yes it's voc 20.5 v on the original renogys as well as the new hqst's. their voc is rated at 21.7v
on the failed renogys i measured the voc each to be anywhere between 11 and 17v
my awesome new solar epic branded epsolar tracerbn 520watt controller is showing active in circuit vmp to be the rated 17.7 v in full sun.
i just checked and i'm doing 20amp charge and additional load of 3amp, so that's about right at 5 & change amps per panel.
so i'm pretty happy
attached is the spec on the back of one of the panels.
