The basic function of the solar charge and discharge controller is to control the battery voltage and open the circuit, and when the battery voltage rises to a certain extent, stop charging the battery. Old-fashioned controllers mechanically turn on or off the control circuit, stop or start the power supply to the battery.
In most PV systems, solar charging controller are used to protect batteries from overcharging or overdischarging. Overcharge may cause the electrolyte in the battery to vaporize and cause failure, while overdischarge of the battery may cause premature failure of the battery. Overcharge and overdischarge may damage the load. Therefore, the controller is one of the core components of the photovoltaic power generation system, and is also the main part of the balance system BOS (Balance of System).
In short, the functions of solar charging controller can be divided into:
1, power regulation function;
2. Communication Function: 1 Simple Indicator Function 2 Protocol Communication Function such as RS485 Ethernet, Wireless and other forms of background management;
3, perfect protection function: electrical protection reverse connection, short circuit, overcurrent and so on.
