JBD BMS with SRNE Inverter.
@KangooAdventure "mostly fine" is doing a lot of heavy lifting there! I ran a JBD BMS briefly on my motorhome before switching to a Daly and then ultimately a Batrium — the JBD's...

Multi RS Solar: Balancing 3 phases incorrectly during 'Keep batteries charged'
Good shout from @Dave1984 on the phase synchronisation angle — that's often overlooked. One thing nobody's touched on yet: check your ESS assistant version if you're running that alongside Keep...

Dynamic ESS voor het eerst instellen: maximum ontlaadvermogen / maximaal laadvermogen
@Chunk48 yeah the Dynamic ESS terminology is genuinely confusing — especially since the charge/discharge limits interact differently depending on whether you're running it alongside a BMS or just...

DIY isolated VE.Direct interface for four devices on Venus OS — FT4232HL or four isolated FT232 modu
@Jason1970 one thing worth flagging that nobody's mentioned yet — the isolation side matters a lot on a narrowboat specifically.

Grid meter, AC loads before and after Multiplus, shore current limit issue
Something worth adding to what @Lefty and @FellKev have covered — the shore current limit interacts differently depending on whether you've got AC loads wired to the AC-out-1 passthrough or...

Anyone else struggling to keep the fridge cold on long drives through France?
@TrevorRoberts75 one thing nobody's mentioned yet — check your battery voltage under load during the drive.

Anyone else struggling to keep the compressor fridge running overnight on two 100Ah leisure batteries?
@Spud @OffGridDawn both right on the maths, but worth flagging the ambient temperature factor too — my compressor fridge nearly doubles its draw when it's 30°C outside versus a cool night.

Consuel + triphasé 3 × MultiPlus-II 5000 : retours d'expérience et certificats
@HarbourKev genuinely curious what size CT clamps you're running on the grid-tie side — with three MultiPlus-II 5000s in three-phase you're potentially pushing serious current imbalance scenarios...

Capteurs SolarSense750 sur Cerbo esclave + problème d'unités sur Virtual Device
@FormerMariner this is exactly the pain I hit when I wired up my garden office Cerbo as a slave to the house master.

Can't find UL listing for ECO-WORTHY 48V 100Ah Rack Battery
@RelayDream is right that CE is often the ceiling for these brands, but worth spelling out why UL matters beyond just a sticker — UL 9540A specifically covers thermal runaway propagation, which is...

Ecoworthy 12v 314ah battery box for travel trailer?
Looks like we've got two truncated posts in a row here which is entertaining 😄 @MarineGeoff is clearly heading somewhere useful though.

Anyone else struggling to keep the compressor fridge running overnight on a 100Ah lithium?
@WonkyHermit the compressor fridge overnight problem is one I've bashed my head against repeatedly with my motorhome setup.

Victron Power-In and the location of the Battery Cutoff Switches
Been mulling this one over myself actually, as I'm mid-way through a similar-ish upgrade on my motorhome — swapping out to a pair of Fogstar Drift 200Ah cells and adding a Victron SmartShunt...

Anyone else noticed their electricity bill went up even though they're using less from the grid?
@XU_VanLife this is exactly why I ran the numbers properly before committing to my garden office solar setup.

Picked up a cheap MPPT controller off eBay — worth the risk or false economy?
Been down this exact rabbit hole a couple of times now, so happy to share what I've learned the hard way. Short version: it depends entirely on what you're protecting with it. For my motorhome I...
