The backup systems from Votimax.de 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 suitable MultiPlus-II inverter and a Cerbo GX from Victron Energy for system monitoring. This allows you to secure your energy supply even in the event of a power failure.

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 loads. 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 Voltimax.de backup kit:

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

The storage solution - Pylontech US3000C batteries

The US3000C storage battery is a lithium battery of the latest generation. It has been specially designed to meet the high demands placed on backup storage systems. Thanks to state-of-the-art technology, maximum safety and a long service life are guaranteed even with regular deep discharges.

• Extremely cycle-resistant - over 6000 cycles at 95% DoD
• Absolutely intrinsically safe lithium technology
• High charging and discharging capacity possible
• Integrated BMS
• Very high storage density - low weight and compact design
• Absolutely maintenance-free and durable
• Pre-charging function to protect the ESS system against overvoltage function

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 combines the classic Multiplus components with an external current sensor and integrated anti-island function. This expands the PowerControl and PowerAssist functions to 50A and extends the potential range of use to energy storage system applications. The Multiplus is therefore ideal for use as a backup device in grid-connected and off-grid power supply systems.

• 5000W power with non-linear load - 4000W continuous load - 9000W peak power
• for 48V battery voltage
• 50A transfer switch
• 70A battery charger
• Output voltage: 230 VAC, frequency: 50 Hz
• max. efficiency: 95
• Protection class: IP22

System monitoring with the Victron Cerbo GX and GX Toch display
With the Cerbo GX communication center you can easily control and monitor your system. The flexible connection options maximize your system performance. Thanks to the Cerbo GX, you can control your system from anywhere. With the GX Touch 50 display, you always have an overview of all your system parameters and can make changes quickly and easily.
