The Sunny Island can control ecopower Mini combined heat and power units of the
company VALENTIN Energie- und Umwelttechnik GmbH.
If one or more CHPs are available in the system, the corresponding values must be
set in the menu „PARGRD“ (3+4). The CHP is controlled via the serial RS232 inter-
face COM3 of the Sunny Island.
The menu „BHKW“ (2+5) is primarily used for the display of the CHP´s operating
state. In addition, it can be used for the commissioning of the plant to manually
switch on and off the CHP with special inputs. All inputs are only valid until the menu
is quit. The menu items are:
