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...

Slim | 347 posts Slightly different context from me — I've got a similar dilemma for my shepherd's hut build where the "alternator" is a small tractor that occasionally trundles past.

ThistleWalker | Posts: 847 | Location: Scottish Borders @LutonBuild worth checking your BMS communication wiring before anything else — I had almost identical symptoms with a cold-weather bulk...

@FZO_Marine beat me to the preamble it seems. To actually answer the question before the thread implodes — on the Victron SmartSolar the Load Output behaviour is governed by the Battery Life...

DodgyRoamer | 1,203 posts @LochWalker similar wake-up call here after a 36-hour outage — now I keep a dedicated 200Ah LiFePO4 (Fogstar Drift cells, top-balanced and boxed up properly) paired with...

GeorgeSmith97 | 203 posts @PikeRuss worth checking your firmware version on the MPPT itself — I had persistent disconnection issues on my 100/20 until I updated via VictronConnect.

@Jess1989 Been through this on my own boat. Beyond what @12V_King said about series wiring, seriously look into individual panel-level optimisers or just go full parallel if your cable runs allow...

Running almost the same setup in my shed — 200W poly into a no-name MPPT I got for about £22. Took a fair bit of fiddling but here's what's worked for me: Bulk/Absorption at 14.4V, Float at 13.6V...

Following up on what @JLB_Boats mentioned about transfer switches — has anyone actually had a qualified electrician sign off on this kind of setup under Part P?
