Common Questions
What battery types are compatible with this controller?
This controller is designed to work seamlessly with 12V sealed, gel, and flooded lead-acid battery types. You can select your specific battery type for optimised charging.
What size solar panel can I connect?
The controller is suitable for solar panels up to 60W. For optimal performance, we recommend pairing it with solar panels that have a maximum power voltage (Vmp) between 17-20V.
Can I charge my phone using this controller?
Yes, the controller features a dedicated 5V USB port with a 1.2A output, allowing you to charge smartphones, tablets, and other compatible USB devices directly from your solar power system.
What are the benefits of PWM charging technology?
PWM (Pulse Width Modulation) charging helps to increase your battery's charge acceptance, recover lost capacity, and significantly extend its overall lifespan by carefully regulating the charging current and voltage.
Installation Notes
- Connect the battery to the controller first.
- Then connect the solar panel to the controller.
- Finally, connect any 12V DC loads to the controller.
- Ensure correct polarity for all connections to prevent damage.
- Mount the controller in a dry, well-ventilated area, away from direct sunlight.
- Refer to the included instruction manual for detailed wiring diagrams and setup procedures.
Before You Buy
- Verify your battery system is 12V.
- Confirm your solar panel's maximum power output is 60W or less.
- Check your solar panel's Vmp (Max Power Voltage) is within the recommended 17-20V range for optimal performance.
- Consider an MPPT controller if your solar panel voltage is significantly higher than 25V for maximum energy harvest.
- Ensure you have appropriate cabling and fuses for your system.
- This controller is for lead-acid batteries (sealed, gel, flooded) only.
Always verify product specifications and compatibility with your existing solar components before purchase. This product includes a 1-year warranty for peace of mind.
