Getting Bids for a 7kw system with Fronius Primo 7.6-1 inverter

I'm getting information from some installers. The7-KW size is based on a review of my year's utility billing.
This bidder says they will use a Fronius grid tie inverter. Is that a stable and acceptable brand?
If I wanted a battery backup to be added later, what Hybrid Inverter should I ask for?
Panels are guaranteed to be "Tier One", so no brand name, yet.
Thanks for the help,
Bill

If you historically have had reliable Grid Power, perhaps a backup generator and transfer switch is better than a battery bank wasting away for 5 years and then getting replaced.

No info on Delta. I can ask my grid installer buds?
For a Hybrid in NA I would use Schneider XW or Outback Radian.
Your panel above is barely Tier 1. To me, a Tier one panel has a product warranty of 25 years. Sunpower, Panasonic, and LG.
