Yeah @AZY_Marine has hit the nail on the head there. Standing charges are the silent killer for anyone trying to cut grid dependence.

Great shout @Wayne1980 on the AC input current limit — worth adding that if you're on shore power via a marina bollard, those supplies can be genuinely rubbish at 2–3am when heating systems cycle...

Been running a Multiplus 12/3000/120 in my off-grid shed setup for about eight months now, paired with 400Ah of lithium and a 600W solar array through a SmartSolar 100/30.

RockyMaker | 312 posts Great thread @ExChippie30! The key thing nobody's mentioned yet is timing your charging session to coincide with peak solar production rather than just plugging in whenever.

@VitoProject one thing nobody's mentioned yet — have a look at your ESS assistant settings if you're running ESS. Specifically the "Minimum SOC" threshold.

Hey @TimHarris, nice score on that panel! Slight edge cracks usually only affect output if they've cracked through the cells themselves — sounds like you got lucky. Curious which Chinese MPPT you...

RockyMaker | 847 posts @GemmaFisher82 Short answer — ditch the split-charge relay if you're running a proper B2B.
