Offgridtec Backup kit 3-phase 4.8kWh with Pylontech us2000c battery Victron MultiPlus ii 48/3000

The backup systems from Offgridtec are ideal for emergency power supply or for expanding an existing solar system. The systems include lithium-ion batteries from Pylontech, a suitable 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 active even during a grid failure and takes over the supply for connected devices. The switch-over occurs so quickly (in less than 20 milliseconds) that uninterrupted operation of computers and other electronic devices is guaranteed.

Areas of Application for the Offgridtec Backup Kit:

• Emergency power supply
• Off-grid solar systems (island systems)
• Retrofit for existing PV systems
• Grid-connected power supply
• UPS systems

What is included in the 3-phase Offgridtec Backup System?

• Pylontech US2000C 2.4kWh LiFePO4 battery (depending on selection, 2x or 4x)
• 3x Victron MultiPlus-II 48/3000/35-32 230V device combination
• 2x Victron Lynx Distributor
• 1x Victron Cerbo GX MK2 control panel
• 1x Victron GX Touch 50 display panel for Cerbo GX
• 1x Victron MK3-USB Ve.Bus to USB interface
• 1x 1.8m VE.Can to CAN Bus BMS Type A cable
• 2x 0.9m Victron RJ45 UTP cable
• 1x 3m Victron RJ45 UTP cable
• 3x 1m Offgridtec battery cable 35mm² M8 lugs
• 3x 125A 70V MEGA fuse
• Pylontech battery connection cable set (depending on selection, 1x or 2x)

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:

• Victron VM-3P75CT Energy Meter 3-phase meter 75A/phase
• 5m Victron RJ45 UTP cable

With this energy meter, you can install a grid-parallel setup and then monitor your energy consumption or control your energy costs. Thanks to phase compensation, you could even use the 3-phase meter for single-phase systems. This allows for seamless integrations of decentralized energy sources and consumers into the existing power grid.

To ensure an ESS is considered in the pre-configuration, the meter must be purchased beforehand or with the system!

The Storage Solution – Pylontech US2000C Batteries

The US2000C storage is a lithium battery of the latest generation. It has been specifically designed to meet the high demands placed on backup storage systems. Thanks to state-of-the-art technology, maximum safety and long service life are guaranteed even with regular deep discharge.

• Extremely cycle-resistant – over 6000 cycles at 95% DoD
• Absolutely safe lithium technology
• High charge and discharge capacity
• Integrated BMS
• Very high storage density – low weight and compact design
• Completely maintenance-free and durable
• Pre-charge function to protect the ESS system from over-voltage

The Electronics 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 links the classic MultiPlus components with an external current sensor and integrated anti-island function. As a result, the PowerControl and PowerAssist features are expanded to 50A, extending the potential application scope to energy storage system applications. Therefore, the MultiPlus can ideally serve as a backup device in both grid-connected and off-grid systems for power supply.

• 3000W power with non-linear load – 2400W continuous load – 6000W peak power
• for 48V battery voltage
• 32A transfer switch
• 35A battery charger
• Output voltage: 230 VAC, frequency: 50 Hz
• Maximum efficiency: 95%
• Protection class: IP22

Configuration

The MultiPlus-II is delivered unconfigured by default. You will find the configuration instructions for the system in the download area. If you wish for a pre-configuration by us, we can gladly undertake this for an additional charge. To do this, add the linked item "Offgridtec Pre-configuration" to your cart during checkout. In this case, shipping may take 3-5 business days longer until the configuration is completed.

System Monitoring with the Victron Cerbo GX MK2 and GX Touch Display

With the Cerbo GX MK2 communication hub, you can easily control and monitor your system. The flexible connection possibilities maximize your system performance. The control of your system is made possible from anywhere thanks to the Cerbo GX MK2. With the GX Touch 50 display, you can keep all parameters of your system in view and make changes quickly and easily.

Safety Notice: Have this complete system installed and put into operation only by a qualified electrician.
