Offgridtec® HomePremium S UPS solar system 2250Wp 3.5kWh LiFePo4 storage 1-phase with electricity meter

Extremely versatile complete package—your powerful all-in-one solar solution with high-quality premium components for maximum energy independence

The Offgridtec® HomePremium series is a true all-rounder at an unbeatable price-performance ratio. 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, although an energy meter with connection cable is required for setting up an energy storage system.

With this electricity meter, you can set up a grid-parallel installation and then monitor your energy consumption and 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 at all.

Luxen Solar 450W Full Black Solar Module

The bifacial 450W Full Black solar module from the Luxneri N5 series by Luxen Solar (MPN LNDX-450ND) sets new standards in solar technology. It combines innovative technologies such as LECO N-TOPCon cell technology and a 96-cell half layout to maximize efficiency. In addition, SMBB half-cut cell technology is used to optimize performance.

Half-cell technology

In half-cell technology ("Half-Cut"), conventional silicon cells are cut in half using a laser. The resulting halves are then connected in parallel at the center, which reduces resistance losses and increases the performance of the solar module.

Bifacial cells

Bifacial modules offer a decisive advantage thanks to their transparent backs and special cell technology—they also utilize reflected light. This leads to a significantly increased energy yield and makes these modules a particularly efficient choice for your solar system.

The heart of the system – the Victron MultiPlus-II 48/3000

The MultiPlus-II 48/3000/70-50 from Victron Energy (MPN PMP482305010) combines classic MultiPlus components with an external current sensor and integrated anti-islanding function. This extends the PowerControl and PowerAssist functions to 100A and enables use in ESS applications.

With a 3000 W inverter (2400 W with linear load) and a 48 V battery charger of 35 A, this Multiplus-II is optimally dimensioned. A 32 A transfer switch allows quick switching between AC connections for maximum flexibility

Performance features and characteristics of the MultiPlus-II 48/3000

• PowerControl and PowerAssist – increase mains or generator power
• built-in anti-islanding function and connection option for external current sensor (optional)
• Can be used as a backup device in grid-connected systems
• VE.Bus interface for parallel and three-phase operation
• Remote monitoring and system integration
• Approved according to VDE-AR-N 4105

Technical data

• 3000 W power with non-linear load - 2400 W continuous load - 5500 W peak power
• for 48 V battery voltage, 32 A transfer switch, and 35 A battery charger
• Output voltage: 230 VAC, frequency: 50 Hz
• Max. efficiency: 95%
• Protection class IP22

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. We have already made the most important settings for you, so the system is 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.
