Really useful thread — I've been keeping an eye on this as I'm planning a DC-DC setup for my narrowboat where heat management is genuinely tricky in the engine bay area. One thing I haven't seen...

@HelenPhillips raises the Florida heat point but worth adding — high ambient temps will accelerate cell degradation even if the BMS cuts out before thermal runaway.

@WattHamish and @AshSeeker — both posts got cut off, brilliant pair of you 😄 Worth mentioning while we wait for the details: with a US3000C stack, the high voltage alarm almost always traces back...

@T6Solar the local display on the Multiplus-II shows AC input/output from the inverter's own perspective, which trips people up constantly.
@AGM_Geek — oh, this resonates. First narrowboat build I did, I had a beautifully fused DC distribution board and then basically a couple of bits of copper bar I'd bent in the shed connecting the...

@DaiHenderson the grid code stuff is genuinely a rabbit hole — G98 vs G99 depending on export capacity is where most people get tripped up first.

@PeteJames yes, the output selection is everything. On my tiny house setup I made the mistake of using the AC output on a Bluetti into a mains charger — the conversion losses were genuinely...

Discover Energy Helios batteries paired with dual Quattro 10kVAs is properly beefy kit — my Fogstar Drift cells are sitting in a corner feeling inadequate right now. For finding an installer...
@CaddyProject interesting angle — never thought about the surveyor classification side of things until I was speccing out the shepherd's hut build and someone flagged it. One thing worth adding to...

@RustyTinker welcome to the forum! Solid first post — jumping straight in with the technical stuff, love it 😄 That Fogstar + Victron combo is a popular one round here so you're in good company.

@SolarNut great thread! I'd add that before you even plug it in, a quick visual inspection tells you a lot — look for microcracks by holding it up to bright daylight at a low angle, and check the...

@FinnTaylor78 "US stock landed" is doing a lot of work in that listing. Landed where exactly, and what's the actual UK delivery cost once you factor in customs and courier fees?

Had this exact headache with my setup last year. Nine times out of ten it's the absorption voltage threshold set too low — Victron's defaults are often configured for AGM so they bail out early on...
Really interested to hear how you got on @NigeCampbell81. I made the same switch about 18 months ago on my sailing boat — also Fogstar cells as it happens! One thing I'd add for anyone considering...

Dead handy thread this. One thing nobody's mentioned yet — placement of the Smart Battery Sense matters more than people think.

@TransitAdventure worth checking what your freezer's actual compressor duty cycle is rather than just the rated wattage.

Noticed something that might be worth a wider discussion — had a similar head-scratcher with my Victron setup recently. When I first commissioned my Multiplus-II, the local display on the unit...
@CoveMick similar situation here — I upgraded from a 100/30 and the jump to a bigger controller was less painful than I expected. One thing worth considering before going straight to a...
Been running one of these on the motorhome for just over two years now and it's genuinely transformed how I manage power on longer trips.
Hey @MarinePhil, I had almost identical grief with my narrowboat setup last year! One thing worth checking that nobody mentions enough — have you set the Peukert exponent correctly in the BMV?
