3. "Stop" Setting
This setting immediately stops the generator, as long as the "24-1 GenControl"
parameter is set to "Direct" or "GenMan".
4. "Run1h" Setting
This parameter setting can be useful when the batteries should be relieved by the
generator for a foreseeable period of time. As soon as the "24-3 GenOperation"
parameter is set to "Run1h", the generator is requested for a period of one hour. The
"Run1h" setting is indicated by a "T" in the display (see section 4.6 "Generator
Request" (page 26)).
After one hour has passed, the Sunny Island 3324/4248 automatically sets the "24-
3 GenOperation" parameter back to "Auto".
5. "Release" Setting
The "Release" setting releases the 20 minute lockout time triggered when the reverse
power limits are exceeded.
The "24-11 PGenReverse" parameter limits the power that may be fed back into the
generator for up to five seconds.
If the reverse power exceeds this value then the generator/grid is disconnected and
the Sunny Island 3324/4248 switches to stand-alone grid operation. The generator
or grid cannot now be reconnected for a period of 20 minutes. Setting the "24-3
GenOperation" parameter to "Release" removes this lockout. After "Release" has
The Sunny Island 3324/4248 can not start the generator and will
not connect an externally started generator if you have switched
it off using the "Stop" setting.
Remember to reset the "24-3 GenOperation" parameter back to
"Auto" if the Sunny Island 3324/4248 should assume control of the
generator.
Please also note that a generator stopped using the "Stop" setting
can also be started by other components in the stand-alone
system. For example, the GenMan independently starts the
generator as soon as the generator starter battery voltage sinks
below a particular value.
Exception:
If "Run1h" was selected from the "Stop" mode, after one hour the Sunny Island
3324/4248 returns to this mode (see also 3. "Stop" Setting).
