Tesla Powerwall 3 vs. Solar Edge Home Battery: Which Battery Should I Purchase?

February 29, 2024 | Reading Time: 6 minutes

Breaking News: Tesla Powerwall 3 Unveiled

Tesla is officially taking orders for the Powerwall 3, their newest battery technology succeeding the Powerwall 2+. The major difference between these two models is the significant increase of power output now possible with the Powerwall 3. The Powerwall 2 had an output of 7 kW and has now almost doubled with the Powerwall 3 at 11.5 kW.

Comparing Tesla Powerwall 3 and SolarEdge Home Battery Backup

The Tesla Powerwall 3 and the SolarEdge Home Battery backup are the latest solar battery products from these reputable solar technology companies.

While these batteries are very similar, there are a few key areas of comparison that can help you make an informed decision about which battery is best for your system.

Equipment

SolarEdge

The SolarEdge Home Battery is a DC-coupled battery which means it requires a compatible solar inverter, separate from the battery unit, to convert the DC solar electricity into AC household electricity.

SolarEdge batteries are typically installed in new systems because battery and inverter compatibility can be ensured. However, it is possible to add this battery to an existing system as long as the products are compatible.

Tesla

The Tesla Powerwall 3 is a DC-coupled battery that is expandable up to 54 kWh or four total 13.5 kWh Powerwalls linked together.

Performance and Specs

SolarEdge

The SolarEdge Home Battery can hold up to 9.7 kWh of usable energy and can be set up on the floor in a floor stand or mounted to the wall. It weighs 267 pounds, and its dimensions are 31.1 in x 46.4 in x 9.84 in (W x H x D). The battery is protected from water and dust, and can be installed inside or outside. Up to three batteries can be installed per inverter. The continuous power of this battery is 5 kW.

Tesla

The Tesla Powerwall can hold up to 13.5 kWh of usable energy and can be set up on the floor or mounted to the wall. It weighs 287 pounds, and its dimensions are 43.25 in x 24 in x 7.5 in (W x H x D). It can be installed inside or outside and is flood resistent in up to two feet of water. Despite this battery being slightly smaller than the SolarEdge battery, it can hold a greater energy capacity. The continuous power is 11.5 kW. Without the need for a separate inverter, the only restriction on the number of batteries is the electrical panel service capacity.

Maintenance and Service

Both batteries are known to require minimal maintenance throughout their lifespan. If service is needed, SolarEdge’s customer service is rated higher than Tesla’s as you’ll likely experience a longer response time when working with Tesla’s customer service team.

Pricing and Incentives

Tesla

The Tesla Powerwall 3 is typically cheaper than the SolarEdge Home Battery. It is also made in America, qualifying it for the American-made 10% tax credit as affirmed by the Inflation Reduction Act of 2022, saving you even more money.

SolarEdge

The SolarEdge Home Battery is typically more expensive than the Tesla Powerwall 3. Since it’s internationally made, it does not qualify for the 10% tax credit.

Lifespan and Warranty

The lifespan of batteries can range from five to 15 years. This means, if you’re pairing them with a solar system, you’ll need to replace them within your panels’ 25-year lifespan. Factors that determine the lifespan of your batteries include how often you use the batteries, the type of battery you install, and the environment where the battery is stored.

Both the SolarEdge Home Battery and the Tesla Powerwall 3 are backed by a 10-year warranty.

SolarEdge’s warranty is very straightforward; you’re guaranteed at least 70% of the battery’s initial capacity after 10 years.

Tesla’s warranty offers different terms depending on the application used. With the “solar self-consumption / backup only” application, you’re guaranteed your battery maintains a minimum capacity of 70% after 10 years of usage. For all other applications, the battery’s capacity will gradually decrease to 70% either after 10 years of usage or upon releasing 37.8 megawatt-hours.

Is the SolarEdge Home Battery or the Tesla Powerwall 3 Better?

Based on your system’s specific needs, you can determine which battery is a better fit. Ultimately, the SolarEdge Home Battery and the Tesla Powerwall 3 are both top-tier solar products that will store your energy efficiently, ensure a power source in the case of an emergency, and last a long time.
