Requirements specified by the power supply utility
When operating the photovoltaic unit as
a grid feed system, observe all current
requirements and regulations of your
local power supply utility.
The photovoltaic system must be suita-
ble for operation with the power grid of
your local power supply utility, and any
interference affecting the grid or third
parties must be reliably prevented.
Only approved contractors may connect
the system to the power grid and install
the earthing/surge protection. Agree all
necessary steps in connection with the
supply meter with the relevant power
supply utility.
The photovoltaic system must be accep-
ted by an electrical contractor who will be
responsible to the user and the power
supply utility for its correct installation.
