This is somewhat closing out a thread from the old forum, but for an off-grid system with LFP batteries, when the battery is in idle state and the car is plugged in, the EVCS remains in “waiting for sun” mode. I was requested to check whether hitting Stop & Start would re-initiate charging. Unfortunately, it does not. It appears that only when the house battery is discharged greater than the input potential from the array does Auto mode work as intended.
Here’s a video, sped up to help compress size, which shows the operation.
Why at 86% the pv power is limited? Try solving that issue and then the EVCS will start.
