Offgridtec backup kit Pytes V5a battery - Victron MultiPlus II 48/3000 inverter 3-phase 10.24 kWh, with electricity meter
Offgridtec backup kit replacement set 5.12 kWh or 10.24kWh with Pytes V5a battery - Victron Multiplus II 48/3000 3-phase, with or without power meter
The 3-phase backup systems from Offgridtec are ideal for emergency power supply or for expanding an existing solar system. The systems include lithium-ion batteries from Pytes, the matching MultiPlus-II inverters and a Cerbo GX MK2 from Victron Energyfor system monitoring. This allows you to secure your energy supply even in the event of a power failure.
With the Pytes batteries, you have a storage capacity of 5.12 kWh to 10.24 kWh to use your energy efficiently and remain self-sufficient for longer if necessary. Thanks to the UPS function, the MultiPlus remains switched on even in the event of a mains fault and takes over the supply to the connected consumers. The switchover happens so quickly (in less than 20 milliseconds) that uninterrupted operation of computers and other electronic devices can be guaranteed.

The 48 V battery charger is also very well proportioned with 70 A charging power and is supplemented by a 50 A transfer switch, which can be used to switch back and forth between the AC connections at lightning speed.
Important performance features of the Multiplus-II 48/5000/70-50:PowerControl and PowerAssist -increase of mains or generator powerbuilt-in anti-islanding function and connection option for external current sensor (optional)can be used as a backup device in grid-connected systems;can be used as a backup device in grid-connected systems for power supply in the event of grid failurescan be used in various ESS (Energy Storage System) applicationsbest suited for professional seafaring, yachts, vehicles and land-based, off-grid applicationsVE.Bus interface for parallel and three-phase operation, remote monitoring and system integrationpractically unlimited power through parallel and three-phase operationcan be configured on site or remotely using VEConfigure software
Always enough power thanks to PowerControl and PowerAssist:A maximum mains or generator current can be set on the MultiPlus-II 48/5000/70-50. The MultiPlus-II then takes other connected AC consumers into account and only uses the current that is still "available" to charge the battery. This prevents the generator or mains connection from being overloaded (PowerControl function). The PowerAssist function adds a new dimension to the PowerControl principle. Load peaks often only occur for a limited period of time. In such cases, the MultiPlus-II immediately compensates for insufficient generator, shore power or mains power with energy from the battery. If the load is reduced, i.e. consumers are switched off, the available energy can then be used to charge the batteries again.
Maximum flexibility thanks to two AC outputs:The main output ensures uninterrupted operation. In the event of a mains failure or an interruption in the shore/generator power, the MultiPlus-II takes over the supply to the connected loads. The switchover takes place so quickly (in less than 20 milliseconds) that uninterrupted operation of computers and other electronic devices is guaranteed. The second output only supplies power if alternating current is available at the input of the MultiPlus-II. Consumers that are not allowed to discharge the battery, such as a water heater, can be connected to this output.
Remote configuration and monitoring:Install a Color Control GX or other GX products to connect to the Internet. The operating data can be saved and viewed free of charge on our VRM (Victron Remote Management) website. If systems are connected to the Internet, they can be accessed remotely and settings can be changed.
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, we can do this for you for an additional charge. To do this, place the "Offgridtec pre-configuration" item linked above in the shopping cart during the ordering process. In this case, shipping may take 3-5 working days longer until the configuration has been carried out.
