Product detail:
The role of the 12V 24V solar charge controller The basic function of the solar controller is to control the battery voltage and turn on the circuit. When the battery voltage rises to a certain level, it stops the battery charging. Controllers are used in most photovoltaic systems to protect batteries from overcharging or overdischarging. Overcharging may vaporize the electrolyte in the battery, causing failure, and overdischarging the battery will cause the battery to fail prematurely. Overcharging and overdischarging may damage the load, so the controller is one of the core components of the photovoltaic power generation system, and it is also a balancer. The main part of the system BOS (Balance Of System). In simple terms, the role of the solar controller can be divided into: 
1. Power adjustment function. 
2. Communication function: simple indication function and protocol communication function, such as RS485 Ethernet, wireless and other forms of background management. 
3. Perfect protection functions: electrical protection, reverse polarity protection, short circuit protection, overcurrent protection, overcharge protection, overdischarge protection, etc.
