Overview & limitations
UPS behaviour depends on the outlet
The North American manual distinguishes designated online UPS outlets with 0 ms transfer from backup UPS outlets with transfer under 20 ms. Use the documented outlet arrangement and confirm appliance compatibility; whole-home transfer is a separate installed configuration.Reviewed manual scope: Complete English online manual; North American electrical column; diagrams identified but no installation design inferredEcoFlow source ↗ · reviewed 2026-09-24

AC input and charging options
The normal AC input accepts 100–120 V/15 A or 200–240 V/12.5 A in charge-only mode. The separate North American power input/output port supports 100–120 V or 200–240 V at up to 30 A.

Two solar input ranges
Low-PV: 30–150 V, 15 A, 1,600 W maximum. High-PV: 80–450 V, 15 A, 4,000 W maximum. Use separate correctly designed panel strings for the two inputs, allowing for higher open-circuit voltage in cold weather.

Optional equipment and installation
Options include the trolley, 0.75 m battery cable, EV X-Stream adapter, generator adapter, 50 Amp Hub, fixing metal tabs and 4G dongle.

Regional manufacturer warranty policy
5 years for the inverter and 5 years for the battery. Original-purchaser coverage starts at delivery, requires proof of purchase from EcoFlow or an authorized seller, and applies to purchase and use in the United States. Buyers outside the contiguous U.S. bear transport costs to and from the contiguous U.S. Normal wear is excluded.

Typical uses for this unit

  • A small laptop charger rated at 65 W is below the published continuous AC output. Check the charger label and count other loads.
  • A 100 W light or device load is below the published continuous output. Available runtime depends on usable battery energy and conversion losses.
  • A small appliance with a running draw below 500 W may fit the continuous output; compressor and motor startup still require a separate surge check.

These are examples, not a runtime promise or a connection approval. Fit My Needs checks your actual appliances with the existing calculator.

Questions about this product

FAQs
Does the base product provide 90 kWh?
No. The selected inverter-plus-one-battery configuration has 6,144 Wh. The 90 kWh claim refers to the expanded three-inverter, fifteen-battery system with Smart Home Panel 2.EcoFlow source ↗ · reviewed 2026-09-24
Can every input be added together?
No. If both the normal AC input and power input/output port are connected, the manual gives priority to the latter. Solar may be combined with the active AC/generator charging route, within the configured system limits.Reviewed manual scope: Complete English online manual; North American electrical column; diagrams identified but no installation design inferredEcoFlow source ↗ · reviewed 2026-09-24
