Non-isolated inverters operate at high frequency.There will be an a.c. component on the d.c. supply.

This is capacitively coupled to the module frames producing an a.c. voltage. While not likely to be

lethal, this electrostatic charge, if not depleted by earthing, could be enough to frighten and possibly

cause a person to fall off the roof.
