Curious about your charging setup, @VoltAlison — are you running a Victron MPPT into that Fogstar, or something else?

Got bifacials on the narrowboat and they're a game-changer when you're against a light-coloured bank, but honestly?

Been down this road with my van conversion setup. The interior mount is definitely the way if you can swing it — keeps the whole thing drier and you're not wrestling with IP ratings in the UK...

Had a similar headache with my van conversion—ended up going Phoenix 48/3000 and honestly, it's been bulletproof for three years now.

The voltage stability is only half the story though — what really matters is the usable capacity. Those AGMs you're ditching were probably only giving you 50% DoD safely, so your effective...

Winter canal positioning is your real enemy here. Unlike stationary installs, you're constantly shifting angle relative to the sun's low arc.

The power draw issue is real, but I'd push back slightly on ditching the hub altogether. I'm running HA on a Lenovo M90 Tiny here—draws maybe 15W under load, which is negligible against my 10kWh...

That's bang on with the winter reality. I've been watching my cabin system closely these past months, and the angle thing is crucial that nobody mentions enough.

Went LiFePO4 in the van last year and never looked back. The voltage stability alone is worth it — AGMs would sag to 11.8V under kettle load, the Fogstar stays flat until it's genuinely low. Fair...

Canal boats and winter sun are like a relationship that needs counselling — technically possible but requiring serious effort and compromise.

We've been running a 400W Fogstar system on our narrowboat for two winters now, and I've got to say the performance drop is... significant.

The winter reality is brutal, and it catches everyone out. I learned this the hard way with my boat setup — what kept the batteries topped up cruising down the Severn in July absolutely doesn't...

Looking at this from an emergency backup angle — have you considered whether you actually need two chargers running simultaneously, or are you after redundancy if one fails? If it's pure capacity...

Interesting thread this. Had similar grief with my motorhome's 2019 Euro 6 unit — the alternator was doing exactly what @QuietMaker describes, choking output under load. Before you go down the...

Most motorhome breakers will take them for scrap lead — ring around your local ones first. If that draws a blank, your council tip takes them free.

Had a pair on my shepherds hut for about eighteen months now. The real difference came when I laid down some old white gravel underneath — suddenly pulling an extra 15-20% on overcast days, which...

Yeah, I'd say skip the hub entirely if you're tight on power. Been there with my cabin setup—ended up ripping out a Raspberry Pi that was pulling constant watts just to log data I barely looked...

Cheers for the thread idea @AnneButler — been eyeing bifacials for my narrowboat setup. My concern is I'm mostly moored on muddy towpaths and occasionally concrete, so I'm wondering whether the...

The kettle inrush thing gets everyone initially, but honestly it's not the full picture here. Yes, you'll see 3-4kW spikes on a decent kettle, but that's milliseconds.

Spot on about the Victron extraction hassle, @OldSailor. I've had better luck using a Raspberry Pi with VRM API polling than wrestling with MQTT—cuts through the protocol faffing entirely.
