Using MultiPlus via MK3-USB as a generator-charger alongside with existing a 3-phase Quattro system
Been mulling this one over since I saw a similar setup discussed elsewhere, and it's got me thinking about my own situation. I've got a modest boat installation — single Quattro 48/5000, Cerbo GX,...

DESS stops compensating self-consumption
@Rob1963 had something similar on the boat last autumn — not DESS specifically but the Cerbo started making odd decisions after a VRM firmware push.

Victron Multiplus 24/3000/70 and Waveform
Been wrestling with this one for a while on the boat, so thought I'd throw it open here. Running a Multiplus 24/3000/70 and during sunny spells the solar is absolutely hammering it — batteries...

New 12V/24V to 48V DC-DC Boost Converter for 48V DC Loads
Been keeping an eye on this space for a while now, particularly since I run a mixed-voltage setup on the boat — 12V for the older legacy kit and 48V for the newer Victron stuff.

Anyone else finding the days getting long enough now to finally stop worrying about battery levels?
Noticed it this morning actually — woke up to the Victron app showing 94% SOC before I'd even put the kettle on.

Generator keeps cutting out mid-cycle - faulty AVR or something else?
@SteveBurns99 that flickering before the cutout is the tell-tale sign — had exactly that on my boat's backup genny two winters ago.

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
Something worth adding from my narrowboat experience — the SmartShunt's accuracy lives or dies by how well you've configured it. I spent three frustrating weeks last winter convinced my Victron...

Victron Orion 30A keeps cutting out on long motorway runs — anyone else had this?
@GlenWard @OllieThompson73 — thermal's a classic one, but before you assume that's the whole story, worth checking your alternator voltage too.

6k5: Dynamic current limiter - physical Relay/Contactor?
Been mulling this one over after a similar rabbit hole on the boat last summer. I'm running a Victron Multiplus 48/3000 with a Honda EU22i as backup, and the dynamic current limiter via VE.Bus is...

EV Charging Station W-104 GX Communication Warning after Network Change and Firmware Update
@CarlWalker this rings a bell from when I rewired my own narrowboat setup last autumn. After a firmware jump on Venus OS Large, my Cerbo GX completely lost its head about anything on the CAN-bus —...

Anyone else finding cheap AliExpress BMS units are actually decent now?
Del | Posts: 2,156 | Joined: 2017 Boat life taught me hard lessons about cheap BMS boards. Had an unbranded unit fail silently on a 12V house bank — no fault signal, no cell balancing, just...

Anyone else using a second-hand EV battery as a home backup — what's your setup?
Bit of a different angle from me — my EV battery isn't a home backup, it is the home. Got a second-hand Hyundai Ioniq pack fitted to the boat about eighteen months ago.

Confused about MPPT sizing — am I overcomping my controller?
Del | 891 posts @KateMitchell73 @BoatMick has already covered the cold Voc spike, so I won't retread that. What I will say — from bitter experience on my boat — is that "overcomping" the...

Bypassing the AC output from Multiplus
Had a similar head-scratcher on my narrowboat setup. The bit people often miss is that bypassing the AC output entirely defeats the UPS functionality — which on a boat (or van) is actually one of...

Is it bad for the charge controller when the battery is full and solar is still coming in strongly so it has to shut off?
What @Davo79 said about the panels is spot on, and it actually took me a while to wrap my head around that when I first set up my boat system. The bit that clicked it for me was realising the...
