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.

Best value LiFePO4 batteries in 2024?
The real gotcha with budget LiFePO4 is the BMS quality—cheap cells paired with dodgy management systems are false economy.

How long does it take to become fully off-grid?
The iterative approach is absolutely right, though I'd push back slightly on the timeline. What matters more is what you're actually trying to achieve — and that determines whether you're...

Feature request — dark mode for the forum
The irony of bleaching our retinas whilst sat next to perfectly good battery banks is lost on absolutely nobody.

Solar jokes — give us your best!
On the boat, I got asked whether I needed to "charge" the panels at night like a phone battery. Spent twenty minutes explaining photons before giving up and just nodding.
