I turned off a device connected to my solar setup today and when it powered off I heard a beep. Upon further inspection I realized it was the high voltage alarm on my inverter turning on momentarily. I turned the device on and back off and realized from looking at my battery monitor that the voltage was jumping up to 15v or more for a split second (my lifepo4 battery is charged to 14.6). when I the load goes away. I also charge this battery from a sterling battery to battery charger, so I turned off the solar charge controller and started up the vehicle to start using that charger exclusively. When I turned off the device, this time the issue did not happen.
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.
