Hello,
I have been reading a lot on this forum and i am looking for a battery inverter with the possability to control the output power.
Because i already have a solar grid tie inverter (growatt, 3 phase 6kwp) i just need a battery inverter.
The goal is controle the outpus power of the inverter to load match so i have 0 usage from the grid.
i have a plc and communicate with my existing growatt inverter.
I also know the load at all times (in the house, used from grid or sent back to grid) so that way i can calculate how much the battery inverter needs to generate.
I can communicate through RS485, Can, or give a 0-10V signal, PWM, 4-20mA,...
The only big problem is that finding the battery inverter capable of doing this is not easy..
This one looks like a possability https://www.aliexpress.com/item/400...7#7559#56_668#3164#9976#773_668#3468#15607#32
But apparently no one figuted out how to communcate in a decent way. Also it looks like it is forbidden in belgium
I also saw this one: https://www.aliexpress.com/item/327...#7559#56_668#3164#9976#773_668#3468#15612#355
But not clear how it is possible to tell the inverter how much to output without the CT. (I want to control it myself, not via the CT)
Can anyone point me in the right direction, or even better, knows the solution for my problem?
Thanks!
