EVCS don't start - waiting for sun

Do you have any feed-in ? If not, you must change register 5091 to -10000.
Maybe printscreen will help.

No feed in. How to change register ?

Please check my posts here, there must be a print screen from the SW.

it’s seems that now the value should be in register 5092 …

In this sw it’s possible (don’t know why it is)
Change to -10000 and you will see.

@Nicolas I think the problem is when the installation has set grid setpoint to -200 W (minus 200 Watts). In that case, the auto mode does not work at all.

Why do people set the grid sepoint to minus values? Because of slow Multiplus regulation, to prevent paying for expensive electricity from the grid.
Or for “energy sharing” purposes: in our coutry , you can “share” the produced electricity to family members etc.
When you are sending the electricity to 10 another households, you can do so nonstop, to cover their minimal household consumption .

Really grid setpoint to -200W ? I think better is set grid setpoint to 0 and set feed-in limit to -200W.

I think you didn’t get it.
