Depends what sort of battery you're on. The cheapest car Tesla sells (or at least that is displayed to me when I visit their site), for example, has a 54 kwh battery. It could run a 100 watt load for ~22 days between charges (not counting driving). Or to put it another way, if you charge every day, and you never turn the dish off, this would only drain 1/22nd of your range.
- state_less 6y agoTesla batteries are sweet, but ~22 days isn’t long enough if you’re off grid full time. I am trying to keep power generation 100% solar rather than burn diesel/gas to charge batteries when I can. So 2.4kwh per day might require roughly 500 watts of additional solar panels in a sunny locale. More solar could be added, but there are some space and weight limitations on a vehicle. I’m at 1400 watts of solar now. Anyhow, just hoping they can figure out how to get the average power draw down over time.

If you start running low you can stop letting it idle. > More solar could be added, but there are some space and weight limitations on a vehicle. It can be a problem if you're off-grid and moving around, yeah. For general off-grid use it's annoying but not a big deal to set up an extra panel or two.
