Connection & Installation
The VoltStorage SMART can be installed in an ambient temperature of
0° – 35°, so the storage system should be placed inside your house.
To shorten the installation time, we recommend installing the power
storage near your fuse box (up to 5 meters away).
It should also be noted that the VoltStorage SMARTis designed for
floor mounting and must therefore be placed on firm ground.
To guarantee full compatibility of the VoltStorage SMART power
storage with all photovoltaic systems, we rely on an AC-coupled
system. AC systems are designed in such a way that self-produced
solar power is first converted into alternating current in the
photovoltaic inverter, so that it can be used directly by the
household.
In order to store surplus solar power not used by the household, a
conversion from alternating to direct current is necessary. This
conversion is carried out by an integrated battery inverter which
has been specifically optimized for home storages based on vanadium
redox flow technology. Our VoltStorage Smart is therefore
compatible with all photovoltaic systems.
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.
After successful installation, the VoltStorage SMART power storage
device must be connected to the Internet via WiFi or Ethernet cable
in order to regularly receive automatic software updates that
continuously optimize the charging and discharging logic of the
storage system and further increase the efficiency of the overall
system.
In addition, the battery storage needs to be connected to the
Internet in order to access current and past data about your power
storage, your photovoltaic system and your power consumption via
the VoltStorage App.
Operating Options
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.
Storage System
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.
In theory, the proven vanadium redox flow storage technology
enables decoupling performance and capacity, which is why the
capacity can be increased by increasing the amount of liquid
regardless of performance. In practice, however, mechanical
challenges arise that significantly increase the additional costs
for a freely scalable capacity.
However, our goal is to offer cost-efficient storage systems, which
is why we deliberately renounce a free configuration of the storage
capacity.
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.
With our VoltStorage App you can access current and past data about
your VoltStorage SMART battery, your photovoltaic system and the
power consumption of your household. You will receive the access
data to the VoltStorage App from us in time before the installation
date.
The VoltStorage App can be accessed via any web browser via PC,
tablet and smartphone and can be downloaded as Android and iOS App
in the respective App Stores from autumn 2018 onwoards.
Purchase & Costs
The complete offers provided by us or our partners already
include include 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. You can request a complete offer without obligation
from our support
team.
The VoltStorage SMART battery system is 100% maintenance-free.
Thanks to its Internet connection, the VoltStorage SMART can
regularly receive software updates that optimize the loading and
unloading logic of the storage system and further increase the
efficiency of the overall system.
In addition, the VoltStorage SMART has an electrolyte rebalancing
system that automatically adds additives to the electrolyte liquid
through sensor control, thus keeping the quality of the vanadium
electrolyte constantly high. For this reason there is no
maintenance work on the VoltStorage SMART.
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.
