I’m able to reproduce the issue by disabling the SOC feed too. The issue seems to be due to
if (config.app.battery_soc.value)
evaluating to true when battery_soc has been disabled in the settings page. For me this then disabled access to the settings view when subsequently trying to access the app.

I managed to get access back to the settings view by modifying line 381 in mysolarpvbattery.php to set the optional property to false instead of true.
“battery_soc”:{“optional”:false, “type”:“feed”, “autoname”:“battery_soc”, “engine”:“5”, “description”:“Battery state of charge %”},

When one of the feed is disabled, then the graph is broken...
Tried with "Wind"...
