Frequently asked questions
What is the Varta.wall 18?
The Varta.wall 18 is a high-voltage battery storage system with 18.0 kWh usable capacity based on lithium iron phosphate (LFP) cells. It consists of a Master Unit with a base and four BM2 storage modules and stores surplus solar power for later self-consumption.
Which systems is the Varta.wall 18 suitable for?
As a high-voltage storage system with a nominal voltage of 358.4 V DC and a charging and discharging current of 26.0 A each, it is suitable for photovoltaic systems with hybrid inverters that support high-voltage battery coupling. The modular design allows for 1 to 4 battery modules.
Can the capacity be expanded later?
Yes. The system has a modular design and can be scaled with 1 to 4 BM2 battery modules in combination with the BMS BM1/BM2. The expansion stage supplied here includes four modules with a total of 18.0 kWh usable capacity.
Is the Varta.wall 18 suitable for cool locations?
The storage system operates with passive cooling and can be used from -10 °C ambient temperature. With protection class IP55, it is protected against dust and jet water and can therefore also be operated in unheated technical rooms.
Who is Varta?
Varta is an established manufacturer of battery and storage technology with a long tradition in energy storage. The home storage systems of the series are manufactured in Germany and are aimed at private self-consumption of solar power.
Where can I buy a battery storage system in Austria?
The Varta.wall 18 and other PV accessories are available from SOLARVIC via solarvic.at. The storage system is shipped by freight forwarding.
How can I order?
Directly online via solarvic.at - the SOLARVIC team will be happy to help with any questions regarding the design.
