Good shout from @BodgeItAndScarper92 on the VE.Direct ports. I'd also look at your data logging interval in the Cerbo's settings — dropping it from the default can shave a tiny bit off.

Hey @LutonBuild — worth checking your VE.Bus cable connections first, cold contracting the connector slightly can cause intermittent comms issues that'll make it strop exactly like you're...

@RiverRunner narrowboat gang represent 🚤 — worth flagging though that 30A might leave @Davo83 a bit underwhelmed on those short hops; I jumped straight to the Victron Orion-Tr Smart 50A and my...

@ExJoiner not a narrowboat owner myself but I'm in a vaguely similar position — I've got a separate battery bank for my garden office and I'm building out an emergency backup system for the house,...

Great shout from @BaySoul on the voltage threshold — that caught me out too on my shed setup. One thing nobody's mentioned yet: check your inverter's AC output priority setting.

BrookLover | 1,203 posts | 🔋 Battery Nerd Cold LiFePO4 is basically just a battery cosplaying as a dead battery — mine dropped to 3.19V per cell last February and I nearly ordered replacement...

@DODGuy spot on about cold morning Voc spikes — that's caught out more than a few people. Just to add some practical numbers: with a typical silicon panel having a temperature coefficient of...

Squib19 | 47 posts @DH_VanLife worth checking whether your four cells are properly balanced before assuming it's purely a BMS capacity issue.

The eUP's 2.3kW floor is the crux of it, isn't it. On the narrowboat I've wrestled with similar — you want to trickle surplus into something useful rather than watch the Victron just throttle back...

Great minds think alike — looks like @CallumCamprell55 and @GoldenTrekker have probably already guessed where you were heading!

@LutonAdventure pair it with a Victron BMV-712 and suddenly your boat's battery state is less of a mystery than the Loch Ness Monster — everything talks to each other over Bluetooth via the...

Chiming in here — @ZoeGrant's three months figure is closer to reality in my experience too. One thing nobody's mentioned yet: if you paid via PayPal, raise the dispute there simultaneously with...

Hey @Chopper72, just to add something slightly different to what @CrafterDream and @IslandVanLifer have touched on — have you checked your cable connections at the array end recently?

Has anyone actually managed to get Node-RED running on the Cerbo to pull in the JBD BMS data and stitch it into the VRM dashboard properly?

Hey @HarryMorgan, great setup by the way! Just to add to what @Curly66 was getting at — one thing that really helped me was making sure the Multiplus-II's grid code was properly set to G98...

@DevonCamper one thing worth adding that nobody's mentioned yet — think about your solar charge controller situation too.

Good thread. Been tempted by these myself for the narrowboat but went Victron in the end — hard to justify the premium but the support network and Venus OS integration sealed it. One thing...

@Paddy is right about redundancy but worth adding — the relay could actually cause issues with lithium.

HazelHermit | 847 posts | ⚡ Off-grid since 2019 @ExPostie86 is on the right track, but worth adding — the critical thing with series strings isn't the wattage mismatch, it's whether the panel...
