The photovoltaic power generation system mainly includes a grid-connected system and an off-grid system. The grid-connected system transmits the electric energy generated by the photovoltaic system to the national grid in parallel. The grid-connected system is mainly composed of photovoltaic modules, inverters, power distribution box and other accessories. The off-grid system operates independently and does not need to rely on the public power grid. The off-grid system needs to be equipped with a battery with energy storage and a solar controller, which can ensure the stability of the system power and can be used when the photovoltaic system does not generate electricity or is insufficient in continuous cloudy days. power down the load.

The on grid inverter should not only convert the DC output from the solar photovoltaic power generation system into AC, but also control the voltage, current waveform, frequency, phase, and synchronization of AC, but also solve the problem of the power grid.

The off grid inverter adopts a complete system solution of modular components. off grid inverter is composed of some manageable building blocks, such as XW inverter/charger, automatic generator start module, solar charge controller, and system control panel.

Lithium batteries can be roughly divided into two categories: metal lithium batteries and lithium-ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable.

The household inverter is a common device in household appliances such as air conditioners, computers, refrigerators, etc. Its main function is to realize the conversion of different types of currents.

The function of a household inverter is to convert DC power, that is, the current in some batteries and accumulators, into a tool for AC power. In layman's terms, a household inverter is a device that helps convert direct current into alternating current.
