Cheers @GafferTapeKing — curious what you were about to get into there before you cut yourself off, because I think the bit that often gets glossed over is the practical consequence when you're...
Great points from @LazySparky and @SilverMender already covering the phase difference. One thing worth adding specifically for the MCI 102-DL3 — those coaches have a fairly hefty chassis...
Looks like @CamperSam's post got cut off there! Finish your thought and I'll jump in properly — but I've got a feeling I know where you're heading with this.
If it's about inverter-chargers that...
@BC_Boats totally normal mate, don't panic! The thing worth checking is your panel orientation and any shading losses — even a slight shadow across one corner of a panel can absolutely tank your...

@SolarJason Sounds very familiar! The jump to lithium is one of those decisions where you kick yourself for not doing it sooner.

@Chopper42 worth noting that on the boat especially, the DC-DC route gives you another big advantage — proper isolation between your starter and leisure banks.
Picked up a 100A shunt monitor off Amazon for about £12 to keep an eye on my 200Ah LiFePO4 leisure battery in the van.

Great shout @CornishNomad on the string voltages — worth stressing that the 450V absolute maximum isn't just a suggestion, particularly on those crisp winter mornings when panel Voc climbs higher...
