Solar PV String Monitor A90DC-12
Obvius’ A90DC series is a twelve string DC current monitor used in smart combiner boxes that detects when panels in a Solar PV system are underperforming. The A90DC series can monitor configurations of 12, 10, 8, 6 or 4 strings using non-contact Hall Effect sensors. The A90DC series also includes a 4-20 mA input for monitoring voltage, ambient temperature or irradiance. The A90DC series provides open communications via Modbus RS-485 and can be easily retrofitted into existing combiner boxes.
The A90DC Series string monitor is compatible with virtually any Modbus Master. Use with the Obvius AcquiSuite to take advantage of plug-and-play communication or use with the Obvius ModHopper for wireless communication. Ask about the Obvius Configuration Console, a free commissioning software.
