Frequently asked questions
solar generator for van life?
For a typical setup (starlink mini, portable 12v fridge/freezer (dometic cfx3 45 class), laptop computer, led bulb (60w equivalent) and phone / smartphone charger), you need at least 226W of continuous power. The single biggest moment is startup: when 1× portable 12v fridge/freezer (dometic cfx3 45 class) kicks on, the momentary draw peaks at 426W. For overnight runtime we recommend at least 2,340Wh of battery capacity (your devices use about 1,870Wh per day, plus a 25% margin).
Which power stations can handle this?
Based on published specs, Goal Zero Yeti 3000X, Anker SOLIX F3800, EcoFlow DELTA Pro 3 all cover the 426W startup peak and give you 1.6 days / 2.1 days / 2.2 days of typical daily use. Check the comparison cards above for the full numbers.
Why is the startup surge higher than the running watts?
Motor-driven devices (fridge compressors, well pumps, air conditioners) draw 2-5× their running power for a split second at startup — measured as locked-rotor amps (LRA). A generator that only meets the running load will trip or stall when the biggest motor starts.
