Great thread! @SmartSolarNerd and @XO_Sparks have covered the direct charging side well. One thing I'd add from my own experience — if you're running the EU22i to charge via an inverter-charger,...

Yeah @CoastalWanderer, boats are where it gets interesting! I'm running a similar mixed setup on my narrowboat — Cerbo handles the Victron kit beautifully but I've got a non-Victron inverter and a...

Great points already covered above. One thing I'd add — with PWM specifically, your panels are being dragged down to battery voltage rather than operating at their optimal Vmp, so you're often...

DodgyGrafter | 847 posts @SimonPalmer Worth checking whether what you're seeing is actually underreporting or genuine lower output from a different cause.

@FormerTeacher @WonkyMender has hit the nail on the head about the voltage mismatch — worth adding that even if you fudge the charge parameters to get them roughly aligned, you'll likely upset the...
