Tesla Powerwall 2 is a solar battery for homes and small businesses that stores the sun’s energy and delivers clean electricity when the sun isn’t shining. Combining Powerwall 2 with solar PV improves system benefit and reduces energy demand.
The second edition Powerwall is a complete home energy solution.
As well as enabling customers to store and consume more of their solar energy, lowering energy bills, Powerwall 2 offers numerous additional benefits:
All-in-one solution – Powerwall 2 uses a built-in inverter to convert DC energy to the AC energy required in our homes. This lowers cost and complexity.
Long life – as a result of Powerwall’s liquid thermal control system, system life and performance is increased.
Durable Design – water resistant and dustproof, Powerwall 2 is suitable for internal and external installation.
Always Connected – Powerwall 2 offers a fully online system allowing live monitoring of performance and alerts.
Flexible Installation – as many as nine Powerwall 2 units can be stacked in a single installation.
Affordable – Tesla Powerwall 2 is among the market’s most affordable per kWh battery storage solutions.
