Limit Grid max charge to certain value (ESS setpoint) when SoC < Desiree SoC

Q&A and troubleshooting

How can I limit the input power when:

  • ESS setpoint is set to certain value (let’s say 2000W)
  • Desired minimum SoC is raised big.

It’s starts charging automaticly at full power, and not at the desired ESS setpoint.

I don’t want to limit the current, because on a 3phase system the result is far from close to 2000W.
The point would really be to charg at the desired Wattage.

Thanks!

what set point did you set?

You can limit with your input current limit. (This has its drawbacks)
With DVCC - this limits all charging sources in the system.

If it is grid charging you want to avoid then program each inverter on the charger tab to low amps charging.

The other way is min SOC in case of grid faliure - but you say yours is big? - then it doesn’t charge from grid but waits for solar to do so.
