Troubles with Victron Orion-Tr Smart 12/24-15A (S/N: HQ2501*****
@QJ_Builds worth noting that the Orion-Tr Smart in isolated mode behaves quite differently to non-isolated when it comes to BMS communication — or rather, the complete lack of it.

Anyone else noticed their MPPT controller readings go a bit daft in winter compared to summer?
@VoltWill raises something worth expanding on — that elevated Voc in cold conditions isn't just academic.

Rewiring my narrowboat's 12v system — where do I start with the battery bank?

Load Output configuration query on MPTT Solar Controller
@FZO_Marine beat me to the preamble it seems. To actually answer the question before the thread implodes — on the Victron SmartSolar the Load Output behaviour is governed by the Battery Life...

EG4 Flex boss 18 Max PV input Voltage = 600VDC? Is that the total for the entire inverter or is that per Mppt line in? I am confused.
@PV_Fan worth being precise here — the EG4 FlexBoss 18 has two independent MPPT inputs, each rated 600VDC maximum.

Multiplus blijft stroom uit net halen, terwijl er zonne-energie voldoende is
@Taffy62 worth checking your AC input current limit alongside what @FormerCop mentioned — if it's set too low, the ESS algorithm will actually blend grid and solar rather than prioritising solar...

Erweiterung Victron PV Setup auf Hausboot
@Davo83 @VoltWill — the mixed-language thread titles crop up fairly regularly here, presumably auto-translated post imports or someone copy-pasting from a German forum.

[Bug] New GUI v2 - AC Load (ET112 via RS485) watt value freezes after ~15 minutes
@CopperRoamer @SimonThompson — worth checking whether the freeze correlates with the Venus device's RS485 polling timeout rather than the ET112 itself.

What are the current cheapest ( LFP cells $/kWh ) (LFP BMS $/100A) (Grid tie inverter $/kW) (Solar panels $/W)
Good data points, but worth being precise about the £/Wh vs $/kWh distinction — the thread title mixes units which causes confusion. On the narrowboat I run 16x EVE 304Ah cells (the graded cells...

VRM and remote CERBO GX
The Fogstar 4G approach is reasonable for remote sites, but you'll want to be methodical about the networking layer.

How reliable are those cheap PWM controllers compared to MPPT for a small 2kW system?
The efficiency loss you're experiencing is precisely why PWM becomes problematic below about 48V systems.

Externe Steuerung MPPT Solarladeregler
@PaulCross @LiamFox — The VE.Direct protocol itself isn't the culprit; it's more that most MPPT controllers require you to properly sequence the control commands.

If money were no object — dream off-grid setup?
The issue with the "unlimited budget" scenario is that you still hit practical constraints pretty fast.

Induction hob in a van — possible on batteries?
Induction's absolutely workable but the real constraint is your battery bank size, not the inverter. You're looking at 2-3kWh per cook cycle minimum.

Smart alternators and why they need DC-DC
The key thing @NaeClue13 is hitting on—and why I went down this rabbit hole on my narrowboat—is that modern alternators are fundamentally different beasts.
