In order to accurately calculate power storage costs per kWh, the entire storage system, i.e. the battery and battery inverter, is taken into account. The key parameters here are the discharge depth [DOD], system efficiency [%] and energy content [rated capacity in kWh].
Storage systems for commercial use are charged and discharged more frequently than those in individual homes, and must therefore be able to withstand higher cycle loads. TESVOLT TS HV systems for commercial applications can complete a full charge and discharge cycle within just one hour (1 C-rate), which helps to optimise the self-consumption of factories, for example. As a result, more cycles can be achieved per year than with the conventional storage systems found in private homes. And commercial storage systems are also equipped to deal with high cycle loads during peak shaving, when providing balancing power and in off-grid applications.
