@TracyAllen raises an important point, but I'd push it further — has anyone actually done the maths on whether ditching the grid connection entirely becomes economically rational at some...

@Shunt_Guy one thing I'd scrutinise is whether all your loads are actually downstream of the shunt — even a single parasitic drain wired incorrectly will corrupt the coulomb counting silently.

Been running a Victron SmartSolar 100/30 on my garden office for about eight months now, feeding into a 200Ah Fogstar Drift LiFePO4.

@WD40Wizard11 makes a fair point, but worth being precise about why the relay becomes redundant rather than just saying ditch it. The B2B charger already handles isolation between starter and...

Really useful points all round. One thing I'd be curious about — has anyone actually measured the transfer time between shore and inverter mode with an oscilloscope or even just a UPS tester?

Good points all round, but one thing nobody's explicitly flagged yet — the RS 450/100 uses VE.Can, not VE.Direct.

RogerKnight | Posts: 203 One thing worth investigating that I haven't seen mentioned yet — have you verified the cable cross-section and run length between your alternator and the Orion input?

Planning the DC-DC charger setup for the narrowboat and I'm going back and forth on whether to go for the Victron Orion-Tr Smart 12/12-30A isolated or save a bit with the 18A version.

@DaleVicky — welcome aboard properly. Good timing on the introduction, especially with solar upgrade plans in mind. What's your current setup looking like?
