The power goes out. It’s dark. Panic sets in. The fridge stops humming, the lights won’t turn on, and your phone’s battery is already low. You thought your solar panels had you covered—but like most homeowners, you’re surprised to learn that standard solar systems shut down during blackouts.
That’s because, without a battery, your panels can’t operate when the grid is down. And even on normal days, once the sun sets, your home switches back to grid power—usually during peak pricing hours.
The Enphase IQ Battery 5P™ device solves both of these problems. This advanced solar battery stores excess energy your panels produce during the day and keeps it ready for use at night, during power outages, or whenever electricity rates spike. With powerful backup capabilities, smart monitoring, and a modular design, it brings true energy independence within reach.
What Is the Enphase IQ Battery 5P?
Launched in 2023, the Enphase IQ Battery 5P device is the fifth-generation battery from Enphase. It delivers twice the power of its predecessor and is designed for whole-home backup, time-of-use savings, and seamless pairing with Enphase solar systems.
The Enphase IQ Battery 5P is the latest home energy storage system from Enphase, designed to pair perfectly with solar panels and Enphase microinverters. Each battery unit delivers 5 kWh of usable energy, 3.84 kW of continuous power output, and up to 7.68 kW of peak output for three seconds—enough to keep essential appliances running when it matters most.
The system uses lithium iron phosphate (LFP) chemistry, which is widely considered the safest and most stable battery technology available for home use.
Why Homeowners Love the 5P
Reliable Power During Outages
The 5P kicks in instantly during blackouts, giving you seamless backup power. Its burst capacity (7.68 kW) allows it to start large appliances like air conditioners, refrigerators, or dishwashers that other batteries may struggle to handle.
Stores Solar Energy for Nighttime Use
Instead of sending excess solar energy back to the grid for minimal credits, you can store it and use it when electricity rates are highest—typically in the evening. This helps reduce your electric bill and increases your solar savings.
Modular and Scalable
Start with one unit and expand as your energy needs grow. The Enphase 5P system supports up to 16 batteries per system, giving you a massive 80 kWh of usable storage if needed.
Smart Monitoring and App Control
The Enphase App lets you track energy production, consumption, and storage in real time. You can customize backup priorities, monitor your savings, and even simulate different outage scenarios to see how long your battery would last.
Safe and Reliable
With LFP chemistry and a rugged design for indoor or outdoor use, the 5P is built to last in all environments. Plus, Enphase’s distributed architecture means that even if one battery unit experiences a problem, the rest of the system continues operating.

How It Compares to Tesla Powerwall
While Tesla’s Powerwall is a well-known option, the Enphase 5P holds its own—and even beats it in key areas:
- Faster, more powerful bursts for starting heavy-duty appliances
- Modular architecture avoids single points of failure
- LFP chemistry is safer and longer-lasting than NMC
- Seamless integration with Enphase solar systems
If your home already uses Enphase IQ Microinverter, the 5P is the most compatible and efficient battery option available.
Is the Enphase IQ Battery 5P right for you?
If you’re a homeowner looking for:
- Protection from blackouts
- Lower electric bills
- Smart energy control
- A reliable and scalable battery bank
…then the Enphase IQ Battery 5P™ device should be at the top of your list.
