Connecting The Pv Array (Dc) - SMA SUNNY MINI CENTRAL 4600A Installation Manual

SMA Solar Technology AG
5.4.4 Connecting the PV Array (DC)
DANGER!
Danger to life due to high voltages in the inverter.
• Before connecting the PV array, ensure that the miniature circuit‑breaker is switched
off.
NOTICE!
Excessive voltages can destroy the measuring device.
• Only use measuring devices with a DC input voltage range up to at least 1 000 V.
1. Disconnect the miniature circuit‑breaker and secure against reconnection.
2. Pull the Electronic Solar Switch downward, slightly
towards the wall.
3. Check the connection cable of the PV modules for
correct polarity and make sure that the maximum
input voltage of the inverter is not exceeded.
At an ambient temperature above 10°C, the
open‑circuit voltage of the PV modules must not be
more than 90% of the maximum inverter input
voltage.
Otherwise, check the plant design and the
PV module connection. If this is not done, the
maximum inverter input voltage can be exceeded
at low ambient temperatures.
