TESVOLT partners are specially trained specialist companies that are authorised to install and maintain our storage systems. As part of a partner programme, they go through various stages and benefit from extended warranties, service access and attractive participation models.
After planning and selecting the right system, your specialist partner will take care of the installation. TESVOLT provides support with preconfigured technology, tested components and personalised assistance.
TESVOLT storage systems optimise self-consumption, reduce energy costs, increase independence from the grid and enable participation in electricity trading on energy exchanges. They can be used in PV systems, charging infrastructure, commercial or industrial applications – right up to large battery parks.
A TESVOLT storage unit stores excess solar power and makes it available exactly when you need it – even at night or when the sky is overcast. This allows you to use up to 80% of the electricity you generate yourself and reduce expensive grid purchases.
Yes. TESVOLT storage systems can be flexibly integrated into existing PV systems – this is particularly attractive if your feed-in tariff is expiring or you want more independence.
Our systems are TÜV-certified and secured with multiple redundancies – depending on the area of application, they feature active cell monitoring, extinguishing systems or even their own fire protection architecture.
Our support team is available by telephone or email – fast, friendly and solution-oriented.
Depending on the product, TESVOLT offers up to a 10-year system and capacity guarantee – for maximum investment security.
Our service partners usually respond within one working day.
We guarantee spare part availability for many years and rely on durable components with verified supply chains.
TESVOLT stands for innovation and the highest quality standards. The A-series products were discontinued because we are constantly striving to offer you the most modern and efficient solutions.
Thanks to technological progress and intensive development work, we can now present you the TESVOLT FORTON , a new generation of storage systems that is even more efficient, durable and powerful.
Our aim is to remain at the cutting edge of innovation and to offer you products that ensure the long-term value and trust you place in TESVOLT. With this further development, we are setting standards for the future of energy storage - and remain your reliable partner for advanced solutions.
The A-series systems are sold out and therefore no longer available.
We guarantee continued support for the products: Our support for the TS 48 V, TS HV 70 and TS-I HV 80 products will be available to you beyond the end of sale for the entire duration of the warranty (5-year system warranty and 10-year capacity warranty). With our support, we ensure that you have a smooth transition phase if you want to switch to our new, high-performance products.
Yes, our service for the A-series will continue even after the order stop. Repairs are carried out under the terms of the warranty so that you can continue to utilise the full potential of your investment and long-term safety is guaranteed.
No, existing systems can no longer be extended with battery modules, as the A series and all corresponding battery modules are sold out.
Yes, this is possible for battery storage systems that are operated with our TESVOLT Energy Manager. These include the TS HV 70 and TS-I HV 80, which can be expanded in terms of energy and power using systems from our E series, or a TESVOLT FORTON system. They are then "grouped" and centrally controlled by the TESVOLT Energy Manager. Software version 3.0 is required.
