SAM Round Table

The SAM Round Table is a series of online meetings with the SAM development team. The meetings are every other Thursday at 2:30 p.m. U.S. Mountain. Each session lasts up to 30 minutes, and provides an opportunity for you to ask us questions, make suggestions, get help using SAM, and share information with other SAM users. To participate, please register for a session using the following link. Registration is free, and requires a computer with an internet connection (audio is available by phone or VOIP):

Are there any plans to add a hydropower model to SAM?

How do you use SAM with Microinverters (APSystems)

The SAM setup seems to only allow string inverters... As most installs are shifting to microinverters and APSystems is the manufacturer of choice for these products I'd like to know how to use them here.

Is there a pre-made datafile for the YC-500A and YC-500i at 240v, YC-1000 3 phase in 208v, 480v with the correct settings and inputs?

Any update on when multiple MPPT inverters will be supported?

Multi-MPPT inverters have been on the market for a long time now, other software supports them, when can we expect SAM to support them?

Thanks

Daylight savings support

Are there any future plans to include support for daylight savings? With TOU electric rates it would be helpful to have an option to include daylight savings.

Hourly sell rates window in Electricity Rates

I’m using the 2017.1.17 Mac version of SAM. In Electricity Rates when I open the hourly sell rates window to edit the time step data it would be great to have a way to enter one value and have it copied to all the time steps.

Thanks

Generic storage for Wind farm

Hi dear developers of SAM,

I'd like to simulate the impact of a storage technology on the output (financial & power) of a wind farm. However, I haven't found if it was possible to add storage to a wind project. I found this option in PV project but here, it was specifically for inverters.

Have I missed something, or do you think it's even possible ?

Regards,

Fabien Chaufournier

Battery Storage on AC vs. DC bus

Hi everyone,

This may be obvious to some, but why is the battery storage model on the AC bus only? In practice is this how systems are designed? It would seem to me that placing the battery on the DC bus would negate the additional DC-AC, AC-DC, and then back DC-AC efficiency losses created by placing the battery on the AC bus as opposed to the DC bus.

If in practice the battery is on the DC bus would that be a feature that could be added back to SAM? I read elsewhere that SAM used to have it.

SAM Interpolation Function

Does SAM come with any predefined interpolation function? I was just wondering if there is, because the simulations I'd like to do will warrant some interpolations. Thanks.

Bug in Mac version?

In working with some students using SAM (version 2016.3.14), we discovered that one student who used the Mac version received different results from the rest of us. In particular, it seemed as if the shading calculations resulted in significantly lower output for the student using the Mac version, with the same input values. Is this a known issue?

I can provide more information, including the SAM files we observed this with upon request.
