[RE-wrenches] Has anyone had Magnum Energy PT-100 controller failures

[Starlight Solar Power Systems]

Hello Battery Wrenches,

I have installed about 35 of the Magnum PT-100 charge controllers since November 2015. I have had about 10 fail, another one just today. The problem we have is the same every time: network communications fail which causes other problems until you remove the network cable from the controller. The controller functions fine otherwise.

Some failed upon installation, some after a few weeks, others have lasted several months. Magnum has been making changes to the controller to try and fix it.  Has anyone else had a PT-100 failure? 

Thank you,

Larry
