Applications
MicrogridsLoad shiftingRenewable self-consumptionOff-grid supplyBack-up powerEvents & filmOne complete system
Everything in one cabinet.
Battery, power conversion, control and protection arrive as one engineered unit: place it, connect it, power up.
LiFePO₄ battery
33 kWh rated capacity at 90% depth of discharge on a 550–950 V DC bus.
Transformerless inverter
98% PV-to-AC efficiency with 120% overload for 10 minutes and 150% for 10 seconds.
Dual-MPPT solar input
Up to 30 kW of PV across two trackers with a wide 160–950 V operating window.
Safety built in
Hot-aerosol fire suppression at cell and cabinet level inside an IP54 enclosure.
