FAQ Q. What type of batteries can be used with this kit? A. Any sealed lead acid, gel, or flooded 12V battery (typically used in caravans, motorhomes, boats etc.) is a ppropriate for use with this kit. Q. Can this kit charge a 24V battery? A. No, because this kit is designed to charge a 12V battery. Technically, it’s possible to change solar panel connections to enable the kit to work in 24V mode; however, a qualified, knowledgeable individual should only do this. Note: unauthorized modification to 24V will void the warranty. Q. Can the kit charge two or more 12V batteries connected in parallel? A. Yes, it’s possible if the batteries have the same type and capacity and are wired in parallel as a single 12V battery bank. Q. Is there any risk that the solar kit will over charge my battery? A. One of the functions of the solar charge controller is to ensure that your battery is not over charged; therefore there is no risk of overcharge. Q. Can I extend the battery leads? A. Yes, it’s possible- please choose the same size of cable for extension. However, the longer the extension, the greater the line loss. Bigger gauge will be required for longer runs. Q. Do I need to clean the solar panels? A. Yes, it is recommended for better performance. Dust and dirt should first be swept off the panel surface using a soft brush. When the sweeping is complete, use a wet cloth to wipe the panel surface to remove remaining dirt and grime.
Q. Can rain damage the solar kit? A. The solar panels are fully waterproof (IP66 class), the controller is not.We recommend protecting the kit from rain, since water into controller may damage the internal circuitry.
