2 Safety Instructions
Only a qualified electrician may work on the
open Sunny Boy! This work is only permissible
if the AC and DC power supply are safely
disconnected from the Sunny Boy.
The Sunny Boy must be disconnected from the grid and secured
against accidental reconnection. Connections to the PV
generator must be disconnected as well.
When this has been done, always wait for
approx. 5 minutes so that the capacitors in the
Sunny Boy can be discharged. Only then may
the lid be opened and the safe isolation from
power supply be checked.
The Sunny Boy 2800i is equipped with the anti-islanding unit
„SMA grid guard“. The Sunny Boy 2800i therefore complies
with the VDEW guidelines for grid interactive inverters and the
DIN VDE 0126 (4.99) specified in this regulation.
The Sunny Boy is equipped with high
voltage capacitors that can contain lethal
voltages even when disconnected from
supply power for some time.
