quatro 8kw

i have a system what contain one 8kw quatro, 150/100mppt , 21 solar panel 325w, 8 battery 220ah, and one color GX . Maxim value of production 5.5kw for more the 6 hours pe day.

I like to push in grid the exeses when i dont have consumption. The engineer(from the grid) from Romania is asking me and to proves/show to him how the quatro is reacting on variation of input voltage and variation of frequence and if is stopping on this problems(variation). He wonts in writing to see and physical.

thx for help.

@apophis

Do you have a GX device connected and is it transmitting to the vrm? You could use the csv data logging for that. Or just show him in the screen.

The .csv data shows grid voltage and frequency as well at the victron as well.

Victron also have certification for various grid codes. Not sure what Romania have as code

There should be some local regulations for grid feedback though so the Engineer should know these.

Antiislanding is an issue for safety reasons. There is a built in mechanism in the quattros. Some countries require an external device for this still though.

You will need a GX device to setup an ESS.
Maybe you will need an energy meter and depending on you local laws an anti-islanding relays.
