The solar controller adopts high speed CPU microprocessor and high precision A/D analog-to-digital converter, which is A microcomputer data acquisition and monitoring control system.
Both real-time acquisition photovoltaic system rapid current work status, acquire the information of PV station work at any time, but also the historical data of accumulated PV station in detail, to assess the rationality of the PV system design and test the reliability of the system components quality provides accurate and sufficient basis.
In addition, the solar controller also has serial communication data transmission function, which can centralize and control multiple photovoltaic system sub-stations.
The solar panel is a photovoltaic device (mainly a semiconductor material) that produces an electric current when it is exposed to light.
Due to the material and the properties of light and limitations, and its curve are generated by the current volatility, if will be generated by the current directly into electricity directly to load or inside of the battery power supply, is likely to cause damage to battery and load, severely reduces their life.
So we must first into the current solar controller, using a series of special chip to adjust on the digital circuit and join the multistage charging and discharging protection, at the same time adopt unique control technology "the adaptive three-stage charging mode", ensure running safety and service life of the battery and load.
When the load is supplied, the current of the accumulator is transferred to the solar controller, and after its adjustment, the current is sent to the load.
The purpose of this is to stabilize the discharge current;
The second is to ensure that the battery is not discharged;
Third, a series of monitoring and protection can be carried out on load and battery.
