The Sunny Boy pushes the voltage from the PV-modules to the voltage with the
maximum output power.
•
„Constant Voltage"-operation
The voltage from the PV-modules can be set to a fixed value. This value is transmit-
ted to the Sunny Boy with the Sunny Boy Control or with the Sunny Data software
(The parameter is "V-Konst").
