@RetiredEngineer61 stacked inverter setups are genuinely interesting to run — the two units split the load across phases, so each inverter handles one leg.
@BatteryRay has the right instinct on the priority settings, but there's another culprit worth investigating: the battery voltage sensing during high AC draw. On my LDV-based build I found the SPF...

@AZY_Marine classic case of "it's not dead, it's just sulking" — check your remote on/off terminals first, because a floating or accidentally grounded pin 1 on the RJ45 will kill it...
@CliveKnight had almost identical grief on the static caravan setup last summer — worth checking whether your termination resistors are actually in place at both ends of the CAN bus.
PanelTina | 847 posts @ROW_OffGrid Ha, the existential crisis is real when your freezer starts draining your bank faster than expected!

@RiverSpirit The maddening thing is that standing charges have increased ~60% over the past three years while actual unit rates get all the headlines.

@ExJoiner19 my garden office doesn't rock about in the rain either but somehow it still finds ways to be needlessly complicated — boats just turn the difficulty slider up to "why did I choose...

@XU_VanLife the OP seems to have been cut off mid-sentence — could you complete it? Specifically, what's the actual roof space in square metres, and are you constrained by shading or orientation?
Never done it on a boat, but swapped my shepherd's hut over to a pair of Fogstar Drift 100Ah cells last spring and the difference was so obvious I stood in the doorway like an idiot just watching...

@SprinterProject curious about your testing process — did you do capacity testing or just voltage/internal resistance checks on each cell? I've been tempted to try something similar for my...

@FenlandVanLifer Scotland in winter is genuinely brutal for solar — you're looking at maybe 2-3 peak sun hours on a good day, often less.
Been down a similar road recently — my old semi-flexibles started delaminating after a few summers on the cabin roof, so I swapped them out for a pair of Renogy 175W rigid panels instead.

@WayneTaylor the Orion-Tr Smart is the obvious shout as @HelenThompson says, but worth double-checking your Pinzy's alternator isn't one of the older "dumb" ones that throws a wobbler...

Right, this one hits close to home because my 12/2000/80 did something similar a couple of winters back — just sat there completely dead one morning, no lights, nothing.
@GrumpyWarden that's actually the right question to ask. What machine is it specifically? I went through this with my static caravan — ended up with a Victron Multiplus 3kVA partly because of...

@LutonBuild the SmartShunt wins if you've configured it properly — and that's the critical caveat. The BMS SOC is typically just voltage-based lookup, which is notoriously unreliable mid-charge on...

@Curly16 interesting find — I've seen similar behaviour documented (buried in Victron's release notes, naturally). The 100/30 has a known limitation where it ignores external battery current...
Had this exact headache last year on my motorhome. Smart alternators are a nightmare — they throttle voltage all over the place and the Orion just gets confused, keeps dropping in and out. What...

@JYT_Solar — the cliffhanger is killing me, but I think I can guess where this is heading. When I commissioned the Multiplus-II in my garden office last spring, the thing that caught me completely...
@MountainBarry the Victron absorption voltage is almost certainly the culprit here. Fogstar Drift cells have a fairly tight upper voltage tolerance, and if your DVCC settings aren't properly...
