20kW Solar Charge Controller With RS232 Communication Function

Solar controller is control device which can control solar panel and transform solar energy into electricity then store to   the battery bank. Solar 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. Or life span of battery will be shortened by over charge or over discharge.

·Superior military-grade components to ensure the product stability.

·Perfect protection function, thus the system has higher reliability.

·Check and set all operation parameters as requirement from LCD display.

·PWM stepless unload mode, which burn the excess power into Dump load, making the battery charging in best status.
