SAX Power releases 5.8 kWh residential AC battery

Germany-based SAX Power has introduced a new AC 5.8 kWh battery with an integrated inverter function for residential use.

The SAX Power Home system uses a lithium iron phosphate battery (LiFePO4) and can be expanded to up to 17.3 kWh by connecting up to three modules.

“The heart of the specially developed SAX technology is the intelligent, digital control of the battery cells, which converts direct current directly into alternating current,” the company said in a statement. “This eliminates the need for the complex installation of a hybrid inverter, which is necessary for all previous home storage systems between the battery and the house power grid.”

The battery measures 530 mm × 530 mm × 250 mm and has a weight of 55 kg. The new product can reportedly handle temperatures of 5 C to 35 C and a maximum humidity of 90%. The integrated inverter has a conversion efficiency of 99%.

SAX Power guarantees a battery capacity of 80% after 10 years.

“The SAX Power Home storage units are pure AC storage units and are therefore very suitable for PV systems,” the company added. “SAX Power already has a network of service partners in Germany, Poland, Austria, and Switzerland, which is constantly being expanded.”
