• On no account disconnect the Electronic Solar Switch or
the DC connectors. Wait until the Sunny Tripower stops
beeping (after dark).
Pulling the DC connectors causes a risk of arcing, since the
Sunny Tripower short-circuits the PV array in order to
prevent reverse currents through individual strings.
Depending on the level of irradiation, this could trigger
current flows. However, the PV array and the
Sunny Tripower are in a safe state.
• Before leaving the Sunny Tripower, install a contact
barrier (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).
The display is showing the
