With the continuous development of science and technology, solar inverters have been widely used in our life, solar inverters exist a solar AC power generation system, and with the continuous diversification of buildings in today’s life, solar inverters also need to follow the new generation. It is likely that most people understand solar energy, not inverters.
*Overview of solar inverter
The solar system in solar inverter is mainly composed of battery panel, charge controller, inverter and battery, which most people know, however, the inverter may be less exposed to people, the inverter is actually a power conversion device, so to speak, is to reverse the DC power in the battery into AC power such a device. Inverters can be classified according to the excitation method, mainly self-excited oscillating inverter and other-excited oscillating inverter.
Solar inverters are currently used worldwide as central inverters, string inverters, multi-string inverters and module inverters. Central inverters are generally used in large PV power plant systems, mainly because of their high system power and relatively low cost; string inverters are among the most popular inverters in the current market, as they can track the maximum power peak at the DC side, and the technical cost has been reduced a lot; multi-string inverters can be said to be a combination of centralized and string inverters. Multi-string inverters can be said to concentrate the advantages of centralized inverters and string inverters; module inverters are mainly connected to each PV module and an inverter, so that the system works better together when working.
*The role of solar inverters
Solar inverters are divided into stand-alone solar power inverters and grid-connected solar power inverters, while stand-alone solar power inverters are mainly used in remote areas without household electricity and for individual household users, and grid-connected solar power inverters are mainly used in desert power stations and urban rooftop power systems.
In fact, the overall function of solar inverter is to get the corresponding sinusoidal alternating current through the full-bridge circuit, and then use the SPWM processor to get the corresponding sinusoidal alternating current through modulation, filtering and boosting, etc., and finally to supply the end customers who need to use electricity. Can use the DC battery stored in the battery in order to use, this is the role of the solar inverter, and therefore makes the solar inverter become the core components of the photovoltaic wind power generation system, but the important thing is the low cost of new energy generation, solar inverter to run at high speed.
