BLUETTI AC500 Home Integration Kit
This kit — a sub panel, outlet box, and cabling set — connects an AC500 power station (sold separately) to a home's main electrical panel, enabling automatic backup switchover during an outage and pass-through charging the rest of the time. Available in two configurations: a 120V kit for a single AC500, or a 120V/240V split-phase kit for two AC500 units. Backed by a 1-year manufacturer's warranty.
Choose based on how many AC500 units the install uses.
120V
Connects a single AC500 to the home's main panel. The simpler, more common configuration.
120V / 240V
Connects a split-phase setup using 2 AC500 units, for both 120V and 240V home circuits.
Wires the AC500 into the home's existing electrical system rather than relying on extension cords or manual swaps.
When the grid fails, the AC500 switches on automatically to keep connected circuits powered.
The AC500 charges normally from grid power while connected, staying topped up and ready.
Both kit variants include a 50A outlet box and a sub panel with a 50A inlet, sized for whole-circuit backup.
Choose the standard kit for a single AC500, or the split-phase kit for a two-unit 120V/240V setup.
The split-phase kit adds a communication cable to keep both AC500 units coordinated.
Hassle-free coverage on the kit hardware itself, separate from the AC500's own warranty terms.
Plus lifetime customer support from BLUETTI on this kit specifically.
An AC500 on its own is still a portable power station — plug things directly into it, and it works. This kit changes that relationship: instead of running extension cords or manually plugging circuits into the unit during an outage, the AC500 gets wired into the home's actual electrical system through a dedicated sub panel and 50A outlet box. When the grid goes down, backup switchover happens automatically. The rest of the time, the AC500 charges normally through the same connection — pass-through charging, not a separate charging step.
Two configurations cover different setups: the 120V kit connects a single AC500, while the 120V/240V split-phase kit connects two AC500 units together with an added communication cable, for installs that need both voltage types on separate circuits. Worth flagging directly: BLUETTI's own product page gives two different battery requirements for the split-phase kit — "at least 2 B300S" in one place, "at least 4 B300S" in another. That's a genuine inconsistency in their source material, not something resolved here — confirm the actual requirement with BLUETTI before sizing a split-phase install.

*BLUETTI's own product page states the split-phase kit's battery requirement as "at least 2 B300S" in one section and "at least 4 B300S" in another — a genuine conflict in their source material. Confirm directly with BLUETTI before sizing an install around this number.
No — the AC500 is sold separately. This kit is the sub panel, outlet box, and cabling needed to connect an AC500 (or two, for the split-phase kit) to the home's electrical system.
The 120V kit for a single AC500 covers most standard installs. The 120V/240V split-phase kit is for setups using two AC500 units together to cover both voltage types.
Yes — that's the core function of this kit. Once installed, the AC500 detects a grid failure and switches to backup power automatically, without manual intervention.
Yes — pass-through charging is supported, so the AC500 charges normally from grid power through the same connection when the grid is up.
Given this involves connecting to a home's main electrical panel, installation should be handled by a licensed electrician familiar with local code.
1 year on the kit hardware, described by BLUETTI as hassle-free — separate from whatever warranty applies to the AC500 unit itself.
