It is possible to remotely configure the SPF5000ES
(I assume you have the data logger shinewifi-F and the plant registered to growatt cloud server)
Solar assistant is quite poor when it comes to parameter set on the inverter.
But I use it frequently to switch mode SUB-SBU-UTI
1.
https://server.growatt.com/
2. Login
3. In the dashboard scroll down to "my photovoltaic devices"
4. On the right side press the button "settings" on the device you wish (if you have more than one)
5. Agree with the disclaimer in order to proceed further.
6. Press "advance set" to be able to see all settings/parameters
Almost at the bottom you have a drop down field (choose parameter) and a button "read" to get the current parameter value.
In the empty field on the bottom of the window "please enter key to save", you have to type the password. It remains in the box as long as you keep the settings box opened.
This is being sent when you press "yes".
The password includes the current date (no brackets ?):
growatt[yyyy][mm][dd]
So... choose the parameter you wish (upper list, radio button, only one can be selected), type in the value or choose from the drop down list, press yes.
After that you can read the parameter to check if it is the value you have written previously.
