Paul,
With your guidance, I'm now producing the graphs from the time series, and feel like I'm getting closer to solving this.
The key issue is that I am not, at this point, able to show production of any electricity to the loads from the battery. SOC is fine, and the projected figures for kWh loads seems about right, but I'm only able to show power to the loads from the grid or solar. None from battery
Sure seems like there's probably a simple variable setting that I'm missing.
Thanks again for taking a look...I'll keep at it this weekend.
Regards,
Bill

Paul,
Another clue...Here's the data which shows about what I'd expect. The difference is that this is from running a quick model using PVWatts-Battery, Residential versus PV-Battery, Residential. Hmmm....
I've been using, and would like to continue using, PV-Battery, Residential, as it uses quite a bit more "actual" data than the PVWatts model.
I haven't been able to figure out why the difference between models with respect to the "Energy to Load to Battery" parameter. Obviously, there's something I'm missing.
Thanks again,
Bill

Paul,
Quick update...Looks like I've found the simple thing I was looking for. The battery capacity and battery bank sizing input format for values appear to be different in PVWatts - Battery, Residential versus PV-Battery, Residential Performance modules.
Please don't spend any more of your time on this at present...looks like I'm getting where I need to be with the models. The Time Series graphs you presented were very helpful in figuring out the problem I was having.
Thanks for the guidance! Bill
