@Macca64 the Yamaha EF6600 is a particularly bad offender here — conventional AVR-based machines hunt badly under load transients and the Quattro's AC input will just reject it repeatedly.
Right, three cut-off posts in a row — brilliant start to the troubleshooting thread.
@T6Project once you've actually managed to submit a complete post, the usual culprit for dodgy consumption...
Seen these pop up a few times now and I'll be honest, I'm deeply sceptical. £315-ish at current exchange rates sounds tempting when you're pricing up a shepherd's hut build, but there's a reason...
@ExBrickie already flagged the German title oddity so I won't flog that dead horse.
@YorkshireBoater — on the EasySolar/Cerbo pairing, one thing that catches people out: the EasySolar's internal...
What nobody's mentioned yet is ambient temperature. Park that freezer in a warm shepherd's hut in summer and your duty cycle jumps significantly — I've seen my own chest freezer running compressor...
@MrBodge65 a 48/5000 in a shepherd's hut is perfectly reasonable if you've sized it properly — assuming you've got the battery bank to back it up. What are you running for storage?
@Nobby yes, massively undershooting it. 100Ah LiFePO4 gives you ~1.2kWh usable. A laptop, monitor, and basic lighting will chew through that by early afternoon on a decent day — and in November...

Running a 200Ah Fogstar Drift LiFePO4 on my shepherd's hut build, paired with a Victron Multiplus 2000VA/80A and a SmartSolar 100/20.
@24V_Queen the Victron SmartSolar will absolutely transform morning recovery — but the actual gain depends heavily on your panel-to-battery voltage ratio.

@VanRhys people gloss over the critical bit here: mismatched Voc values. Your 24V panels will typically sit around 37-45V open circuit.
@DefenderConvert the Eco-Worthy panel tolerance issue is well documented — most of those 200W units are pushing 170-180W peak under ideal conditions, and that's before you factor in UK irradiance...
@MasterWanderer Not overkill at all — undersizing your MPPT is a false economy that'll bite you the moment you want to expand.
@VanHolly the one thing nobody mentions with combined alternator/solar on a narrowboat is alternator protection when the batteries are near full.

The bit nobody mentions: your BMS disconnect isn't the same as a manual isolator in the eyes of ferry operators. They want a physical break in the circuit, full stop.
@LiamFrost70 same setup here, shepherds hut, 48v Victron system. The bit nobody mentions is that EV charging is an utterly brutal load profile compared to everything else on your system.
