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

Extremely Versatile Complete Package

The Offgridtec® HomePremium Series is a true all-rounder at an unbeatable price-performance ratio. In addition to being used as a UPS backup solution with the option to choose between grid and battery priority, this PV system can equally well serve as a self-consumption system. The performance capabilities of this solar system are virtually limitless – depending on personal needs and upon request, both module and battery expansions are possible. If a higher output is required at the inverter, further identical devices can also be added to increase performance.

Alongside the power electronics, storage, and solar modules, all necessary components for the connection are included in the delivery, except for the solar module mounts, which must be ordered separately. All other components are plug and play – meaning there is no cumbersome plug assembly or the like – just connect and you're done. Depending on the selection, the system will be provided with or without a power meter.

Advanced Use of Your HomePremium System

The delivery of the HomePremium system is available either with or without the Victron power meter and cable, whereby a power meter with connection cable is required for the setup of an energy storage system.

With the power meter, you can perform a grid-tied installation and then monitor your energy consumption or control your energy costs. Thanks to phase compensation, you can also operate the 3-phase meter for 1-phase systems. This seamlessly integrates decentralized energy sources and consumers into the existing power grid without issues.

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. Additionally, the SMBB half-cut cell technology is employed to optimize performance.

Half-Cell Technology

In half-cell technology ("Half-Cut"), conventional silicon cells are halved using a laser. The resulting halves are then connected in parallel to reduce resistive losses, leading to increased performance of the solar module.

Bifacial Cells

Bifacial modules offer a significant advantage with their transparent backsides and specialized cell technology – they harness reflected light as well. This results in substantially increased energy yield, making these modules a particularly efficient choice for your solar installation.

The Heart of the System – 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 expands the PowerControl and PowerAssist functions to 100A, enabling its use in ESS applications.

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

Performance Features and Characteristics of the MultiPlus-II 48/3000

• PowerControl and PowerAssist – Increase grid or generator power
• Integrated anti-islanding function and optional connection possibility for external current sensor
• Can be used as a backup device in grid-tied 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 under non-linear load - 2400 W continuous load - 5500 W peak power
• for 48 V battery voltage, 32A transfer switch, and 35A 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 consumers during power outages or interruptions in land/generator power. The switching occurs in less than 20 milliseconds to ensure continuous operation of electronic devices. A second output supplies power only when there is AC input to the MultiPlus-II. This allows for the connection of consumers like a water heater, which should not be discharged from the battery.

Delivery is Configured and Tailored to the Supplied Components

The configuration options of the MultiPlus-II are extremely diverse, just like its applications. To ensure that the system lives up to the "Plug and Play" designation as delivered, we have already made the essential settings for you – the system is thus ready for immediate use without further configuration. If you order the option with the power meter, we will set up the system directly as an ESS.
