Note:
1. Step: Connect the system in sequence battery‑load‑PV array, and disconnect the system in reverse order. Never connect a solar panel array to the controller without a battery.
2. The battery must be connected first.
3. Do not connect any inverters, wind alternators or chargers to the charge controller.
4. If the remote temperature sensor is not connected to the controller, the battery charge or discharge temperature is set to 25℃ by default without temperature compensation.
5. The wire diameter is for reference only. If the distance between the PV array and the controller or the controller and the battery is long, larger wires can be used to reduce the voltage drop and improve performance.
