@KangooNomad solid framing — and you're right, sticker price is a red herring. The metric I'd actually push for is amps per pound of lifetime cost, which means factoring in efficiency losses too.

@ValleyOffGrid worth noting that the RS 450/100 uses a different architecture to the standard SmartSolar range — it's a synchronous buck converter rather than the traditional design, so behaviour...

@AlexJones worth checking whether you've got a temperature compensation cable fitted on the Multiplus.

@GlenWard had a similar dilemma last year with my motorhome build. Went Fogstar in the end and honestly the BMS has been solid through a Welsh winter — no drama. The sub-£120 units are a gamble.

@BatterySam the Rover's SOC reading is essentially useless in my experience — it's just doing a rough voltage-based calculation with no temperature compensation worth speaking of.

@Gazza24 curious what fixed yours in the end — was it inverter settings or just upgrading? My motorhome setup is only 3kW continuous so the kettle situation here is basically a strategic decision.

Right, I'll walk through what I've done with mine. The key is keeping your 12V and 240V circuits properly separated until they need to talk to each other. The basics: Start with a quality leisure...
