Off Grid Starlink Power Usage

I have a rectangular dish I got early 2022. I have an off grid solar power system running it, so I like to keep track of how much power various components are using.

The Starlink system sits by itself on a smart Victron Energy inverter (a small computer and other things work on a separate DC-DC converter from the battery). The inverter posts status to a serial port about once a second. Across 883129 data points (about 10 days) I gathered data and did some analysis.

The mean AC current supplied was 0.32 Amps. The peak was 0.9 Amps. (The mean AC voltage output was 120.01.)

Here's a histogram of the number of samples at each output current:

0.2 A	88114
0.3 A	556319
0.4 A	215524
0.5 A	19858
0.6 A	2627
0.7 A	560
0.8 A	114
0.9 A	13

I've seen other reports that the Starlink terminal uses about 40 watts and we're in the neighborhood of that. Also the good news is I'm well within the specs of the 250 VA rated inverter I got for this.

I plotted the results but didn't see any pattern to the spikes. Nothing jumped out like "once an hour" or "every morning at 2am". Maybe it has to do with where the satellites are, the weather, or birds flying over head.

I'll keep collecting data but I'm not expecting any updates to this. But yay, now I know.
