1、High Performance DSP Controller: This 60A solar charge controller is intelligent with a maximum efficiency of ≥ 98.1% and a PV utilisation rate of ≥ 99%. Built in high performance DSP controller for automatic battery voltage detection. 2、Multiple Battery Adaptation: The solar charge controller is suitable for batteries with settable lithium, lithium battery, lithium (NiCoMn) O2, vented, liquid rich, sealed, gel, nickel cadmium batteries. User programmable absorption voltage, floating voltage, low voltage disconnect, load timer, with real time energy logging. Solar and battery connectors have 2 connectors per pos and neg, 9AWG copper wire. 3、Full System Protection: The solar charge controller has a backlit LCD Dispaly PV voltage, output power, battery voltage, charge current, operating mode and temperature. the LCD display not only helps the user to view the operating data and status of the entire system, but also to quickly identify system faults and modify parameters. 4、Intelligent Heat Dissipation: The solar charge controller has an intelligent fan that turns on at > 45°C and off at < 40°C, with multiple holes for heat dissipation. The fan uses BEARING technology for an extended service life of up to 5000 hours under normal use. Suitable for caravans, commercial vehicles, boats, yachts and solar systems. 5、Over Temperature Protection: The solar charge controller uses a built in over temperature protection mechanism. When the temperature exceeds the set value, the charging current will drop in linear proportion to the temperature and stop discharging, thus inhibiting the temperature rise of the controller and effectively preventing the controller from being damaged by overheating.
