Overview
The Yeti PRO 4000 is Goal Zero's largest portable-rated power station and the most thoroughly documented heavy-duty record in this index: its user guide publishes a full technical specification table including an explicit 0-100% wall-charge time, a pass-through rating, and per-port output limits. Capacity is 3,993.6 Wh of LiFePO4 rated 4,000 cycles to 80%. The inverter delivers 3,600 W continuous pure sine with a 7,200 W surge, shared across four 20 A outlets and a dedicated 30 A TT-30R RV output. Charging is unusually well specified: 1,800 W from AC for a stated three-hour full charge, 3,000 W through a 13.3-150 V high-voltage DC input, and a separate 275 W low-voltage input for single panels. Goal Zero explicitly states the unit is NOT a certified UPS, while documenting an Automatic Power Switching mode — a distinction this index records rather than smooths over.
Variant note: Base standalone Yeti PRO 4000, SKU 37500 (120V). Distinct from the Yeti PRO 8000 (Yeti PRO 4000 paired with a Tank PRO 4000), from the Escape Towable and Drivable RV kits, and from solar-generator bundles pairing the unit with Boulder 200 Briefcase or Nomad 400 panels. The Tank PRO 4000 is an expansion module, not a separate indexed entity.
Data note: Sourced primarily from the official Yeti PRO 4000 user guide (SKU 37500, REV I) Technical Specifications table, checked 2026-07-29, with the official product page used for the waveform statement and the 20 kWh expansion ceiling. Nearly every core field comes from the manual's spec table, so the record is held at high confidence. UPS STATUS RECORDED CAREFULLY: the manual states in its warnings that 'The Yeti PRO 4000 is not a certified Uninterruptable Power Supply and has not been tested to hospital-grade standards or any standards specifically related to medical equipment', while separately documenting an 'Automatic Power Switching' mode with its own manual section and an 'APS Mode Engaged' status icon. upsEpsMode is therefore recorded as 'eps' — an automatic switchover that is explicitly not a certified UPS — rather than 'ups'. This distinction matters for backup recommendations and is deliberately not smoothed over. numberOfAcOutlets=5 counts the four 20 A outlets plus the dedicated 30 A RV output; note the four share a 3,600 W continuous budget rather than each delivering 2,400 W simultaneously. solarInputW=3000 is the High Voltage DC maximum; the separate Low Voltage DC input is capped at 275 W and the two are recorded separately rather than summed, because the manual presents them as distinct inputs with distinct voltage windows. Reaching the full 3,000 W requires Goal Zero combiner cables per the manual's Solar Charging section. weightKg and dimensionsMm are the 'Yeti only' figures; the manual separately publishes 'with Cart' values (57.03 kg, 45.9 cm tall) which are not used here. mpptPresent is null because no official MPPT statement was found.

Use cases
- Large home backup across up to 10 integrated circuits at 3,600 W continuous
- RV shore power via the dedicated 30 A TT-30R output
- Field production and sensitive equipment needing documented pure-sine output
- Fast-turnaround emergency use: a stated 0-100% wall charge in about three hours
Strengths and weaknesses
Strengths
- The best-documented record in this index: the manual publishes an explicit 0-100% charge time, pass-through rating and per-port limits
- 3,600 W continuous pure sine with a dedicated 30 A TT-30R RV output rated to the full 3,600 W
- 3,000 W high-voltage solar input across a wide 13.3-150 V window
- 4,000 cycles to 80% with the retention basis explicitly stated (0.5C, climate controlled)
- Simultaneous charge and discharge documented as a spec-table row, not marketing
Weaknesses
- 52.5 kg for the unit alone, 57 kg with its cart — wheeled, not carryable
- Goal Zero explicitly states it is NOT a certified Uninterruptible Power Supply, so it should not be relied on for equipment that cannot tolerate a switchover gap
- 120 V only: no 240 V output, unlike the F3800, DELTA Pro 3 or DELTA Pro Ultra
- Exceeding 600 W of solar requires Goal Zero series/parallel combiner cables, and the 3,000 W ceiling needs a specific multi-cable arrangement
- 20 kWh expansion requires up to four Tank PRO 4000 modules, sold separately

acInputW | 1800 | AC Input 1800W (90-144V AC, up to 15A) | Official manual (PDF) — Stated in watts directly, so no derivation was needed. A Charge Speed switch can reduce this to 400 W. | high |
acRechargeTimeHours | 3 | Wall Charge Time 0-100% in about 3 hours at 1800W | Official manual (PDF) — Explicitly annotated 0-100% with its input power stated — a genuine full-recharge figure, unlike the partial-charge claims common in this class. | high |
solarInputW | 3000 | High Voltage DC 3000W Max (13.3-150V DC, up to 40A) | Official manual (PDF) — High Voltage DC input maximum. The separate 'Low Voltage DC 275W Max (12.3-28V DC, up to 10A)' input is not summed into this figure — the manual presents them as distinct inputs. | high |
weightKg | 52.5 | Weight (Yeti only) 115.74 lbs (52.5 kg) | Official manual (PDF) — Unit only. The manual separately states 'Weight (with Cart) 125.73 lbs (57.03 kg)', which is not used per the unit-weight-only rule. | high |
