Specifications
Last checked on 11 November 2026. The grey text under each name explains what the value means.
| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 5.0 kWh |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | Not stated on the product page |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | Not stated on the product page |
| ExpansionExtra battery units that add storage to the same system. | Not stated on the product page |
| Power | |
| AC outputThe power it can deliver through its sockets or inverter, in watts. | 3.84 kW continuous power rating |
| Peak outputA short burst above the continuous rating, for example to start a motor. It cannot be held. | 7.68 kW for 3 seconds and 6.14 kW for 10 seconds |
| Round-trip efficiencyThe share of the energy you put in that comes back out. The rest is lost as heat. | 96% DC and 90% AC |
| Backup in a power cutWhether it can keep selected circuits running during a grid outage. | Not stated in the specifications; the page lists an IQ System Controller as a compatible part |
| Solar | |
| Solar inverterTurns the DC power from solar panels into AC for the home. Built in means no separate solar inverter is needed. | None built in: it is AC-coupled and works with Enphase IQ Series microinverters |
| Connection and housing | |
| Dimensions (D × W × H)Depth, width and height of the unit, so you can check that it fits the space and the wall or floor it needs. | 7.4 × 21.7 × 38.6 in, about 188 × 551 × 980 mm (converted from the inches Enphase lists) |
| WeightMatters for lifting, wall mounting and moving it. | 174 lb, about 79 kg |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | Not stated on the product page |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Not stated on the product page |
| Warranty | |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | Not stated: Enphase publishes its limited warranty terms per country |
