Rugged and attractive powder-coated aluminum rainproof array combiners accept DIN mount 150 V circuit breakers, MidNite 300 VDC breakers, or 600 VDC fuse holders for solar grid-tie arrays. Hard attractive plastic cover provides a dead front for safety and can be knocked out for either breakers or fuse holders for a great combiner box. Use for 150/300/600 VDC.
Combiner box offers both negative busbar and ground bar are included. The aluminum NEMA 3R enclosures are approved to be mounted at angles from 90 to 14 degrees (14 degrees = 3/12 slope).
UL 1741 for the U.S. and Canada. Breakers and fuse holders are not included.
Grid tie Solar PV panel MidNite Disco line of PV combiners with disconnects incorporates NEC 2011 requirements.
Attractive and functional disconnect handle is bright red for visibility and can be locked in the off position. Several models can be configured for bi-polar or ungrounded inverters where both the positive and negative legs of the array need circuit protection (maximum output current is split also). Models are available for 150 VDC, 300 VDC, 600 VDC, or 1000 VDC solar PV arrays in the field.
Combiner boxes are made from powder coated aluminum for corrosion and sunlight resistance for long life in harsh conditions. A clear see-through dead front is supplied with all disco combiners.
Combiner box models are available with either NEMA 3R or NEMA 4X ratings. Combiner grid tie boxes come with a shunt trip disconnect that enables the MNDiscoPSB to trip the disconnect remotely.
MNSPD-600 is included standard with many of these combiner boxes.
