Secure Your Home’s Energy Future with Tesla Powerwall
Smartenergy is proud to be a Tesla Powerwall Premium Certified Installer, making us one of the few companies in Africa with this prestigious certification. We have the largest number of Tesla Powerwall installations across the continent, serving both residential clients and diplomatic missions in South Africa.

The Powerwall is an advanced battery system designed for both homes and businesses, allowing you to store solar energy efficiently. It’s a top-quality, rechargeable lithium-ion battery with smart software and an easy-to-use smartphone app, all at a relatively affordable price. Known for its reliability, the Powerwall can automatically detect a power outage, disconnect from the grid, and restore power to your home so quickly that you might not even notice the outage.
When combined with home solar panels, the Tesla Powerwall stores excess electricity produced during the day, instead of sending it back to the grid. This stored energy can then be used at night or during periods of low sunlight, reducing the need to purchase expensive electricity from utility companies.

Frequently Asked Questions
Have some questions before you get started? Check out our FAQs below or email us at info@smartenergygroup.co.za
What is the Tesla Powerwall?
The Tesla Powerwall is a rechargeable home battery system that stores energy from solar panels or the grid. It powers your home during outages or peak demand times, giving you greater energy control and independence.
How does Powerwall work with solar panels?
Powerwall stores the extra electricity your solar panels produce during the day. This stored energy is then used when the sun isn’t shining—like at night or during cloudy weather—minimizing reliance on the grid.
What’s the difference between Powerwall 2 and Powerwall 3?
Powerwall 3 offers higher power output, integrated solar inverter support, and improved scalability. Unlike Powerwall 2, Powerwall 3 can deliver whole-home backup for larger properties and is better suited for new solar + storage installations.
Powerwall 2: Works with external inverters and has a maximum output of 5 kW continuous.
Powerwall 3: Includes a built-in inverter with higher peak power (11.5 kW), ideal for heavy loads and whole-home backup.
Can I upgrade from Powerwall 2 to Powerwall 3?
Yes, you can upgrade, but Powerwall 2 and Powerwall 3 are not compatible together. To transition, you’ll need to remove or isolate the Powerwall 2 and install Powerwall 3 with its own inverter setup. Smartenergy can assess your current system and recommend the best path for upgrade.
Can I control Powerwall from my phone?
Yes! The Tesla app gives you full visibility and control, track your energy use, check battery status, and adjust settings from anywhere in real-time.
How many Powerwalls do I need?
The number of Powerwalls depends on your home’s energy usage and backup requirements. During your consultation, Smartenergy will evaluate your needs and recommend the ideal setup for optimal performance.
Will Powerwall keep my power on during loadshedding?
Absolutely. Powerwall automatically detects grid failures and switches your home to battery power, ensuring your lights, appliances, and essential devices keep running without interruption.
Can Powerwall work off-grid?
Yes, with the right configuration. While Powerwall is designed for grid-tied systems, it can work in off-grid setups when paired with solar panels and backup generation. Smartenergy can help you build a custom off-grid-ready solution.
What’s the expected lifespan of a Powerwall?
Tesla Powerwalls are built to last, retaining around 70% capacity after 10 years. For backup-only usage, they support unlimited cycles. All units come with a 10-year warranty for peace of mind.
Can Powerwall reduce my electricity bill?
Definitely. Powerwall lets you use more of your own solar energy, reducing what you pull from the grid. This can significantly lower your monthly electricity costs—especially when paired with time-of-use billing.
