TESVOLT energy storage system

Storage systems TESVOLT — these are professional and flexible modular solutions for any situation. Various configurations are available through 4.8 kW·h for indoor and outdoor installation. TESVOLT batteries allow operation in both stand-alone and grid-connected power supply systems.

Storage systems TESVOLT provide uninterrupted power supplies for private homes, hospitals and data centers, smooth consumption peaks, allow the creation of an autonomous network, or increased own solar power consumption.

TESVOLT uses extremely safe and environmentally friendly nickel-manganese-cobalt-oxide based technology, enclosed in 14 prismatic cells with such high-quality as those that have been employed in electric cars so far.

Battery module TESVOLT based on high-grade prismatic cells Samsung SDI

The unique Active Battery Optimizer (ABO) — battery balance managment provides detecting differences in battery systems and correct them on a continuous basis. This process significantly increases the lifespan of individual cells up to 30 years and 8,000 cycles. Charging and discharging current on long-term basis is 1C and even at 4C for short periods (max. 20 seconds).

Cell monitoring TESVOLT

Controlled distribution of energy across individual cells and in every module

Cells Samsung SDI do not contain environmentally harmful heavy metals and can be completely recycled at the end of their service life. TESVOLT offers a take-back scheme for their batteries at no additional cost for customers.
