What is off grid system?

The off-grid photovoltaic system is generally composed of a photovoltaic array composed of solar cell modules, solar charge and discharge controller, battery pack, off grid inverter, DC load and AC load.


1. Solar panel
The solar cell module is the main part and also the most valuable component in the solar power supply system. Its function is to convert the solar radiation energy into DC energy.
2. )Solar charge and discharge controller (also known as "photovoltaic controller")
It is used to regulate and control the electric energy generated by solar cell modules. In addition, it is used to charge the battery to the greatest extent and protect the battery from overcharge and over-discharge.
It is used to store the electricity generated by solar panels during the day for use when there is no light.
4.Off-grid inverter
The off-grid inverter is the core component of the off-grid power generation system, which is responsible for converting DC into AC for AC load. Only DC load can not need the inverter
