Query about the accuracy of suggested charge and discharge rate from the 'auto generate charge curve' routines

[PianSom]

I have an AIO, and GivTCP returns number.givtcp_SERIALNO_battery_charge_rate and ...discharge_rate as both being 6kW. Looking at actual experience reported by GivTCP my battery is actually discharging at around 6.27kW and is charging at around 5.8kW

However the input_number.predbat_battery_rate_max_scaling_discharge and charge settings suggested by Predbat seem to bear little resemblance to these values. I am using the Predbat suggested values, but Geoffrey thought it may be worth checking that the Predbat suggestions are correct?

The curves seem about right to me, remember they are normalised to 1.0 so the global scaling factor is on top of these numbers. Of course they won't be 100% accurate so you might want to manually change them.

It is of course curious that discharge max seems to only be 90% of rated value so I don't know if this is as expected or not.

[PianSom]

Not least because the actual discharge rate reported is 5% MORE than the rated value! Hence the question.

(Wasn't really querying the curves.)

Probably down to losses, maybe you set them too high?
