SKU IQBATTERY-5P-1P-NA-DOM-NFC | 5.0 kWh LFP | 6 × IQ8D-BAT Microinverters | 3.84 kW Continuous | NEMA 3R | Low % Domestic Content | Includes Base Unit, Cover & Wall Bracket
The Enphase IQ Battery 5P (SKU: IQBATTERY-5P-1P-NA-DOM-NFC) is Enphase's most powerful residential battery storage system — an all-in-one, AC-coupled lithium iron phosphate (LFP) battery with six embedded IQ8D-BAT bidirectional microinverters built directly into the enclosure. Delivering 5.0 kWh of fully usable energy capacity, 3.84 kW of continuous single-phase AC output, and a 7.68 kW peak output for 3 seconds, the IQ Battery 5P is engineered to power whole-home essential loads — including high-inrush appliances like air conditioners, water heaters, and pumps — during grid outages. This kit ships complete with the IQ Battery 5P base unit, protective cover, and wall mounting bracket, and qualifies for low percentage domestic content designation under IRS domestic content bonus credit provisions. The system is backed by Enphase's industry-leading 15-year limited warranty covering up to 6,000 charge/discharge cycles.
6 Embedded IQ8D-BAT Bidirectional Microinverters: Unlike conventional battery systems that rely on a single central inverter, the IQ Battery 5P integrates six individual IQ8D-BAT microinverters directly inside the enclosure. This distributed architecture eliminates any single point of inverter failure, delivers cleaner AC output, and enables the system to operate as a true grid-forming inverter — creating its own stable 240Vac microgrid during outages independent of any central controller.
Lithium Iron Phosphate (LFP) Chemistry — Safest Battery Technology: LFP chemistry is inherently more thermally stable than NMC or NCA lithium chemistries — it does not undergo thermal runaway under the same abuse conditions and is significantly less prone to fire or off-gassing. This makes the IQ Battery 5P one of the safest residential battery storage options available, and it is evaluated to UL 9540A for large-scale fire testing with reduced installation separation distance per 2021 IRC, 2021 IFC, and 2023 NFPA 855.
7.68 kW Peak Power + 200% Inrush Capability: A 7.68 kW peak output (for 3 seconds) and 200% inrush current handling capacity allow the IQ Battery 5P to start and run the most power-hungry household appliances — central air conditioning compressors, well pumps, electric water heaters, and refrigerators — without tripping or dropping loads during the brief high-current surge at startup.
Modular — Stack Multiple Units for More Capacity: The IQ Battery 5P is fully modular and stackable. Multiple units can be installed side by side and configured as a single parallel battery system to increase total usable energy capacity and continuous power output — scaling from a single 5.0 kWh / 3.84 kW unit up to a whole-home storage array that grows with future energy needs.
Seamless Enphase Ecosystem Integration: Fully compatible with all IQ8, IQ7, and S-Series microinverter systems and the IQ System Controller 3/3G, the IQ Battery 5P integrates natively into the Enphase Energy System for backup, solar self-consumption, and time-of-use (TOU) optimization modes — all managed through the Enphase App with real-time monitoring and intelligent automated control.
15-Year Warranty / 6,000 Cycles — Industry-Leading Coverage: Enphase backs the IQ Battery 5P with a 15-year limited warranty covering up to 6,000 full charge/discharge cycles — the longest cycle-count warranty available on any mainstream residential battery. At one full cycle per day, this equates to over 16 years of warranted operation, providing exceptional long-term value and investment confidence.
The IQ Battery 5P is an AC-coupled system — it connects directly to the AC wiring of your home's electrical panel rather than to the solar array's DC output. The six embedded IQ8D-BAT microinverters handle all bidirectional DC-to-AC and AC-to-DC conversion internally, meaning the battery charges from any AC source (solar microinverter output, grid, or generator) and discharges clean 240Vac power back to home circuits — no external inverter or charger required.
Grid-Forming Microinverter Architecture: Each of the six IQ8D-BAT microinverters inside the battery is a grid-forming device — capable of establishing and maintaining a stable 240Vac / 60Hz sine wave independently of the utility grid. During a grid outage, the IQ Battery 5P creates its own local microgrid that connected solar microinverters and home loads can operate from, enabling solar production to continue charging the battery even while the grid is down.
Integrated BMS with Active Cell Balancing: The onboard Battery Management System (BMS) monitors individual cell voltage, temperature, and state of charge in real time — actively balancing cells during charge and discharge cycles to maximize usable capacity, prevent over-charge or deep discharge damage, and extend the overall cycle life of the LFP cells to the full warranted 6,000 cycles.
Enphase App — Monitoring, Control & Automation: The IQ Battery 5P communicates with the Enphase IQ Gateway via Power Line Communication (PLC), delivering real-time state-of-charge, charge/discharge rate, and energy flow data to the Enphase App. Homeowners can configure backup reserve levels, self-consumption targets, and TOU schedules directly from the app — and receive alerts for any system events or performance changes automatically.
