SolarBOS, a provider of balance-of-system solutions for solar system integrators, has released the Contactor Combiner for commercial PV systems. This new product incorporates a 600 VDC load-break contactor in the combiner box, allowing system operators to remotely disconnect combiners under load and de-energize the conductors from the combiners to the inverter, the company says.
The products also can be set to automatically disconnect whenever the building loses power or the master system disconnect is thrown (in the event of a fire or other emergency). The Contactor Combiners are ETL listed to UL-1741 for up to 200 amps and include a through-the-door-style manual override switch that allows for local operation of the contactor.Â
