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

Extremely versatile complete package

The Offgridtec® HomePremium series is a true all-rounder offering unbeatable value for money. In addition to its use as a UPS backup solution with a choice between mains and battery priority, this PV system can also be used as a self-consumption system. There are virtually no limits to the performance of this solar system – depending on your personal requirements and on request, extensions are possible on both the module and battery sides. If a higher output power is required at the inverter, additional identical devices can also be connected to increase the 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 holders, which must be ordered separately. Depending on your selection, the system is delivered with or without an electricity meter.

Extended use of your HomePremium system

The HomePremium system is available with or without a Victron electricity meter and cable. The energy meter with connection cable is required for setting up an energy storage system (ESS).

With this electricity meter, you can set up a grid-parallel installation and monitor your energy consumption or control your energy coststhanks to phase compensation, you can also operate the 3-phase meter for 1-phase systems. This makes seamless integration of decentralized energy sources and consumers into the existing power grid no problem.

Maximum flexibility thanks to two AC outputs

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

Delivery is configured and matched to the components supplied

The MultiPlus-II offers a wide range of settings and applications. The MultiPlus-II offers a wide range of settings and applicationswe have already made the most necessary settings for you - the system is therefore ready for immediate use without any further configuration. If you order the option with an electricity meter, we will set up the system directly as an ESS. If you order the option with an electricity meter, we will set up the system directly as an ESS.
