IQ Battery is charged with the power produced on all phases within the permissible limits determined by the local grid operator's phase imbalance limitations.

Commissioning a System with the Enphase Installer App

How to create a new system in the Enphase Installer App

How can I add users and provide them with access to view my system performance?

Does Enphase IQ Battery support PV systems with all models of third-party string inverters?

Enphase IQ Battery is compatible with all models of string inverters.

Does the grid-tied Enphase IQ Battery support backup power with a third-party string inverter?

Grid-tied IQ Battery will work only when a stable grid is available. It does not support backup operation.

How many IQ Batteries can be installed with a third-party PV-coupled energy system?

Up to 20 IQ Battery 3Ts can be installed using a single IQ Gateway Metered, provided the installed power capacity is within the limit set by the local grid operator.

Do IQ Batteries require a hybrid or standalone inverter to work with a third-party string inverter?

IQ Batteries do not require a hybrid inverter or standalone inverter because they are AC-coupled products incorporating bi-directional Enphase microinverters.

If a string PV system already has third-party storage, can I still add IQ Batteries?

IQ Batteries cannot be used alongside third-party storage. Enphase recommends using an IQ Battery either with Enphase microinverters or a recommended third-party string inverter.

How do I add third-party string inverter details in Enphase Energy System?

Third-party inverter details will be added by the installer during commissioning using the Enphase Installer App and will be visible in the Enphase App.

Which other Enphase components do I need when I install IQ Batteries along with third-party string inverters?

integrate an IQ Battery with an existing third-party inverter, you will need to install an IQ Gateway Metered, Consumption and Production Current Transformers, a wireless Communications Kit and an IQ Relay. In some instances, where the IQ Battery is located at some distance from the IQ Gateway Metered, Range Extender(s) may be required to increase the range of the Communications Kit. In locations without broadband internet, a Mobile connect cellular modem will also be needed.

If a PV system has both a third-party sting inverter and an Enphase microinverter, can I add IQ Batteries?

Currently, Enphase does not support adding the IQ Batteries to this configuration. We expect to support this configuration in the future.

Does Enphase control the operation of the third-party string inverter?

No, Enphase does not control the third-party string inverter.

Does Enphase support module-level monitoring for the third-party string inverter?

No, the Production CT measures the total production from the third-party string inverter. This system-level data is presented in the Enphase App for the system owner.

Can IQ Battery be installed with both single-phase and three-phase third-party string inverters?

Yes, both single-phase and three-phase third-party string inverters are supported.

If I add one IQ Battery, it is connected to a single phase. How does the IQ Battery discharge to provide the power for loads on a different phase?

Charging or discharge to the grid is measured on the aggregate level. IQ Battery will discharge on one phase to support the loads on a different phase within the permissible limits set by the phase imbalance restrictions of the local grid operator.
