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 the option to prioritize either the grid or the battery—this PV system is equally well-suited for self-consumption. 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 the modules and the battery. If a higher output power is required from the inverter, additional identical units can also be connected to increase the power output.

In addition to the power electronics, the storage unit, and the solar modules, all components required for connection are 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 electricity meter, you can set up a grid-tied installation and monitor your energy consumption or keep track of 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 outages or interruptions in shore power or 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’s input. This allows for the connection of loads—such as a water heater—that should not be drained by the battery.

The unit is shipped preconfigured and optimized for the included components

The MultiPlus-II offers an extremely wide range of configuration options, just as its applications are diverse.
