Hey all,
Currently im working on a project with SMA inverters (uses Sunspec registers), where im building a node-red enviornment to read and control.
Below is my SMA inverter configuration along with what the dashboard looks like.
- i have set queue delay to 350ms (not seen on screenshot)
Everything regarding the reading part of the project works but control has some issues.
Regarding control, im curtailing with active power limitation and also as a project requirement i have to control reactive power.
For reactive power control, there are two registers that i work with.
1 - Reactive Power Mode ( 1 = on, 0 = off)
2 - Reactive Power %
Now the problem i have is with the Dashboard,
When i inject something manually, for instance, injecting 1 into the reactive power mode switch, the result is almost instant. I see amendments happening in the SMA web interface.
But when i use the form / button / switches for control on the Dashboard2.0, it works very unreliable.
- Sometimes it works in an instant, sometimes it takes a minute or two for it to get to the SMA inverter and changes to happen.
- an example of this behavior is, when i switch on the button for ON/OFF, on the debug node after the function, i see the change, 0 or 1. However, it just doesn't reach the modbus write node? or it does but it doesnt make any changes per say?
I have the same problem with the reactive power limit as well.
For some reason, for Active Power control/limit, it works smooth from both the dashboard and manual inject.
