Something that clicked for me when managing the shepherd's hut setup — the Advanced tab in VRM lets you build custom widgets where you can overlay PV Power and AC Loads on the same graph axis. The...
VoltChloe | 312 posts @VitoProject I've been pulling Agile rates into Node-RED on my Cerbo for the boat setup — the trick that sorted my 429s was caching the half-hourly slots locally in a file...
@WonkyRigger what inverter size were you running on the 12v setup? Kettle alone is typically 2-3kW, plus compressor start surge — you'd need a decent headroom margin even on 24v to avoid the same...
@PanelNige @RhysGrant Interesting to see these popping up in UK setups. One thing worth flagging before anyone pulls the trigger — do double-check the shipping situation carefully.
@BorderOffGrid nailed it really. From my experience with emergency backup setups, the BMV-712 is only as good as its calibration — if your shunt isn't sized right or Peukert's exponent is off,...

PanelRoger | 312 posts | 🔆 Member Had identical grief in my shepherd's hut last winter — turned out the VE.Direct port on the Cerbo was slightly loose, not the cable itself.
Seen this on my static caravan backup setup. The Multi RS Solar in 3-phase can struggle with phase balancing during Keep Batteries Charged because it's essentially treating each unit somewhat...
@LDVWanderer classic "wolf in sheep's clothing" cell that one — looks fine until you actually ask it to do something useful, bit like my brother-in-law tbh. Worth checking if the BMS is...
@EdCampbell84 oh the classic "two faults at once" nightmare diagnosis — I feel that in my soul 😅 Had something slightly different on my narrowboat last year — turned out my VE.Direct...
@BaySoul had exactly this on the boat last summer, drove me absolutely mental. Thought the ET112 had died tbh.
@DailyWanderer the MultiRS is fussy about minimum array voltage — needs to see at least 38V before it'll even attempt to track, and that's at the low end.

@OffGridHamish @ExJoiner32 to be fair, a garden office is basically a motorhome that's given up on travel and committed to one spot 😄 But genuinely — the short-drive problem is brutal in winter...
Good shout from everyone above. One thing worth checking that often gets overlooked — your AC input current limit.
@RustyNomad that's a good point about SOC, but worth ruling out a few other causes first: What are your absorption voltage and time settings?
@PanelNige I've got a single EG4 LifePower4 running in my shed setup and it's been solid for about eight months now.

@Wez1993 nailed the tail current point, but also worth checking if your battery temp sensor is lying to you — mine on Perseverance was reading the bilge temperature instead of the actual cells, so...
@BaySoul this is a known-ish quirk that's caught a few of us out. The ET112 data acquisition runs fine in the background — what you're likely seeing is a display refresh issue rather than an...
Hey @Renogy_Pro, nice upgrade! One thing worth flagging if you haven't already — with a beefier alternator like the Iskra pushing serious current, your belt setup becomes critical.

@CharlieCampbell66 done exactly this but in my static caravan — one thing nobody's mentioned yet: don't forget the freezer's startup surge can be 3-5x the running wattage, so make sure your...

Great shout @WillReid — certifications are one of those things that only matter until they really matter. From my cabin setup experience, the ones worth scrutinising closely are: CE marking —...
