It seems that my EVCS is not optimising its power required to keep the battery charging to a minimum.
My EVCS is now starting to charge the EV from 40% battery, then charges nearly fullpower and is using the battery with 1200W or so. This stops when the battery falls below 40%, the battery is then charged again to 40% and it starts over.
Possible solution...
I could limit the max power to kind if solve this issue.
Ideal solution
An optimal regulation that would start charging the EV from set % (40 in my case) and not use the ESS battery, then when the EV is full continue with the battery. This would keep the battery and inverter losses to a minimum.
Most likely solution
Me just having a setting wrong..
My system:
- 3 fase 48v5000 MPII With external AC sensors on Grid
- Cerbo-GX
- 2 AC PV inverters
- 8Kwh battery
- 2 EVCS
- ESS with grindsetpoint -3000 (poor grid connection)
