This is a fully refurbished SMA SWR1800-U WITH POSITIVE GROUND configured for SUNPOWER POS GROUND PANELS. I would call this one ” near mint condition”. For many years these were the best workhorses in the solar industry. I refurbished it and reset the hours and KWH counters. If properly treated it should give many more years of reliable service.
