The charging cutoff below 0°C is indeed the bottleneck, but it's worth distinguishing between charging and discharging.

The thread's already highlighted the kettle/microwave elephant in the room, which is fair. What I'd add from my narrowboat experience is that inverter/charger combos need to handle your actual...

The adhesive prep is absolutely critical—@RetiredPlumber's spot on there. I learned this the hard way on my motorhome setup. What nobody mentions enough: temperature matters massively.

Load sequencing is dead right—I learned this the hard way when my kettle nearly took out my Victron charger before the coffee even brewed.

Spot on about the matching, but I'd add something I learned the hard way on my motorhome setup: balancing isn't just about specs, it's about state of charge (SOC) when you connect them. I made the...

Reckon there's a practical angle everyone's dancing around though—it's the maintenance mindset shift. When you're grid-connected, things just work until they don't. Off-grid?

Matching's crucial but don't sleep on the wiring either. I've got two 200Ah LiFePO4s in parallel on my static caravan and used proper 35mm² cable with equal lengths to each cell — even a few...

Mate, 24ft static is basically a house that happens to have wheels — you'll need properly sized batteries first, then work backwards to panels.

@OffGridMax has nailed the ventilation bit — learnt that lesson the hard way myself. My 150/100 sits in a cramped locker on the boat, and I was getting thermal throttling until I cut some ducting...

Mate, the real challenge is accepting that your carefully calculated 10kWh battery bank somehow needs to power the garden office, the caravan fridge, AND your partner's hair straightener...

The cable gauge obsession is justified though—I've seen too many systems running warm cables and wondering why their voltage is dropping to 10V at the inverter.

Had this exact nightmare on my narrowboat. Ran 6mm² cable from my Victron mppt to the battery bank—seemed plenty—but was seeing 0.8V drop under full charge current.

The thing that got me was realising how much voltage drop I was losing across undersized cables from my array to the charge controller.

Absolutely mate, cable sizing bites you hard when you get it wrong. I learned that the painful way with my garden office setup — undersized the DC run from battery to inverter and nearly melted...

Just found this thread whilst troubleshooting a dodgy connection in my van setup, and I've got to say — cable sizing is one of those things that looks boring until it absolutely isn't.

@SunnyFisher cable management is honestly half the battle. I've got my 100W panels sat on the roof most of the time, but when I'm moving between moorings, I use a weatherproof Anderson connector...

Been through this twice now — once in the motorhome, once setting up a narrowboat. The honest truth?
Boxer Camper in Solar Panels & Controllers 1 year ago thumb_up 1
Honestly, what's your actual cable run? That's the key bit everyone's dancing around. I've got a 2000W Victron on my boat and learned the hard way — 10mm² works fine if you're talking under a...

The peaking point @TracyAllen mentions is crucial — I learned this the hard way with my narrowboat setup.

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...
