question

What is your grid setpoint?

Hi,

I set in Cerbo Gx / Settings/ ESS / Grid setpoint (well Point de consigne du reseau, in french ... ;) ) at 50w.

Is this setup for max feed in Grid but also but power in from Grid? Could I change to 20/10 or even 0W?

Lowering the set point may improve your current small continuous grid use, however you will not be able to stop your system using an amount from the grid when a large load is turned on simply due to the speed at which the inverters ramp up their output to meet the large load, you will also see an amount of export when the large load is switched off - again due to the speed at which the inverter/s ramp up/down

DVCC should be on.

Parallel systems are less efficient, the setpoint is also affected by the accuracy and quality of the wiring.

Lower the setpoint as suggested. Check the inverters are well balanced, this will affect the experience.

A clamp meter is best for this, else there are node red flows that can help.

Alternatively, disconnect from grid unless absolutely necessary. There is an assistant for this, or script the system to switch to invert only.

Hi all,

Lot of nice feedbacks and guidances! Really appreciate! Thanks

About glitches, I was thinking about the inverter speed. Thanks for the confirmation.

I lower the setpoint, says 20 and see how it will work Then I fine tune in a way or the other. I feel setpoint reduction would increase current spike either in magnitude and/or duration. Working as a kind of reference for the internal inverter architecture. But I could be wrong.

I will check the wires, sure they are identical DC & AC, but not measured during on a large current for a heavy load. I hope for no surprise ;)

I need to read again DVCC chapter to clean up its setting. Its activation is on the todo list, only pending reception of a BMS - Cerbo adapter. I may enable it ealier ;)

I would keep the Grid connected. But keep the script idea somewhere in mind.
