Power Service Plus 12V-40A By Alternator & Solar "Lithium" (Plus40/L)

The NDS Power Service Plus 12V 40A Alternator & Solar Charger (PLUS40-L) is a powerful 2-in-1 DC-DC battery charger and solar charge controller designed for caravans, motorhomes, campervans, boats, and off-grid vehicles.

This smart charger allows your leisure battery to be charged from both the vehicle alternator and solar panels, ensuring reliable battery charging while driving or parked.

The integrated 40A battery-to-battery charger rapidly charges the leisure battery while the engine is running, delivering up to 40 amps per hour of driving.

At the same time, the built-in solar charge controller supports solar arrays up to around 250W, allowing solar panels to maintain the battery while camping off-grid.

A microprocessor-controlled charging system manages multiple charging stages and battery types, ensuring the correct charging profile for lithium, AGM, gel, or flooded batteries.

The unit is also compatible with modern Euro 6 smart alternators, making it suitable for newer campervan and motorhome conversions.
