Why it stands out

True flexibility, phase by phase. Enjoy 100% unbalanced output across each phase, with up to 50% of rated power available per phase so your real-world loads get power exactly where they need it, not just where the rulebook says.

Built to grow with you. AC-couple it to retrofit an existing solar system, or scale up by paralleling up to 10 units for both on-grid and off-grid operation. Add multiple batteries in parallel and expand your storage on your terms.

Charge fast, discharge hard. With up to 350A of charging and discharging current, your battery bank refills quickly and delivers when demand spikes.

Ready for anything. Store energy from a diesel generator for true backup resilience, and program 6 separate time periods for battery charging and discharging to take full advantage of off-peak tariffs.

Engineered for peace of mind. A 48V low-voltage battery system with transformer isolation design delivers safer, more reliable performance backed by an IP65 rating for confident indoor or outdoor installation.
