Enphase IQ Battery 5P vs SolarEdge Home Battery

The Enphase IQ Battery 5P is the safer pick for most homeowners: AC-coupled, cobalt-free LFP, 15-year warranty, and 3.84 kVA continuous with 7.68 kVA surge from six built-in microinverters. The SolarEdge Home Battery is DC-coupled, so it only makes sense if you already run a SolarEdge Home Hub or Genesis inverter, where it reaches up to 94.5% round-trip efficiency and stacks up to three units. Owners report the Enphase units arrive as described and work well; the main complaint is a rare dead board and slow warranty handling. Neither is a DIY install.

  • Choose the Enphase IQ Battery 5P if you want an AC-coupled battery that works with most existing solar systems, uses safe LFP chemistry, and carries a 15-year warranty.
  • Choose the SolarEdge Home Battery if you already have a SolarEdge Home Hub or Genesis inverter and want DC-coupled efficiency with up to three batteries per inverter.

Questions and answers

Which is better for backup power during an outage?
The Enphase 5P publishes 3.84 kVA continuous and 7.68 kVA for 3 seconds, enough to start a well pump or AC. SolarEdge does not publish surge figures, so Enphase is the clearer backup choice on paper.
Which lasts longer?
Enphase backs the 5P with a 15-year limited warranty and uses LFP chemistry, which tolerates daily cycling well. SolarEdge does not state a warranty term in the listing, so compare the written warranty before you commit.
Can I add the SolarEdge battery to my existing Enphase system?
No. The SolarEdge Home Battery is DC-coupled and only works with SolarEdge Home Hub and Genesis inverters. The Enphase 5P is AC-coupled and fits most existing solar setups.
Is the Enphase 5P worth stepping up to over a smaller battery?
If you want whole-home backup, one 5 kWh unit is modest. Plan for two or more units, or size around critical loads. The 7.68 kVA surge helps, but capacity still limits runtime.
How many batteries can I stack?
SolarEdge allows up to 3 batteries per inverter. Enphase scales by adding more 5P units on the AC side, so the limit depends on your panel and wiring.
Do either need a special inverter?
Enphase has microinverters built in, so it works with most AC-coupled systems. SolarEdge needs its own Home Hub or Genesis inverter, which is the deciding factor for many buyers.
