EcoFlow Transfer Switch 306A 125/250V
Product Description
This is EcoFlow's smaller transfer switch, built to pair with a single DELTA Pro Ultra rather than two. It runs at 125/250V, 30A, through a NEMA L14-30 inlet, and gives you six protected circuits — one 2-pole 20A and four 1-pole 15A — to choose what switches over to backup power during a grid outage instead of losing everything on the panel at once.

Who should install this
Like any transfer switch, this splices into your home's main panel and controls which circuits fail over to station power. Have a licensed electrician install it — this isn't wiring to improvise.
What it pairs with
Sized for one DELTA Pro Ultra unit. If you're running two units, EcoFlow's larger A510A 50A switch (paired with the 50 Amp Hub) is the right fit instead — call (619) 238-0205 if you're not sure which one your setup needs.
Common questions about this product
Yes. It connects directly to your home's main electrical panel and controls which circuits fail over to backup power, so it needs to be installed by a licensed electrician rather than tackled as a weekend DIY panel project on your own.
Six total: one 2-pole 20A circuit and four 1-pole 15A circuits, each individually protected by its own breaker, so you and your electrician can decide exactly which loads keep running during a grid outage rather than backing up everything at once.
No — this switch is rated for a single DELTA Pro Ultra only. If you're running two units together, EcoFlow's larger 50A transfer switch paired with the 50 Amp Hub is the combination built specifically for that two-unit setup instead.
This one runs at 30A and pairs with a single DELTA Pro Ultra. The larger A510A switch runs up to 60A at 125V and is built to pair two units together through EcoFlow's 50 Amp Hub, giving a bigger combined backup feed across more circuits.
This switch is specified for pairing with a DELTA Pro Ultra specifically, not the original DELTA Pro. Call (619) 238-0205 with your exact station model and we'll confirm the right transfer switch and hub combination for your particular home setup.
A metal enclosure finished in gray, sized 7.75 × 11.25 × 4.75 in, meant for indoor or otherwise protected mounting near your main panel rather than a fully exposed outdoor installation on an exterior wall somewhere out on the property.
