This is the complete cabinet off of a DC solar trailer. It’s got 2 6000 watt sunny island SMA inverters. A classic 250 midnite charge controller and combiner box. It’s wired to receive your battery bank and panel array. This box cost around $15,000 to build. It’s got a locking cabinet with built in fans. Inverters have a 10 year warranty on them until 8/2027. Very nice and solid unit. Used very little 60.3 kWh total in its life. It came off of one of the last units made. $3000 OBO.
