    Enphase Batteries are popular solar batteries that act as a great battery backup to power your home or business in the Pacific Northwest. 

    Enphase Energy has created these backup power batteries to help homeowners save on energy costs. All while laying the groundwork for several benefits and technologies to track energy usage.

    Are you curious about the benefits of using an Enphase Battery as a backup power solution? This guide focuses on the states of Oregon and Washington.

    Why Use Backup Batteries? Well, Solar Energy is Not Always Reliable

    Because of the unique nature of solar energy in the Pacific Northwest, storing that energy when it is not in use is a unique challenge.

    Bill Gates had to confront this problem when he started investing in energy companies that made batteries. Solar systems are not as easy to store power in as energy produced from things like fossil fuels. Because solar energy is not a constant source.

    The amount of energy you get from your solar panels fluctuates. This is because of the time of day, weather conditions, cloud conditions, and other factors.

    This energy fluctuation problem means that you will need many batteries to store your excess energy. All to make up for when the energy is lacking. These huge batteries will eat up your resources. And could increase your electric bill instead of decreasing it.

    The average US electric customer uses 10,715 Kilowatt-hours (kWh) every year. It requires a massive battery that would weigh more than a ton to store it all when you aren’t getting enough solar power. This number goes up every year as our society relies more and more on electronics in daily life.

    What are Enphase Backup Batteries, and How do They Work?

    Enphase backup batteries are a cluster of batteries integrated with most solar panel systems. They act as a different way to store the energy that your solar panels absorb.

    Enphase backup systems use a technique called “all-in-one-AC-coupled storage systems.” Which increases the homeowner’s solar self-consumption, saving as much as possible by using solar energy.

    AC Coupled Storage System

    Enphase Batteries use a unique configuration known as AC coupled. This configuration means that the batteries, manufactured with a unique micro-inverter, can convert Direct Current (DC) into Alternating Current (AC) power.

    AC power is essential for sensitive electronic devices like computers, and smartphones. And most other technology that is becoming prevalent in homes.

    Lithium Iron Phosphate LFP

    Enphase batteries use Lithium Iron Phosphate instead of traditional lithium-ion batteries.

    With this material, Enphase batteries have more longevity. And the batteries are safer from risks like lithium buildup, fire risk, and degradation.

    They will have better storage capacity over time since they have less of a tendency to degrade.

    Solar Panel Systems that use Enphase ensembles for battery storage will get much more value than traditional solar storage solutions.

    Enphase IQ Batteries

    Enphase describes its line of micro-inverter batteries as IQ batteries. This label means that these batteries are part of the third generation of solar battery storage capacity and that they have no moving parts that will break over time.

    How Do Enphase Batteries Work?

    Enphase batteries work by storing excess solar energy above what you are currently consuming in the Enphase backup grid. That stored energy stays in the grid for later use.

    In the morning, your solar panels will absorb a medium amount of sunlight and use a decent amount of energy. Depending on your usage, you may need to tap into the energy stored from the night before if your solar panels have trouble getting enough energy.

    You will see your most significant spike of incoming solar energy from your solar energy system at midday. Your system will store the excess energy into your Enphase batteries for later use when you overtake your solar input.

    People also have the lowest energy consumption during the middle of the day. As many people are out working, in school, or performing other tasks in the middle of the day.

    During the next afternoon, your battery will fill up and may become full. Depending on your consumption. At this point, you will be able to begin exporting energy back to the grid and save yourself money.

    In the evenings, house members’ energy usage will spike. And you won’t be getting any solar energy to replenish it because the sun is down.

    Over half of the energy usage used in households every day happens during the evening.

    Increasing the Effectiveness of your Solar Panels

    This fact is why having an effective battery like an Enphase battery is essential. Without a good backup battery, you will run out of stored solar energy and have to start using power from your power grid to compensate.

    Using grid power during peak power time will increase the power cost. This cost is because the price of grid power goes up during peak usage hours.

    The process starts over again in the morning. Your results will vary depending on how much solar energy you can hold onto during the night.

    What Are the Costs Associated With an Enphase Battery System?

    Enphase batteries will cost around $3,000. With some models reaching upwards of $7,000 or $9000 for the sale price of the model.

    Another cost that Enphase batteries will have is the installation cost. A trained solar professional will need to install these batteries to ensure they can be grid-tied.

    The installation costs of an Enphase battery system can add an extra $1000 to $2000 to your bill. These installation costs can vary depending on the area of your home and which installer you choose.

    Another potential cost to consider is that some Enphase batteries will be incompatible with some solar panel systems. Especially older ones. While Enphase batteries are compatible with most solar energy systems, some will need an upgrade to accommodate Enphase batteries.

    The cost of upgrading an existing electric panel, or getting a backup subpanel installed for Enphase batteries can add another $1000 or more to costs.

    Are there Incentives Available?

    Yes! In both Oregon and Washington state, they offer incentives for adding batteries.

    What Types of Enphase Backup Battery Systems are Available?

    There are a few different Enphase systems available for homeowners and business owners.

    IQ Battery 3

    The IQ Battery 3 has an energy capacity of 3.36 kWh and includes four with a 1.28 kW power rating. It has a ten-year limited warranty and consists of a fully integrated AC battery system.

    You also get access to a mobile app for monitoring and battery control.

    Enphase Battery Benefits

    Enphase batteries have several benefits that make using them for your solar panel system very appealing.

    Performance Monitoring

    Because Enphase batteries contain micro-inverters made throughout the battery, it makes it much easier to get a more accurate sense of how well the battery is performing.

    You can track individual panel performance from your smartphone and get notifications for when your power performance is less than it should be.

    You will be able to see the effects of a cloudy day versus a sunny day, and you will be able to get clues to investigate other potential problems with your system.

    Certain things like bird droppings, debris, and equipment damage are easier to detect.


    Enphase batteries have safer components that will be more reliable. And they will last longer than traditional solar batteries.

    They are also safer than these traditional lithium-ion batteries. And they will be less likely to catch fire, suffer battery degradation, and fail due to temperature fluctuations.

    This reliable tendency means they will perform better in adverse outdoor weather conditions. Enphase batteries are NEMA 3 rated, and thus certified for practical use in outdoor spaces.

    Emphase batteries contain a semiconductor designed to handle points of failure. And Enphase batteries have passive cooling technology to deal with overheating.

    Final Thoughts

    Backup batteries are crucial for the future of solar energy. Regardless if you use a hybrid solar energy system or another type of solar energy system. They are a great backup plan for when solar isn’t so reliable.

    Suppose people can understand and use these technologies in their solar power generation. In that case, they will be able to save money on their electric bill. And make a positive change for the planet and the people around them.
