I took 3 of these out of service 2 years ago. 1 is dead and the other 2 work. 2 have comm cards and 1 has a display card. Input is 250-600VDC PV output is 240VAC. 2500watts. They were part of my PV system for 18 years until 1 died and then all 3 replaced by 1 new SMA. Anyone have any interest? Located in NJ.
