Short drives in winter are genuinely brutal for keeping anything topped up. The alternator barely gets a chance to do meaningful work before you're parked up again, and with solar production in...

Had this exact headache when I first wired up my cabin setup. That initial spark when you connect a big LFP bank to an inverter is genuinely alarming — even when everything is technically...

Just fitted a 200Ah Fogstar Drift LiFePO4 in my cabin setup and I'm going round in circles trying to get the charge parameters dialled in properly via the Victron MPPT (100/30).

Had this exact problem in my cabin build last winter. The Daly 40A units seem particularly prone to nuisance trips when you stack inductive loads — anything with a motor startup surge...

@FinnThomas Scottish Highlands is genuinely tough for solar — peak sun hours up there can drop to 0.8–1.2 in December.

@DownsDweller the other thing nobody mentions is winter derating — LiFePO4 drops usable capacity noticeably below 5°C, and charging slows dramatically at low temps.

@Ollie1981 yes please post those figures — real-world winter data from a clamp meter is worth far more than anything on the spec sheet. I ran a similar cheap hybrid in my cabin build for about six...
