Doncaster Cables Powerwall Connect - AIO Cable Solution PW3 - 50m - 3 x 16.0mm - DATA - SWA
This is an all-in-one Tesla Powerwall connection cable: 3 × 16 mm² power cores plus a data cable and a 12 V supply, inside galvanised steel wire armour, supplied as a 50 m length.
This cable carries the power conductors, the 12 V supply and the data cable a Powerwall needs in a single run, instead of three cables pulled alongside each other. It is designed and tested to Tesla's own guidelines.

Usable energy is the nominal capacity multiplied by the depth of discharge, and both figures are in the Technical Specifications. Most current lithium batteries allow 90% or more.
It needs to appear on your inverter manufacturer's approved battery list and the voltage ranges have to match. Send us your inverter model and we'll confirm compatibility before you order.
Most systems stack in modules up to a maximum number of units per installation, given in the datasheet. Keep to the same model, and buy the full stack together where budget allows.
Only where the IP rating and operating temperature range allow it - both are in the Technical Specifications. Cold reduces usable capacity, so a garage or utility space is usually the better location.
Yes, where the inverter supports timed or forced charging. Paired with a time-of-use tariff this is often the quickest route to a shorter payback.
Warranty terms, and the throughput or cycle count they are based on, are listed under the Warranty tab and in the manufacturer documentation.
