SMA STP 15000TL - Manual (Page 12)

Position Explanation
G Electronic Solar Switch (ESS)
The ESS and the DC connectors together form a DC load-break switch. When
plugged in, the ESS forms a conductive path between the PV array and the inverter.
Removing the ESS interrupts the DC electric circuit and removing all DC connectors
disconnects the PV array completely from the inverter.
