Should I go with the Mate3 or Mate3s?

Post by pioneerMan »

I was sent the following from tech support at Outback:

"The MATE3s has a set of advanced parameters known as “Grid Interface Protection” settings. These provide the inverter(s) in the system with the utility specified conditions for staying connected to the grid in different conditions. There is additional information If you scroll to the bottom of the page at the link here: https://outbackpower.com/resources/safe ... connection."

I read through the webpage they suggested, and most of it was over my head. Bottom line, why is California forcing these regulations on the whole nation? Should I even care since I'm completely off-grid and will never be using grid-tie hardware?

What has been your experience with using the Mate3s? If you had to do it over again, and you are completely off-grid, would you have just stuck with the Mate3?

Thank you.

Mate 3S unless your inverter does not support it.

The Mate3 is discontinued.

The Mate3s has lots of advanced features I don't use off-grid. It has more robust ethernet hardware that I do use off-grid. It will be the most supported of the two in the years to come.

I had a Mate3 for my grid-tied, garage roof system and it worked fine for me for a couple of years. When it failed under warranty OB sent me a Mate3s to replace it. Can't say I really noticed a dIfference, besides the fact that it worked.

Having said that, I'd go with the latest, greatest if I were you.
