Best mode to use with export limit

[silencer2008]

Hi everyone,

I have a current export limit of 1.5kw from supplier, but with a 10kw solar system + 10kwh battery.
Does EVCC know there is excess solar available even with export limit enabled ?

Would solar or min+pv be better ? Any other configs need to be done for higher charging rate ?

Thank you all

evcc doesnt know about your export limit.. evcc only use the grid-meter output to calculate the max charge power.. I think your solar/battery-inverter should handle this.

ok, that was your question.. I think you should have to play with a negative threshold

ah yes that makes sense.
I have residual power set to 200
would i then set threhold to be -1300 so min charging would start then ? would i then add mincharging current etc?

We are export limited to 1.5kw, so still confused how evcc will increase charge power when it only sees 1.5kw grid export when minimum charge power is 4.1kw

I think this should work without an threshold. In one interval evcc sees 1,5kw power to increase the charge power. When in the next interval still 1,5kw power to the grid is, it will increase another 1,5kw at the charge power. So it may take some interval to get to full charge power, but I think this works.

But only with the restriction of 1 phase charging or the charger can switch automatically. If only a 3 phase charger is available it never will start.

I see
But we have 3 phase so minimum would be 4.1kw. Any suggestions ?
we also have a TCW3 so unable to change between 1p/3p
