A case study
Over the past few years, numerous

solar energy monitoring solution
providers have migrated from close-
ended datalogger and RTU solutions
to an open, ARM-based computing

platform. It’s not tough to see why in
the following example.
In this situation, the solar energy
monitoring system builder used a ELIMINATE THE GROUNDWIRE FROM YOUR SOLARMOUNT ARRAY

he biggest problem that arose related
to the inlexibility of the protocols

It’s also worth noting that most
