Enphase Encharge 10 vs Tesla Powerwall – A Side by Side Comparison.

Micro Technology to Eliminate a Single Point of Failure

Enphase is the only company in the world to place multiple microinverters in every battery. That means if one microinverter in the battery fails, the battery will still remain functional until repairs can be made.

Tesla Powerwall contains a “single point of failure” system. This means if one thing malfunctions the whole battery shuts down, and is unusable until it is removed from the home and shipped off for repairs, resulting in weeks of no battery storage.

All-in-One Support

The Enphase Encharge 10 is designed, manufactured, and supported by a single company, making it easier for homeowners to get the support they need, when they need it.

The Tesla Powerwall is designed by assembling varied components from separate manufacturers, which will send homeowners on a wild goose chase when something needs to be fixed.

FEMA has recognized the multiple microinverter design as superior in terms of reliability, and therefore recommends Enphase products to homeowners.

Tesla Powerwall has a single point of failure design, and therefore is not recommended by FEMA.

Warranty

Enphase offers a 15 year warranty on all of its battery products, as well as a 25 year warranty on solar microinverters!

Tesla only offers a 10 year warranty on both their battery and solar inverter products.

Battery Chemistry

The Encharge 10 battery uses a Cobalt-free lithium iron phosphate (LFP) battery chemistry. This makes thermal runaway impossible, and in turn makes them the safest battery for residential use.

The Tesla Powerwall uses a nickel-manganese-cobalt (NMC) battery chemistry. This makes them prone to thermal runaway if punctured or if the cooling system fails. Thermal runaway is the term used when a battery overheats, potentially causing a fire or an explosion, so it’s safe to say you don’t want this happening to your home.

UL 9540A Battery Safety Certification

Enphase Encharge 10 achieved the most rigorous testing certification for home energy storage. The Encharge is tried and true!

The Tesla Powerwall does not have this certification.

Lacks Toxic Elements

The Encharge 10’s cobalt-free lithium iron phosphate (LFP) battery does not contain any toxic elements and is landfill safe.

The Tesla Powerwall’s nickel-manganese-cobalt (NMC) battery contains elements known to potentially cause acute toxicity.

Conflict-free Chemistry

Cobalt-free chemistry avoids any global impact on abusive mining practices.

Cobalt mining is known to have a high human cost, including in the Democratic Republic of Congo.

Can Add More Storage Later

Up to 4 Encharge 10 units can be stacked per system.

Up to 6 units can be stacked per system.
