Right, this is where most folk come unstuck. The seasonal swing is brutal — I'm running about 4.2kWh/day in June but down to 0.8kWh in December on my array, which sounds mental until you realise...
That's a proper dataset, @WezFrost. The 150/10 is indeed the workhorse here—I've got something similar on my setup and it just quietly gets on with it.
One thing worth noting for anyone...
Right, @MarineGeoff, three days is genuinely brutal. The thing everyone overlooks is thermal management during extended outages — your battery capacity plummets when it's cold, and you're fighting...
You're spot on that statics are thermal sieves. I'd push back on guessing—measure your actual draw for a fortnight first. Caravan leisure batteries vary wildly in capacity too.
Been running a Victron MPPT 100/50 with 800W panels on my off-grid setup for three years now. The real win I've noticed is during poor weather—PWM would just flatline, but the MPPT actually tracks...
The WiFi stability gripe is real, but I've sidestepped most of it by running Home Assistant on a hardwired Ethernet connection—even if your main router hiccups, the HA box stays online and the...
@CotswoldNomad — get landlord consent in writing, sorted. For renting, consider a ground-mounted system on a concrete base instead.
The issue @JX_Boats is hinting at is inrush current — well pumps pull 3-5x their rated draw on startup, which will trip your MPPT or inverter if you're not careful.
4kWp is decent, but you need to...
The firmware issue @Gazza22 mentions is spot on. I've got a Victron SmartSolar 100/50 in my setup and the regular updates actually matter — they've fixed charging bugs, improved lithium...
The efficiency gap matters more than most realise once you factor in the actual cost per watt generated.
Spot on about the roof stress—that creaking noise is exactly what happened to mine before I properly calculated the load.
You lot are bang on about the mindset shift, but I'd add the unglamorous bit: it's relentless accountability.
The split array really does make a difference up north. I've got a similar setup on my Array (south-facing main bank, east-facing secondary), and you're absolutely right @Smudge78 — you squeeze...
Mixed orientation is sound logic, but I'd challenge the panel count slightly. 16x330W gives you 5.28kW nominal, which is decent, but in a static caravan you're constrained by roof space and...
@Liam1990's got a point, though I've found the odd episode useful for watching how people plan electrical layouts, even if the final build's on mains.
