Features 1High 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. 2Multiple 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. 3Full 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. 4Intelligent Heat Dissipation: The solar charge controller has an intelligent fan that turns on at > 45C and off at < 40C 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. 5Over 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.

As this controller handles voltages that exceed the maximum limits for human safety. 2. There are no internal parts of this controller that require maintenance or servicing. Therefore do not attempt to disassemble or repair the controller. 3. Install the controller indoors and avoid exposure of parts and ingress of water. 4. During operation the radiator may reach very high temperatures. Therefore install the controller in a place with excellent ventilation. 5. It is recommended that a fuse or circuit breaker be installed outside the controller.6. Ensure that the PV array and the fuse or circuit breaker near the battery terminals are disconnected prior to installation and wiring. 7. After installation check that all connections are secure and reliable to avoid loose connections that could cause a hazard.
