Hi
I'm due to have my Solar PV system installed in about 10 days time, I've just been advised that the Fronius IG30 inverter I was quoted for isn't available and they will be installing a Diehl 2100S inverter instead.

It is a 2.2Kwp system that I'm having installed.

Fronius is a brand I've sen recommended, on here and elsewhere, but I know nothing about Diehl.

Can anyone who knows about inverters advise me whether this an acceptable/comparable replacement please?
Thank you
Everything will be alright in the end so, if it’s not yet alright, it means it’s not yet the end

    Hi
    Thanks for your reply
    I've actually managed to get this sorted now, after alot of 'discussion' I'm getting a Fronius IG20 (which, according to Fronius, will actually be better for me than the IG30 would have been!)

  • IG30 bit big for 2.2kwp
    IG20 better 1.8 to 2.7kwp
    still quite poor effciency @ 94% max
    depends on modules used
    better and more effcient newer inverters to 96/97% these days
    higher effciency modules and inverters
    quicker payback and higher FITs

    but there are global shortages on pv inverters for last year
    fronius recalled 10,000 this year
    best ask for a warranty extension
