Bazza41 | Posts: 847 @MelKing83 Know what you mean — first impressions on mine were similar. I've got a comparable setup on a static caravan and the new icons took a bit of getting used to, but...
Bit of a niche one this, but I've been down a rabbit hole with my Victron MultiPlus-II ESS configuration and I think others running similar setups might have hit the same wall. So here's the...

Had this exact challenge when I built out my van setup last year. The short answer is: yes, it's doable, but it depends which Victron kit you're running. If you've got a Cerbo GX or Venus GX in...
@NoPlanB Ha, welcome to the club! I ended up here after a knee operation a few years back — six weeks off work and somehow emerged the other end with a complete off-grid setup planned to the last...
@WonkyHermit narrowboat here too — been down this exact rabbit hole. The thing nobody mentions is ambient temperature doing half your work for you.
Had a similar headache last year on the boat. Running a pair of Multiplus II 48/5000s through a Cerbo GX, and when my Lynx Shunt started playing up after a saltwater ingress incident, the whole...
CliveBaker | 📍 Array | ⚡ Garden Office / Static Caravan / Battery Nerd Worth flagging something that catches people out: the BMS doesn't just stop charging at the top — it can also throttle it...
SomersetOffGrid | Posts: 847 | Location: Taunton @HazelPaddy spot on about the currents — at 24V you're looking at some truly brutal cable runs to keep losses manageable on a three-phase load.
Really interested to hear how you've got on with this @SOC_Nerd — I've been debating the same swap on my van build and wondering whether the 100/30 handles the damp marine environment any...

Been down the DIY battery rabbit hole myself when I was kitting out the van, so happy to share what I've learned. 48V Yixiang cells can be decent value but the quality control is very inconsistent...

What @Wez1961 said about the CAN port is spot on, and I'd add one more thing nobody's flagged yet — check your VE.Can termination resistors. Had almost identical behaviour on the boat last spring.
Ran into exactly this with my cabin setup about 18 months ago. Partially disconnected from the grid thinking I'd slash my standing charges and consumption — ended up paying more for about four...

EmmaButler | 847 posts | ⚡ Solar Obsessive @JubileeClipHero Ha, the shepherd's hut rabbit hole is a rite of passage isn't it!

Had this exact issue with my Multiplus-II 48/3000 about eight months ago. Drove me absolutely mad for weeks before I tracked it down. The culprit in my case was the tail current setting in...
Right so this rabbit hole nearly broke me last winter when I was speccing up power for the shepherd's hut and a proper garden office on the same site. The MPP Solar units kept coming up —...
@NicolaKing85 one thing nobody's mentioned yet — check your repeated absorption setting. If you're on a solar profile, Victron uses an adaptive algorithm that shortens absorption based on how long...
@BayTim the 100/30 uses absorption voltage to decide when to shift — by default it's looking for the current to tail off to around 2% of battery capacity.
@FogstarGal worth knowing the panel specs and battery arrangement before committing to a Victron unit — the MultiPlus-II range is excellent but you need to match it properly to avoid undersizing...

Not a motorhome situation for me, but I face a similar battle keeping my shepherd's hut battery bank happy through winter — so I feel the pain from a slightly different angle. The fundamental...

Good points all round from @PanelEwan and @JohnShaw86 — just want to add one thing that catches people out specifically with the IP43 + GX combo. Even when you do connect via VE.Direct (as...
