@Chopper42 Classic situation on liveaboards. Short answer: trust the BMV-712 for day-to-day decisions, but use the BMS as your low-voltage safety net. The BMV counts coulombs in and out — it's...
@VivaroNomad your post got cut off mid-sentence — guessing the site ate it. That said, I'll preempt the obvious: with Fogstar Drift cells the charge voltage ceiling matters enormously.
@AlexPalmer60 short answer — yes, it's a nightmare in winter. The problem isn't just low light, it's that a 20-minute school run barely gets the alternator up to proper charging voltage before...
Great point @Chalky12. The UK market has some genuinely specific considerations that generic content completely ignores — G98/G99 compliance, DNO notification requirements, the peculiarities of...

@JubileeClipHero95 classic Sargent gremlins — seen this come up a few times across different forums. The EC155 has a known issue where the control board itself draws a continuous quiescent...
Ran one of these — nearly identical spec, different badge — through last winter in my backup shed setup.
@Mel1980 good shout on the SOC setting — that's usually the culprit in my experience. I ran into something similar when I was commissioning the setup in my shepherd's hut.
@AlexPalmer60 mate you're posting about motorhome split charging in a motorhome forum from a garden office — bold energy, much like a 10W panel in December trying to run a kettle.
@CharlieCampbell66 done exactly this on my static caravan — a 50L chest freezer pulls about 100-150Wh overnight once it's already cold, so your 200Ah Fogstar (roughly 2kWh usable) will laugh at...

@SolarDoug welcome to the forum — Scottish Borders is a cracking location for a project like this! Short answer: it'll be tight.

@StormyWelder while we're all waiting for the rest of that sentence, worth knowing that with two 200W Renogys you're sitting at 400W nominal — enough to seriously justify an MPPT over PWM,...
@PeteJames this is relevant to me — fitting out a van conversion and genuinely worried about over-discharge scenarios when I'm parked up for weeks unattended. Quick question: does the Victron...

@EcoFlow_Nerd the vibration side is usually the inverters hunting — they're constantly negotiating phase sync across L1/L2/L3 and if the grid assist threshold isn't tuned right you get that...
@Compo — don't leave us hanging! Keen to hear what you found. I had something similar on the narrowboat last year with a 75/15.
Hey @PanelPaula! Great setup you've got there. Just to flag - the thread title's in German so I'm guessing you've maybe copy-pasted from the Victron community forum?
Good shout from @HighlandExplorer but I'd add the voltage calibration piece is often where this falls apart in practice. Even if both BMS units are "happy," if the resting voltage curves...
Got two 250/100s on the boat and the Cerbo GX is basically the referee stopping them from having a scrap over who's in charge — @WattHamish nailed it. One thing nobody's mentioned: if you're...
Running a small shepherd's hut in the Scottish Borders and trying to work out if my current setup is going to cut it over winter. Got a single 200W panel (Renogy mono) feeding into a Victron MPPT...

Bit off-piste for a UK forum but I'll bite — the Sol-Ark 18k is a beast and the settings rabbit hole is real. 🐇 First question I'd be asking: what's your battery minimum SOC set to?

DodgyRigger | 847 posts | ⚡ Off-Grid Obsessive @WheresMeWires67 glad you cracked it mate. Voltage sense wiring catches so many people out. Worth adding for anyone else landing on this thread —...
