Editorial

Best for, watch out for

Best for

  • Storm-prone homes wanting 2+ days of grid-down resilience
  • Buyers planning to add solar later — the inverter has 5.6 kW of PV input headroom

Watch out for

  • Heavy. Plan for the install footprint and weight ratings before purchasing
  • $/kWh is meaningfully better here than the Best Seller — but only justifies if you actually need the runtime

Common questions

What people ask about the DELTA Pro Ultra X Flagship Bundle

What is actually in the DELTA Pro Ultra X Flagship Bundle?
The bundle ships as a single SKU with all components in one order. The Bill of Materials section above lists every item with its quantity. Each component links to its standalone product page if you want to dig into the detail specs of any single part. Solar panels are not included; see the bundle vendor page for compatible add-on options.
Can I expand the system later?
Yes. Most EcoFlow systems in this class accept additional battery modules up to a manufacturer-stated max. The bundle ships with 4 batteries and 24kWh of capacity. You can buy extra batteries a la carte from the same vendor without rebuying the inverter.
Is this cheaper than buying the components separately?
Yes. Vendors price bundles below the sum of standalone SKU prices to incentivize the larger purchase. The exact savings shifts daily as component prices move; the Bundle savings section above shows the live delta against current observed prices for each component.
Does this hardwire into my home, or plug into an outlet?
The included transfer switch or inlet box is what makes this a hardwired backup install. You will need a licensed electrician to land the inlet box at the panel. After install, you plug the bundle base unit into the inlet to power your selected circuits during a grid drop. The Smart Home Panel adds load prioritization (so the bundle automatically sheds non-critical loads under sustained outage), but also requires a licensed electrician to install at the main panel.
