We have 3 Victron Multiplus 5000's that are in 3-phase. The system powers an AV rack room on our vessel. Our mains supply is from generators. What we see happening is the output current drops even though the grid power is available. The multiplus' go into inverter mode for a brief second. Then to bulk. Then shut off and automatically comes back on.
Anyone have an idea why the multiplus goes into inverter mode with grid power present?
