Offgridtec HomePremium M UPS solar system 13500Wp US3000 21kWh 3-phase with electricity meter

Extremely Versatile All-in-One Package

The Offgridtec® HomePremium series is a true all-rounder offering unbeatable value for money. In addition to use as a UPS backup solution with the option of grid or battery priority, this PV system is equally suitable as a self-consumption unit. The performance potential of this solar system is virtually limitless – expansions on the module or battery side are possible depending on individual needs and upon request. If higher output power is required at the inverter, additional identical devices can be connected to increase output.

In addition to the power electronics, storage, and solar modules, all components required for connection are included – except for the solar module mounts, which must be ordered separately. All other components are plug and play – no tedious connector assembly required – just plug in and you're done. Depending on your selection, the system is delivered with or without a power meter.

Extended Use of Your HomePremium System

The HomePremium system is delivered with or without the Victron power meter and cable. However, a power meter and connection cable are mandatory for setting up an Energy Storage System.

With this meter, you can install the system grid-parallel and monitor your energy consumption and control your energy costs. Thanks to phase compensation, you can even use the 3-phase meter for 1-phase systems. This allows seamless integration of decentralized energy sources and loads into the existing power grid.

Maximum Flexibility Thanks to Two AC Outputs

The main output ensures uninterrupted operation. In case of a power failure or interruption of shore/generator power, the MultiPlus-II takes over power supply to connected loads. The switchover is so fast (under 20 milliseconds) that uninterrupted operation of computers and other electronics is ensured. The second output only provides power when AC is available at the input. Consumers that should not discharge the battery, such as a water heater, can be connected here.
