Complete brand new old stock 10.0KW Fronius / Sunpower UNI  inverter consisting of 2 units with factory warranty.

We have a few more of these and will give you a deal if you buy a full pallet ( 4 units ) contact us for a quote !


Many people here on Ebay offer just the inverter, or just the disconnect/CPU, in both cases they are pretty useless without the other half, they are not interchangeable between types !!

This is a matched set of a  CPU/Disconnect , and the actual inverter unit that goes on top of the disconnect.

THIS IS A  UNI inverter that will work  ON YOUR 240V HOME CONNECTION !!!  ( and also on 208V or 277V )

More than 1 set available,  buy the best for less !

WE BUY, SELL AND PROFESSIONALLY REPAIR ALL SORTS OF SOLAR INVERTERS, FEEL FREE TO CONTACT ME IF YOU HAVE any quantity WORKING or DEFECTIVE INVERTERS or PARTS FOR SALE. As always, email me at gmail with questions!!     Hanssmitd at Gmail
