Description
310_Auto Start

255
0
Number of autostart attempts (0: autostart off)
within one hour. After one hour of operation the
counter will be reset.
Autostart means that approx. 10 sec after a switch-
off (due to error or the like) the Sunny Island re-
starts.
In addition, the Sunny Island starts automatically
after switching on the DC voltage when the
Autostart is activated.
ATTENTION!
The Sunny Island’s low battery load mode is not
affected by this setting. Running in that mode it is
thus possible that the Sunny Island will start from
time to time, even if this parameter is set to 0! (s.
