Operating Instructions
The Solar Battery Charger Pro features a built-in MPPT charge controller and a 3-stage charging process to optimize battery health and lifespan.
Charging Process (3-Stages)
- Bulk Stage: Charges the battery at the maximum current until it reaches approximately 80% of its capacity.
- Absorption Stage: Charges the battery at a constant voltage, gradually reducing the current as the battery approaches full charge.
- Float Stage: Maintains the battery at a safe voltage, compensating for self-discharge and keeping the battery fully charged without overcharging.
LED Indicator Status
The integrated LED light provides visual feedback on the charger's operational status:
| LED Status | Meaning |
|---|---|
| Blink Green | Sunshine is effective (Not Active yet) |
| Blink Red | Working to charge battery (Activated) |
| Solid Green | Battery is fully charged |
| Solid Red | Error: Reversed Polarity |

Maintenance
Regular maintenance ensures optimal performance and longevity of your solar charger:
- Cleaning: Periodically clean the solar panel surface with a soft, damp cloth to remove dust, dirt, or debris that may obstruct sunlight. Do not use abrasive cleaners.
- Connections: Inspect all cable connections regularly to ensure they are secure and free from corrosion.
- Storage: If storing the charger for an extended period, disconnect it from the battery and store it in a cool, dry place away from direct sunlight.
Troubleshooting
If you encounter issues with your solar battery charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No LED activity | Insufficient sunlight; Loose connections; Faulty battery. | Ensure panel is in direct sunlight; Check all cable connections; Test battery voltage. |
| Solid Red LED (Reversed Polarity) | Battery connections are reversed. | Immediately disconnect and reconnect the alligator clips, ensuring red is to positive (+) and black to negative (-). |
| Battery not charging effectively | Panel obstructed; Battery too deeply discharged; Incorrect battery type. | Clear obstructions from panel; For deeply discharged batteries, a conventional charger may be needed first; Ensure battery is 12V lead-acid type. |
