Review for Fronius USA
I have two Fronius IG 4000 inverters. Both have failed over the past year one was replaced with a rebuilt inverter that shorted out when installed. Seems they don't test the rebuilt inverters before they are sent out.
They refuse to fix the second and have offered four separate excuses why it is out of warranty or not their fault. This product is not worth the money and the support is very poor. The service is so bad that independent solar service people seem not to want to deal with Fronus.
