Hi,
Is there a maximum write cycles on a GX device (RPI) for the DVCC current limit?
I think about the SD card write cycles in particular.
Or is it only stored in RAM and safe to modulate dynamicly?
Every flash device has its limits so it is wise to at least filter out writes with the same value. Or those within a certain threshold.
By the way. Why exactly do you want to change this setting so often? Note that I also use a flow to set the charge current.
Yes. I do know that you don’t need this example, but it is shared so that other people can see what I mean with ‘filter’.

I have a primary parallel ESS system with external energy meter. I use the surplus solar energy to charge a secondary system. I programmed an integrator to raise the charge current if the grid meter goes above a certain threshold injection power. If under that threshold I reduce the charge current. With a secundary hysteresis I also switch the state of the multiplus. The system works perfectly and follows the surplus solar enegy perfectly analog. So funtional it works perfectly but I am not sure every DVCC max current modulation is also sored on the raspberry pi’s SD card or not. If so I will run into write-cycles problems. If I change the sytem to MQTT write directly to the multiplus system (W/your_VRM_portal_ID/vebus/your_vebus_ID/Dc/0/MaxChargeCurrent) I move the same risk at the miltiplus memory system. I rather replace an SD card than a multiplus offcourse. I need an anwser from someone who really knows how the memory system works. This is my current controlling flow:
