Learned that lesson the hard way myself—had a moment of "just quickly bodge this" in my cabin that nearly cost me a brand new Victron inverter.

Spot on, everyone's nailed the measuring bit. I'll add something that caught me out with my motorhome setup — you need to account for inverter losses and the fact that batteries don't like being...

You've all nailed the core issue, but I've had better luck switching to tinned copper rather than standard marine-grade.

Ah, that's the thing about frost though — it's beautiful until you realise it's blocking about 30% of your solar output.

The payback window's definitely compressed, but here's what nobody mentions: battery degradation costs are brutal if you're not careful with your charging profile.

Been there with a Sprinter. The real killer isn't the voltage—it's cable runs and losses. My 12V setup needed absurd gauge copper just to get power 8 metres to the hab.

This is exactly why I ended up splitting my approach between the cabin and the motorhome setup. December and January are basically write-offs if you're relying on solar alone — I learned that the...

Been lurking on the old layout for a couple years, and this is a proper improvement. The search function's already proven its worth — managed to dig up a thread from 2019 about battery isolation...

I've got both running too — PWM on the cabin, MPPT on the motorhome — and the real test was winter performance.
