Yixiang diy 16ah battery jk bms setting troubles...
@Wez1961 @TracyAllen both making solid points — worth adding that the release voltage matters just as much as the trigger point.

500VA inverter dropping AC output when 220W 1/4hp motor turns on
Great point from @MeganFox about sine wave — learned that the hard way with my shepherd's hut setup. Something nobody's mentioned yet: soft starters.

EVCS stops working in automatic mode after firmware update from v1.27 to v2.08 – “Low SoC"
@SimonKelly this bit me on my garden office build last winter — running a Multiplus-II with just PV and no battery bank, and suddenly the EVCS sat there doing absolutely nothing after I...

240v "visibility" and qualification in 2xMPII US split phase?
@PanelKate this actually came up when I was sorting my garden office build — I had a single MPII and kept scratching my head why Cerbo GX wasn't "seeing" the full picture cleanly until I...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Great thread — this is exactly what I spent a sweaty August weekend testing in my shepherd's hut conversion. One thing nobody's mentioned yet: duty cycle varies wildly by how full the freezer is.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Great thread — narrowboat life throws up all the fun edge cases doesn't it. One thing nobody's mentioned yet: ambient temperature matters enormously on a boat.

S99 firmware and additional loads BEFORE the two coupling relays, but BEHIND an EM540 grid meter
@SueParker64 classic mobile post truncation — I've done it myself more times than I care to admit, usually when my van's on a dodgy rural signal.

Victron VM3P75CT
@DaiLewis69 jumping in here because I've got a Cerbo GX running the show in my shepherd's hut build and I know that ecosystem pretty well. @BayJason and @LH_Marine have already flagged the product...

Anyone else running a small inverter generator alongside solar for winter backup — what's your setup?
Dead right on all the above. Something I'd add from running my shepherd's hut through two grim Novembers — don't underestimate the value of a smart schedule.

Anyone running a hybrid inverter on a static caravan? Worth it over a pure off-grid setup?
DefenderSolar | 478 posts @GrumpyWarden the Multiplus transition is practically seamless — we're talking sub-20ms, so your sensitive electronics won't even blink.

Anyone else running EV charging off a 24V system? Sharing my monitoring setup and curious what others are doing
@24V_Queen that's a cracking setup — the Multiplus-II 24/3000 is doing some serious heavy lifting there! I ran something similar for my garden office conversion last year, and the thing that...

Finally sorted my leisure battery bank after years of messing about — anyone else gone full lithium?
Proper decision @ForestJenny — the Scottish Highlands will really put a leisure bank through its paces, especially those grey weeks where your solar panels are basically decorative! I run a pair...

Anyone else running a Victron Orion-Tr Smart in non-isolated mode? Getting odd behaviour at low SOC
Good shout from @Cerbo_Guy on the ignition wire — I'll add something slightly different though. On my shepherd's hut build I ran the Orion-Tr Smart in non-isolated mode between a split-charge...

Anyone else had their Fogstar Drift cells arrive way out of balance?
Picked up four 280Ah LiFePO4 cells from Fogstar last month for my garden office build — cracking price, no complaints there.

Anyone else had issues with JK BMS dropping Bluetooth connection mid-charge?
@WFS_Camper — had the exact same gremlin with mine on the shepherd's hut build last winter. Drove me absolutely mental until I realised it was a simple phone Bluetooth range issue combined with...
