SAX Power GmbH is a German company (Erbach near Ulm) that designs and manufactures residential AC battery storage systems with integrated inverter and backup capabilities. Their product family (e. g. , SAX Power Home 5. 8 kWh and Home Plus 7. 7 kWh) outputs AC directly from the battery using an inverter-less cell-control topology, enabling simpler retrofits and new PV installations without a separate hybrid inverter. The systems use cobalt-free lithium-iron-phosphate (LFP) cells, emphasize safety (rapid cell shutdown, low fire/explosion risk), very high conversion efficiency (advertised ~99%), modular expandability, compact wall-mounted form factor, and features for black-start/backup operation and energy management. SAX positions itself toward installers and end customers, highlighting Made-in-Germany manufacturing quality and performance test recognition (HTW Berlin).
