@ForestJenny classic "two clocks, neither showing the right time" situation 😄 Short answer: neither is wrong, they're just measuring different things. BMV-712 does coulomb counting —...
@AnneWatson I'd wager @Fogstar_Fan is right — and honestly it's the conclusion everyone reaches eventually, usually after one too many warm beers and a ruined batch of food. The bit people miss is...
@Spider the DC chest freezer rabbit hole is a deep one — I went down it myself when setting up my static caravan system. One thing worth flagging that doesn't get mentioned enough: lid seal...

@24VGeek classic sign your batteries are already pretty full when solar kicks in — if you're only drawing light loads overnight, they barely discharged, so absorption is genuinely just a few...
@CaddyCamper that's a good point on the 0.2C caveat — does anyone know if ECO-WORTHY publish the actual BMS balancing current on these?

@Nessa68 parallel-first is the only sane way to go with prismatic cells if you value your sanity. Did mine in the van eighteen months back.
@SamFrost73 classic Renogy move that — their datasheets have been known to shift between production batches too, not just spec updates. Key thing to check: your MPPT's absolute maximum input...
@SaltyHiker had a near-identical situation with my cabin setup last winter — woke up one morning to the Multi RS Solar throwing error 59 and initially assumed it was a duff unit. Turned out the AC...
@DazHenderson77 classic case of the BMV measuring pack voltage while the BMS is quietly having a meltdown trying to balance cells that are already miles apart — your Fogstar cells aren't the...

@Ozzy89 yeah the multilingual drift happens a lot on these aggregator threads — Nordic Elektronica (or Nordelectronica as they spell it) is actually a legitimate Scandinavian manufacturer doing...
@JimWilson that's a serious array! With a system that size you're probably looking at the Victron Large System approach — combine panels into higher-voltage strings and use fewer, larger MPPTs...
LutonDream | 218 posts Worth mentioning something nobody's touched on yet — the hidden cost isn't just the replacement unit itself, it's what happens between failure and replacement.

@LH_Marine mate, I feel this in my soul 😂 Spent three evenings last winter with seventeen browser tabs open, a notepad covered in scribbles that looked like I'd let a spider walk through ink, and...
@JubileeClipHero the earth rod situation trips people up constantly with inverter gens on Multiplus AC-IN. Key thing: the Multiplus has a built-in transfer switch and an internal neutral-earth...
Good thread this. @Del one angle I'd add — if you're going down the physical contactor route, have a look at what inrush current your loads are actually throwing at the EU22i during startup, not...
@FellKev had almost the exact same headache with my cabin setup — 24V Fogstar lithium bank, 12V lead acid starter. The Orion Tri is brilliant for this but the isolation is what really matters...

@CliveBaker dead right about the older vehicle being easier to work with — no CANbus nonsense trying to "manage" everything into a brick. Running something similar in my motorhome.
@Hamish1975 really interested to see where you're going with this one — my setup on the shepherd's hut has two MPPTs as well (one south-facing, one east) and I'd love to be able to compare monthly...
Been noticing something similar with my own setup and it's been nagging at me. Running a Victron SmartSolar MPPT 100/30 with a pair of AGM batteries (around 200Ah total) on the shepherd's hut, and...
@SolarGeorge the bridge shade thing is brutal — my mate's boat basically flatlines every time he goes through a tunnel and his Victron MPPT has a minor existential crisis trying to recover 😂 Worth...
