Blue Oak PV Products
HomeRun Combiner Boxes
NEMA Rated, UL Listed

The Homerun™ Combiner Box family was developed by a team of experienced engineers and electricians to reduce the cost and simplify the installation of PV systems. Not your average combiner box, the Homerun line is designed to be tough, weatherproof and easy to use. The HOMERUN combiner box is the #1 choice for top-shelf solar array designers and installers.

This product line is UL Listed for safety as an inverter accessory to standard UL1741. An important aspect of the safety listing is the wide temperature testing range which ensures the product will safely deliver full power in the most extreme conditions.

The HCB 4 enclosure is powder coated aluminum. The weather-sealed, hinged design allows for vertical or sloped mounting.

The HCB8 and HCB12 are housed in a rugged fiberglass enclosure with a NEMA 4X rating, which delivers superior resistance to harsh weather and corrosion. The weather-sealed, hinged design allows for vertical or horizontal mounting. Inside the enclosure is a user-friendly layout with ample room to route and organize solar array conductors.

What do the NEMA ratings mean?

Type 3R     Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (rain, sleet, snow); and that will be undamaged by the external formation of ice on the enclosure.

Type 4X      Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (windblown dust); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (rain, sleet, snow, splashing water, and hose directed water); that provides an additional level of protection against corrosion; and that will be undamaged by the external formation of ice on the enclosure.
