Frequently Asked Question
What is the main advantage of the Powerwall 3?
Its key advantage is integration. By combining a powerful solar inverter and a battery in one unit, it simplifies installation, reduces equipment clutter, and optimises the flow of energy between your solar panels, battery, and home.
How many solar panels can I connect to it?
The Powerwall 3’s integrated inverter can handle up to 20 kW of solar panels, distributed across three independent inputs (MPPTs). This allows for large, flexible solar array designs, even on complex roofs.
What is LFP chemistry and why is it important?
LFP (Lithium Iron Phosphate) is a type of lithium-ion battery known for its excellent safety, thermal stability, and long cycle life. It does not use cobalt, making it a more sustainable and durable choice for home energy storage.
Do I need a Tesla Gateway?
Yes. The Tesla Gateway is required for all Powerwall 3 installations. It acts as the brain of the system, managing the connection to the grid, providing backup power during an outage, and enabling you to monitor your energy flow. Ceiba Renewables includes this as part of a standard installation.
Is it difficult to install?
The Powerwall 3 weighs approximately 130 kg, so installation requires careful planning and professional handling. Our certified installers will assess your property to determine the best location, whether floor-mounted or wall-mounted, ensuring a safe and secure installation.
