Enphase IQ Battery 5P

What are the Enphase IQ Battery 5P specifications?

A 5.0 kWh AC-coupled battery with grid-forming microinverters built in, designed to be stacked in small increments. It holds 5 kWh of usable energy and delivers 3.84 kW continuously — capacity decides how long you can run, output decides what you can switch on at all.

What matters in Florida

  • A single unit’s 3.84 kW continuous output is generally not enough to run central air conditioning. Florida homes wanting air conditioning on backup typically need multiple units or a different product.
  • The small increment suits homeowners who want essential-loads backup — refrigeration, internet, fans, medical equipment, some lighting — rather than whole-home backup.
  • AC coupling makes this a common choice for adding storage to an existing Florida solar array, particularly one already using Enphase microinverters.
  • In Miami-Dade and Broward, mounting must satisfy High-Velocity Hurricane Zone requirements.

Common questions

Will one IQ Battery 5P run my whole house?

Almost certainly not. At 3.84 kW continuous, a single unit suits essential loads — refrigeration, connectivity, lighting, fans. Central air conditioning generally needs substantially more output, which means multiple units.

Why is there no price on this page?

Because we have no dated, sourced basis for one. Helio41 does not yet have a Florida installation partner price sheet, and installed cost depends heavily on your electrical panel and backup scope anyway.

Can this be added to solar I already have?

Yes — AC coupling is the straightforward retrofit path, because the battery has its own inverter and sits alongside your existing system.
