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.
