The backup systems from Offgridtec are ideally suited for emergency power supply or for expanding an existing solar system. The systems include Lithium-Ion batteries from Pylontech, a compatible MultiPlus-II inverter, and a Cerbo GX MK2 for system monitoring from Victron Energy. This ensures that you can maintain your energy supply even in the event of a power outage.
Thanks to the UPS function, the MultiPlus remains operational even during a grid failure and takes over the supply of connected devices. The switchover occurs so quickly (in less than 20 milliseconds) that uninterrupted operation of computers and other electronic devices is guaranteed.
Application Areas of the Offgridtec Backup Kit:
- Emergency power supply
- Grid-independent solar systems (island systems)
- Retrofit for existing PV installations
- Grid-tied power supply
- Uninterruptible power supply (UPS) systems

The MultiPlus device combination is pre-configured to be compatible with the Pylontech batteries.
Extended Use of Your Backup System
To establish an ESS (Energy Storage System) with the backup system, an energy meter with connection cable is required:
With this power meter, you can set up a grid-parallel installation and subsequently monitor your energy consumption or control your energy costs. Thanks to phase compensation, you can also operate the 3-phase meter for single-phase systems. This facilitates seamless integration of decentralized energy sources and consumers into the existing power grid.
For an ESS to be considered in the pre-configuration, the meter must be purchased in advance or along with the system!
The Storage Solution – Pylontech US5000 Batteries
The Pylontech US5000 storage is a next-generation Lithium battery. It has been designed to meet the high demands placed on backup storage. With state-of-the-art technology, the highest safety and a long lifespan, even with regular deep discharges, are guaranteed.

- Completely safe Lithium technology
- High charge and discharge performance possible
- Integrated BMS
- Very high storage density – lightweight and compact design
- Completely maintenance-free and durable
- Pre-charge function to protect the ESS system from over-voltage
The Electronic Core – The Victron MultiPlus-II Device Combination
The MultiPlus-II is a high-end device combination from Victron Energy, comprising a 48V battery charger, inverter, and transfer switch. This combination integrates the classic MultiPlus components with an external current sensor and an integrated anti-island function. This extends the functions PowerControl and PowerAssist to 50A and broadens the potential application area to energy storage system applications. Therefore, the MultiPlus is ideally used as a backup device in grid-tied and standalone systems for power supply.
