The inverter should come with a manual that should make it clear what to do.
If you have the make/model of the inverter, any of us could find and
download the manual to help you.
What is normal is:
1) You download an app for your phone, and the app automatically
connects to the inverter over wifi. The app then also tells you all
the stats about your inverter, power used etc.
2) The manual tells you what IP address the inverter is, and you plug
a laptop into the ethernet port with a normal ethernet cable and type
"
http://192.168.0.1" or whatever the manual says the IP address is.
That should bring up the web page you are looking for.

You could maybe use a USB wifi adapter on the Pi zero and link to it
with wifi from your phone. Problem being, it will eat battery power.
There are lower power RF methods such as Lora or the many other onces,
but then your phone won't talk lora so you would need a dongle for the
phone. So I guess it's not ideal.
It depends on what you need to control on the battery box. Another
option is simply using infra red and use a TV remote with it to
control it. That is low power but Receiver only on the pi zero side.
