Tesla has introduced the Powerwall 3 home power backup system. It differs from similar installations of previous generations in that it supports higher power and has a built-in inverter for solar panels, making it easier to connect them to the system.

The dimensions of the updated Powerwall 3 battery are 110 × 61 × 19.3 cm, the weight is 130 kg. Visually, the new product has changed slightly compared to its predecessors. From the obvious: the Tesla lettering was replaced with a logo in the shape of the letter “T”. The capacity of Powerwall 3 is 13.5 kWh, which is the same as Powerwall 2. However, the output power has increased from 10 kW to 11.5 kW.
Powerwall 3 has an integrated inverter that supports six solar panels. The same Powerwall Plus model, as The Verge writes, only offers the connection of four. The energy conversion efficiency of the Powerwall 3 inverter is stated to be 97.5%.
Powerwall 3 does not support connecting third-party solar inverters and is not compatible with previous generation Tesla batteries such as the Powerwall 2. Additionally, it is unclear whether Powerwall 3 supports connecting commercial solar panels for previous-generation systems, The Verge notes.
The ability to combine multiple Powerwall 3s allows you to increase the total system capacity to 40.5 kWh. Powerwall 3 claims a guaranteed lifespan of 10 years.
The company did not provide any information about the cost of the Powerwall 3 battery. The first shipments of Tesla’s new home backup system will have to wait until 2024, but in the meantime, through October 31, the company is offering a $500 discount on the purchase of Powerwall 2 and Powerwall Plus batteries with or without solar panels at.
