Dyness SOC with Voltage cap in dvcc

@lxonline

I will straight up say i think Dyness have some work to do.

Could you please elaborate a bit more ?

@lxonline

For feed into happen, the system raises the DC bus voltage 0.4 above (usually the programmed) battery voltage.

Yes, that has to happend so the current flow will take the intended path.

But, being BMS controlled, the Multiplus charger parameters should be ignored, right ?

@lxonline

Is there a reason why you want to feed in from dc coupled not ac couple pv?
It is more efficient to use ac coupling and use dc coupling for the battery specifically.

The AC coupled always power consumers and feed-in the excess but sometimes, with less irradiation, I thought to enable DC feed-in to reach the maximum allowed.

Is it a good practice to use the MPPT only for battery and, if required, for “helping” the Multiplus ?

@lxonline

Does the Dyness Powerbrick DL5C shift the CVL ever/at all?

CVL never shifted from 56.5v
