Mystery AC stray voltage on PV wires/frames
The PV input terminals to AIO HF inverter are riding on top of a 60Hz 250v square wave (for a 120vac HF AIO inverter). This is why you must use double pole breakers to PV pos and neg wires on these inverters. If PV panels have any leakage resistance between their PV wires and frame of PV panels you will get some leakage from AC square wave.

RCD keeps tripping in rainy weather since having PV system installed
The technician is incorrect. It is almost certain your PV inverter is transformerless, meaning there is no isolation between the grid and the PV panels. The result is PV leakage currents can indeed trip an RCD though inverters are supposed to check for and fault if such leakage exists though this feature can be disabled.
