[ACB-PB] AC Board - Polyphase Backup Board AC Board - Polyphase Backup Board 2.webp
Commercial AC Boards
AC Board - Polyphase Backup Board
Login to see price
Designed for 3 phase connections and single phase inverters. While off-grid the board will combine all 3 phases into one so the system can act as a 'single phase' system, feeding loads across the original 3 phases.
When the grid comes back up, the board will first un-combine the 3 phases, then reconnect each phase, as a 3 phase system, back to the grid.
The board has adjustable time delays, plenty of wiring space, high quality components and a mechanical interlock to avoid phase faults.
