Offgridtec® HomePremium UPS solar system 4500Wp 7kWh LiFePo4 storage 1-phase with electricity meter

Extremely Versatile Complete Package – Your High-Performance All-in-One Solar Solution with High-Quality Premium Components for Maximum Energy Independence

The Offgridtec® HomePremium Series is a true all-rounder offering unbeatable value for money. In addition to serving as a UPS backup solution with a choice between grid priority and battery priority, this PV system works just as well as a self-consumption system. There are virtually no limits to the performance of this solar system—depending on your personal needs and upon request, expansions are possible for both modules and batteries. If a higher output power is required at the inverter, additional identical units can also be connected to increase power.

In addition to the power electronics, the storage unit, and the solar modules, all components required for connection are also included in the scope of delivery, with the exception of the solar module mounts, which must be ordered separately. Depending on your selection, the system is delivered with or without an electricity meter.

Advanced Use of Your HomePremium System

The HomePremium system is available with or without a Victron energy meter and cable; however, the energy meter with connection cable is required to set up an energy storage system (ESS).

With this energy meter, you can set up a grid-tied installation and monitor your energy consumption or control your energy costs. Thanks to phase compensation, you can also use the 3-phase meter for 1-phase systems. This makes seamless integration of decentralized energy sources and consumers into the existing power grid a breeze.

Maximum flexibility thanks to two AC outputs

The MultiPlus-II provides uninterrupted operation by automatically taking over the power supply to loads in the event of grid failures or interruptions in shore/generator power. The switchover occurs in less than 20 milliseconds to ensure continuous operation of electronic devices. A second output supplies power only when AC power is present at the MultiPlus-II input. This allows for the connection of loads such as a water heater that should not be discharged from the battery.

Delivery is configured and tailored to the included components

The configuration options on the MultiPlus-II are extremely diverse, as are its applications. The configuration options on the MultiPlus-II are extremely diverse, as are its applications. We have already made the most essential settings for you—the system is therefore ready for immediate use without further configuration. If you order the version with a power meter, we will set up the system directly as an ESS. If you order the version with a power meter, we will set up the system directly as an ESS.
