4. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your solar charge controller. Please follow these steps carefully:

1. Safety First: Before wiring, ensure all power sources (solar panels, batteries) are disconnected. Do not close the circuit breaker or fuse until all connections are complete.
2. Mounting: Mount the controller vertically on a flat, non-flammable surface in a well-ventilated area, away from direct sunlight, high temperatures, and moisture. Ensure adequate clearance around the controller for heat dissipation.
3. Battery Connection: Connect the battery cables to the controller's battery terminals (17) first. Ensure correct polarity (+ to + and - to -). It is highly recommended to install a fuse (1.25 to 2 times the rated current of the controller) on the battery side, no more than 150mm from the battery.
4. PV Array Connection: Connect the solar panel cables to the controller's PV terminals (16). Ensure correct polarity. The PV reverse polarity alarm indicator (13) will alert you if connected incorrectly.
5. Load Connection (Optional): If using the load output, connect your DC load to the designated load terminals. Note that this model primarily focuses on battery charging and may not have direct load terminals for power output. If an inverter is to be connected, connect it directly to the battery, not to the load side of the controller.
6. Grounding: Connect the grounding terminal (4) to an earth ground.
7. Optional Connections:
   • Remote Temperature Sensor (RTS): Connect the RTS to the RTS Port (11) for accurate battery temperature compensation.
   • Remote Battery Voltage Sensor (RBVS): Connect the RBVS to the RBVS Port (8) for precise battery voltage measurement.
   • Communication: Connect the RS485 port (10) to a PC, MT-50 remote meter, or other monitoring devices using the appropriate cable.
8. Power On: Once all connections are secure and verified, close the battery circuit breaker/fuse, then the PV array circuit breaker. The controller will power on and begin operation.
