NDS Energy PWS GOLD 12V 30A 3 in 1 Hybrid Charger - DC to DC, MPPT & Battery Charger

The NDS Power Service Gold unit is a 3-in-1 hybrid charging system, ideal for use in motorhomes and campervans, and boats. It will take care of the leisure battery by charging from the alternator (when the engine is running), from a solar panel (up to 250W) and from 240V mains as well. It can be used with any kind of lead-acid battery - Gel, AGM, flooded acid and LiFePO4 lithium batteries.

Charging is done in 5 stages including desulfation (not when set for lithium), ensuring a full recharge, as well as improving the battery's general performance and extending its life.

Installation of the Power Service Gold charger is straightforward and detailed instructions are supplied.

Technical journalist Peter Rosenthal installed a Power Service Gold charger in his self-built campervan and wrote about the installation in MMM, the UK's leading motorhome magazine. You can read the article by clicking on the link below.
