The MNPV6-DISCO is a 6-string PV combiner box, usually for use with 150 Volt rated charge controllers. The combiner has room for six 150 Volt DC rated breakers. The combiner has a front lockable handle that mechanically connects/disconnects all six breakers at the same time. It has a gray aluminum NEMA type 3R rainproof enclosure with insulating dead front.

The MNPV6-DISCO is very flexible. It is ETL listed for AC and DC. This allows you to configure it for several different uses. It will work with 1-6 of MidNite’s MNEDC15 150 volt DC breakers. The combiner also works with 1 of MidNite’s 600 volt DC breakers for a grid tie disconnect. You can also install a 240 volt AC breaker with the 600 volt DC breaker to make a complete disconnect for a grid tie inverter. Load Break rated. This configuration makes a compact Grid Tie disconnect for those applications where the built in switch won’t do the trick.

Depending upon the model number, you can use:

  • Type 3R environmental rating
  • DC 600V (1 circuit Pos or Pos and Neg switched) OR DC 150v (6 Circuits) OR AC 120v (6 circuits)
  • DC 300V (3 circuits) Part #MNPV6-250-DISCO combiner
  • AC 240v 40 amps (3 circuits) Part #MNPV6-AC Micro-Disco combiner
  • AC and DC can be installed in the same box! Example: 600Vdc 20 amp PV in and 40 amp 240Vac Inverter output

The combiner comes without breakers. The 15 Amp MNEPV15 breakers are typically used with this combiner.
