GlobalLink 520 Temperature Limits

Does anyone know the minimum temperature of the GlobalLink 520?

I recently changed out my CerboGX (temperature limit -20 C) with the GlobalLink 520. Using device with SmartSolar 100/30 MPPT (temperature limit -30 C) and SmartShunt (temperature limit -40 C). I will find out this winter whether or not this unit will work all winter in my unheated Alaska location.

The extremely low power consumption (measured at 10 mA) of this setup should survive the winter with flooded lead-acid batteries. With the CerboGX, I had to shut down the loads including CerboGX during -30 C temperature conditions.

Global warming has helped since it has been over 10 years since I have seen -40 C at my location.

Old setup for previous years used industrial rated (-40 C) components for all parts of the system; however, power consumption required me to limit operation to sunny days only.

The updated datasheet has a lot of good information that was not in old version. Thank you.


I have found that most of my devices will continue to work at slightly lower than rated temperatures. My industrial certified devices are all rated for -40 C. Internal chip temperature is usually 10 degrees warmer than coldest outside temperature.


This winter will be first full season with GlobalLink 520.

Currently my GlobalLink 520 is operating fine at -30 C. Internal temperature is -7 C. Is there any other real world cold temperature experience? I am in a warmer part of Alaska and would be interested to see if unit will operate in colder regions. Spec sheet shows -20 C minimum.
