Solar Panel Voc-MPPT?
Wondering if there is any relationship between measured Voc and MPPT performance with a 24v panel. My 12v panel has a Voc rating of 21.9 and Isc of 8.2, but I often see 8.2ish when Voc is only 20....

Amps into the battery are important since this is charge, but its hard to quantify actual performance since there are so many dynamic variables for any given day.
I just let my meter/monitor do its thing and try to keep my usage at a reasonable % of my usable capacity.
This means LED lighting and high efficiency/low power appliance upgrades are needed to keep the solar panels, controller, and battery bank operating well within their design limits.
Though you guys do seem to be having fun trying to herd all of the operational variables into a cohesive result...
