Thanks all - really helpful and interesting information.

Also... could you please comment on:

  • How far your observations were from the closest gateway(s)
  • Whether you consider your cell Starlink virgin territory or close to subscriber saturation (https://www.starlink.com/map might help determine that - if it's light blue, it's likely= the former, if it's "waitlist" blue but surrounded by lig= ht blue areas, or rural and close to a "waitlist blue" area, it&#= 39;s likely to be the latter.

When a larger inverter failed upon installation, I ran Starlink with the router and rectangular dish for about 2 months, unattended, on a Harbor Freight 250W inverter and 8 GC2 batteries.

Unfortunately this sort of crashed and burned after the first snow. The battery bank was 8 GC2 in series, and there was a 48V-12V converter before the Harbor Freight inverter. I had 4 solar panels flat on top of a freight container, simply so that they would not be visiblle and the site would be low profile. These got covered by snow, and I will tilt them up before the next snow season. The batteries then got to a low voltage, and the lovely Victron battery protector failed because I wired it backwards. Then I had a heart attack and could not visit the site for 3 months. The=C2=A0battery bank discharged entirely. I finally arrived to find ice at the top of 4 cells in the battery bank. Fortunately it was only at the top, and I was able to recover all of the batteries, rewire the protector, and put the site back on the air.

At that point, I switched to DishyPowa, connected via a hacked Starlink Ethernet Adapter. This allows you to delete the inverter and the Starlink router, and run the dish directly off of 48-52V DC. You still need a router, because Starliink only provides one IPV4 DHCP address to the Dishy, and you need to do the usual NAT thing on your local net. But routers that run on 12V directly are easy to find.
