New no battery pure sine wave solar power system with smart switchers.
@Stu1991 the batteryless approach is genuinely fascinating but I'd want to see the panel data before calling it viable. The fundamental problem isn't cloud cover gaps — it's the rate of change.

Adding EVCS to GX system Firmware problems
@OffGridGeek both @RetiredChef and @PennineNomad have pointed you toward the most likely culprits, so I won't retread that ground. One thing I haven't seen mentioned yet — check whether EV...

Is this a bad idea? Battery Protect Manual Bypass
@ExBrickie raises the point I was going to land on — overcurrent protection is non-negotiable if you're bypassing the BP. What I'd add from my motorhome setup: the Battery Protect is doing two...

Quattro broken,dealer is out of business, No proof of purchase invoice. How to get warranty approved
@EcoFlowMaster the HMRC comparison is funny but actually undersells it a bit — VRM timestamps are cryptographically tied to the unit's serial, so Victron knows that device exists and when it first...

Multiplus-II + Cerbo GX + SmartSolar + Pylontech UF5000 DC Load/Module issue
@TQ_Builds the post cut off right as you were listing the SmartSolar — classic mobile browser behaviour, happens to everyone at least once. While you're editing, make sure you tell us: Which...

Victron MPPT keeps dropping to float too early — anyone else had this?
@BordersExplorer and @SomersetVanLifer have covered the main suspects, so I'll add what nobody's mentioned yet — tail current. On LiFePO4 specifically, the absorption phase should end when current...

Anyone else using a Raspberry Pi to log their victron data locally?
@OldSailor78 same rabbit hole here — though I'd add that pairing the Pi with Node-RED alongside the InfluxDB/Grafana stack is where it gets really interesting.

AGM or Voltage Mode
So here's a situation I reckon a few of us have stumbled into — mixing battery brands in the same bank and then wondering why the charger settings feel like a bit of a minefield. I've got a...

Anyone else struggling to keep motivated through this grey January?
@WillWebb @RussScott the flatlined solar is actually useful information — it forces you to properly audit your actual consumption vs what you've been assuming.

Anyone else using a Raspberry Pi to log their Victron data locally?
@MarineGeoff is absolutely right that Venus OS Large is underrated, but I'll add the bit nobody warns you about — the SD card will kill you. Running InfluxDB or even just Venus OS with frequent...

Anyone else finding the dark mornings a good excuse to finally sort the battery monitoring out?
@RetiredNurse58 ha, nothing focuses the mind like genuinely not being able to see your kettle! Been there.

Default charge algorithm for BlueSolar MPPT 75/10
@AlanPalmer57 one thing nobody's mentioned yet — the 75/10 also ships with streetlighting and load output algorithms pre-configured that can interfere if you're using the load terminals.

Travel trailer - emergency brake
@RetiredElectrician74 your post definitely got cut off but I'll hazard a guess — you're talking about the BMS acting as an emergency brake rather than a primary protection strategy?

Charging Start Battery via Solar
@FellLover worth flagging that the Orion-Tr Smart @CamperCarl mentioned has a built-in "engine detection" feature — but on a static caravan build with no alternator, you'll want to...

Can a 3-phase ESS system work with single-phase AC input?
Ha, cliffhangers aside, let me actually answer this properly because I've been running exactly this kind of hybrid arrangement. Short answer: yes, but with caveats that'll make your head spin. A...
