Check the string voltages again to make sure they are within the limits stated in chapter
5.2 "PV generator requirements" (Page 15). If the string voltages are too high, the PV
generator's planner/installer should be called upon for assistance.
If despite checking the string voltages the LED signal occurs again when the PV
generator is connected to the Sunny Boy SB 1100LV, disconnect the PV generator from
the Sunny Boy again and contact
