Automatic Recognition 20A PWM Solar Controller For Solar Power System
SR Series Advantages:
Stable performance protect the battery system, keep battery healthy and longer lifetime.
Protection:over charge,over discharge,over load,Low voltage,short circuit,reverse connect.
Charge controllers are vital components in battery-based PV systems, keeping the PV array from overcharging the batteries and optimizing charge current. Hanfong solar controller is superior in quality and compatible with most types of solar inverters. SR20 charge controller has all-around protecting functions and MPPT,MTTP function for better charging the battery and protecting electrical devices. The mutual operation feature helps user regulate the charging current, charge-off voltage, etc. The efficiency is 30% more than early-developed charge controllers.
