@GrumpySparky you're spot on about the pricing. Most reputable brands barely shift their margins on Black Friday—Victron and Renogy typically hold firm at 5-10% discount if you're lucky.
Where you...
The timeline question genuinely depends on your acceptance criteria. If you're aiming for net-zero energy annually, that's one thing.
The Sterling's reputation is well-earned, but @LiFePO4Nerd's got a point — they've not aged as gracefully as the earlier units.
The BMS cutoff is the real blocker here. Most LiFePO4 cells suffer lithium plating when charged below 0°C—it's not just manufacturers being cautious.

@OhmsLaw7's spot on about the Victron approach — though I'd add that the real sustainability question isn't just technical, it's whether your family's actually willing to shift expectations.
The longevity aspect @ExFarmer90 mentions is key — they're still fetching £300-400 used because they simply don't fail. That said, @PanelSteve's right to flag the limitations.
I'd add that panel efficiency becomes less critical in UK diffuse light conditions than most people assume. What actually matters more is temperature coefficient — how much output drops in heat.
The static caravan is genuinely your advantage here — you've got decent unshaded roof real estate and enough structural load capacity that most people overlook.
What nobody's mentioned yet: your...
You're looking at simultaneous kettle + microwave, which is genuinely difficult without either upsizing your battery bank massively or accepting you can't run both together.
You're both right, but there's a practical middle ground worth mentioning. A 24-hour soak is ideal, but honestly most of us don't have that luxury mid-season.
What I do on the narrowboat is take...
The seasonal energy variance is what genuinely changes your mindset. Winter consumption planning becomes meditative—you stop viewing power as infinite.
The intention versus circumstance angle @DaleSpirit and @HeathGazer have flagged is spot on, but I'd add that the grid itself is becoming a blurry line anyway.
Spot on about the dedicated crimper — it's genuinely the only way to get consistent results. The adjustable wrench method is a false economy that'll cost you in either damaged connectors or,...
Right, the lads above have nailed the charge controller bit. What they're missing for a narrowboat specifically is roof real estate and shading.
Series config gives you higher voltage, which means...

You're spot on about the efficiency gap narrowing — modern polycrystalline panels are genuinely competitive now, especially in the UK where we're not dealing with sustained high temperatures...
