QC your Updates
Your upgrades have clearly not be tested.
The inverter options are a random list of inverters in no particular order. This creates a HUGE WASTE OF MY TIME trying to find the right one. Can't you just alphabetize them (I can't believe I'm having to point this out to you).
Also, when I add a battery to option 2 it is actually adding it to option 1. WHY?
Your "fix" to the Utility input section has made inputting monthly kWh usage so much more laborious. It used to be simple to TAB through and add kWh, hit enter. Now TAB send you to a completely different field.
It's great that you want to keep making improvements, but PLEASE have an installer QC your improvements BEFORE you release them to everyone.
