When you connect a solar panel to a 12V or 24V battery, you will almost certainly need a regulator. This will control the energy coming from the panel and get it to the battery in the most efficient way. There are different types of regulator and, as with most things, you get what you pay for. We have a variety of regulators including basic ones and sophisticated MPPT models which will charge your battery significantly faster, especially in less than ideal conditions. Most of our regulators will charge the vehicle’s starter battery as well as the leisure batteries.

Our regulators come from Votronic, the leading German manufacturer and NDS who also make our solar panels, lithium batteries and more. 

All our regulators can be connected to a display panel or “solar computer” which will enable you to see exactly how your solar installation is performing and how your battery is responding. All monitors show both current activity & voltage and Votronic models also keep a record of total energy generated. So you can work out when your panels have generated enough power to have paid for themselves!

NOTE: Unlike many solar controllers, all NDS and Votronic models have dual outputs so that the vehicle's starter battery can be charged as well as the leisure battery.

Some Votronic regulators can be connected to EBL's to check if the regulator can be connected to your EBL please click here
