I just updated my Quattro's to the v502 firmware. When going through the normal sequence of VEConfigure'ing them to re-enable charging after the update, I noticed that my battery settings are got scrambled. They're showing what looks like AGM settings, while I had it configured for SmartLithium's.
I went ahead and VEConfigure'd without changing it, just to make sure the firmware update went OK. That went fine. Then I went back to fix the battery settings. I set them all back to the correct settings for my 24V SmartLithium system, but when I VEConfigure'd that version in, the Quattro's now sound a low-DC-voltage alarm and won't start up as inverters. The DC input low shutdown shows in VEConfigure as 18.6V, and my batteries are sitting nicely at 26.53V, so I have no idea what's gone wrong. Is my config horrible scrambled now?
