Feature: 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 99% Temperature Compensation Factor: -2mv/°C 2V (default) Operating temperature: -10°C to +65°C Waterproof rating: IP21 Altitude: ≤3000m Size: Approx. 214 x 115 x 50mm / 8.43 x 4.53 x 1.97in . Package List: 1 x Solar Charge Controller4 x Screw4 x Holder1 x Instruction Manual Note: 1. 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.
