Offgridtec Backup Kit Retrofit Kit 20.5kWh With Pytes 48100R-C Battery Victron MultiPlus-II 48/5000 3-Phase

3-Phase Backup System for Backup Power Supply

The 3-phase backup systems are the perfect solution for backup power supply or for the expansion of existing solar systems. They consist of high-quality lithium-ion batteries from Pytes, flexible MultiPlus-II inverters, and a Cerbo GX MK2 communication center from Victron Energy for system monitoring. This way, you are well equipped to ensure your energy supply even in the event of a power outage.

Efficient Energy Storage

The batteries from Pytes offer a storage capacity of 20.5 kWh to 30.7 kWh depending on selection, ideal for efficient energy use and maximum self-sufficiency. The integrated UPS function ensures that the MultiPlus remains active even in case of grid failures and supplies the connected devices. The switchover takes place in less than 20 milliseconds, so that computer systems and other electronic devices can be operated without interruption.

Areas of Application of the Backup System

• Backup Power Supply
• Grid-independent Solar Systems (Off-grid Systems)
• Retrofitting of Existing PV Systems
• Grid-connected Power Supply
• UPS Systems

Extended Use of Your Backup System

The backup kit can optionally be supplied with or without Victron energy meter and cable. To build an Energy Storage System (ESS), an energy meter is required. With this meter, you can perform a grid-parallel installation and monitor your energy consumption as well as energy costs. Thanks to phase compensation, the 3-phase meter is also suitable for 1-phase systems, which enables easy integration of decentralized energy sources.
