Also, it now seems very unlikely that the ISS circuitry is to blame. It is a brand new circuit board from Scaled Instruments. Since it is behaving exactly the same way as my old ISS circuit board, the cause has to be somewhere else. Doesn''t that leave only the sensors or the solar panel as the possible culprits? Thanks for your reply though.

I have recently encountered multiple failures of the Simplicity board on the York 3 to 6 ton package rooftop units (Sunline). This has been happening on many different jobs with the same units. The symptom is that the blower will not come on, even if the thermostat is set to fan "on". This causes the heat to lock out on high limit, resulting in a "no heat" service call.
Inverter failure can be caused by problems with the inverter itself (like worn out capacitors), problems with some other parts of the solar PV system (like the panels), and even by problems with elements outside the system (like grid voltage disturbances). An inverter failure is when the inverter develops faults that cause improper functioning.

The replacement MPPT power board, and the remaining good boards in the inverter, all have a conformal coating, so I''m leaning towards an internal board fault being the cause of the failure at this point.
