@KangooNomad had almost the exact same thing on the narrowboat last autumn — Multiplus-II 48/3000, woke up one morning to Error 11 out of nowhere after a perfectly normal night. Turned out my...

Compressor surge got me too on the narrowboat last winter — woke up at 2am to that familiar relay-click silence. What solved it for me was fitting a soft starter on the freezer.
@DailySolar the suspense is killing me more than my battery bank in January ☠️ @ForestDaz probably right about the assistant config — in my experience the ESS assistant and the Generator Start...
Good points from @Spud and @RetiredChef on the regional mismatch. To actually answer the optimiser question though — yes, the OP-400 MV is compatible with the SE11400H family architecturally.
@RustySpanner I've got a similar setup on my narrowboat — 200Ah Fogstar Drift LiFePO4 running a small Shoreline chest freezer overnight.

Reply by CotswoldVanLifer: @RussScott the 100/30 is a cracking bit of kit, you'll be chuffed once it's all wired up!
@CrispyTrekker yeah the standing charge is the silent killer isn't it. Even when I'm parked up and the motorhome's doing all the heavy lifting, the house meter is still ticking away at around...

DaleSpirit | 312 posts Had almost the exact same situation with my static caravan setup last summer — two banks that had drifted apart in resting voltage after I'd been running them separately for...

@George1972 never heard of Humsienk — is that a brand or did autocorrect have a stroke? 😄 Joking aside, pairing a mystery-brand battery with a North American inverter on a UK forum is a bold move.

@LisaStewart71 is on the right track, but worth knowing the Multiplus 3000 has a 6000W surge rating — should handle most freezers in theory.
Worth clarifying what you're actually trying to do here @HO_Marine — proper grid-tie microinverters (APsystems, Enphase, Hoymiles) are designed to feed back into a mains supply, which is fine if...
@ExFarmer the RVC Combox is the bit that'll save your sanity here — it acts as the translator between the Southwire's proprietary RV-C protocol and something the Ekrano can actually make sense of.
@CotswoldNomad both valid points but honestly the relay tripping could just be the universe telling you to upgrade 😄 Had this faff with my garden office setup (different beast I know) — turns out...
@RustySpanner done this on my boat setup. Short answer: yes, comfortably — but depends on the freezer. A decent small chest freezer (60-80L) typically draws 30-50Wh per hour once it's up to temp.

@OffGridDawn yeah the stale fuel thing is real — ethanol in UK petrol is brutal on carbs if left sitting. Before pulling it apart, try this: Drain whatever's in the tank completely Spray some...
Cross-Europe solar is genuinely straightforward — Victron kit speaks every language and their VRM portal doesn't care which country you're parked in. Biggest gotcha nobody mentions: keep your...

@Spud is right that the SE11400H-USSNBBL14 is firmly a North American unit (240V split-phase, 60Hz), so it'll never play nicely with UK 230V/50Hz grid regs — full stop. That said, the OP-400...
@George1972 — the EG4 6000XP is a North American inverter and fairly uncommon over here, so you'll get limited UK-specific experience with it. That said, Humsienk use a fairly generic RS485 CANBUS...
Great topic @HO_Marine! For plug-in solar (I assume you mean grid-tie microinverters feeding back into your hookup supply?), the names that keep coming up are Hoymiles and Enphase at the quality...
@Squib the chest freezer compressor startup surge is almost certainly your culprit. Old compressors are brutal for inrush current — easily 6-8x running draw for that first half second. Few...
