MidNite Solar MNPV3 Combiner Combiner Box

Midnite Solar, Combiner box, 60A for 3 PV breakers or 2 fuseholders, MNPV3

From the MNPV3 to the MNPV16, MidNite Solar has a PV Combiner for you. PV systems as small as a two-string off-grid cabin up to 16 strings for a 100KW commercial grid-tie inverter can be accommodated by this set of combiners. The MNPV series of combiners is the culmination of 20 years of renewable energy design and manufacturing experience.

The MNPV3 Combiner is designed for charge controllers with 150 VDC and grid-tie inverters with 600 VDC. Three 150VDC (MNEPV) breakers or two 600/1000 VDC fuse holders would fit inside the gray aluminum style 3R rainproof enclosure with insulating dead-front. Three DIN rail fuse holders may be used with modifications to the dead-front. A 60 amp plus bus bar, a six-position PV negative bus bar, and a six-position land bus bar are included. Punch-out tabs on the plastic dead-front allow for a clean circuit breaker installation. When mounting fuse holders, a vsnap in the adapter is included for a professional appearance. As a disconnect, a single 300VDC breaker rated from 7 to 50 amps can be used (no combining busbar). Indoors or out, the enclosure may be attached to a pole or wall. Breakers and fuse holders are available separately.

These DIN-mount 150 V circuit breakers, MidNite 300 VDC breakers, Midnite 600 VDC breakers, or 600 VDC fuse holders for grid-tie arrays can fit in these powder-coated aluminum rainproof array combiners. A plastic cover, which can be knocked out for either breakers or fuse holders, offers a dead front for protection. A negative, as well as a ground busbar, is used. The aluminum NEMA 3R enclosures can be placed at angles ranging from 90 degrees to 14 degrees (vertical to 3/12 slope). For the United States of America and Canada, it is classified as UL 1741. Fuse holders and breakers are not included.

Three single-pole 150 VDC (MNEPV) breakers or two 600/1,000 VDC fuse holders can be used in the MNPV3. A 60 A positive busbar, a six-position PV-negative busbar, and a six-position ground busbar are included in this package. As a disconnect, a single 300 VDC breaker rated from 7 to 50 A can be used (no combining busbar).

Six single-pole 150 VDC breakers or four 600/1,000 VDC fuse holders can be used with the MNPV6. A 15-position PV-negative bus bar, a 14-position ground bus bar, a 120 A positive bus bar for breakers, and an 80 A bus bar for fuses are included. Two grid-tie inverters or two charge controllers can be assisted by splitting the positive busbar. A popular negative PV bus can be found in most charge controllers and grid-tie inverters (except Schneider XW and BlueSky).

For charge controllers that accept input voltages up to 300 VDC, the MNPV6-250 can hold up to three single-pole 300 VDC circuit breakers.

12 single-pole 150 VDC breakers or ten 600/1,000 positive VDC fuse holders can be used with the MNPV12. It has a PV-negative busbar with 15 positions, a land busbar with 15 positions, and two 200 A Plus busbars for breakers or fuses. To assist two grid-tie inverters or two charge controllers, positive busbars can be combined or split. A popular negative PV bus can be found in most charge controllers and grid-tie inverters (except Schneider XW and BlueSky).

For charge controllers that accept input voltages up to 300 VDC, the MNPV12-250 can hold up to six single-pole 300 VDC circuit breakers.

16 single-pole 600 VDC fuse holders will fit in the MNPV16. Includes a PV-negative busbar with 21 positions, a land busbar with 18 positions, and 240 A positive and negative busbars.

Up to 24 single-pole, 150 VDC breakers can be accommodated by the MNPV16-24 PV combiner. Two dozen 10 A breakers, sixteen 15 A breakers, twelve 20 A breakers,s or eight 30 A breakers can be accommodated by the 240 A busbar. Thanks to its ability for larger cables, this combiner is suitable for combining Aquion battery stacks.

12 single-pole 300 VDC breakers can be used with the MNPV16-250. Includes a PV-negative busbar with 21 positions, a land busbar with 18 positions, 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.

Features

• User Friendly - Plastic injection molded dead front covers on the inside. Depending on the model number, 150VDC and 300VDC breakers or 600VDC fuses are used. On some versions, two different inverters or charge controllers are adaptable.
• Efficient- Knock-outs that accept waterproof strain reliefs, conduit, or panel mount MC-type connectors. Knock-outs for lightning arrestors.
• Safety - Aluminum rainproof type 3R enclosure. ETL listed to UL1741 for use in the US and Canada.
