Frequently asked questions (FAQs)
Here you will find answers to your questions about VoltStorage.
Connection & Installation
To ensure full compatibility of the VoltStorage Smart power storage with all photovoltaic systems, we rely on an AC-guided system. Our VoltStorage SMART is therefore compatible with both single-phase and multi-phase photovoltaic systems.
As long as the power-to-heat system or heat pump does not run via its own meters, the system can be coupled to the power storage and operated through it.
Electric vehicles can be charged via the VoltStorage SMART. Depending on the size of the storage system or the number of SMART power storage units installed and the amount of solar power stored, e-vehicles can be charged for small to medium driving distances, provided that a large proportion of the total capacity is used.
The overall efficiency of energy storage systems depends on the area of use and the power that is drawn. Our storage system is optimized for use as a solar power storage device and for an output range of up to 800 watts which covers most of the power requirements of a household. This enables us to achieve overall efficiencies of over 80%.
The weight of the storage system without electrolyte liquid is 60 kg. After filling the two electrolyte tanks, the total weight of the VoltStorage SMART is 362 kg. For this reason, the 220 litre vanadium electrolyte is only filled into the liquid tanks by a specialist installer after the VoltStorage SMART has been completely set up.
Any number of VoltStorage SMART battery systems can be connected in series within a multi-storage system. This way you can easily increase the performance and capacity of your power storage system and adapt it even better to the power requirements of your household.
Purchase & Costs
The total cost of the VoltStorage SMART home battery is 6,999 Euro incl. VAT. This includes all costs for delivery, professional installation, integrated battery inverter, automatic software updates and use of the VoltStorage App. There are no additional costs for you.
The VoltStorage Smart can currently only be ordered and delivered in Germany. However, we are already working on being able to offer our storage system in other countries in the near future.
We at VoltStorage specialise exclusively in the manufacturing energy storage systems. When planning to install a PV system, it is therefore best to contact the solar engineer of your choice. Since our VoltStorage SMART power storage is compatible with all photovoltaic systems, our system can be connected to any PV system.
Concerning the configuration of the power storage system, you are welcome to contact our customer service directly. We will be happy to help you at any time.
Starting from a PV output of 2-3 kWp the purchase of a VoltStorage SMART battery storage device can boost your solar power consumption and thus lead to an increase in the degree of self-sufficiency.
