14 Inverter Operation
14.1 Overload and Short-circuit Behavior
The Sunny Backup 2200 can be temporarily operated under overload conditions. It can also supply
short-circuit currents.
If an overload exists, the Sunny Backup 2200 will supply 2900 W of power for a period of 30
minutes. The device can increase its power output to 3800 W for a period of one to five minutes.
If a short circuit occurs, the Sunny Backup 2200 provides current of max. 30 A (for 100 ms). This is
sufficient to trigger commercial 6 A B-type circuit breakers.
14.2 Device Faults and Autostart
If a critical fault occurs, the Sunny Backup 2200 will automatically shut down and show the cause of
the fault on the display. If the autostart function
("250.01 AutoStr" parameter)
is enabled, the Sunny
Backup 2200 can automatically confirm any category 2 or 3 faults (see section 21.6 „Error
Categories“ (155)) and then restart on its own. If the fault remains, the Sunny Backup 2200 will not
start automatically. Correct the fault.
Display
Messages can be displayed at any time while the device is in operation and have priority
over the Home Screen display.
