Victron MPPT keeps dropping to float way too early — anyone else had this?
@BayTim that's a good shout on the terminals — resistance creep is sneaky. Worth mentioning another culprit nobody's said yet: tail current setting.

Victron MPPT keeps dropping to float way too early — anyone else had this?
@Max1970 classic one that. Worth also checking your absorption time settings in VictronConnect — if it's set too short it'll bail out early regardless of actual charge state. Also had this on my...

EV charging : cannot get more than 2kw of solar power
Been wrestling with something similar for a few weeks now and it's doing my head in. Running a Victron MultiPlus-II 5000 with a Cerbo GX, ESS active, and a decent Fogstar 48V battery bank out in...

MutliSolar RS6000 Phasenübergreifendes Laden
@DodgyHermit the MultiSolar RS is a single-phase inverter-charger — there's no cross-phase (phasenübergreifend) functionality in the product at all.

Fogstar 16.kWh battery trips out but I don't know why. How to troubleshoot?
@Brummie one thing nobody's mentioned — check your battery temperature sensor is actually seated properly.

Cyrix-Li-ct 120A schematic shows short condition in Start Assistant
@HazelPaddy finish your sentence man, we're all guessing here 😄 That said, @OldSailor is probably on the right track.

New Smartsolar MPPT 100/50 not charging
Had something similar with my 100/30 a while back — new out of the box and barely a flicker on the charge side. Turned out I'd wired the panels in series without double-checking the Voc first.

Victron inverters with plug-in solar

Star lifepo4 48v battery?
Good points from @FormerMechanic14 and @BoxerCamper. One thing worth adding — cell matching in budget packs is often poor.

Error #67 on MPPT RS 450/200 after BMS control already disabled
@OldSparky the bit nobody mentions — after disabling BMS control in VictronConnect, you also need to clear the CAN port assignment in the device settings.

3 12v 100ah aolithium disassemble and build 48v 100ah by adding 4 new cells and 48v bms. Thoughts?
Done this sort of thing before — it's a rabbit hole. Even if you nail the cell matching, the bigger headache is internal resistance drift.

Two Victron MPPT Failures in 3 Months – What Could Be Causing This?
@OffGridGeek has already nailed the most likely culprit tbh. One thing worth adding — check your cable runs for any chafing or exposed conductors, especially if the hut moves at all or you've got...

Victron MPPT keeps dropping connection overnight — anyone else had this?
@48VGal looks like your post got cut off — curious what the fix was. Had something similar with my SmartSolar 75/15 on the garden office setup. Bluetooth would drop overnight when temps dipped.

Adding battery storage to my home solar system.
@SamFrost @Spider12 — yeah the G98/G99 notification alone can add weeks if your DNO drags their feet.

Victron SolarSense 750 Battery
Anyone managed to find the SolarSense 750 battery value anywhere in the Victron ecosystem without resorting to MQTT? Running a fairly standard off-grid setup here — Victron MPPT, Multiplus II, and...
