<div><br> </div> <div>Snoozing of course means that there is not enough PV input power to do any useful charging and to wait another 5 minutes</div> <div>and try again.

The tech the distributor sent out did miss some inverter adjustments (LBCO and such), but got all the high side settings and pulled the temp sensor.. the zorched battery terminals were from someone the Homo hired to install/ commission the batteries.. Also discovered that although equipment ground and neutral on the ac side was grounded, it does not appear the DC Neg. buss was grounded.. They are using an older OB green steel mounting setup.. As for OB Tech. I'm thinking most of them have forgotten more than I'll ever know.. But as we all know, some are not above making things up..

The customer complained the system would go dark within a few min. of the batt indicator light going yellow.. From what I've gathered so far the BMS of the batteries is shutting down.. The distributor sent out one of their techs, but it looks like they missed a few adjustments.. The biggie is their CC (OB FM60) went into snooze mode within a day of being connected to these guys, and now OB tells me the CC lost it's FETs and that's pretty common with NiFePO4 BMS.. also when the tech came out to commission the bank, one of the terminals on a battery melted and another distorted.. the customer has a few more days to accept the bank, I'm thinking send them back..
