AMtec Solar releases new contactor combiner box and remote disconnect control panel



October 12, 2011 – AMtec Solar released a new line of solar combiner boxes with disconnecting DC contactor and remote solar combiner disconnect control panel. This combination promises service and emergency personnel push-button control to open or close string level outputs at either the combiner box or up to 1500 feet away at the control panel. The ability to disconnect the solar combiner boxes from a distant location adds a previously unavailable level of safety for emergency responders, says AMtec. The solar combiner box with contactor disconnects is available in two configurations: 12 string and 3 x 12-string (36 string total). Each 12-string circuit is rated for 200A continuous duty. The 3 x 12-string configuration is built into a single enclosure. Each of the 12-string groupings has its own dedicated disconnect, making it possible for a service technician to safely disconnect each 12-string circuit at the combiner box when desired. Meantime, the solar disconnect contactor control panel is available with or without green and red LED status indicator lights; the lights help personnel see whether DC contactors are open or closed. A built-in battery provides indicator light backup power for up to 7 hours in the event of power loss to the facility.
