I have a permanent shore-power connection.
Yesterday I updated the firmware on my BMV-700 to the latest version with a subsequent reboot of the Quattro. Everything appeared to come-up normally - LEDs as expected, BMV display normal, no error messages on the GX display.
A few hours later I noticed that my battery SOC was down and that the BMV-700 was accurately displaying the voltage and current of a now discharging battery bank. The Quattro BULK LED was lit, but the system was not outputting a corresponding charge voltage. Fuses and connections to the main busbar are all good and shunt connections are all good. A meter check on the battery bank corresponds exactly to the reading on the BMV. AC functions (inverter and pass-thru) are all normal.
My suspicion is that the BMV firmware update is a red-herring and that what I am seeing is a failure of the Quattro charger hardware, but I thought I would check here just in case anyone has had a similar experience.
All thoughts welcome.
