Frequently Asked Questions About

What is the difference between Powerwall 3 and Powerwall 3 Expansion Pack?
The key difference between the Tesla Powerwall 3 and the Powerwall 3 Expansion Pack lies in their functionality and components.
The Powerwall 3 Expansion Pack is a DC battery-only unit, designed solely to increase your storage capacity. It must be connected to a primary Powerwall 3 to operate, as it does not include integrated electrical components like an inverter or solar MPPT trackers.
This makes the Powerwall 3 Expansion Pack a cost-effective solution for Tesla Powerwall 3 owners looking to scale up their energy storage.
What is the Tesla Powerwall 3 Expansion Pack Capacity?
Each DC Expansion Pack adds an extra 13.5 kWh of storage capacity, mirroring the capacity of the Telsa Powerwall battery.
What is the Tesla Powerwall Expansion Pack Dimensions
The Tesla Expansion Pack measures 1105 x 609 x 168 mm, matching the height and width of a Powerwall 3 while being slightly slimmer in depth. It is designed to sit neatly alongside or behind the existing unit.
Weighing 118.5 kg, the Expansion Pack can be wall-mounted next to a Powerwall 3 or floor-standing behind the existing unit for flexible installation options.
How much is the Tesla Powerwall 3 expansion Pack in the UK?
At Deege Solar, we’re offering Tesla Powerwall 3 expansion packs starting from £4,950 per unit when installed at the same time as your Powerwall 3. If you’re looking to add them later as a retrofit, prices start from £5,500.
