Min/Max measurement
Minimum/Maximum registers values
•
The Min/Max registers hold the minimum and maximum values of Current from the time the
registers were last reset.
•
The Min/Max registers can be helpful in identifying bad electrical connections.
This can be achieved by calculating difference between Min values among nearby Strings.
Where one string is shown to have greater difference, it may indicate a possible problem with
the terminal connections.
7.5
Surge counter
The ProSMS has a built in surge counter which is capable of detecting and counting direct and
indirect surges to the panels, string cables or cabling to the central inverter.
The Surge counter has been optimized to work best with the Raycap PV ProTEC
surge protection series of SPDs.
