MidNite Solar MNPV10-1000 Combiner Box

Midnite Solar, Combiner Box Enclosure, for transformer-less 1000VDC grid tie inverters, accepts 10 1000VDC fuse holders & fuses- sold separately, NEMA 3R, Gray, MNPV10-1000

Midnite Solar offers a range of PV transition boxes and combiners from its MNPV3 to the MNPV0 1000 volt to the MNPV8-MC4 pre-wired combiner.

The range of combiners accommodates PV systems as small as a two string off grid cabin up to 12 strings for a 50kW commercial grid tie inverter. The MNPV series of combiners are the result of 20 years of design and manufacturing experience in the renewable energy industry.

The MNPV10-1000 uses 1000 volt fuse holders (MNTS) and fuses (MN1000FUSE). Includes two 15 position PV negative busbars, 14 position ground busbar and two 220A Positive busbars. Fuse holders (MNTS) and fuses (MN1000FUSE) sold separately.

This combiner is intended for transformer-less 1000V grid tie inverters that need up to 5 strings.

These powder-coated aluminum rainproof array combiners will accept DIN-mount 150 V circuit breakers, MidNite 300 VDC breakers, Midnite 600 VDC breakers, or 600 VDC fuse holders for grid-tie arrays. A plastic cover provides a dead front for safety and can be knocked out for either breakers or fuse holders. Both a negative and ground busbar are included. The aluminum NEMA 3R enclosures are approved to be mounted at angles from 90° to 14° (vertical to 3/12 slope). Listed to UL 1741 for the U.S.A. and Canada. Breakers and fuse holders are not included.

The MNPV3 will accept three single-pole 150 VDC (MNEPV) breakers or two 600/1,000 VDC fuse holders. Includes a 60 A positive busbar, six-position PV-negative busbar and a six-position ground busbar. A single 300 VDC breaker from 7 to 50 A may be installed as a disconnect (no combining busbar).

The MNPV6 will accept six single-pole 150 VDC breakers or four 600/1,000 VDC fuse holders. Includes 15-position PV-negative bus bar, 14-position ground busbar, 120 A positive bus bar for breakers and 80 A busbar for fuses. The positive busbar may be split to support two grid-tie inverters or two charge controllers. Most charge controllers and grid-tie inverters can have a common negative PV bus (except Schneider XW and BlueSky).

The MNPV6-250 will hold up to three single-pole 300 VDC circuit breakers for charge controllers accepting input voltages up to 300 VDC.

The MNPV12 will accept 12 single-pole 150 VDC breakers or ten 600/1,000 positive VDC fuse holders. It includes a 15-position PV-negative busbar, 15-position ground bus bar, and two 200 A Plus busbars for breakers or fuses. Positive busbars can be combined or separated to support two grid-tie inverters or two charge controllers. Most charge controllers and grid-tie inverters can have a common negative PV bus (except Schneider XW and BlueSky).

The MNPV12-250 will hold up to six single-pole 300 VDC circuit breakers for charge controllers accepting input voltages up to 300 VDC.

The MNPV16 will accept 16 single-pole 600 VDC fuse holders. Includes 21-position PV-negative busbar, 18-position ground busbar, and 240 A positive and negative busbars.

The MNPV16-24 PV combiner can hold up to 24 single-pole 150 VDC breakers. The 240 A busbar can take two dozen 10 A breakers or sixteen 15 A breakers or twelve 20 A breakerbreakers or eight 30 A breakers. This combiner is useful for combining Aquion battery stacks due to its capacity for larger cables.

The MNPV16-250 will accept 12 single-pole 300 VDC breakers. Includes 21-position PV-negative busbar, 18-position ground busbar, and 240 A positive and negative busbars.

The MNPVxx-1000 combiners use 1,000 VDC fuse holders and fuses, which are not included and must be added. The MNPV10-1000 only can be split into two output circuits.
