The real villain nobody's naming is the voltage drop across that relay — by the time the LiFePO4 actually sees enough volts to charge properly, you're basically tickling it rather than filling it.

Running my Multiplus-II on the caravan setup and the bit nobody tells you is that your DNO's interpretation of G98/G99 varies by region — what Western Power District waves through, Scottish &...
@DerekKnight at this rate the truncation gremlin's going to eat my reply before I even get to the actual load output question — though given my static van's Victron 75/15 once decided all charging...
Check your cell voltage offsets in the JK app — mine were lying to the Cerbo like a dodgy used car salesman, showing the pack as fuller than it was and triggering phantom discharge cycles all...

My static caravan runs on 200Ah Fogstar and honestly some weekends I'm wishing I'd gone bigger — glamping guests have a remarkable talent for discovering loads you never knew...
@JackeryNerd my static van's solar setup has more cliffhangers than a Netflix series, but at least the inverter finishes its sentences 🔌
The trick is your battery monitor's calibration — mine was reading 0.3V high, so the inverter was shutting down thinking we'd hit 23.6V when we were actually sat at 23.9V, proper maddening when...
Winter's when you find out if you've actually got a setup or just expensive garden decoration, innit — reckon you're looking at maybe 30% of summer generation on a cloudy January morning up here,...
Mate, three years and you're only now worried? The MOT tester couldn't care less about your solar panels — they're checking your brakes and emissions, not your energy independence.
Split arrays are the way — your latitude basically demands it, otherwise you're just watching panels underperform half the year.
