Tips
- →Starlink Standard draws 40-75W (avg ~50W) = 1,200 Wh/day
- →Starlink Mini draws 20-30W (avg ~25W) = 600 Wh/day — half the power
- →For 24/7 operation, you need daily solar recharge to match consumption
- →At 1,200 Wh/day with 5h sun: need at least 320W of solar panels
- →Starlink has sleep mode scheduling — enable it overnight if you don't need 24/7
- →Use ethernet adapter to disable Starlink's Wi-Fi radio (saves ~5W)
- →Power stations with UPS function prevent Starlink from rebooting during switchover
