The solar charge controller is control device which can control solar panel and transform solar energy into electricity then store to the battery bank .It can not only supply normal power for the areas with poor or even without electricity, like in the mountains, pastoral, border, coastal island. But also can be used as DC power of the Mobile Communication Base. Solar charge controller is the most important part in off-grid system, whose performance has much effect on life expectancy and operation of the whole system, especially the battery expectancy. Life span of battery will be shortened by over charge or over discharge in any case.
Features:
1. Perfect protection function, thus the system has higher reliability.
2. Check all operation parameters from LCD display.
3. Voltage limiting and current-limiting charge mode, ensures battery in the best charging status.
4. PWM stepless unload mode, which burn the excess power, making the battery charging in best status.
Opitional funcations:
Temperature compensation function.
RS communication function: RS232/RS485/RJ45/GPRS are optional communication ports.
