Description
As photovoltaic cells generate energy when exposed to sunlight, they can provide a sustainable energy source to charge the batteries in your application.
All Mastervolt’s knowhow in the field of solar power has been included in the Solar ChargeMaster, which offers maximum efficiency from the often irregular availability of sunlight. The design provides a pure charge current in all conditions while the 3-step charging method ensures a safe charging process and a longer lifespan for your batteries.
