EcoFlow Home Backup Kit — Transfer Switch

A transfer switch is the piece that turns a power station into house backup: it lets your DELTA feed real circuits at the breaker panel rather than running cords through the house. This listing carries four different switches, and the right one depends entirely on which power station you own and how many.

Getting this wrong is the most common ordering mistake in home backup, so the table below maps each switch to the systems it's built for. All four require installation by a licensed electrician.

  • Matched to Your Power Station: Four switches covering single and dual DELTA Pro, DELTA Pro 3, DELTA Pro Ultra, and DELTA Max setups.
  • Feeds Real Circuits: Powers your breaker panel rather than requiring extension cords through the house.
  • 125V and 250V Options: The 306A-125/250V and A510A-125/250V switches support split-phase 240V loads, not just 120V circuits.
  • Up to 50A: The A510A option is rated 50A for dual DELTA Pro 3 or dual DELTA Pro Ultra systems.
  • Manual Operation: You switch over when the grid fails — far cheaper than an automatic smart panel.

Which Switch Do You Need?

Switch Voltage / Rating Built For
Transfer Switch 306A1 125V A single DELTA Pro 3 or DELTA Pro
Transfer Switch 306A1 125V A single DELTA Max
Transfer Switch 306A-125/250V 125/250V 1 × DELTA Pro 3, 1 × DELTA Pro Ultra, or 2 × DELTA Pro
Transfer Switch A510A-125/250V 125/250V, 50A 2 × DELTA Pro 3 or 2 × DELTA Pro Ultra

Match the switch to your power station before ordering — they are not interchangeable. The two 306A1 options look identical in the dropdown but are configured differently for DELTA Pro/Pro 3 versus DELTA Max, so read the variant name carefully. If you have 240V loads such as a well pump or an electric range, you need one of the 125/250V switches, not a 125V-only one. Call us at (303) 876-7654 with your power station model and a photo of your breaker panel and we'll confirm the right switch before you buy.

EcoFlow doesn't publish detailed specifications for each switch in this kit — circuit counts, enclosure ratings, and dimensions vary by model and aren't available in a form we can verify, so we haven't listed them rather than estimate. Call us at (303) 876-7654 and we'll get the exact figures for the switch you need. If you'd prefer automatic switchover and per-circuit app control, the EcoFlow Smart Home Panel 2 and Smart Home Panel 3 do that instead — at considerably higher cost, but with no one having to flip a switch during a storm.
