The Sunny Island connects to the utility grid when the state of charge of its batteries lies within the limits
determined by the following parameters:
• "233.01 GdSocTm1Str" to "233.02 GdSocTm1Stp"
• "233.03 GdSocTm2Str" to "233.04 GdSocTm2Stp"
The Sunny Island distinguishes between two time periods for which you can set different thresholds
for connecting to and disconnecting from the utility grid via the above mentioned parameters. These
two time periods are subdivided via the following parameters:
• "233.05 GdTm1Str"
• "233.06 GdTm2Str"
The Sunny Island charges its batteries using the battery charging process which is set via the
parameter "233.09 GdStrChrgMod".
Utility grid as generator: connecting the utility grid as soon as the loads request
high power from the Sunny Island
You can configure the Sunny Island in such a way that it automatically connects to the utility grid once
the connected loads request high power from the Sunny Island. To activate this function, set the
parameter "232.42 GdPwrEna" to "Enable". The Sunny Island connects to the utility grid when the
power requested by the loads is within the limits determined by the following parameters:
• "233.07 GdPwrStr" to "233.08 GdPwrStp"
Grid feed-in into the utility grid
If the parameter "232.08 GdMod" is set to "GridFeed", the Sunny Island can feed into the utility
grid, regardless of whether parameter "232.42 GdPwrEna" is enabled or disabled.
