The solar controller is used in most photovoltaic systems to protect the battery from overcharge or over. Paper can cause the electrolyte of electrolyte in the battery to cause malfunctions, and the battery overlays will cause the battery to have expired, and the overcharge can be damaged, so the controller is one of the core components of the photovoltaic power generation system. It is also a balance. The main part of the system.
Simply, the role of the solar controller can be divided into:
1, power adjustment function.
2, communication function: simple indication function and protocol communication function, wireless and other forms of background management.
3. Perfect protection: electrical protection, reverse protection, short circuit protection, overcurrent protection, overcharge protection, overlay protection, etc.
