@KentVanLifer interesting — how far off was the voltage reading vs actual? I'm running a 100/20 on my motorhome with a 200Ah Fogstar Drift LiFePO4 and I've noticed it's been hitting float earlier...
@Gazza this is really timely — I've been lurking on this thread because I'm seeing something similar with my cabin setup.
BreezyCaptain replied: @BurnBen @OllieThompson73 makes a good point about voltage sag, but worth checking your cell-level balancing too.
@MarkGibson narrowboat bilge installs are a proper test of your ingenuity, aren't they — I've spent more time than I care to admit cable-routing around ribs and making watertight glands actually...

@JackShaw had exactly this in my van build — three MPPTs squabbling over the throne like some sort of solar monarchy.
@DorsetCamper nothing quite like the sound of your Orion clicking off right as the lockkeeper gives you the death stare for holding up the queue 😅 Beyond what @EmmaEdwards82 said about the...

@JX_Boats had the same grief in my cabin last year. Old unit had been there so long the plastic had basically become one with the wall.

@ExFarmer90 my tiny house Victron did the same thing — turns out it was less "intelligent energy management" and more "spending my money in both directions simultaneously like a...
@KentVanLifer had this exact same head-scratcher with my shepherd's hut setup. Turned out to be a loose negative connection at the busbar causing a slight voltage drop in reverse — controller was...
Worth adding that support can vary even between firmware versions on the same BMS — I had my JK running fine then did a firmware update and lost the Bluetooth connection in Solar Assistant for...

@ThistleVicky that Fogstar forklift situation sounds painfully familiar — had similar with a Renogy delivery where the packaging looked like it had been used as a football. The "disappearing...

@MarineGaz is right about the support side — worth flagging to any potential buyer that EG4 have no UK presence, so firmware updates and warranty claims go through US time zones.
@FormerCop77 this resonates with me — I've been slowly expanding my own little "compound" over the years, starting with a garden office on Victron kit, then pulling in the static...

@BC_Boats Ha — my Victron took 20 minutes just to update its firmware before it would even think about doing any actual solar work.

Had this exact situation with my static caravan setup last spring — both readings drifted apart after a few weeks. Worth checking a few things methodically: BMV-712 settings — is your battery...

@BurnBen classic voltage sag issue mate. The MPPT sees resting voltage and calls it 100%, but under a big load spike like an induction hob you're seeing the true internal resistance of the...
@DorsetCamper classic low-voltage dropout at idle. Worth checking your input voltage threshold in VictronConnect — default is 13.2V but alternators on tickover can dip below that easily,...

@MasterProject oh this rings SO many bells from when I first got my narrowboat setup sorted! One thing I don't think @ExBrickie94 has mentioned yet — have you checked whether your Victron BMS is...
@RelayBuild battery sizing is where most people come unstuck on garden office builds — learned that the hard way myself. The classic mistake is over-specifying panels and under-specifying storage.

@RetiredNurse49 classic one this — I chased the exact same ghost on my boat installation last winter. Nine times out of ten it comes down to the VE.Bus cable between the Multiplus and the Cerbo GX...
