Product Description
4.1 SMA Grid Gate
The SMA Grid Gate is an external grid and plant protection for use in Italy. It interrupts the connection
between the power generation plant and the electricity grid in the event of disturbances in the voltage
or frequency by controlling up to two section switches. The number of section switches depends on
the plant power. In plants of between 6 kW and 20 kW, disconnection from the electricity grid is
performed via one section switch. In plants of over 20 kW, two section switches are required.

The SMA Grid Gate monitors the three line conductors from the electricity grid for disturbances in the
voltage and frequency. If the lower limit is not met or the upper limit is exceeded, the SMA Grid Gate
disconnects the power generation plant from the electricity grid by opening two section switches.
