Solar inverter is the core of the heavy

Ordinary solar photovoltaic systems are composed of many solar panels closely linked components. The panels solar inverter series first packet, then the battery array of different battery string formed parallel.
At present China's photovoltaic power generation system is mainly DC system, solar power solar inverter is about to issue to charge the battery, and the battery power directly to the load, such as Northwest China uses more solar home lighting systems and off-grid microwave station DC power supply systems are the systems. Such a system is simple structure, low cost, but because of the different load DC voltage (such as 12V, 24V, 48V, etc.), it is difficult to achieve standardization and compatibility of the system, especially the civilian power, solar inverters, mostly due to the AC load to DC power supply photovoltaic power is difficult to enter the market as a commodity.
split phase inverter is a power electronics, solar panels can convert the DC voltage to AC voltage to drive household appliances, lighting and power tools, AC load, is a key component of the entire solar system.
The inverter has two basic functions: solar inverter on the one hand is to complete the DC / AC converter connected to the grid current, on the other hand is to identify the optimum operating point to optimize the efficiency of solar photovoltaic systems. For a particular solar radiation, temperature and battery type, solar photovoltaic systems have a unique corresponding optimal voltage and current, so that the photovoltaic system to produce maximum energy.
