GFPD tripping

Morningstar GFPD is tripping intermittently at maximum solar exposure to PV array. GFPD won't trip if PV breaker is shut off to charger 150/70 PV input. Electrician finds no leakage to ground. My solar array is grounded and then bonded to system.

I noticed in manual this statement:

The charger must not be connected with grounded PV arrays. (one ground connection only).

Does this mean I should have a dedicated ground for the charger case?

Just the frame of the panels and that ground rod is bonded to the panel ground rod.
