Mastervolt Mass Combi Inverter Charger 24/1800-35 230V

High yield and more power from your batteries

The exceptionally reliable Mastervolt Mass Combi Inverter Charger offers a lot of power at a highly competitive price. The powerful 3-step+ battery charger guarantees maximum battery life and can simultaneously charge two battery banks. And what’s more the inverter with high peak power starts even the heaviest loads. A built-in distribution system switches between grid and inverter power, while two separate AC outputs allow users to connect critical loads to a preferred group.

Grid connected solar power system with energy storage

The Mastervolt Mass Combi Inverter Charger enables the expansion of a grid-connected solar power system with energy storage in batteries. This way the majority of the generated energy is used, and users are less dependent on the electricity grid. In this setup, the Mass Combi is part of a MasterBus controlled system.
