Startup - SMA Sunny Boy 1700 Installation Manual

SMA Technologie AG

5.3 Startup

You can start up the Sunny Boy 1700 when
• The lid is securely screwed on the enclosure.
• The AC (mains) cable is connected correctly
• The DC cables (PV strings) are fully connected and the unused DC plug
connectors on the bottom of the enclosure are closed with the protective caps
How to start up the inverter
1. Switch the line circuit breaker to the "on"
position.
2. Now look at the LED display and check the table
on the next page to check whether the Sunny
Boy 1700 is in a fault-free operating status
If the bottom yellow LED flashes four times at intervals of one
second, the grid voltage and the PV generator must be
disconnected from the Sunny Boy 1700 immediately! There is a risk
of damage to the inverter resulting from excessive DC input
voltage.
Check the string voltages again to make sure they are within the limits stated in
section 4.2 "PV generator requirements" (page 15).
If the Sunny Boy still indicates a too high DC voltage even though the voltage is within
the specification contact SMA Technologie AG (see section 10 "Contact"
(page 43)).
