Works wonderfully (autostart/shutdown w/Honda EU7k). I wish I had done this years ago. But there is probably a lot to be said for managing the system manually, first. Then automation is easy.

Yesterday was the first time the unit started, ran and shut down on its own. Today was the second. We've had several cloudy days with the first real rain since spring. The 2 min trigger executed and shut down flawlessly. I did have some weird startups and shut downs that didn't make sense along with the auto start just plain ignoring manual commands from the Mate3. Ultimately Kurt's recommendation to disable all the other rules solved the weirdness - I never did figure out which rule was causing the problem(s).

For the time being the 2 minute startup triggers at 48.8v and absorb is set for 1 hour. At shutdown this leaves me in the lower 90's for SOC. I am now tracking overall fuel consumption which looks to be up a bit. I'm not surprised. Since the EU7000is is more than twice the size of the Champion it replaced so it stands to reason. If its worth messing with, I could easily use the Champion for the extended absorb once a week or so since it has plenty of headroom during the absorb cycle and I wouldn't have to change any programming. It would just be a manual run. We'll see.
