manufacturers specialize in researching and developing inverters for photovoltaic power generation systems. The photovoltaic inverter technology and output of domestic photovoltaic enterprises have shown an upward trend year by year. With the installation of large-scale photovoltaic system power stations and the continuous increase of photovoltaic inverter investors, the interest rate will definitely decline, but the quality of large-scale grid-connected inverters still needs to be tested by the market.

The key technology of the inverter mainly includes the topology structure of the main circuit, output voltage control, control algorithm, harmonic content suppression, anti-shock load capacity, system protection measures, etc.

The topology of the main circuit mainly includes two parts: the front-stage booster circuit and the post-stage single-phase inverter circuit. Generally, the output AC voltage of the inverter is higher than the photovoltaic voltage, so a front-stage booster circuit is required
