A home solar battery gives you the power to control your home’s energy at night, during outages, and even during peak grid electricity prices. With a solar battery, you can store solar energy that your solar panels produce. But which is the right battery for your needs? Sit back and relax, we’ve got you covered in this handy guide to choosing the right solar battery and the Enphase battery Vs Tesla Powerwall comparison. The Tesla Powerwall 2 which was released in 2016 is contending with the Enphase battery, a premiere Tesla Powerwall alternative.

Enphase Battery Vs Tesla Powerwall 2 Comparison

Let’s get down to what you want to know. Comparing the Enphase battery with the Tesla Powerwall 2, which one is best?

Although it’s difficult to know which battery would be best for your situation, we can go head-to-head with the features between the two batteries and compare some of the standout features that make each one unique.

Here’s the breakdown:

Winning Features of the Enphase IQ battery: a Tesla Powerwall Alternative

Enphase Battery


With the Enphase IQ battery,  you have the option of connecting multiple storage systems to maximize backup potential for whole home backup. The Encharge IQ comes in two different sizes:  IQ 3™ and IQ 10™.

What this means for you: this gives you more flexibility with your specific energy needs. Connect multiple Encharge storage systems to maximize backup potential for whole home backup.


The Enphase IQ is a lithium-ion battery, like most other solar batteries from leading manufacturers. However, the difference with Enphase is Lithium iron phosphate (LFP) chemistry instead of Nickel Manganese Cobalt (NMC).

What this means for you: one of the safest batteries you can purchase: LFPs stay cooler, eliminating the risk of thermal runaway fires. In addition, the Enphase IQ’s cells are safety tested and the battery has passive cooling, which means no moving parts or fans.


With the Enphase app, you’ll be able to easily track your energy consumption.  When you have Enphase IQ inverters you’ll also be able to track solar panel production and consumption in real-time, all in one app. With Storm Guard, you can also be notified of weather directly from the National Weather Service.


Enphase created a unique design that backs up your backup system: multiple microinverters placed in the energy storage unit.

What this means for you: if one microinverter malfunctions, the other microinverters ensure that the system continues to run smoothly.
In comparison, most other battery systems use a single string inverter which means if it fails, the entire battery fails.

Overall, the Enphase IQ is a great Tesla Powerwall alternative. Read more about the Enphase IQ battery.

Winning Features of the Tesla Powerwall 2

Seamless Backup

Tesla Powerwall 2 specs

When the grid goes down, solar energy will continue to power your home and charge your Powerwall, automatically. With Storm Watch enabled, Powerwall can communicate to the National Weather Service and prioritize charging in anticipation of severe weather.

Time-Based Control

If your utility offers Time-of-Use rates, you can use less expensive solar energy you’ve already generated to avoid electrical charges during more expensive rate periods.


Each Powerwall installation includes a complete energy monitoring solution for your home using the Tesla app. You can see how your home both produces and uses energy at any given time.
