With the SigenStack, Sigenergy is setting new standards for modular commercial storage systems. The concept, which can be set up both indoors and outdoors, consists of a hybrid inverter and several towers of stackable storage modules. The maximum weight of the individual system components is 105 kg. This can be implemented efficiently thanks to the low effort required for installation. With 11.7 kWh of usable capacity per battery and 4 to 21 units in the system, a total of up to 246 kWh is possible. The power classes of the inverters range from 50 to 125 kW. They are also available in two versions, with and without a backup function. A comprehensive package of protective functions and interfaces leaves little to be desired. Larger systems up to the MW range can also be implemented when connected in parallel.
