Solar Battery Backup Systems
When all else fails power your life with a solar battery
A grid-tie battery back-up system provides a dual purpose. When the grid goes down, as can happen during a storm, service failure or natural disaster, your system’s battery bank kicks in to provide reliable power for you and your family. When the utility grid is up and in working order, depending on your utility's rate structure, a solar battery can offset your energy costs when electricity rates are at their peak.
Make your home Always-On with Enphase Ensemble
Power outages across the U.S. have been getting worse. Our grid infrastructure is over 100 years old and can’t keep up with our increasingly plugged-in society or natural disasters. While generators offer some relief in the face of a blackout, they’re dirty, noisy, dangerous and costly to operate. Traditionally, when the grid goes down, you lose power – even if you have solar power. Until now, thanks to Ensemble solar battery technology from Enphase Energy.

Enphase Ensemble Components
Encharge 10 storage system
The Encharge 10 all-in-one AC-coupled storage system, comprised of three base Encharge 3 storage units, provides a total usable energy capacity of 10.1kWh and twelve embedded grid-forming microinverters. Connect multiple Encharge 10 storage systems to maximize backup potential for whole home backup.
The Encharge 3 all-in-one AC-coupled storage system provides a total usable energy capacity of 3.4kWh and four embedded grid-forming microinverters. It provides great flexibility in starting small and adding incremental capacity.
The Enpower smart switch connects the home to grid power, the Encharge storage system and PV. It provides microgrid interconnection device (MID) functionality by automatically detecting and seamlessly transitioning the system from grid power to backup power in the event of a grid failure.
The wireless communication kit enables direct communication between Encharge, Enpower, and IQ Envoy. It uses 2.4 GHz and 915 MHz frequencies in parallel for maximum reliability. The kit will be connected to one of the USB ports on the IQ Envoy.
The IQ combiner consolidates interconnection equipment into a single enclosure and streamlines PV and storage installations by providing a consistent, pre-wired solution for residential applications. Install the new communication kit in any IQ combiner to enable wireless communication with Encharge and Enpower. Installation of the cellular modem is required unless already present in the IQ combiner. This ensures the best performance of your system.
Ensemble technology for battery backup configurations is fully compatible with IQ 7™ and IQ 6 series microinverters, making retrofit upgrades as simple as new installations.
Enphase Enlighten helps you manage your Enphase Home Energy System with a computer or smart phone. The Enphase Enlighten mobile app, you can check your system’s status at-a-glance without scrolling and still dive into the details of your system’s health and performance, per-panel production all while on-the-go.You can view overall energy and per-panel energy production data within a single click as well as overviews of your energy consumption and energy storage.

Common system configurations
Enphase Ensemble systems support whole home or partial home backup configurations.
Whole home backup
In the whole home (main load panel) backup configuration, Enpower smart switch is installed on the line-side of the main load panels rated up to 200A. This allows a properly sized Ensemble technology system to provide power to all loads in the main load panel in the event of a grid outage. In this configuration, the Enpower smart switch can be configured with a main breaker to act as the service disconnecting means. The solar PV system can be interconnected to the Enpower smart switch on a dedicated breaker or may be interconnected to the main load panel. This configuration typically supports larger PV and storage system sizes and may allow avoiding expensive utility service and/or main service panel upgrades.
Partial home backup
The Enphase Enpower smart switch can also be installed on the load side of the exiting main load panel or service equipment. This configuration can be used when the Ensemble technology system is configured to provide backup to a number of pre-selected load circuits. This configuration is recommended when Encharge storage systems with smaller energy and power capacity and some basic load backup is desired, or when existing constraints prevent main panel backup or other installation methods.
Q: During a grid outage will my Enphase Ensemble system automatically switch to backup during grid outage?
A: Yes! Enphase Ensemble system is an autonomous system that automatically detects grid outages and transitions your home to backup power.
Q: How big of a system do I need to back up my home?
A: Please contact us to get an estimate of the required system size for your home. A solar advisor will review your energy needs and lifestyle to help determine the best system size for your home.
Q: Will my solar PV system continue to produce power when there is a grid outage?
A: Absolutely! Thanks to the Encharge storage system and Enpower smart switch, your solar PV system is capable of generating power and providing backup during grid outages.
Q: Do I need to reduce my energy consumption during a grid outage?
A: We recommend that you manage your energy consumption during an outage in order to reserve power for the most essential items in your home. The Enphase Enlighten mobile app will provide you with real-time energy availability and consumption monitoring to help you manage your energy usage during an outage. Your Go Green Solar tech support representative can help you with identifying the loads that need to be backed up and configuring the appropriate settings.
Q: Is Enphase Ensemble technology safe?
A: Yes! We have designed and developed Ensemble technology to be extremely safe. Batteries used in Encharge storage systems are based on LFP chemistry (also known as lithium iron phosphate). Ensemble technology is an AC-coupled solution, which is inherently safer than high-voltage DC products.
Q: Where are Enphase Ensemble system components typically installed?
A: Components can be installed in your garage, basement or on the outside of your home, depending on various factors. Your solar advisor will help determine the best location in your home.
Q: What is the length of warranties for Enphase Ensemble technology system components?
A: The Enphase Encharge storage system and Enpower smart switch are covered with a 10-year limited warranty. Enphase IQ microinverters are covered by a 25-year limited warranty. You’ll have the peace of mind knowing that every product is manufactured and protected by a single company, Enphase.
