The core function of the solar controller, on (solar panels) to improve the efficiency of power generation; In (battery) better protection battery, prolong the battery working time, prolong the battery life; Reasonable protection of load equipment to lower (output, load), so that the load equipment work more stable and reliable. In simple terms, the solar controller is an automatic control equipment used in the solar power generation system to control the battery charging by the multi-channel solar battery array and the battery to supply power to the load of the solar inverter. It provides and controls the charge and discharge conditions of the battery, and controls the energy output of the solar cell module and the battery to the load according to the power supply requirements of the load, which is the core control part of the whole photovoltaic power supply system.

In most photovoltaic systems, a solar controller is used to protect the battery from overcharging or overdischarging by controlling the battery voltage and turning on the circuit, which stops charging the battery when the battery voltage rises to a certain level. So the solar controller is one of the core components of photovoltaic power generation system. Beijing Shoushan Xinda Technology Co., LTD., with more than 10 years of technical accumulation and experience, as well as domestic and foreign strong scientific research team, based on mature power electronics technology combined with the needs of the market, has launched four series of dozens of models of solar controller, inverter products and some special accessories; It can fully meet the application requirements of small and medium power off-grid photovoltaic system.

The role of solar controller can be divided into:

1, power regulation function;
2, communication function: 1 simple indication 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, etc.
