EV Charging Station - automatic mode for Inverter AC input connection

Hello,

I am using EVCS for a week. Firstly connected as "Inverter AC output" - everything works smoothly, manual and automatic mode as well. No complaints.

But then I changed electrical connection and setting to "Inverter AC input". Manual mode work fine. But Automatic mode sucks. If I use automatic mode, charging start at 6A and increase amps step by step. But it dont stop on PV excese power point, it continue increasing till max charging current setup is reached. Lets say, PV excese is 5kW, charger charge my EV at 11kW.

Is it EVCS bug or feature? Or could I change any other parameter in my ESS?

my system: 3x Multiplus 5000, Cerbo GX, 2x MPPT 250/100, 14kWh Pylontech, EVCS.

Cerbo, MPPTs and EVCS with last FW update.

Thank in advance for any help.

Pavel

Can you share a 10 sec video of the main page when this is happening?

Thank you for your reaction. I will do soon. Now I have to wait for better weather, it is cloudy here from yesterday :( No excesses now.

Here is a video of auto mode from charging start to reach of maximum charging current which not respect of PV excesses. Looking forward to any advice how to solve this issue.

Ok, but while the EVCS is sending more power to the vehicle, the measured grid power remains the same. So something is wrong with the installation. Where is the EVCS connected? Is before the meter?

EVCS is connected on Inverter AC input according picture...

there is no external energy meter. Energy is measured by 3x Multiplus I. inverters (3 phase).

That's why! You need to add a meter or connect the EVCS on the output of the Multi.
