Why Battery Storage Matters for Arkansas Homes
Arkansas is no stranger to severe weather. The state experiences an average of 40 thunderstorm days per year, frequent ice storms in the winter months, and occasional tornadoes that can leave entire communities without power for days. In 2023 alone, Entergy Arkansas reported over 380,000 cumulative customer outages across eight major storm events. For families that depend on electric medical equipment, work from home, or simply refuse to lose hundreds of dollars in spoiled groceries during every extended outage, home battery storage is no longer a luxury. It is a practical necessity.
But backup power is just one piece of the battery storage equation. A properly configured home battery system also enables you to maximize the value of your solar panels by storing excess daytime production for use during evening peak hours when electricity rates are highest. This practice, known as peak shaving or time-of-use optimization, can reduce your grid consumption by an additional 20 to 40 percent beyond what solar panels alone achieve. For homeowners already generating their own electricity, a battery is the logical next step toward true energy independence.
At Energy Future Arkansas, we are certified installers for the four leading home battery platforms: Tesla Powerwall, Enphase IQ Battery, LG RESU, and Generac PWRcell. Our CEO Marcus Caldwell holds NABCEP certification with a specialization in energy storage systems and has overseen the installation of more than 350 residential battery systems across the state since 2019. We help every client choose the right battery platform, capacity, and configuration for their specific goals, whether that is keeping the lights on during a storm or eliminating their electric bill entirely.
How Home Battery Storage Works
A home battery storage system consists of three primary components: the battery unit itself (a lithium-ion or lithium iron phosphate cell pack housed in a weather-resistant enclosure), a hybrid inverter or battery-specific inverter that manages the flow of electricity between your solar panels, battery, home loads, and the grid, and a smart energy management system that determines when to charge, discharge, and export energy based on your priorities and settings.
During daylight hours, your solar panels generate electricity. Your home consumes what it needs in real time, and any surplus charges the battery. Once the battery is full, additional surplus flows to the grid and earns net metering credits. When the sun sets or during cloudy periods, the battery discharges to power your home, reducing or eliminating the need to purchase electricity from the grid at retail rates.
During a grid outage, the system automatically disconnects from the utility grid (a process called islanding) and continues powering your designated circuits using stored battery energy and ongoing solar production. Modern batteries complete this transition in less than one-hundredth of a second, so fast that most electronics never register the interruption. If you have sufficient battery capacity and solar production, you can operate independently of the grid indefinitely.
All of the battery systems we install include built-in monitoring apps that display real-time energy flow, battery state of charge, solar production, home consumption, and grid import/export data. You can control priorities, set backup reserves, and receive alerts directly from your smartphone. Our team also monitors your system remotely and proactively addresses any performance anomalies.
Pairing Battery Storage with Solar
Battery storage delivers the greatest value when paired with a solar panel system. Without solar, a battery is essentially a backup generator that must be charged from the grid. With solar, the battery charges for free from your rooftop every day, creating a self-reinforcing cycle of clean energy production and storage that minimizes grid dependence year-round.
If you already have a solar system installed, we can retrofit a battery using AC coupling, which works with virtually any existing solar inverter. If you are installing solar and battery together, we use DC-coupled configurations that are slightly more efficient and cost-effective. Either way, the battery qualifies for the 30% federal Investment Tax Credit when paired with solar, which can save you $3,000 to $10,500 depending on system size.
Our engineering team models your combined solar-plus-battery system to determine the optimal battery capacity based on your solar production profile, consumption patterns, and backup power requirements. We size the system so that you achieve the best balance of cost, backup duration, and daily self-consumption without overspending on more capacity than you need.
