Setting max and minimum volts on the growatt spf5000es.

[Dtpmatt]

I have just installed my spf5000es with 3 pylontech us5000s.

When I try to set the maximum and minimum voltage for charging, it just shows % not volts.
And I doing something wrong here?

Thanks in advance.

If it's showing %.
I assume that you are using closed loop communications?

Im using the comms cable in the can outlet.

Im using the comms cable in the can outlet.

This is why it is showing % instead of voltage for some settings.

When I tried the other outlet I kept getting fault codes 4 and 20.

My dip switches are set to 1000 and I have no more faults so something is happy.

Ive set the growatt to 40% and 90% as seen on some YouTube vids. But I would be happier setting the voltage.

Ive seen somewhere a post to make your own comms cable, I should maybe try and find it and see what I can cobble together.

It's working correctly.
You can't set voltage on those settings, while using communications.

Exactly, the BMS (Battery management system) inside Pylontech us5000s is taking control over the charging parameters etc from the inverter if you use Lithium communication mode.
