Why Choose the Enphase IQ Battery 5P

The “5P” solves the biggest challenges of residential storage. Unlike previous models that relied on wireless Zigbee communication, the 5P uses a hardwired Control Cable system, eliminating connection drops and ensuring instant response times. Furthermore, it boasts a massive power output for its size. A single 5P unit can deliver 3.84 kW of continuous power, meaning you need fewer batteries to start heavy loads like air conditioners or well pumps compared to competitors.

Benefits of IQ Battery 5P

• Double the Power: With a continuous output of 3.84 kVA, one 5P battery provides nearly the same power as two of the older IQ Battery 10 units. It is designed to start heavy motors and appliances effortlessly.

• Wired Reliability: The move to wired communication means no more signal interference. Your system will stay online and responsive regardless of Wi-Fi noise or distance between components.

• Industry-Leading Warranty: Enphase backs the 5P with a massive 15-year warranty (standard), significantly longer than the 10-year standard offered by most other battery manufacturers.

• Modular Design: You can start with one 5kWh unit and stack up to 16 units (80 kWh) per system, allowing for perfectly sized energy storage that grows with your needs.

Frequently Asked Questions

Q1: Does this work with older Enphase systems (M-Series or IQ7)?

The IQ Battery 5P is optimized for the Enphase Energy System 3.0, which typically utilizes IQ8 series microinverters and the System Controller 3. Retrofit compatibility with older series is possible but requires specific system controllers and configurations.

Q2: What is the difference between this and the IQ Battery 10T?

The 5P is physically smaller but much more powerful per kWh. The 5P uses wired communication (vs. Zigbee wireless on the 10T) and delivers 3.84 kW continuous power (vs. 3.84 kW for the much larger 10T). Essentially, the 5P is faster, stronger, and more reliable.

Q3: How many 5P batteries do I need to run my A/C?

Because of its high surge capability (7.68 kVA peak), a system with just two IQ Battery 5P units can typically start and run a 3-ton or 4-ton central air conditioner (assuming a soft starter is installed), whereas you would have needed much more capacity with older models.

Q4: Can I mount this on the floor?

Yes. While it comes ready for wall mounting, an optional Floor Mount Pedestal kit is available if your walls cannot support the weight or if you prefer a ground-standing installation.

Q5: What does “1P-NA-DOM” mean?

“1P” refers to single-phase (standard residential). “NA” stands for North America (grid standards). “DOM” typically indicates units manufactured or assembled to meet specific domestic content requirements or supply chains.
