I'll try the battery upload data again below.

I'm presuming you received the sam file?

Hi Bill,

Thank you for attaching those images. Pasting images into the editor does not work reliably.

The manual dispatch options that you defined on the Battery Dispatch page are as follows:

1 am - 4 am (Period 1): Battery can discharge at up to 2% of its available capacity.

5 am - 10 am (Period 2): Battery can discharge at up to 1.3%.

11 am - 5 pm (Periods 3 and 4): Battery cannot discharge.

6 pm - 8 pm (Period 5): Battery can discharge up to 10%.

9 pm - 12 am (Period 6: Battery can discharge up to 5%.

Here's a plot for October 8 showing the effect of these discharge rates: The slope of the battery state of charge (SOC) plot is steeper for periods with higher discharge rates. The battery supplements grid power between 9 pm and until the PV array starts generating power.

 

You can adjust the discharge rates in the manual dispatch inputs to increase or decrease the amount of power discharged from the battery.

You can plot additional variables to see how the system is operating: 



Note that the area under these plots represents energy in kWh.

Best regards,
Paul.

Many thanks!
I've misinterpreted the statement in the Help section for "Discharge to Load" settings:

Clarification Re: misinterpretation of Help topic- - When I entered "2%" for the period between 1am and 4am, I was thinking that I was calling for a discharge rate of 8% during that time period...not 2%.

Surely appreciate your guidance, Paul!
