Confirmed 2 years directly from Goal Zero’s official warranty page for this specific “Core” SKU — note this is shorter than the 5-year tier Goal Zero advertises for its unqualified “Yeti 500” 6th-gen naming, so the “Core” suffix appears to matter.

At 500W continuous and 1000W surge, it cannot reliably start a typical well or sump pump motor. Its 499Wh battery runs a 75W CPAP with a heated humidifier for roughly 5 hours and a 100W mini-fridge for roughly 3.7 hours, after a 25% AC-inverter efficiency loss. Its maximum solar input is not confirmed in this project's research.
Can the Goal Zero Yeti 500 Core Run It? (Surge & Runtime Check)
Each row runs this unit's confirmed specs against that appliance's running watts and startup surge, then works out how long the battery would last at that load. Of these twelve: 4 safe, 0 tight, 8 overloaded.

Runtime applies the same 75% AC-inverter efficiency factor used across this site. Where an appliance cycles rather than running flat out — fridges, pumps, air conditioners — the second figure is the longer real-world runtime at its duty cycle. A blank runtime means the unit cannot run the load at all, so there is nothing to calculate. Appliance figures are typical for the class, not measurements of your specific model: check its nameplate where the margin is close.
☀️ Solar Charging the Goal Zero Yeti 500 Core
Maximum solar input is not confirmed for this unit in our dataset, so we are not publishing a panel recommendation for it. Connecting panels above the rated input voltage can damage the charge controller, and that is not a figure worth guessing at — check the manufacturer's own specification before buying panels.
Pros & Cons
- Confirmed pure sine wave inverter — safe for CPAP and other sensitive electronics
- Not expandable — the capacity it ships with is the capacity you keep
- 1000W surge is below what a typical sump pump or standard window AC needs to start
- Shorter 2-year warranty than most competing units in this dataset
Who Should Avoid This
Look elsewhere if any of these matter to you: not expandable — the capacity it ships with is the capacity you keep; 1000W surge is below what a typical sump pump or standard window AC needs to start; shorter 2-year warranty than most competing units in this dataset.
Verdict: where the Goal Zero Yeti 500 Core fits
Its strongest scores in this dataset are for CPAP.

- price_current: STILL NOT FOUND after a second dedicated search pass — every search for 'Yeti 500 Core' pricing was dominated by results for the sibling 'Yeti 500X' instead. This may mean Core is a less common/regional SKU name rather than the primary current retail listing — worth confirming the model naming itself is still accurate before further attempts, not just retrying the same search.
- solar_input_max_w: not stated in this pass — only generic charge-time-per-panel-size guidance found, not a max wattage spec
- note: a separate model, Yeti 500X, exists with different specs (300W/600W surge, 505Wh, 12.9 lbs) — do not confuse the two when sourcing further data
