I Have 200 Wats on the shed roof.

[sternwake]

I got all confused when the word inverter came into this discussion.
I was not sure what was the intention or goal after that.

Seemed like a simple mobile system installed into/onto a non mobile application, and how to keep batteries happy with 200 watts of solar on a barn roof when not cycling them.

Non cycling batteries need not see hours of absorption voltage each day, while cycled batteries do.
