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.
