To operate the TESVOLT FORTON in combination with a photovoltaic system and with the goal of maximizing self-consumption, we now offer our commercial and industrial storage system with the SMA SI-X inverter, available with 30 or 50 kW output.

A true economic miracle: We've made the standard version of the TESVOLT FORTON - designed for flexibility marketing and TESVOLT ENERGY Trading with the KACO inverter—even more attractively priced.

As part of the TESVOLT Energy Manager's licensing model, we've simplified the commissioning process and eliminated the monthly fees.

Are you interested in self-consumption optimization?

Then you should take a closer look at our TESVOLT FORTON with the SMA SI-X inverter. With significantly lower output of 30 or 50 kW compared to the KACO inverter, the likelihood of remaining in the low-voltage range according to VDE-AR-N 4105 + NELEV in combination with a photovoltaic system increases.

For total system capacities under 270 kW, no plant certificate or EZA controller is required. In addition, shorter approval processes can be expected, along with an overall higher likelihood of approval—since many distribution grid operators significantly delay or even deny grid connection requests for systems over 270 kW in the medium-voltage range.

So get in touch with a TESVOLT sales representative today to receive delivery times, technical specifications, a price indication, and—if needed—support with the grid connection!

Are you interested in the highly profitable application of energy trading?

Then you should take a closer look at the TESVOLT FORTON with the KACO inverter. With high output and a wide range of configuration options, this variant can be used in both low-voltage and medium-voltage grids, depending on the grid access requirements.

Thanks to high-yield arbitrage trading, the TESVOLT FORTON can primarily be connected to the grid as a stand-alone application with its own metering concept—without being linked to a PV system. Exclusively for the TESVOLT ENERGY application, we can extend the performance warranty to 15 years and have also further optimized the pricing.
