Not tested by us
We have not tested the Enphase IQ Battery 10C. The figures on this page come from the sources listed at the end of the page, checked on 11 November 2026, and we do not show prices. "Best for" is based on what the maker says the product is designed for, not on our own tests.

| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 10 kWh energy capacity (two 5 kWh battery units per IQ Battery 10C) |
| 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. | Warranty covers up to 6,000 cycles; a cycle-life rating is not stated |
| 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. | 7.08 kVA continuous power rating |
| 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. | Enphase describes backup functionality without extra neutral-forming hardware, and 24 A of load imbalance between L1 and L2 in backup mode |
| Solar | |
| Solar inverterTurns the DC power from solar panels into AC for the home. Built in means no separate solar inverter is needed. | None for panels: it is AC-coupled and integrates 240 V and 120 V microinverters; it works with Enphase IQ Series microinverters |
| Solar and off-grid | |
| Works with solar panelsWhether you can charge it from solar panels. Yes means a built-in solar input or a compatible solar setup; read the detail for the voltage and power limits. | Yes: AC-coupled and integrates 240 V and 120 V microinverters, working with Enphase IQ Series microinverters on the panels. |
| Off-grid useWhether the maker describes it running with no grid connection at all, for example in a cabin, van or off-grid home. Backup only means it covers power cuts but needs the grid the rest of the time. | Partly: provides backup in a power cut; Enphase describes a grid-connected system, not a stand-alone off-grid one. |
| 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. | 14.4 × 28 × 24.5 in, about 366 × 711 × 622 mm (converted from the inches Enphase lists) |
| WeightMatters for lifting, wall mounting and moving it. | 317 lb in total, about 144 kg; lifting weight 126 lb, about 57 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. | 15 years, up to 6,000 cycles |
