The storage system is capable of providing emergency power and can supply the entire house with electricity in the event of a grid failure. A boost function increases the discharge rate (C rate), which is 0.5 in continuous operation, to 0.75 for a short time. This enables the storage system to absorb peak loads, such as those that occur when electronic devices are started.

Extremely flexible and easy installation

Dominik Gluba, Head of Operations Energy Storage Systems: „During the development, the focus was on our specialist partners’ desire for flexible and simple installation. This starts with the inverter compatibility, continues with the modularity and also includes the innovative module design and connector system. This allows the storage system to be installed in under 30 minutes.

VARTA.wall is compatible with various market-leading inverter brands, including the market leader SMA, which is also the launch partner of the new storage system, and Kostal. Further compatibilities are in preparation. Thanks to its modular design, the storage device is also suitable for a wide variety of system configurations. The VARTA connector system ensures that the system components do not have to be wired.

New product family for energy self-sufficient living

In the coming months, VARTA will be launching further devices and services for energy self-sufficient living. This will include a wall box and a separate electricity tariff. The company is thus establishing itself as a partner for all households that are promoting their own energy transition.

High efficiency and standby power compatibility

The new Steca hybrid inverter has a maximum efficiency of over 98 percent and outstanding partial load operation capability. Two MPP trackers enable flexible system design.

In combination with the optional StecaGrid switch, the device can shut off a home from the grid if there is a power failure and convert to standby power mode. This system solution ensures that the hybrid inverter supplies all three phases in the home grid, making it possible to continue to use all end devices without any problem.

Clever overall concept

With its passive cooling, the StecaGrid Hybrid 10023_3 is designed for particularly low-maintenance, low-noise operation: thanks to the ventilator-free design, the hybrid inverter is functional without any moving parts. As a result, defects are avoided, and no cleaning work is required. There is also no noise from fans. The integrated grid and system protection simplifies installation and reduces installation costs.

With our new hybrid inverter, we are delivering the right device for modern, energy-independent homes. With its high efficiency, ability to operate using standby power and simple installation, it is a typical example of the high quality of KATEK power electronics, with which we achieved an annual turnover growth of over 30 percent last year“, Klauspeter Bader, Managing Director of KATEK Memmingen, explains.

Tesvolt to showcase new series of energy storage systems at The smarter E

PRESS RELEASE – Wittenberg, 02.05.2022:

Higher energy density and economic efficiency //

Tesvolt will present its new series of energy storage systems designed for commercial and industrial use at ees Europe in Munich, Germany. The new battery storage systems are set apart by their higher energy density and particularly high economic efficiency. The E series is Tesvolt’s response to the global shortage of chips in energy storage systems; the new systems are configured to use 80% fewer chips. This allows the manufacturer to produce its battery storage system solutions in larger batches and meet the skyrocketing demand for commercial storage systems.

Commerce looking for independent energy supply

With electricity costs so high at the moment, many commercial companies are currently struggling to survive, and they want to achieve independence with their own photovoltaic installation and energy storage system, for example. We have also seen this development reflected in the demand for our storage systems, which has increased enormously in recent weeks,“,reported Daniel Hannemann, Co-Founder and CEO of Tesvolt. „Because the E series uses fewer chips, we can produce it in much larger batches – and help more commercial operations switch to an independent power supply.

Optimised and streamlined for economic efficiency

In both purchasing and operations, the storage systems in the E series cost less than the existing A series, due in part to the fact that the new battery modules, which can store almost 70% more energy, are arranged more compactly. The E series also uses the latest-generation Samsung SDI lithium-ion cells, making it even more powerful and robust. This gives the overall system an efficiency rating of over 90 percent – significantly higher than that of conventional energy storage systems on the market.

Suitable for any application

The storage systems in the E series meet the same quality criteria as the A series, but higher energy density and an optimised design mean we can produce them in larger quantities,“, explains Simon Schandert, Co-Founder and CTO of Tesvolt. „The E series is available in different product variants too, so it offers the right battery storage system for every application.“ The storage systems in the E series shave peak loads, optimise self-consumption and supply back-up power. They function both on-grid and off-grid and are also very well suited as charging infrastructure for electric vehicles. The capacity of the new energy storage system solutions ranges from 70 kilowatt hours to several megawatt hours.

Power quality technology increases machinery lifespans

The quality of the electricity is another thing that’s important to many commercial and industrial operations, because it improves machines’ durability. That’s why we’ve integrated our power quality technology in both the TS-I HV 80 E and TS-I HV 100 E. It ensures good, consistent electricity quality – giving us a genuine USP on the market“, affirmed Mr Schandert. An active grid filter stabilises voltage and frequency, all the while reducing load imbalance, reactive power and harmonics in the commercial operation’s utility grid.

Visit Tesvolt at ees Europe in Munich between 11 and 13 May 2022!

Location: booth 110 in Hall B2
