Power supply, battery and inverters

In this category are the accessories for powering the boat electrical system. Nautical batteries are born to be resistant to vibrations and oscillations during navigation although it is always recommended to position them so that they are as stable as possible. The boat chargers allow you to charge any kind of battery and, via bluetooth, you can check the charge status directly from your smartphone. We also offer flexible solar panels for boats that can be installed on t-tops and on deck as they can be walked on. In our shop there are also the inverters for boats that allow you to switch the DC voltage on board into alternating voltage of 220 V for the power supply of the electrical utilities that require it, our offer also offers integrated inverter charger systems. Our charge distributors allow you to charge up to 4 batteries from a single input. Nautical battery switches are capable of breaking electrical circuits with high operating powers. The battery boxes are useful for fixing the battery so that it does not undergo overturning which can lead to the loss of liquids and acids. In this section there are also marine electrical cables and battery cables together with terminal terminals and cable lugs. Accessories for dock systems such as watertight sockets, plugs and cables are also available.
