Inverter Operation

12 Inverter Operation

12.1 Sleep Mode

Using the "270.07 SleepEna" parameter (when set to Enable) allows sleep mode to be
activated in 1-phase grids. With sleep mode activated, the master can switch off the
slaves as long as the power value allows this.
The values in the Sunny Island 5048 for connecting and disconnecting are set at
the factory (optimized to the efficiency).

12.2 Time-controlled Operation

The Sunny Island 5048 can be time-control operated using a timer function (functions
like a timer) and supplies power at the planned time using this function.
To do so, you must activate this function using the "#410.03 InvTmOpEna" parameter.
Using the "#410.04 InvTmOpStrDt" parameter, you specify the start date and using the
"#410.05 InvTmOpStrTm" parameter, you specify the start time. Using the "#410.06
InvTmOpRnDur" parameter, you define the running time and using the "#410.07
InvTmOpCyc" parameter, you can set whether the function is performed once, daily or
weekly until or from the specified time (date and time).

12.3 Overload and Short-circuit Behavior

The Sunny Island 5048 can be temporarily operated under overload conditions. It can
also supply short-circuit currents.
In case of overload, the Sunny Island 5048 supplies an output of 6500 W for
30 minutes and can supply 7200 W for 5 minutes. The device can even supply
8400 W of output power for one minute.
If a short circuit occurs, the Sunny Island 5048 provides current of max. 100 A (for
100 ms). This is sufficient to trigger commercial 16 A B-type circuit breakers.

12.4 Device Faults and Autostart

If a critical fault or occurs, the Sunny Island 5048 automatically shuts down and
displays the reason on the display. If the autostart function ("#270.01 AutoStr"
parameter) is activated, the Sunny Island 5048 can automatically confirm the error,
where applicable, and can restart on its own. If the fault remains, the Sunny Island
5048 cannot be started.
If the autostart meter has counted down to 0, the Sunny Island 5048 waits for
10 minutes before trying to automatically restart again.
