Maximise Energy Independence With An Advanced Solar Battery System

What Is The Tesla Powerwall System?

The Tesla Powerwall is a rechargeable lithium-ion battery storage system designed for residential use. The system comes with at least one Powerwall battery and a Backup Gateway to help with energy storage, swift backup transition, and monitoring solutions.

The Powerwall stores excess energy generated by solar panels, allowing homeowners to use that stored energy at night, when solar generation is low, and when there’s a power outage. You can charge the system using sunlight (and also using the grid) to keep your household appliances running for extended periods. Powerwall seamlessly takes over as your home’s power source during grid outages.

Tesla Powerwall was first introduced by Tesla, Inc. in April 2015. The initial model had a storage capacity of 6.4 kWh. In 2016, Tesla unveiled the Powerwall 2, a significant upgrade with a doubled capacity of 13.5 kWh and integrated inverters. 

The company continues to refine and expand its energy storage offerings by coming up with Powerwall 3 in 2024. It’s a fully integrated solar and battery system that can supply more power with a single unit to meet the current and future energy needs of your home.

Inbuilt Inverter

Built-in DC-AC inverter simplifies the solar energy system by integrating the conversion of direct current (DC) to alternating current (AC) within the Powerwall unit. This streamlines the installation, eliminating the need for an external inverter and reducing costs.

Tesla Powerwall Installation FAQs

Yes, Tesla Powerwall can save money in the UK by optimising energy use, providing backup during outages, and enabling grid independence. By storing excess solar energy and utilising it when electricity costs are higher, Powerwall contributes to reduced reliance on the grid and potential long-term savings on energy bills *.

The Tesla Powerwall has a warranty that covers a lifespan of 10 years. However, its actual lifespan can extend beyond the warranty period (up to 20 years or more), with the battery system often retaining a significant portion of its capacity for many years.

The Tesla Powerwall system works with or without solar. Without solar, your Powerwall will charge when electricity costs are low and discharge when the costs are high (naturally more effective if electricity rates vary throughout the day). This helps ensure more cost savings in the household.

Determining if the Tesla Powerwall is right for your home depends on various factors, such as your energy needs, location, and goals. If you experience frequent power outages, aim for grid independence to reduce energy costs, or want to maximise solar energy utilisation, the Powerwall will be a valuable addition.
