The Sunsport 10 Dual-Battery Controller is a marine option specifically designed for boats and charges two isolated batteries from one panel.

Completely sealed for protection from the harsh salt water environment.

Automatic nighttime shutdown with an intelligent design means that, in the dark, the Sunsport 10 uses absolutely zero power.

Ideal for PV systems where efficiency is important.

Boaters can leave it connected all winter without draining the batteries. Other controllers, which have a standby current draw, will drain the battery over the winter if they receive little or no solar input.
