Tesla Accessory Pack for AC Powerwall -FREE ISSUE PART with Powerwall Packages
Tesla AC Powerwall Accessory Pack — The wiring parts that ship beside the Powerwall rather than inside it.
An AC Powerwall arrives without the parts needed to wire it, because they will not fit in the battery box. They come in a separate UK accessory pack, and the battery cannot be commissioned without it.
Please read before ordering
Please be aware that this item is free of charge when purchased alongside the Tesla Powerwall. To get this part at no cost, please see our package deals.

About the Tesla AC Powerwall Accessory Pack
The pack holds the wiring compartment cover and its four screws, a 4-pin terminal block connector, a second 4-pin connector carrying the 120-ohm terminating resistor, the AC power harness, two Wago 2-position lever nuts, a 32 mm and two 25 mm reducing washers, a 35 mm rubber grommet and a drillable threaded cable gland.
One pack goes with every Powerwall battery, free of charge, when the two are bought together. The second listing here is the same kit sold as a paid spare, for when the original parts have been lost or damaged.
What does this fit?
This is the set of UK-specific parts an AC Powerwall cannot be commissioned without.
Every AC Powerwall needs one of these packs. It is supplied separately because it does not fit inside the battery box, not because it is optional — without it the battery cannot be wired up and will not work.

No. The AC Powerwall cannot be wired without it. It ships separately only because it does not fit in the battery box.
How many do I need?
One per Powerwall battery.
Which of the two should I order?
The free-issue pack, alongside the battery. The spare pack is a paid replacement, for when the original parts are lost.

It terminates the communications bus, which matters once more than one battery is on the system.
