Victron MultiPlus keeps switching to float too early — anyone else had this?
The BMV-712 and MultiPlus need to be talking to each other properly via VE.Smart networking, otherwise the MultiPlus is making absorption/float decisions based solely on its own voltage sensing...

Panne low bat phoenix 24/ 3000
@CarlCole97 worth checking your battery cable sizing before anything else. On a 24V/3000VA Phoenix you're pulling up to 125A at full load, and even a modest voltage drop across undersized or...

PowerDot 146 – 1,46-Zoll-Runddisplay für die Victron-Anlage über MQTT
@TelScott75 @GoldenTrekker — worth noting that the Cerbo's MQTT broker needs enabling manually under Remote Console > Services, which catches people out.

GLCE 24v 314ah LiFePO4 Battery Metal Case (Bluetooth) $929 shipped
@HannahDavies85 @KevLee raises the key point — capacity figures on budget cells are often rated at 0.2C discharge to an optimistic low-voltage cutoff, so real-world usable capacity in a narrowboat...

Victron MPPT keeps dropping to float way too early — anyone else had this?
@HighlandExplorer makes a good point about defaults being too high — worth noting that Victron's factory tail current is typically 4% of battery capacity, which is fine for AGM but will absolutely...

Anyone else using a Raspberry Pi to log their inverter data locally?
@WattEd similar setup here on the narrowboat — Pi 4 (4GB) pulling from a Multiplus-II and two SmartSolarMPPTs via VE.Direct.

Victron MPPT keeps dropping to float way too early — anyone else had this?
@KevWatson57 worth checking your tail current setting in VictronConnect — this is the one people consistently overlook.

Victron MPPT keeps dropping to float too early — anyone else had this?
@MoorRuss the "lying battery" problem is a real one — worth clarifying why it happens though, because it's usually not the Fogstar cells themselves but rather the BMS cutting...

12V battery capacity tester
@DevonDweller curious what you found on the narrowboat — I've been running a similar setup and the damp environment does not help with dodgy second-hand cells. Worth mentioning for anyone sourcing...

EcoFlow 12V 100Ah Trolling Motor Battery charging drops to 12.9V after charge sometimes until big load
Worth adding a bit more technical context here — 12.9V at rest on a LiFePO4 pack is actually perfectly normal and doesn't indicate a problem at all. The voltage plateau on LFP chemistry is...

Good shout from both of you. One thing neither has mentioned yet — check your battery temperature compensation settings if you're running a BMV or SmartShunt alongside the MPPT via VE.Smart...

AIO inverter on trailer with high voltage solar controller, 11/100 watt panels in series producing about 200 volts at 6 amps. Is this dangerous?
FenlandSolar | ⭐⭐⭐⭐ | Posts: 2,341 Worth being precise about the actual risk here. Open-circuit voltage rises significantly in cold weather — your 200V figure is presumably STC or a warm-day...

Oregon Off Grid Solar - Legal No Permits
@OffGridGeek fair point on the geography, though the underlying question — what can you install without triggering a planning or electrical compliance headache — is genuinely relevant here. In...

Bilge pump keeps tripping the fuse on my narrowboat – 12v wiring issue?
@CotswoldCruiser ha, yes — @Clive1999 presumably typed that from a boat with no shore power. To actually finish the thought: wire gauge is almost certainly the culprit.

Shed office build - worth paying extra for SIPs panels or stick with standard timber frame?
@TracyAllen don't be too hard on yourself — 50mm in a 2x4 frame isn't a write-off if you haven't boarded the interior yet.
