Q. If I disconnect the solar panel from the charge controller, can I leave the controller connected to the
battery?
A. Yes, the solar charge controller can remain connected to the battery without the solar panel.
Q. I need to shorten / extend the solar panel cable. Is this possible?
A. Yes, it’s possible. If you are extending the solar panel cable please make sure you use cable with the
same cross section and your connections are secure (soldering is recommended) and well isolated.
Q. Can the solar kit be used for positive / negative ground vehicles / boats?
A. The solar kit can be used in both positive and negative ground vehicles and boats. As per the above
note, please make sure that the solar panel (and load if you are using the load terminals of the solar
controller) are fully electrically isolated from the body of your vehicle / boat hull.
Q. What is the difference between polycrystalline and monocrystalline solar panels?
A. The difference relates to the process of solar cells manufacturing rather than product characteristics.
Monocrystalline solar panels can use the space slightly more efficiently, but polycrystalline solar panels
perform slightly better in hot weather conditions. The difference is not significant.
Q. I want to have more solar power and charge my battery faster – can I upgrade the solar kit?
A. You can easily upgrade this kit from 20W to 40W by adding a similar 20W solar panel to your same
charge controller. The output will double and the charging time will halve. See Appendix for more details.
Q. Do I need to clean my solar panel?
A. Yes. Regular cleaning increases energy yield. Always remember that any shading reduces the output.
Troubleshooting
•
Make sure your battery generates at least 6V. Disconnect any load which might be drawing
power from your battery (also disconnect your battery from the system of your vehicle / boat).
•
Disconnect the kit and leave the controller to cool for 5 min. Check all connections to ensure they
are secure and clean, check polarity of battery and solar panel and reconnect the kit (battery 1st).
•
Ensure the solar panel is exposed to sufficient light – ideally position it to face the sun
•
For more information refer to the Troubleshooting section of the solar controller manual
