Warranties from Fronius will remain valid as long as the design rules for the PV system are obeyed.
Design rules:
For successful integration it is mandatory that the maximum PV system voltage must not exceed the maximum
input voltage of the inverter at any time in compliance with the temperature coefficient of the open circuit voltage
(Udc,max).
Furthermore the maximum MPP voltage Umpp,max must not exceed the inverters Umpp,max rating in
compliance with temperature coefficient of MPP voltage (if applicable, otherwise use temperature coefficient of
MPP power).
Fronius declines any responsibility for any direct or indirect damage, injury or losses, arising or resulting from
any malfunction, misuse or defect, apart of the scope of our warranty terms and conditions.
Explicitly Fronius declines any responsibility for damaged modules, optimizers or integral part of before
mentioned, even if caused by Fronius.
Fronius reserves the right, to resign this approval at any time, with immediate effect and without any
information, for example if the technology or device shows disadvantageous effects for inverters or other parts
of the system, or if new features interfere in any way.
