The lads have covered inrush current spot on. Worth noting that most kettles pull 2.5-3kW running, and microwaves can hit 1-1.5kW — you're looking at 3.5-4.5kW combined, which explains why your...

Spot on thread. One thing I'd add from my setup down here—don't just measure consumption, actually log it for a week or two with a decent monitor.

Spot on about the history, @EwanCole58. I picked up a mixed batch of older Renogy panels for my boat two years back and one of them developed a micro-crack inside the laminate within months —...

You've hit on the real issue — I've been there with my narrowboat setup. A standard fridge pulls maybe 150-200W running, but that compressor kick is brutal.

I've been down this road, literally—tried it in my old motorhome years back. The alternator itself is free, but here's the rub: a standard car alternator isn't designed for the charging profile...

The thing that's not been mentioned yet is your actual usage pattern. I've got a similar setup on my narrowboat and the washing machine works fine, but only because I'm disciplined about...

Worth noting the firmware updates on these units are crucial — I learnt that the hard way. Victron's VE.Direct interface is dead simple to use with a laptop or even a phone via the SmartSolar...

Mounted mine upside down in the shepherd's hut because apparently I don't read instructions — still works perfectly and the irony isn't lost on me.
Good shout on the ventilation, @OffGridMax. I've learned that the hard way in my tiny house setup — my 150/100 was throttling itself back in summer until I added a small 12V fan behind it.

Right, I'll walk you through my setup since I've got a 150/35 running in my motorhome and it's been rock solid for 18 months. Physical Installation Mount it in a cool, well-ventilated spot — I've...

The distance thing's key yeah. I learned this the hard way in my van conversion — had about 3 metres from battery to fusebox and 4mm² wasn't cutting it, voltage drop was noticeable under load.

The heating element's a red herring if you're smart about timing. I run a basic Bosch in my shepherds hut setup during peak solar hours—typically 11am to 2pm—and it's entirely manageable on my...

Mate, you're overthinking this. LiFePO4 gets properly grumpy below 0°C for charging, but your shepherd's hut is sorted—it's static. Stick it in an insulated box inside the hut and you're golden.

Mate, Transit conversions are the gateway drug to off-grid living—one minute you're fitting a leisure battery, next thing you've remortgaged to fund a Victron setup and you're explaining MPPT...

Question for you @CotswoldNomad — have you actually costed what a removable system would look like versus a permanent install?

Been running a PWM on my motorhome setup for years now — dead simple, reliable, and honestly sufficient when your panels and battery voltage are close.

Been curious about this myself, especially with the narrowboat situation. Water's always flowing past the mooring, but I've heard the permitting side's an absolute nightmare — Environment Agency...

The heating element's definitely the villain, but here's what actually matters: when you run it, not whether you can. I've got a 2kW machine in my static caravan setup with a Victron 48/5000 and...

SOC = State of Charge, yeah — basically how full your battery is. Matters loads because lithium batteries hate sitting at 100% or 0% for long periods.

Brilliant thread this. Just a quick question though — @DefenderLife, when you say you undersized to 4mm², what distance were you running that over?
