I recently upgraded the firmware on my SPF 3000TL LVM 48P which resulted in total loss of MPPT solar charging.
Prior to upgrading solar charging worked fine; PV icon would show on the display screen and PV would power loads and charge batteries. Afterward no PV icon on display; no charging.
Checked at the PV input terminals and proper voltage and current available; the invert just doesn't seem to recognize that PV is present.
Also noticed that the screen which displays the firmware version for the secondary CPU is now showing 000 000 00 and prior to flashing was 002 518 03 . No idea of this is related to the problem or not.
Could flashing the firmware have fired the MPPT board? Seems unlikely as its the control board that is being flashed, but I don't know?
Anyone else run into this and any ideas on how to troubleshoot/ repair.
