Contactor Combiners

Contactor Combiners

SolarBOS contactor combiners integrate 600 or 1000 VDC load-break rated contactors into the combiner box, allowing system operators to remotely disconnect the combiner under load. They can also be configured to automatically disconnect whenever the building loses power or the master system disconnect is thrown (in the event of a fire or other emergency), thereby de-energizing the conductors between the combiners and inverter. Contactor combiners come in 175, 250, or 350-amp versions.
