-
Setting Steps
-
Connect the controller to the photovoltaic panel first, press and hold the up/down button until the LED digital tube flashes.
-
Adjust to the corresponding charging voltage with +/- buttons, the display stops flashing and save the setting automatically.
-
-
Standard Full Charge Voltage
-
Lead-Acid: 14.4V * S (S = number of battery strings)
-
LiFePO4: 3.65V * S (S = number of battery strings)
-
Ternary Li-ion: 4.2V * S (S = number of battery strings)
-
Important: Solar panel open circuit voltage CANNOT exceed battery full charge voltage.
-
Step 1: Connect solar panel positive wire to controller's positive port (solar panel icon).
Step 2: Connect solar panel negative wire to controller's negative port (solar panel icon).
Step 3: Connect battery pack positive wire to controller's positive port (battery icon).
Step 4: Connect battery pack negative wire to controller's negative port (battery icon), the system starts automatically with sunlight.
Core Usage Recommendations
1. Do not overload the controller, install it in a well-ventilated environment for heat dissipation.
2. Install a switch between solar panel/battery and controller to prevent sparking during wiring.
3. Fully charge the battery pack at least once a month to avoid permanent battery damage.
4. 18V solar panel (22V open circuit) in series/parallel, 36V solar panel (44V open circuit) in parallel for multi-panel use.
-
Battery pack stores large energy, prohibit short circuit, use insulated tools when wiring and handling.
-
Battery pack produces flammable gases, keep away from open flames and ensure good ventilation for storage.
-
Keep children away from the controller and battery pack to avoid safety accidents.
-
Do not replace the fuse with higher rating or copper wire, follow the battery manufacturer's safety recommendations.
-
Charging stops automatically when the display shows 0.0A, which means the battery is fully charged.
