Spot on about inrush current, @LiFePO4Nerd. I've got a Victron 3000VA in my setup and it handles it fine, but I've seen people use undersized pure sine units and wonder why their compressor fridge...

Shadow mapping is crucial — @HollyGazer's spot on there. I'd add that winter sun angle in the Cotswolds is brutal; you're looking at maybe 15° elevation in December.

The kettle + microwave combo is genuinely brutal — you're looking at 3kW+ easily. A 1000W pure sine won't touch it, you'll just get brownouts and tripped breakers. For a static caravan, I'd lean...

The real issue nobody's mentioned yet is the charge curve itself. Car alternators are designed to top up a car battery that's already 80%+ charged — they're rubbish at low-state charging, which is...

Usable capacity's the thing nobody talks about until they're six months in and wondering why the system cuts out at 20% SOC.

State of Charge - basically how full your battery is, expressed as a percentage. 0% is flat, 100% is full. Why it matters for a static caravan? Depth of Discharge (DoD).

Brilliant that you're thinking about this early on! The garden office setup can actually be one of the simpler off-grid installs if you're pragmatic about your power needs. Key thing I'd mention —...

Winter minimum is spot on, but also nail down your actual usage pattern first. Are you working full-time from there year-round, or mostly spring through autumn?

Great timing catching this before you're too deep in the planning! Garden offices are brilliant for off-grid setups — loads of people on here have done similar. First thing: how much power are you...
