Detail

The photovoltaic controller is mainly used in the power generation system equipped with photovoltaic cells. It is used to control the charging of the photovoltaic cells to the battery and the discharge of the battery to the load.

 

Features:

■LCD display, photovoltaic input voltage, battery voltage, charging current, discharging current, battery temperature, controller working status and other parameters can be displayed in real time;

p>

■Users can set the parameter values ​​according to the actual situation. After the parameter value is modified, it will be saved to the EPPROM in real time, and it does not need to be reset after restarting;

■The number of battery cells is automatically detected, and can also be set manually;

■Using PWM charging circuit, the voltage drop loss of the charging circuit is small, and the charging efficiency is higher;

■With float voltage temperature compensation function, it can automatically adjust the float voltage according to the battery temperature;

■With battery reverse connection protection function, the controller does not work after the battery is reversely connected, and can work normally after recovery;

■There is a dedicated battery temperature detection port, which is convenient for external battery temperature detection; reserved control port is convenient to expand the controller function according to actual requirements;

■There are a variety of load control methods, which can be set to automatically and manually switch the load. There are light control mode and various time control modes for users to set and choose, which can meet the needs of different users. demand;

■With various protection functions, such as overvoltage, undervoltage, overcharge, overdischarge, overload, overtemperature, load short circuit, battery open circuit, photovoltaic lightning protection, etc. function;

■The battery has a fast charging function after being over-discharged. After the battery is fully charged, it will automatically switch to the floating charging mode, which will cause little damage to the battery and prolong the service life of the battery;

■The RS485 interface can be expanded according to user needs.
