TT12/2420LI-A Universal 20A Waterproof Solar Charge Controller
This controller is a new generation product developed by our company for high power solar lighting systems and small solar power systems, with features of high IP grade, wide application and simple and flexible setup and so on. The maximum discharging current can be up to 20A. The minimum charging current can be up to 10mA, which assures normal charging in the poor light in cloudy and rainy days.
This controller adopts fully sealed waterproof design and infrared remote control technology. Without buttons and equipment exposed outside, the product is really waterproof and dustproof and anticorrosive. Our controller is widely used in solar lighting systems and solar power systems. Our controller is your first choice.
