Common Questions
What type of batteries can this kit charge?
This kit is designed to charge 12V DC batteries with a capacity larger than 15Ah. The controller is compatible with sealed, gel, and flooded lead-acid battery types, which can be selected by the user.
Is the solar panel and controller waterproof?
The 20W solar panel and its junction box are fully waterproof and weather-resistant, making them suitable for permanent outdoor installation. However, the 5A solar charge controller is not waterproof and must be installed indoors or in a protected, dry environment.
Can I connect 12V loads directly to the controller?
Yes, the controller includes dedicated load terminals for connecting 12V appliances such as lights. It features an on/off switch for the load. Ensure the total current drawn by the load does not exceed 5A.
What kind of warranty is included?
The kit is covered by a 1-year standard warranty. The solar panel specifically carries a performance guarantee of 90% power for 10 years and 80% for 25 years.
Installation Notes
- A comprehensive user manual is included with the kit, providing clear installation guides and detailed instructions.
- The solar panel should be mounted with approximately 1.0 to 1.5 cm of clearance underneath for optimal cooling and performance.
- Ensure the solar charge controller is installed in a dry, protected indoor location, as it is not waterproof.
- The 2m battery cable with crocodile clips offers a quick and secure connection to your 12V battery.
Before You Buy
- Verify your battery type (sealed, gel, or flooded) to ensure correct settings on the charge controller.
- Confirm the power requirements of your 12V loads to ensure they do not exceed the controller's 5A limit.
