About the Solar Contactor Control Panel

At last, in an emergency, there is no longer a need to climb to the roof and go from combiner box to combiner box shutting them down. Now you can, with a single move, shut down as many as 45 contactors by pressing a centrally located EMO (Emergency Monitor Off) pushbutton. Your local safety inspectors and fire departments are going to appreciate this innovation.

Systems are available with and without contactor status indicators (open =red led and closed= green led).

An EMO pushbutton operator is a key-release device which when pushed inhibits further operations until key is inserted releasing the button and enabling the circuit. Once the EMO pushbutton is returned to its normal position, contactors close with a delay of 2 seconds between closures continuing until all are closed.

There is a battery backup system in the circuit monitoring box that maintains contactor status indicators when facility power is lost. The backup system supplies power to the indicators only, not the coil circuit. Battery reserve time is about 7 hours.

The units contain a charge controller with local status indicators to keep the backup battery charged. We integrated a battery low voltage disconnect circuit (LVD). The LVD circuit disconnects the load (led circuit) when battery voltage gets too low protecting the battery and remains disconnected until facility power returns and charges the battery.

Unit is powered by a Class II 90-95 Watt AC-DC power supply keeping the system power requirements low.

#16awg wire is recommended on the coil circuits of the contactors with runs of up to 1500 feet from the control panel. Greater distances can be achieved by using #14awg wire. If the control panel has the optional LED indicators, #18awg wire should be used for the indicator circuits.

The Remote Disconnect Control Panel is housed in a Nema 4/12 enclosure and is UL508a listed!
