It has been noted on the other forums that a voltage can build up on the frame (a minute leakage from the panels or just pure static electricity). Whilst not having the frame earthed is nothing unusual, an intermittent connection between the frame and earth could cause pulses of power to flow which could, theoretically, cause the RCBO to trip.

Why do solar panels leak?
The temperature and pressure-relief valve in the solar panels might start to leak if it has become damaged. Excessive pressure in the panels may also be the cause of a leak. Pipe fittings can also come loose and create leaks. The circulating pump ensures that water travels successfully around the system.
Why does the photovoltaic system generate leakage current?
Leakage current of the photovoltaic system, which is also known as the square matrix residual current, is essentially a kind of common mode current. The cause is that there is parasitic capacitance between the photovoltaic system and the earth.
Does leakage current affect solar inverter?
In addition, leak current can also electrify the solar inverter casing, thus threatening physical safety. Standard and detection of leakage current
What type of current sensor is required for photovoltaic leakage?
And it has an extremely high precision requirement, a special current sensor is required. The photovoltaic standard stipulates that for the detection of photovoltaic leakage current, Type B, that is, a current sensor capable of measuring both AC and DC leakage currents, must be used.
