Power is good, performance is better

An outstanding battery storage system is more than the sum of its parts

The performance, durability and safety of the overall system depend on each individual battery cell. That is why, at TESVOLT, we only use top-quality components – such as the high-efficiency prismatic cells manufactured by our partner Samsung SDI. And we have also developed a battery management system that does away with the typical problems found in lithium-ion batteries. The TESVOLT Active Battery Optimizer (ABO) monitors the charging and discharging of each and every cell. This helps us create safe, high-performance, battery systems with long lifespans and an efficiency rating of up to 98%. Put these features together and you can see why TESVOLT storage systems are among the most advanced products available today. No need to take our word for it — we have won a multitude of awards that prove that experts share our view, such as the Hugo Junkers Award, the smarter E AWARD and the German Entrepreneur Award.

Future-proof

Thanks to revolutionary ABO battery management technology, the battery modules in TESVOLT storage systems can be upgraded or exchanged, with no problems or loss of efficiency even after years of operation.

Maximum safety

The prismatic battery cells used by TESVOLT will not ignite even if punctured by a metal spike. And in the rare event of a fault, you can rely on the ABO battery management system to detect it early on.

Maximum cost efficiency

The batteries used in TESVOLT storage systems boast an efficiency rating of up to 98%, and a round-trip efficiency, including the battery inverter, of up to 94%, with self-consumption of just 5 W. The long lifespans and impressive cycle stability of TESVOLT storage systems makes them especially cost efficient.

Maximum lifespan

The intelligent ABO battery management technology ensures that each battery cell is always optimally charged and discharged. In combination with the premium battery cells used in TESVOLT storage systems, this gives them a lifespan of 30 years or 8,000 cycles.

Strong partners

TESVOLT works with strong partners to deliver excellence. We source our cells through close collaboration with Samsung SDI, and our partner for external system components is SMA, the German market leader for inverters.

Uncompromisingly high performance

The ABO battery management technology and premium-quality battery cells enable fast charging and discharging. With a discharge rate of 1C, our storage systems are suitable for professional use in agriculture, commercial operations and industry.

Active Battery Optimizer – ABO 2.0

In addition to the cells, every battery module comprises an Active Battery Optimizer, which monitors and controls the charging and discharging of each individual cell.

BatMon battery monitoring: transparency down to the very last cell

Every TESVOLT storage system can be seamlessly monitored using the BatMon software, which provides a visual depiction of the health of overall system, all its battery modules and even each individual cell. This means you can check up on your system at any time and make sure that it is working reliably. Our software shows the voltage, state of health (SoH) and state of charge (SoC) of each individual cell.

And in the unlikely case that any anomalies or defects do occur, they are quickly identified and rectified. Thanks to the TESVOLT ABO, you can exchange battery modules with no loss of efficiency even after years of operation.

Active Power Unit – APU

The Active Power Unit contributes to battery management and allows communication with other system units while monitoring the safety of the battery system.
