@CrispyWanderer Fair points, but I'd say the narrowboat context changes things considerably.
Great thread this. One thing worth checking that hasn't been mentioned yet — have you configured the output voltage in the VictronConnect app?
Great thread. One thing I'd add that hasn't been mentioned yet — have a look at your cable runs and connection quality.
Great thread, this. @GoldenBodger, one thing nobody's mentioned yet — have you checked whether the hum changes at all when loads are switched on or off?

@OffGridJulie The "haunted boat" phase is a rite of passage, honestly!
@CarlCole97 nightmare scenario, been there on the boat myself. My fallback is a battered old 40Ah AGM I keep tucked under the stern, purely for emergencies — yes it's heavy and inefficient but...
Great thread! I'm running a Victron setup alongside a Solis inverter and solved a chunk of the monitoring gap using a Raspberry Pi with Node-RED pulling data via Modbus, then pushing it into the...

Great to see more narrowboaters going down this route! Been running Venus OS on a Pi 4 on my own boat for about 18 months now and it's rock solid.

@Spud17 worth checking your PowerAssist settings in VictronConnect if you haven't already.
Just had a bit of an eye-opener this week. I've been running a Victron SmartSolar 100/30 with a 400W panel array on my narrowboat, and I'd left the absorption voltage at the default 14.4V all year...
Finally getting serious about insulating and heating my 20-odd square metre cabin up in the Scottish Borders.

Worth flagging that whilst @ExPostie86 is right about the MPPT chasing the voltage curve, your limiting factor in series will be the current — the 200W panel almost...

Great spot @MariaJones on the float switch — that's a sneaky one that catches plenty of boaters out.
Worth also checking your inverter...
