Enphase Ensemble Battery Storage Backup System

Enphase Ensemble w/ Encharge battery storage system

The Enphase Ensemble™ uses Encharge, an all-in-one AC coupled battery storage system that includes embedded gridforming multimode microinverters and one or more Lithium-ion batteries. You can connect multiple Encharge battery storage systems to maximize potential backup for homes. The Encharge 3 storage system for Ensemble provides flexibility to customers to start small and add capacity incrementally.

Common Battery Storage Applications



With self-consumption, you store your excess solar power to use later.

Time of Use Optimization

time of use optimization

Time of use optimization refers to drawing energy from the grid when energy prices are at their lowest, such as late at night. The lower cost energy is stored for use later by the utility when power is more expensive.

Battery Backup

battery backup

Battery backup energy storage is a method one would use to store power to use during a power outage.

AC Coupled vs. DC Coupled Energy Storage System

Energy storage systems come in two varieties:
AC-coupled or DC-coupled.

AC-coupled systems connect to a solar array on the AC side, while DC-coupled systems connect on the DC side. The most obvious advantage of DC-coupled systems is that they allow both the solar array and battery to be served by a single inverter. AC-coupled systems offer equivalent efficiency to DC-coupled systems with advantages in flexibility, reliability, and safety. The Enphase IQ battery is an example of an AC-coupled system, while LG Chem RESU StorEdge is an example of a DC-coupled system.

AC-coupled system advantages

  • Minimizes high-voltage DC indoors
  • Solution can be retrofitted to existing solar installations
  • More incrementally scalable

DC-coupled system advantages

  • One inverter handles all conversion for PV and batteries.
  • DC Power may be tapped into directly
  • Equivalent efficiency to AC-coupled systems

Used Energy Storage Terms

Demand charges are the charges that commercial customers pay for the peak amount of power (load) that they draw from the grid. Demand charges can be a substantial portion of a utility bill; a battery helps lower them by allowing the commercial building to draw from the battery instead of the grid during peak times.

Frequency regulation happens when the utility calls upon batteries to inject power into the grid or take power off the grid to help the grid maintain a stable frequency. Battery owners are compensated for this service.

Lithium ion is a commonly used term to describe any type of lithium-based rechargeable battery. The name refers to lithium ions that are shuttled between cathode and anode when the battery is charged and discharged.

Load shifting is the process of shifting the time when energy is used. For example, running the dishwasher at night to take advantage of off-peak energy prices.

Peak shaving is the process of reducing peak power usage.
