Disconnect Combiners

Disconnect Combiners

SolarBOS disconnect combiners incorporate an integrated load-break switch into the combiner box. This allows system integrators to greatly simplify the installation of a PV system. SolarBOS offers disconnect combiners in 100, 200, 250, 320, and 400-amp sizes in NEMA-3R, 4 and 4X steel or fiberglass enclosures (stainless steel is available by request). All combiners are rated for continuous duty.
