Offgridtec Backup kit retrofit kit 20.5kWh with Pytes 48100r-c battery Victron MultiPlus-II 48/5000 3-phase

The 3-phase backup systems from Offgridtec are ideal for emergency power supply or for expanding an existing solar system. The systems contain lithium-ion batteries from Pytes the matching MultiPlus-II inverters and a Cerbo GX MK2 from Victron Energy for system monitoring. This allows you to secure your energy supply even in the event of a power failure.

With the batteries from Pytes, you have a storage capacity of 20.5 kwh to 30.7 kwh, depending on your choice, to use your energy efficiently and remain self-sufficient for longer if required. Thanks to the UPS function, the MultiPlus remains switched on even in the event of a mains failure 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.

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

Extended use of your backup system

The backup kit is supplied either with or without Victron electricity meter and cable, although an energy meter is always required to set up an energy storage system.

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 a pre-configuration, the meter must be purchased in advance or for the system!
