Full Energy Independence
Full Energy Independence configurations with M Series Microinverters provide homeowners with power for running appliances during a grid outage. This configuration is the perfect solution for homeowners who want to install a new microinverter system or don’t want to be constrained by any ratio between the PV and battery arrays.
Overview
In this configuration, the Enphase Energy System provides all-day backup using M Series Microinverters and IQ Batteries. The system must have at least 10 kWh of IQ Batteries installed. To maintain stability, no greater than 150% of the IQ Battery continuous power capacity (in IQ PV capacity) can be wired into the IQ System Controller.
Components
All the important parts you’ll need for the M Series Full Energy Independence configuration.
M215/M250 Microinverter
Enphase Energy Systems with M215 or M250 Microinverters are fully compatible with IQ Batteries, making retrofit upgrades as simple as new installations.
IQ Battery
The Enphase IQ Battery all-in-one AC-coupled storage system is reliable, smart, simple, and safe. It has a total usable energy capacity of up to 10.08 kWh and multiple embedded grid-forming microinverters with a 3.84 kW power rating. With two different sizes, installers can quickly design the right system size to meet the needs of their solar customers.
IQ System Controller 2
The Enphase IQ System Controller 2 connects the home to grid power, IQ Batteries, and solar panels.
IQ Combiner 3C-ES
The IQ Combiner 3C-ES consolidates interconnection equipment into a single enclosure and streamlines PV and storage installations by providing a consistent, pre-wired solution for residential applications. Included is the new Communications Kit to enable wireless communication with IQ Batteries and the IQ System Controller.
IQ Combiner 4C
The IQ Combiner 4C consolidates interconnection equipment into a single enclosure and streamlines PV and storage installations by providing a consistent, pre-wired solution for residential applications. Included is the new Communications Kit to enable wireless communication with IQ Batteries and the IQ System Controller 2.
IQ Load Controller
While off-grid, the IQ Load Controller helps power your critical loads longer by shedding nonessential loads and loads that cannot be supported at current level of power generation. It can also help ensure the right solar-to-storage ratio for an off-grid system.
Communications Kit
The Communications Kit enables direct communication between the IQ Battery, the IQ System Controller, and the IQ Gateway or IQ Combiner box. It uses 2.4 GHz and 915 MHz frequencies in parallel for maximum reliability.

Important tips
-
IQ Gateway software version 6 or later can be managed only with version 3.24 or later of the Enphase Installer App. Be sure to update your Enphase Installer App in the Apple App Store or Google Play Store before installation.
-
Full Energy Independence backup systems support up to four essential load circuits. This requires the installation of two IQ Load Controllers to control all four load circuits.
-
Full Energy Independence backup systems with M215 or M250 Microinverters are compatible with the IQ System Controller 2 or the IQ System Controller (formerly known as Enpower).
-
Full Energy Independence backup systems with M215 or M250 Microinverters require a battery array 150% the size of the PV array. A smaller battery array will require the PV array to be split.
