MidNite Solar MNPV-12 Combiner Box

MidNite Solar offers a range of PV Combiners from our MNPV3 to the MNPV16. This range of combiners accommodates PV systems as small as a two string off grid cabin up to 16 strings for a 100KW 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 MNPV3 Combiner is for 150 VDC charge controllers and 600 VDC grid-tie inverters. Gray aluminum type 3R rainproof enclosure with insulating dead-front, will accept three 150VDC (MNEPV) breakers or two 600/1000 VDC fuse holders. With modifications to the dead-front 3 DIN rail fuse holders can be used. Includes a 60 amp plus bus bar, 6 position PV negative bus bar and a 6 position ground bus bar. Punch out tabs on the plastic dead-front make for a clean installation using circuit breakers. An included vsnap in adapter makes for a professional looking installation when installing fuse holders. A single 300VDC breaker from 7 to 50 amps may be installed as a disconnect (no combining busbar). The enclosure may be mounted to a pole or wall indoors or out. Breakers/fuse holders sold separately. 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 deg (vertical to 3/12 slope). Listed to UL 1741 for the U.S.A. and Canada. Breakers and fuse holders are not included. 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).
