Offgridtec Backup Kit 5.12kWh Pytes V5a Battery - Victron MultiPlus II 48/3000 Inverter 1-Phase

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

With Pytes batteries, you have a storage capacity ranging from 5.12 kWh to 10.24 kWh, allowing you to use your energy efficiently and remain self-sufficient for longer when needed. Thanks to the UPS function, the MultiPlus remains powered on even during a grid failure and continues to supply power to 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?

• Pytes V5a LiFePO4 battery, 5.12 kWh, 51.2 V, 100 Ah (1 or 2 units, depending on selection)
• 1x Victron MultiPlus-II 48/3000/35-32 230V
• 1x Victron Lynx Distributor (M10)
• 1x Victron Cerbo GX MK2 communication hub for system monitoring
• 1x Victron GX Touch 50 display panel for Cerbo GX
• 1x 3m Victron RJ45 UTP cable
• 1x Offgridtec 5-pack MEGA fuse 125A 70V for 48V systems
• 1x Pytes data cable from battery to Victron GX, 3.5 m
• 1x Pytes battery connection cable set V5a, 2 m, M10, 50 mm² to Amphenol 8 mm
• 1x Offgridtec® 2m battery cable, 35mm², with M8 eyelets on both ends

If selecting a power meter

• 1x Victron VM-3P75CT Energy Meter
• 1x Victron 5m RJ45 UTP cable

Expanded Use of Your Backup System

The backup kit is available with or without the Victron energy meter and cable; however, an energy meter is required for setting up an energy storage system.

With this electricity meter, you can set up a grid-tied installation and then monitor your energy consumption and keep track of your energy costs. Thanks to phase compensation, you can even use the 3-phase meter for 1-phase systems. This makes seamless integration of decentralized energy sources and consumers into the existing power grid a breeze.

The Electronic Core – the Victron Multiplus-II Combination Unit

The Multiplus-II is a high-end unit 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 range of applications to include energy storage systems. The Multiplus is therefore ideal for use as a backup power supply in both grid-connected and off-grid systems.
