Installation & Safety Notes
- ALWAYS connect battery first. Ensure enough battery voltage so the controller can recognize the correct system voltage. NEVER connect the solar panel array to the controller without a battery. The disassembly sequence is the reverse of the wiring order.
- DO NOT connect any inverter / wind / alternator or charger into the charge controller. Connect the inverter directly to the battery.
- Ensure solar input voltage is 3V or more higher than the battery voltage, and keep total input power within the supported range. If input power is too low, charging current may be close to zero when the controller is in float charge.
- Charging indicator and charging current may switch on/off in low light (cloudy weather or evening); this is normal.
- If the controller buzzes, the fan is operating for heat dissipation.
- DO NOT install the controller in direct sunlight to avoid power loss due to overheating. Keep space for heat dissipation (approx. 20cm) and remove clutter around the unit to reduce interference.
- Ensure all connections are tight. DO NOT allow the positive (+) and negative (-) battery terminals to touch.
