SolarEdge Home Battery vs Tesla Powerwall 3

The Powerwall 3 is the stronger all-round pick for most homes. It pairs a 13.5 kWh LFP battery with an 11.5 kW inverter, so it can back up heavy loads and accept up to 20 kW of solar across 6 MPPTs. The SolarEdge Home Battery is a DC-coupled add-on for existing SolarEdge Home Hub or Genesis inverters, with up to 94.5% round-trip efficiency and up to three batteries per inverter. Owners and installers praise the Powerwall's integrated design and simple expansion; the SolarEdge suits homes already committed to its ecosystem.

  • Choose the SolarEdge Home Battery if you already have a SolarEdge Home Hub or Genesis inverter and want DC-coupled storage that stacks up to three units per inverter.
  • Choose the Tesla Powerwall 3 if you want one unit that combines battery and a powerful hybrid inverter, with whole-home backup and room to grow to 54 kWh.

Questions and answers

Which is better for whole-home backup?
The Powerwall 3. Its integrated 11.5 kW inverter can run HVAC and heavy appliances, while the SolarEdge battery's output depends on the inverter it is paired with.
Which lasts longer?
The Powerwall 3 carries a 10-year warranty with 70% minimum capacity retention and uses LFP chemistry, which is known for long cycle life. SolarEdge does not publish a comparable retention figure in the listed specs.
Can I add the SolarEdge battery to a Tesla system?
No. The SolarEdge Home Battery only works with SolarEdge single-phase Home Hub and Genesis inverters. The Powerwall 3 works with new or existing solar through Tesla-certified installers.
Is the Powerwall 3 worth stepping up to over the SolarEdge battery?
If you are building a new system or want one box with a strong inverter and room to expand, yes. If you already own a SolarEdge Home Hub or Genesis inverter, the SolarEdge battery avoids replacing equipment.
Which is more efficient?
The Powerwall 3, at 97.5% round-trip efficiency versus up to 94.5% for the SolarEdge Home Battery.
How much storage can each reach?
The Powerwall 3 expands to about 54 kWh across up to 7 units. The SolarEdge Home Battery allows up to 3 batteries per inverter.
