Battery storage is an excellent way to increase your home’s energy resilience, storing the extra energy you produce for use later when you need it most. Battery storage can offset peak hour costs, provide additional power at night and on cloudy days, or you can save it for power outages during the most at-risk seasons. Of course, it’s also important to choose the right battery for your home.
Two of the leading solar battery options are the Tesla Powerwall 3 (Tesla PW3) and the Panasonic EVERVOLT series of batteries. Let’s compare the features of the two.
Tesla Powerwall 3 Overview
The Tesla PW3 is a popular choice for solar energy storage and is designed to integrate well with a solar system. Outside of the power specs and durability, its top-selling point is adaptive energy-saving potential, which improves performance based on your historical power usage and 48-hour weather forecasts.

Panasonic EVERVOLT Overview
The Panasonic EVERVOLT comes in three sizes: 10 kWh, 15 kWh, and 20 kWh. It is known for its highly flexible and modular design tailored for higher yields. It is known for its intuitive EVERVOLT mobile app, which transmits dynamic and useful data directly through the battery system. It also has an integrated transmitter that enables safe and rapid shutdown of PV array connections.

Comparison of Key Factors
When comparing the Tesla PW3 with the Panasonic EVERVOLT, the difference in specs and features can help you make the right choice. EVERVOLT batteries come in three capacity sizes, and Tesla PW3s fall in the center of that rage. PW3s stack in larger sets with double the MPPT connections. EVERVOLT has a better mobile app for built-in performance tracking and comes with a longer warranty.
Both are compatible with existing solar panel systems, so you can build them with your solar or add them later. Tesla PW3 has an adaptive smart setting, while EVERVOLTs are easier to control with the app. They are comparable in terms of power output and performance, and both are prepared to function as backup power off-grid.
Choosing the Right System for Your Needs
Which battery system is best for your home? Start by assessing your home’s energy requirements and how a battery storage system can enhance your solar’s ability to meet those needs. Consider your budget and your long-term goals. Evaluate your existing solar or the solar you plan to build. The best way to make the right choice for your solar power storage is with the help of a professional consultation.
