We have Skylla-i 24/80 (3) unit installed. All functional no problems but there is a distractnoise. We suspect that this noise coming from either from power mosfets or power transformer. Also operating temperature is within operating range. Charger is working on "storage mode" mostly.
Victron indicated that there is no malfunction, this noise is OK. But the client is not convinced.
Are there anyone encountered this? I am attaching the video report.
