Edison Solar offers a wide array of solar combiner boxes from the top names in the solar industry. Our combiner boxes range from 4 to 54 fuses, 75-480A, and will accept a DC Voltage of 300-1000V. Many models are housed in the famous NEMA 4 and NEMA 4X steel and fiberglass enclosures to ensure rugged durability in their applications.

Although designed primarily for combing PV strings up to 150VDC, the MNPV may be used for combining high voltage strings using fuses. The use of touch safe din rail mount fuse holders and fuses allow operation up to 600 Volts. This high voltage configuration requires a high voltage kit that consists of a bus bar and insulator to prevent arcing. Although the fuseholders are already UL listed to 600 volts, Underwriters Laboratories requires additional insulation when using these fuseholders with PV modules.

Square D

Square D is the premier name across industries for circuit breakers and disconnects. The solar industry relies on them for AC disconnects to shut off a system's power after the inverter. All of these Square D disconnects can handle up to 240V of AC current and have a NEMA 3R enclosure.
