It's a Solaredge system, producing about 11 MWh each year which is about half of our need. We didn't invest in battery packs because it was not worth the price. Looked at battery packs again just two weeks ago and is still too expensive. We sell back what we don't use. One of the best investments we ever made, especially since we use electricity to heat our home and also charging our cars. One EV and one PHEV, both will be upgraded later on this year with two new EVs, which we ordered last year.

Good luck. You won't regret it.
