DC Coupled Residential Battery Systems + 2 MPPT inverters was created by yashagarwala
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,
Yash Agarwala.

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.
