rigth config to Start/Stop a micro chp with Multigrid

Hi all,

my system consists of a multigrid 48/3000 with ccgx, smartmeter and a 12.8kWh battery storage from BYD, on the AC IN 1 a small PV is connected. It's all configured as ESS.

Further i have a on Grid micro chp on AC Out1 that should be switched off when the battery is full. So i config the K1 Relais to switch on 60% SOC and switch off 55,1V Batteryvoltage . The Problem is K1 do nothing ?!
Can it be the K1 only switches if no AC 1 is present in ? How can i solve the Problem ?
Or is the desired function only possible with the Relais of ccgx?


regards

ESS

try using the AUX1 or AUX 2 relay outputs as you can control when these close or open using the assistants.


If I am missing something here please attach a copy of you assistants setup

Hi Paul,

thanks for answering. I use the AUX1 ( K1 Relais ) with Assistant but the Switch do nothing, no Start if the Battery under 60% and no Stop if the Voltage is over 55V.

I suspect you are missing the General Flag to ignore AC or AC in 1

I have attached what I do. keep in mind my Multi is a different model to yours.
