Three-phase AC coupler SoWave Three Phase Series

THREE-PHASE STORAGE FROM 8 TO 12 KW FOR SG SERIES MICROINVERTER SYSTEMS

Rated Power: 8, 10 or 12 kVA
Charge and Discharge: Up to 260 A
Protection Rating: IP65
Max Efficiency: 97.5%

Storage for microinverters already in place
The coupler connects on the AC side to an existing three-phase SG series microinverter system and adds a battery, without touching the panels.
Off-grid operation
Its grid-forming function keeps SG series microinverters producing off-grid, with a pure sine wave three-phase output.
Dynamic phase balancing
Current on the three phases is rebalanced continuously. Short-term overload capacity of up to 6 HP for motor starts.
Smart energy management
Built-in energy and battery management system, several storage modes to choose from, 51.2 V lithium-ion or lead-acid batteries.
