PV Master app keeps crashing when updating settings on Goodwe ES4.6kW

Question

PV Master version: 4.2.3

I can't update advanced settings on my Goodwe ES4.6kW inverter. If I make changes and hit "Set" the app crashes with a Java error complaining about java.lang.NumberFormatException: For input string: "". Looks like it's expecting a number but getting an empty string, but there are no empty fields that need a value. This happens even if hitting "Set" without making any changes.

Does anyone know if there's another way to make updates, e.g. via a PC or web browser and not a flaky Android app? The app used to work, but I expect it probably updated itself at some point. Build date of the app claims 30 Nov 1979 so no idea when it was last updated.

Hi DaleW,

The PV Master application will try and auto-update itself every time you start it and I see my version is currently on V4.2.3.

Have you tried installing the application on a different phone/tablet, to see if it is a device error perhaps?

Also, are you connecting directly to the Goodwe inverter Wi-Fi, or trying to connect through your home Wi-Fi?
