DazHughes | 203 posts @RussStevens Worth checking whether your shunt is actually rated for continuous current at that 500A figure, or whether that's a peak rating — a lot of the cheap ones are,...

Mine's a Victron SmartSolar 100/30 and it's been playing up since the temperatures dropped here in South Wales.

Hey @DevonCruiser, short answer is yes, absolutely doable. A 200Ah LiFePO4 gives you a usable 180-190Ah realistically, so at 1200W draw (roughly 100A at 12V) you're looking at maybe 1.5-2 hours...

Hey @WezFisher, worth checking whether it's actual capacity loss or just the BMS getting confused by the cold.

@Moorey44 just to add to what @AndyReid mentioned about panel voltage — PWM controllers in general (Wanderer included) work best when your panel voltage is fairly close to your battery voltage.
