Enphase Battery Vs Tesla Powerwall 2 (2022)

Enphase Battery Vs Tesla Powerwall 2 (1)

A 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 IQ battery, a premiere Tesla Powerwall alternative.

Here’s what we’re going to get into:

  • Benefits of a solar battery
  • How to assess the right battery for your needs
  • Common terms explained
  • Head-to-head: Enphase Battery vs Tesla Powerwall 2
  • Enphase battery Features
  • Tesla Powerwall 2 Features

Benefits of a solar battery

Why would you want a solar battery? Here are just a few of the benefits:

  • Lower electric bill
  • Protection from power outages
  • Maximize your solar panels

How does a solar battery do all this, you ask? One of the top reasons homeowners have decided to add a battery backup to their solar system is to reduce their monthly electric bill. Solar panels often produce more electricity than a home can use, especially during the day. With a battery backup, you can store excess power for your home to use at night. Not only can you use that power at night, but also during any type of power outage. Homeowners like you want to feel protected from rising electricity costs and natural disasters – that’s why they’re adding a battery to their solar systems.

How to find the right battery for your solar panels

So now, how do you choose the right battery for your needs? There is a lot of information out there and unless you’ve done a ton of research and are technically inclined, it might get confusing, not to mention overwhelming. Don’t worry, we’re about to break it down for you. Here are the most important terms in the world of solar batteries and what they mean: in simple terms. You’re welcome.

What does depth of discharge mean?

Depth of discharge (DoD) just means how much the battery can hold a charge before it needs to be recharged. Like, your cell phone, example. If you had to recharge it every time it said 5%, you would have a 95% DoD.

What this means for you: look for a solar battery that has a high DoD, ideally over 95%.

What is round-trip efficiency?

Round-trip efficiency (RTE) just means how much energy your battery can give you, compared to how much it can store. Using your cell phone as an example, if you were only able to use 70% of your battery each time you charged it, the RTE would be 70%. This is slightly different from DoD in that it measures how much energy discharged compared to how much energy was put into it for each cycle.

What this means for you: since batteries lose efficiency each cycle (we all know this from our cell phone), look for a high RTE for your solar battery to maximize your savings and lifespan.

Battery life: why it matters

Once again, since we all are very aware that batteries lose charge with each cycle, an extremely important factor to consider is battery life, and if the manufacturer provides a warranty.

A typical solar battery can last between 5 and 15 years, depending on how many cycles it goes through. Most leading manufacturers guarantee their batteries with a 10 year warranty.

What this means for you: choose a solar battery from a reputable company with at least a 10 year warranty. That way if anything goes wrong within 10 years, you’ll get a free replacement.

Types of batteries and their chemistry

Another factor you’ll want to consider is the type of battery, as in what is the battery made of. The most common solar battery types are lead acid and lithium-ion.

What’s the difference? Lead acid batteries have been on the market for a long time and they have low DoD as well as a short lifespan. However, they are the least expensive option. Lithium-ion is what most home solar batteries from leading manufacturers are made of. Lithium-ion has a higher DoD and lifespan, and is a lot more compact and lighter than lead acid.

Among lithium-ion batteries, Lithium Iron Phosphate (LFP) is the safest option, compared to Nickel Manganese Cobalt (NMC).

Battery capacity and its factors

A major factor in choosing the right solar battery is how much energy you’ll want to store in your battery. This can depend on a lot of things. For example, how much energy does your house normally consume? How large is your solar panel system? What are your energy goals with a solar system and battery? What appliances and equipment do you want backed up in case of an outage?

All of these factors can be discussed with a professional to help make your decision easier. Find out more.

Let’s get down to what you want to know. Comparing the new Enphase battery: the Encharge 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:

(Video) Tesla Powerwall Vs Enphase Battery

Enphase Battery Vs Tesla Powerwall 2 (2)

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

Enphase Battery Vs Tesla Powerwall 2 (3)Flexible

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: Encharge 3™ and Encharge 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.

Safe

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.

Monitoring

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.

Reliable

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.

Seamless BackupEnphase Battery Vs Tesla Powerwall 2 (5)

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.

Monitoring

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.
