Hi, We have just upgraded our Quattro 12/5000/220-2x75 from v481 firmware to v510 fireware to install Sustain support for a solar array. This all worked without issue, however is was noted that although the float voltage was manually set to 13.80v as previously the float voltage displayed was 13.35v? Now when the sun goes down at around 20.00hrs the SmartShunt 1000A (firmware v4.14) and the 3 X SmartSolar MPPT VE.Can 150/70 rev2 (firmware v3.13) disappear from the Cerbro GX and remote consol/VRM. The Quattro monitors the DC voltage and Sustains charging at 13.35v. All products say when checking firmware that they are upto date. We have tried with and without sustain mode, this makes no difference with the issue. Is this a problem with v510 firmware for the Quattro as it was working without issue previously? Any advice would be much appreciated, thanks.
