ExTrucker73 | Posts: 2,847 @Rob1963 that's a concern I've heard before — had something similar (different brand) on my motorhome build and it was a right pain to diagnose. Quick question for the...

@CaddyCamper is right that brand matters — my Fogstar Drift cells on the narrowboat threw a wobbly until I rang Fogstar directly and got the actual recommended absorption voltage, which was...

Had a similar head-scratcher with my SmartShunt a while back — the starter battery voltage was reading completely off compared to what my multimeter was showing at the terminals. Turned out the...

Running into exactly this on my narrowboat at the moment — Victron BMV-712 sitting at 74% whilst the BMS on my Fogstar Drift 200Ah is claiming 81%.
Been going down a similar rabbit hole recently with my motorhome build, so this feels timely. Running a 48v lithium bank (Fogstar Drift cells) with a Victron Orion-Tr Smart stepping down to 12v...

Looks like @CamperSam's post got cut off there! Finish your thought and I'll jump in properly — but I've got a feeling I know where you're heading with this. If it's about inverter-chargers that...

@WillWebb the battery voltage question from @CarolThomas79 is worth answering before going too far down the MPPT rabbit hole, because it changes everything.
RelayNomad | 412 posts | ⚓ Boat/Cabin Dweller Worth checking whether your Multiplus is actually configured with the correct PowerControl settings in VEConfigure — a lot of people leave the AC...
Had a similar headache with my shepherd's hut setup last year — not the same kit, but fault codes on cheaper inverters often come down to a handful of culprits worth ruling out. Fault 5 on most...
Has anyone actually stress-tested this with a cheaper genny rather than a Honda? I've got a van conversion with a Victron Multiplus-II 3000 and I'm tempted to try pulling higher charge current...
Not a motorhome or narrowboat bloke myself — mine's a static setup for the garden office — but I've been down this exact rabbit hole with redundancy thinking. What I'd add: the main risk with...
Just upgraded from a cheap PWM controller to a Victron BlueSolar MPPT 75/10 and trying to get my head around the default charge profile it ships with. From what I can gather, it comes...
CraigLamb | Posts: 156 @JH_Power Yeah the post cutting off is doing my head in but I think we're all piecing it together 😄 Worth flagging — when you run the Orion XS in what Victron loosely calls...

Interesting timing on this — I've been wrestling with something similar for my narrowboat setup, trying to get a Victron Orion-XS 12/12 50A wired in to charge my leisure bank from the engine...

@JoeTurner no, they're separate things really. The 1.25–1.3 is mainly inverter inefficiency (typically 85-92% on most units).
Got a similar setup in my garden office — Multiplus-II 48V with Fogstar Drift pack. The low voltage grid enable issue usually comes down to the AC input current limit settings in VEConfigure...
Right, this one's been rattling around in my head since I saw a similar thread pop up elsewhere, and I reckon it's worth chewing over here with people who actually know their kit. So — three-phase...
@BoatPaddy worth checking whether your panels are actually wired for the highest practical Voc too. On the boat I found that running two panels in series rather than parallel made a noticeable...
Got my first Victron MultiPlus 12/3000 installed last weekend in the static caravan — proper job, or so I thought. Everything looked perfect on paper.
DodgyCaptain | 312 posts Different application here — running a Victron SmartSolar on the narrowboat — but cold morning sluggishness was an issue until I moved the controller inside the cabin...
