I would think you would need to have accessible isolator, like a fireman's switch for high voltage signs, considering these solar panel are capable of producing 1500 VDC. It doesnt make sense having a switch disconnector next to the inverter locked in a garage, outbuilding or inside the house.

Its like mounting a lithium battery below 1.5m in a garage (especially in front ) used to park motor vehicle and people say mounting them in the bedroom is stupid.
If you need to remove the inverter to replace or take for repairs at some stage you would need to be able to ensure that all wiring lying there is safe which is why I would use that particular regulation to ensure that I can lock out
