2 inputs at a time are grouped together using an integrated relay and are
activated/deactivated together. One LED indicator displays the string status
of 2 strings. For example, if there are only 4 strings, only the LED indicators
(13) and (14) are in operation.
The LED indicators light up or flash green or red. Note the following:
Direct solar irradiation can make the LED indicators difficult to read.
