AC Battery

The Solar­na­tive AC Bat­tery will be avail­able with 0.9 kWh or 1.8 kWh capac­i­ty (ACB‑0.9 and ACB‑1.8). Based on our pro­pri­etary high-fre­quen­cy tech­nol­o­gy, the AC Bat­tery is using a unique sin­gle-cell tech­nol­o­gy — each bat­tery cell is con­trolled indi­vid­u­al­ly by an inte­grat­ed bidi­rec­tion­al invert­er. With this approach, there is no dan­ger of cell mis­match­es and over­heat­ing. Each cell is always oper­at­ed in its opti­mum work­ing con­di­tion lead­ing to unprece­dent­ed safe­ty and lifetime.

Var­i­ous ACBs can be com­bined in 1‑phase or 3‑phase sys­tems con­trolled by a Bat­tery Con­trol Unit (BCU) via pow­er line com­mu­ni­ca­tion. The BCU is inte­grat­ed in the Smart Ener­gy Home sys­tem via LoRa.

The sys­tem is grid-form­ing and pro­vides true 3‑phase back-up func­tion­al­i­ty, so that the Smart Ener­gy Home can be oper­at­ed as an off-grid sys­tem as well.

With its mod­u­lar approach the AC bat­tery sys­tems fea­tures a superb charg­ing / dis­charg­ing effi­cien­cy over a wide pow­er range. Even low base con­sump­tion of 100 W dur­ing the night is pro­vid­ed at max­i­mum dis­charg­ing efficiency.

With the flex­i­ble con­fig­u­ra­tion and spa­tial arrange­ment, the sys­tem fits into every cor­ner and every niche.
