3. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your solar charge controller. Always ensure all connections are secure and correct before applying power.
3.1 Connection Steps
- Connect the Battery First: Always connect the battery to the charge controller before connecting the solar panel. Ensure correct polarity (positive to positive, negative to negative).
- Connect the Solar Panel: After the battery is connected, connect your solar panel(s) to the controller. Ensure correct polarity.
- Connect the Load (Optional): If using a DC load directly from the controller (not recommended for this model as it primarily charges batteries), connect it last.
Important Note: This controller is designed for 12V/24V batteries only. Do not connect higher voltage batteries. For safety, always connect the battery first, followed by the solar panel.

To select the correct battery type, long-press the 'BAT' button. The controller will cycle through the available battery types (e.g., SEL, GEL, F04). Select the type that matches your connected battery for optimal charging.
| Charging Type | SEL (Sealed Lead-Acid) | GEL | F04 (LiFePO4) |
|---|---|---|---|
| Boost Charging | 14.4V | 14.2V | 14.4V |
| Float Charging | 13.8V | 13.8V | 14.0V |
| MPP Tracking Return | 13.2V | 13.2V | 13.2V |
5. Maintenance
The PowMr 15A MPPT Solar Charge Controller is designed for low maintenance. However, regular checks can ensure optimal performance and longevity:
- Inspect Connections: Periodically check all wiring connections for tightness and corrosion. Loose connections can lead to power loss or overheating.
- Clean the Controller: Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning. Do not use liquid cleaners.
- Ventilation: Ensure the controller has adequate ventilation to prevent overheating, especially during peak charging periods.
- Environmental Conditions: While designed for various temperatures, avoid exposing the controller to extreme moisture or direct sunlight for prolonged periods if possible.
6. Troubleshooting
If you encounter issues with your PowMr 15A MPPT Solar Charge Controller, consider the following basic troubleshooting steps:
- No Display/No Power: Check battery connections and ensure the battery has sufficient voltage. Verify solar panel connections.
- Battery Not Charging: Confirm solar panel is receiving adequate sunlight. Check all connections for proper polarity and tightness. Ensure the correct battery type is selected on the controller.
- Overheating: Ensure the controller is in a well-ventilated area and not covered. Reduce load if possible.
- Error Codes: Refer to the LCD display for any error codes. Consult the manufacturer's support for specific code meanings if not detailed in this manual.
For persistent issues, please contact Temank customer support.
