Offgridtec’s backup systems are ideal for emergency power supply or for expanding an existing solar system. In addition to lithium-ion batteries from Pylontech, the systems include a compatible MultiPlus-II inverter and a Cerbo GX MK2 from Victron Energy for system monitoring. This allows you to ensure your power supply even in the event of a power outage.

Thanks to the UPS function, the MultiPlus remains powered on even during a grid failure and takes over powering the connected loads. The switchover occurs so quickly (in less than 20 milliseconds) that uninterrupted operation of computers and other electronic devices is guaranteed.

Applications of the Offgridtec Backup Kit:

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

What does the Offgridtec backup system include?

The Multiplus device combination is preconfigured to be compatible with Pylontech batteries.

Expanded use of your backup system

To set up an ESS (Energy Storage System) with the backup system, one energy meter with a connection cable is required:

With this energy meter, you can perform 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 1-phase systems. This ensures seamless integration of decentralized energy sources and consumers into the existing power grid.

To ensure an ESS can be included in the pre-configuration, the meter must be purchased in advance or as part of the system!

The Storage Solution – Pylontech US5000 Batteries

The Pylontech US5000 storage unit is a latest-generation lithium battery. It was specifically designed to meet the high demands placed on backup storage. Thanks to state-of-the-art technology, maximum safety and a long service life are guaranteed even with regular deep discharges.

  • Extremely cycle-stable – over 6,000 cycles at 95% DoD
  • Absolutely intrinsically safe lithium technology
  • High charge and discharge performance possible
  • Integrated BMS
  • Very high energy density – lightweight and compact design
  • Completely maintenance-free and long-lasting
  • 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 48V battery charger, inverter, and transfer switch. This combination integrates the classic Multiplus components with an external current sensor and built-in anti-islanding function. This extends the PowerControl and PowerAssist functions to 50A and broadens the potential application range to include energy storage system applications. The Multiplus is therefore ideal for use as a backup device in both grid-connected and off-grid power supply systems.

  • 10,000W power under non-linear load – 8,000W continuous load – 18,000W peak power
  • for 48V battery voltage
  • 100A transfer switch
  • 140A battery charger
  • Output voltage: 230 VAC, frequency: 50 Hz
  • Max. efficiency: 95%
  • Protection class: IP22

System monitoring with the Victron Cerbo GX and GX Touch Display

With the Cerbo GX MK2 control center, you can easily control and monitor your system. The flexible connection options maximize your system performance. Thanks to the Cerbo GX MK2, you can control your system from anywhere. With the GX Touch 50 display, you always have all your system parameters at a glance and can make changes quickly and easily.
