My 24v inverter turned into a 48v overnight!

[SeriousTree]

Growatt 24v inverter charged fine, then the next day it's beeping and throwing a code 19 and everything was reset as if it was , well....reset. but it was no longer functioning as a 24v inverter, all settings pointed to it being a 48v now. Has anyone ever seen/experienced this? I have a 24v Bigbattery Mule (3kw) and 1 Trina solarpanel 390w, which barely pushes 35v on a good day(200 watts approx.)

Also, now the solar panel won't charge or connect (via the inverter) to charge the battery. It just keeps restarting.

Firmware update gone awry?

I have heard on here that some things can be cleared up by
First disconnect solar input
Second turn off inverter
Third disconnect AC input
Fourth disconnect batteries
Let it sit
Reconnect battery
Reconnect AC
Reconnect solar
Turn inverter on
Cross fingers at what ever point you like ?

my bet is someone grabbed the wrong Firmware.

It's been updated with whatever was the latest firmware, but I'll check again. It just started suddenly, not sure why....I'm putting on my tinfoil hat though, ya never know....................................
