Backwards polarity is genuinely one of those lessons that sticks with you. The reason it escalates so quickly is that you're essentially creating a direct short across your battery—current flows...
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...
The network instability @T5Wanderer and @ExChippie94 mention is real, but there's a pragmatic workaround most people overlook.
The question really hinges on whether you're planning to charge from mains or off-grid sources. @RussMitchell75 and @Boycie have got the right idea.
For a static caravan, if you've got permanent...
@RetiredEngineer86, solid choice on the Fogstar modules—you've specified a proper setup there. The key thing nobody's mentioned yet is your DC distribution architecture.
Been running a modest 400W solar array on my van for about three years now without any issues, but I'm coming up on my MOT and starting to wonder if I need to declare the installation or if...
Worth noting that recycling centre panels can be a minefield — you've got no warranty, no datasheet, and no way to know if they've been sat in the weather for years degrading.

The real trade-off is degradation rates. Flexibles typically lose 0.8–1% annually versus 0.5% for rigids, so over 10 years that compounds meaningfully.
@BayTim's got the fundamentals spot on. Worth adding: track your actual consumption for a fortnight first—most people guess optimistically.
The elephant in the room here is duty cycle. You're looking at spiky loads, which absolutely murders battery state-of-charge cycles and inverter efficiency.
What you actually need to establish is:...
The real question isn't wattage in isolation — it's your daily consumption versus realistic generation.
@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.
