Offgridtec Backup Kit 3-phase 28.8kWh with Pylontech US5000 battery Victron MultiPlus-II 48/8000

The backup systems from Offgridtec are ideal for emergency power supply or for expanding an existing solar system. In addition to lithium-ion batteries from Pylontecha suitable MultiPlus-II inverter and a Cerbo gx for system monitoring. This allows you to secure your energy supply even in the event of a power failure.

Thanks to the UPS function, the MultiPlus remains switched on even in the event of a power failure and takes over the supply to the connected loads. The switchover happens so quickly (in less than 20 milliseconds) that uninterrupted operation of computers and other electronic devices can be guaranteed.

Areas of application for the Offgridtec backup kit:

• Emergency power supply
• Off-grid solar systems (stand-alone systems)
• Retrofitting existing PV systems
• Grid-connected power supply
• UPS systems

what does the Offgridtec backup system contain?

• Pylontech us5000c 3.5kwh LiFePO4 battery (depending on selection 4x, 6x or 8x)
• 3x MultiPlus-II 48/8000/110-100/100 230v appliance combination
• 2x Victron Lynx Distributor
• 1x Victron Cerbo gx control panel
• 1x Victron gx Touch 50 display panel for Cerbo gx
• 1x Victron mk3-usb Ve.Bus to usb Interface
• 1x 1.8m VE.Can to Can-Bus bms type A cable
• 2x 0.9m Victron rj45 utp cable
• 1x 3m Victron rj45 utp cable
• 6x 1m Offgridtec Battery cable 35mm² M8 eyelets
• 6x 200A 70v mega fuse
• 2x Pylontech Battery connection cable set

Extended use of your backup system

In order to set up an ess (Energy Storage System) with the backup system, an energy meter with connection cable is required:

• Victron vm-3p75ct Energy Meter 3-phase electricity meter 75A/phase
• 5m Victron rj45 utp cable

With this electricity meter, you can carry out a grid-parallel installation and then monitor your energy consumption and control your energy costs. Thanks to phase compensation, you can even use the 3-phase meter for 1-phase systems. This means that seamless integration of decentralized energy sources and consumers into the existing power grid is no problem.

In order for an ess to be included in the pre-configuration, the meter must be purchased in advance or for the system!

The storage solution - Pylontech us5000c batteries

The us3000c storage system is a lithium battery of the latest generation. It has been specially designed to meet the high demands placed on backup storage systems. Thanks to state-of-the-art technology, maximum safety and a long service life are guaranteed, even with regular deep discharges.

• Extremely cycle-resistant - over 6000 cycles at 95% DoD
• Absolutely intrinsically safe lithium technology
• High charging and discharging capacity possible
• Integrated bms
• Very high storage density - low weight and compact design
• Absolutely maintenance-free and durable
• Pre-charge function to protect the ess system from overvoltage

The electronic core - the Victron Multiplus-II device combination

The Multiplus-II is a high-end device combination from Victron Energy, consisting of a 48 V battery charger, inverter and transfer switch. This combination combines the classic Multiplus components with an external current sensor and integrated anti-island function. This expands the PowerControl and PowerAssist functions to 50a and extends the potential range of use to energy storage system applications. The Multiplus is therefore ideal for use as a backup device in grid-connected and off-grid power supply systems.

• 8000 w power with non-linear load 6400 w continuous load and 15000 w peak power
• for 48v battery voltage
• 100A transfer switch
• 110A battery charger
• Output voltage: 230 vac, frequency: 50 Hz
• max. efficiency: 95
• Protection class: IP22

Configuration

The MultiPlus-II is delivered unconfigured as standard. You can find the configuration instructions for the system here in the download area. If you would like us to pre-configure the system for you, we can do this for you for an additional charge. To do this, place the article linked above "Offgridtec Pre-configuration" in the shopping cart during the ordering process. In this case, shipping may take 3-5 working days longer until the configuration has been completed.

System monitoring with the Victron Cerbo gx and gx Toch display

With the Cerbo gx communication center, you can easily control and monitor your system. The flexible connection options maximize your system performance. Thanks to the Cerbo gx, you can control your system from anywhere. With the gx Touch 50 display, you always have an overview of all your system parameters and can make changes quickly and easily.

Safety note: Only have this complete system installed and commissioned by a qualified electrician.
