DC Coupled Residential Battery Systems + 2 MPPT inverters

Hi,

I'm trying to simulate a 17 panel 320Wp system on a 5 kVA inverter with 2 MPPTS coupled with a DC coupled LFP battery.

But, everytime I simulate it throws up an error saying that this cannot be done because the inverter has 2 MPPTs.

This seems weird to me because now I am unable to simulate any system above 10-12 panels.

Can you please help?

Kind Regards,
Yash Agarwala.

Hi Yash,

For now SAM cannot model a PV-battery system with DC-connected batteries with the multiple MPPT inverter option.

I have made a feature request here: github.com/NREL/SAM/issues/215

Best regards,
Paul.

Hi Paul,

Thank you for requesting for the feature. I am new to this so I am just wondering how long such requests take to be completed?

Kind Regards,

Hi Yash,

This particular request is not part of our current work plan. We plan to release a new version later this fall. I would expect this feature to be in a subsequent version, assuming we are able to get support from our funding partners to implement it.

Best regards,
Paul.
