Battery state of charge

[Kristian]

Is there any way to start the PV stand alone calculation with fully charged batteries?

Hi Kristian,

I am afraid that this is not possible at the moment. Right now the starting SOC of the batteries in stand alone (offgrid) systems is determined by the average SOC that is roughly to be expected during operation. For that we take the SOC control parameters of the diesel generator:

Considering the time and the SOC thresholds we determine an "average" SOC that is used as a starting point.

This behaviour was desired by the SMA engineers to avoid untypical system behaviour in the beginning of the simulation (the offgrid simulation part of PV*SOL was design for SMA in the first place, some years ago).

But we will put this feature request on our list, thank you.

Kind regards,

Martin

Ok, thanks anyway!
