What is the Enphase IQ Battery 5P?
The Enphase IQ Battery 5P is a solar energy storage component for solar systems. It stores energy from the panels up on your roof to use whenever you like.
Each IQ Battery has a storage capacity of 5kWh. It has a modular design and can be easily “stacked” (connected together) to increase energy storage capacity. By connecting multiple units, you can expand the storage to meet your specific energy needs. Two IQ Batteries is 10kWh, three is 15kWh, and so on.
This flexibility makes it ideal for homes with varying energy requirements, as you can start with one unit and add more as needed.

How Does the Enphase IQ Battery 5P Work?
The IQ Battery uses the six microinverters embedded within it to convert power and store energy. The microinverters convert the DC power generated by your solar panels into AC power for your home. Everything in your home runs on AC power.
Having six microinverters in the battery decentralises the charge and discharge workflow; if one inverter fails, the battery continues to operate effectively using the other five inverters until it’s repaired.
It has a peak power output of 7.68kW and a continuous power rating of 3.84kW, making it suitable for running power-hungry appliances like air conditioners and pool pumps.
It can provide a continuous power output of 3.84kW and a peak power output of 7.68kW for short periods, allowing it to handle high-demand loads efficiently – stuff like air conditioners and pool pumps.

Benefit #1: Protection During Power Outages
The Enphase IQ Battery 5P is a reliable choice during power outages. Its ability to store and supply energy means you can keep your essential appliances running smoothly when the grid goes down. This includes lights, refrigerators, and medical devices. The battery can provide continuous power, providing electricity for as long as the battery lasts.
When you install an Enphase microinverter solar system on the roof, there’s a compulsory piece of equipment called the Enphase System Controller. Along with the Enphase App, you’ll be able to keep an eye on the energy in your battery and how much power your home is using.
Together, they manage the flow of energy between the main switchboard, the grid, your solar panels, and the battery. You can monitor and control your battery remotely, giving you peace of mind and control over your energy usage even during a blackout.

We recommend navigating to the table of contents and jumping to the heading titled, “Battery Backup and a Three-Phase Connection.” That’s where the most helpful (and least technical), relevant information will be.
Benefit #2: Financial Savings
The Enphase IQ Battery 5P will save you money.
You can use the stored energy during peak hours when electricity rates are highest. This strategy, known as “time-of-use” management, helps you avoid the expensive electricity costs during these peak times. By using your stored solar energy instead of drawing power from the grid, you can significantly reduce your electricity bills.
Additionally, the IQ Battery’s high efficiency will give you the maximum benefit. With an AC round-trip efficiency around 90% and a DC round-trip efficiency of 96%, the battery effectively stores and retrieves energy with minimal losses.
The round-trip efficiency of a battery is the percentage of how much power it holds onto as it converts power into energy for storage and energy into power for use in the home. This means more of your generated solar power is put to good use, enhancing your savings even further.
The Enphase App is also extraordinarily useful for energy savings. The battery’s integration with the Enphase App allows you to monitor your energy consumption and storage in real time. You can see how much energy you’re saving and adjust your usage patterns to maximise savings. This level of control and visibility is everything. You can make informed decisions about your energy use, which leads to greater efficiency and savings.

Benefit #3: Light at Night
Stored energy is particularly useful at night when your solar panels aren’t generating power. Why would you spend money on electricity from the grid when you can use the power harvested from the panels stored as energy in an IQ Battery instead?

Benefit #4: Smart Home Integration with Your Solar System
The Enphase IQ Battery 5P is perfect for smart home technology. Using the Enphase App, you can manage your battery from your smartphone, tablet, or computer, providing you with real-time data on your energy production and consumption. This connectivity means you can optimise your energy use to align with your lifestyle and needs.
The IQ Battery works with other smart devices in your home, creating a cohesive and efficient energy ecosystem. Some examples are smart thermostats, lighting systems, and other fancy-pants appliances.
This integration allows you to manage your entire home’s energy use from one platform. It’s convenient and efficient.

Benefit #5: Reaching Net Zero by 2050
By storing and using solar energy, the Enphase IQ Battery 5P helps reduce your carbon footprint and supports a more sustainable future. Here’s how:
- Reducing Carbon Emissions: Using solar energy stored in the IQ Battery instead of relying on grid electricity significantly lowers your home’s carbon emissions. Grid electricity comes from fossil fuels like coal and natural gas, which release large amounts of carbon dioxide (CO₂) and other greenhouse gases into the atmosphere.
- Safer Chemistry: The IQ Battery uses lithium-iron phosphate (LiFePO4) chemistry. Compared to other types of lithium-ion batteries, lithium iron phosphate batteries are safer and more environmentally friendly. They have a lower risk of overheating. Additionally, lithium iron phosphate batteries do not contain cobalt, which is associated with significant environmental and ethical issues due to mining practices.
- Longer Life: Lithium iron phosphate batteries typically have a longer lifespan compared to other lithium-ion batteries. A longer-lasting battery is more sustainable because it decreases the need for new batteries. Manufacturing solar batteries and selling them consumes resources and energy.
- Grid Support: If the grid is getting help from your battery, that’s less fossil fuel burned to produce electricity. Every little bit helps.
