Recharging with solar

The Goal Zero Yeti 500X accepts up to 120W of solar input. In real conditions that harvests about 450Wh on a sunny day (5 peak-sun hours).

Solar can’t fully keep up. A Wi-Fi router and modem uses about 480Wh a day at 24 hours of use, more than the Goal Zero Yeti 500X’s best-case solar harvest. Solar will stretch the runtime but not sustain it.

Tips

  • Keeping internet up during an outage costs very little power, as long as your ISP's equipment down the street still has power too.
  • Running it from the Goal Zero Yeti 500X’s DC port instead of the AC outlet avoids inverter losses: about 35Wh more usable energy.
  • The Goal Zero Yeti 500X uses NMC cells, which are lighter but rated for fewer cycles (typically 500–800) than newer LFP models.
