Sorry for writing mistakes but english is not my own language.
I have an multiplus ll 5kva system with a cerbo, mppt's and 60kwh battery running a 230volt system.
My grid connection is 1 phase 16 amp
To peak shaving above the 16 amp is working perfect or the ess function is also working perfect.
My idea is use both of the functions together! Now i am doing that in a way when my battery is on 30% i set my maximum grid use on 2kw so the inverter is always able to give feed al the extra power that is needed. When the battery is full agean i set my maximum grit use back on 50 watt. In summer time i have enough power from the pv charge my battery every day full (or about full) but in the winter it is not enough.
Is it possible so to link the grid setpoint to the soc of the battery, for example
- soc 40 / 100% grid setpoint 50 watt
- soc 20 / 40% grid setpoint 1500 watt
- soc 5 / 20% grid setpoint 3000 watt
Or even more steps.
Is this possible or is there a way to make this work?
