I should also mention that when the load is turned off and the voltage spikes, the three lights on the front of the charge controller flash.
It seems to me that the solar charge controller is causing the problem? It only seems to be happening after the latest update? This is a brand new problem. We have been using this device for a couple of months without any issues till now. Very strange! Any advice would be appreciated. I have to disable it for now which stinks, but at least I have a backup charging method.
