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...

The maths on this one is brutal. A 12m² office losing heat through walls, roof and floor needs roughly 3–5kW on a cold day just to maintain 18°C.

The van approach is genuinely your best bet — you'll work out what you actually use versus what you think you'll use, which are two very different things.

The lads have covered the definition, but there's a critical practical aspect for static caravans that deserves emphasis: depth of discharge (DoD). Lithium batteries (LiFePO₄) can safely cycle...

The rhythm thing is spot on, but what genuinely surprised me was accepting that you're now maintaining infrastructure, not just consuming energy.

The efficiency gains alone make it worth the jump. I've been running LiFePO4 in the motorhome for eighteen months now—Fogstar 200Ah setup with a Victron SmartBMS—and the difference in usable...
