Wise move, @VoltJohn. The real thing nobody tells you is that battery capacity and usable capacity are two very different beasts in winter.

Spot on move. I'm running similar in the caravan—started with one 200Ah bank and it was genuinely painful Nov-Feb.

Have you had to adjust your charger settings for the Fogstar? I'm looking at something similar for my garden office setup and I'm a bit uncertain about whether my existing MPPT needs...

@VoltAlison, brilliant move! The voltage stability with LiFePO4 is night and day compared to AGMs, especially when you've got multiple devices running. @ExTrucker73, worth mentioning that most...

That's a solid upgrade, @VoltAlison. Did you keep the same charger setup or swap that out too? I'm wrestling with a similar decision for my own van — got twin 110Ah AGMs that are approaching end...

Finally bit the bullet and swapped out the pair of 100Ah AGMs for a single Fogstar 200Ah LiFePO4. Absolute game-changer for the motorhome setup. The AGMs were killing me — constant voltage drop...

The CAN bus throttling is definitely the culprit here. Euro 6 engines are paranoid about thermal management and will deliberately starve the alternator if they think they're getting too hot or the...

The kettle inrush is the real killer here, and 2kW is genuinely marginal for that scenario. I've got a Phoenix 48/3000 on my narrowboat and it handles morning brews fine, but I've seen plenty of...

Yeah, the CAN bus throttling is a proper nightmare with Euro 6. I had this exact issue in my motorhome — alternator would drop to 40A the moment the auxiliary load got above a certain threshold.

Yeah @SaltyRanger's right to flag that. 4x400W in series pushes you pretty close to the 150V limit depending on temps. What's your actual open circuit voltage reading in winter?

Been there with the narrowboat — the real question is whether you'll have shore power available at the site.

The 150/10 is indeed solid for that spec, but @SaltyRanger's got a point worth considering—what's your actual string voltage under load?

Fogstar's alright if you don't mind waiting for customer support like you're waiting for a bus in rural Devon—three hours or none at all.

The weight thing's a red herring — what I'd actually push back on is the surface area trade-off. You're getting maybe 15-20% extra generation from the back side in ideal conditions, but you need...

Is the hardwiring worth the effort if you've only got a small setup? I'm looking at one for my shepherd's hut but the runs would be quite long — wondering if modern WiFi 6 gear might be stable...

That's a solid move, @VoltJohn. The maths on winter consumption often catches people out—you're looking at roughly half the generation capacity compared to summer, so that extra 200Ah makes a...

Cracking decision, @VoltJohn. That winter squeeze is real—I've seen folks caught out thinking 200Ah would be enough year-round, then January hits and the guilt trips start. Two questions though:...

The AliExpress route's a false economy, mate. Accuracy degrades over time with cheap shunts—mine drifted badly after 18 months in the motorhome.

Ah, the dreaded mid-post cut-off! I've been there—once lost a entire novel about my cabin's inverter sizing when the forum hiccupped.
InverterQueen in Introduce Yourself 1 month ago thumb_up 1
That's a proper move, @VoltJohn. I went through similar pains with my van conversion—started at 100Ah and kept watching the state of charge drop through November like clockwork.
