12.1 Sunny Tripower is Beeping

Electric shock due to electric arc when pulling out the DC connectors
Death or serious burns
The Sunny Tripower has short-circuited the PV array to avoid reverse currents.
• Strictly adhere to the procedure as described in the following table.
Cause
Installation fault (reverse
polarity of a string or
connection of strings with
different numbers of modules)
OR
Reverse current in the PV
plant (defective string)
The Sunny Tripower
short-circuits the PV array to
avoid reverse currents through
individual strings. Depending
on the level of irradiation, this
could trigger high current flows.
However, the PV array and the
Sunny Tripower are in a safe
state.

Measure
• On no account pull the Electronic
Solar Switch or DC connectors out.
Wait until the Sunny Tripower stops
beeping (after dark).
If you pull the DC connectors, there is a
risk of electric arcing.
• With an open Sunny Tripower: Prior to
leaving the Sunny Tripower, install
contact protection (e.g., fence) and
moisture protection (e.g., tarpaulin).
• Wait until dark before pulling out the
Electronic Solar Switch and all DC
connectors, and only then eliminate
any errors (reversed-pole or defective
string).
• Contact the SMA Service Line
(see Section 16 "Contact", page 126)
