Mass Combi 24/1800-35 - Charger-Inverter Combi - NautiRadar - Marine Systems Electronics and Telecommunications Ltd

The powerful 3-step+ battery charger guarantees maximum battery life and can simultaneously charge two battery banks. The inverter with high peak power starts even the heaviest loads, with the Mass Combi 24/1800-35 being easily sufficient for your espresso machine.

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
Mass Combi 24/1800-35 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 24/1800-35 is part of a MasterBus controlled system.

Benefits of the Mass Combi 24/1800-35:

• Compact, lightweight and no hum thanks to HF technology.
• High yield and more power from your batteries.
• Intelligent 3-step+ battery charger with low DC ripple current for fast charging times and long battery life.
• Charges two individual battery banks simultaneously.
• Quiet, powerful inverter with 200 % peak power.
• Power Assist: extra power assistance from the batteries in case of limited grid or generator power (prevents blown fuses).
• Pure sine wave energy prevents failures and damage to sensitive equipment such as adapters.
• Dual AC outputs to separate critical equipment from heavy loads.
• Higher yields possible via parallel switching (only for 2200 and 2600 W models).
• Professional connections ensure fast installation and operational security.
• CE approved and E-marking for mobile applications.
