So my Victron MPPT 75/15 has decided to go on strike mid-week, which is absolutely peak behaviour considering I've got the garden office running off it and a deadline looming. Here's what's going...

The thing that catches most people out after the engine detection faff is the charge algorithm settings — the Orion defaults don't always play nicely if your leisure battery is lithium.

Barry1965 | 847 posts | West Yorkshire @Davo49 Ha, the eternal struggle! I went through three different configurations before I got mine settled.

Had a similar head-scratcher with my motorhome setup — running a DC-DC charger (Victron Orion-Tr Smart, naturally) off the engine alternator to keep the leisure bank topped up, and it made me...

Been thinking about this one for a while actually, as I've got a similar dilemma coming up with my van conversion build. I'm running a 100Ah Fogstar Drift LiFePO4 and I want to add a small...

@ThistleTel nailed the VE.Direct angle. One more thing worth checking — in VRM portal itself, go to Advanced and look at the device list.
Ha, @VoltageViking, duck contributions are a whole other category of panel contamination! 😄 I'm on a static setup in the Welsh borders and the oak pollen this spring has been something else —...

Been through exactly this with my shepherd's hut setup, so hopefully some of this is useful even though you're in a van. The short answer is: one leisure battery almost certainly isn't enough,...
@LizStewart — on the MultiPlus-II, "Solar Priority" is essentially achieved through the ESS (Energy Storage System) assistant rather than a standalone toggle.
SimonThompson replied: Had this on my narrowboat setup too — worth checking your alternator output voltage under load.

@ExSquaddie49 When you say they cannot be paralleled — are you referring specifically to the parallel function in the traditional Victron sense (same model, same firmware, VE.Bus synchronisation),...
Been running a Growatt SPF 3000TL on my narrowboat for about 14 months now and it's held up reasonably well, though I did have an early firmware headache getting it to communicate properly with...
Seen this exact gremlin in my motorhome — Victron's low battery threshold is calculated against a loaded voltage, so if your BMS is reporting resting voltage but the Multiplus is measuring under...
Running a narrowboat and trying to figure out if a single 200Ah lithium (Fogstar Drift 12v) is going to cut it for keeping a small chest freezer going overnight without the engine running. The...

@Renogy_Pro what current output are you actually getting through to the 20Ah though? With such a small bank I'd worry about over-speccing the charge rate and stressing the cells — most B2B...

Been having a weird one with my Victron ESS setup in the shepherd's hut lately and wondering if anyone else has seen similar. My system is single phase rather than 3-phase, running a Multiplus-II...

@NotAnElectrician80 makes a good point on ESS — worth adding that once ESS is configured, you'll want to set your minimum SOC carefully so the system isn't constantly trying to discharge to grid...
Had something almost identical happen with my setup last year — Victron Multi-RS 48/6000 refusing to budge out of storage mode even though the JK BMS was communicating perfectly with the Cerbo GX.

CamperSam replied: @SmartSolar_Queen Right, ignoring the forum gobbling up half these posts like a hungry seagull... Classic MultiPlus charger dropout.

Been having a nightmare with this exact thing on my narrowboat setup and wondering if anyone else is seeing it. Running a Cerbo GX alongside a pair of Victron SmartSolar MPPTs and a MultiPlus-II...
