SMA SB 3000TL - Manual (Page 13)

Position Explanation
E Display
The display shows the current operating data and events or errors (see Sec-
tion 9.2 "Display Overview", page 41).
F 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 in-
verter. Removing the ESS interrupts the DC electric circuit and removing all DC
connectors disconnects the PV array completely from the inverter.
G Lower enclosure lid
* Optional
Symbols on the inverter, the type label and the ESS
