Power outages in the Aiken area are a fact of life. Summer storms, ice events, and aging grid infrastructure can leave your home without electricity for hours or even days. A home battery backup system stores energy so your essential circuits keep running when the grid goes down -- no noise, no fuel, no manual startup required.

Battery backup systems like the Tesla Powerwall and Enphase IQ Battery work silently and automatically. When the grid fails, your battery detects the outage and switches over in milliseconds. Lights stay on, refrigerators keep running, and medical equipment continues operating without interruption. If you have solar panels, your battery can recharge from the sun during an extended outage, giving you days of independent power instead of hours. Unity Power & Light installs and configures home battery backup systems throughout Aiken, SC and surrounding areas, handling every aspect of the electrical work from panel integration to commissioning.

What We Install

We install the leading residential battery platforms and handle the full electrical integration for each system.

Tesla Powerwall

The Powerwall provides 13.5 kWh of usable capacity with a 7 kW continuous output. We mount the unit, wire it to your main panel through the Tesla Gateway, and configure the system for whole-home or partial-home backup based on your priorities.

Enphase IQ Battery

Enphase batteries are modular, allowing you to start with a single unit and add capacity over time. We install the battery enclosure, connect the microinverter bridge, and integrate the system with your existing Enphase solar equipment if applicable.

Whole-Home Battery Backup

For homeowners who want every circuit covered, we design systems with multiple battery units and a transfer switch configuration that backs up your entire electrical panel. No choosing between the refrigerator and the HVAC system.

Solar-Plus-Storage Integration

If you already have solar panels or plan to add them, we connect your battery to the solar system so excess daytime generation charges the battery instead of going back to the grid. During outages, the solar array recharges the battery directly.

Load Management Panels

Most battery systems cannot power every circuit simultaneously. We install a dedicated load management panel (critical loads panel) that prioritizes the circuits you care about most -- refrigeration, lighting, medical equipment, internet, and security systems.

Existing Panel Upgrades

Many Aiken homes need a panel upgrade before a battery system can be installed. If your current panel lacks space for the required breakers or does not meet current code, we upgrade the panel as part of the battery installation project.

Our Installation Process

1

Site Assessment and System Design

We evaluate your electrical panel, available mounting locations, and energy usage patterns. We determine which circuits you want backed up, calculate the required battery capacity, and design the system layout. If you have solar, we assess the inverter compatibility and interconnection requirements.

2

Permitting and Utility Coordination

Battery installations in Aiken County require electrical permits and utility notification. We handle the permit application, coordinate with Dominion Energy or your local utility for any required interconnection agreements, and schedule the inspection.

3

Electrical Installation

We mount the battery unit, install the gateway or transfer switch, wire the critical loads panel, and connect everything to your main electrical panel. For solar-integrated systems, we connect the battery to your solar inverter and configure the charging logic.

4

Commissioning and Testing

We power up the system, run a full charge and discharge cycle, simulate a grid outage to verify automatic switchover, and confirm all backed-up circuits are functioning. We walk you through the monitoring app and explain how the system behaves during different scenarios.

Why Professional Installation Matters

Home battery systems involve high-voltage DC circuits, utility interconnection, and automatic transfer switching. Professional installation is not optional -- it is essential for safety and warranty compliance.

High-Voltage DC Safety

Battery systems operate at 48V to 400V DC depending on the platform. DC circuits behave differently than household AC wiring and require specific overcurrent protection, disconnect switches, and wire sizing. Improper DC wiring creates fire and shock hazards that standard AC circuit breakers will not protect against.

Utility Interconnection Requirements

Battery systems that interact with the grid must comply with utility interconnection standards. This includes anti-islanding protection so your system does not backfeed the grid during an outage, which could electrocute utility workers. We configure the system to meet all utility and NEC requirements.

Rapid Shutdown Compliance

NEC 2020 requires rapid shutdown capability for battery and solar systems. In an emergency, firefighters need to de-energize rooftop and exterior equipment quickly. We install rapid shutdown equipment and label all components according to code so first responders can work safely.

Warranty and Incentive Eligibility

Tesla, Enphase, and other manufacturers require installation by a licensed electrician to honor the product warranty. Additionally, federal tax credits and any state incentives for battery storage typically require permitted, inspected installations. DIY or unlicensed work can void both the warranty and your eligibility for financial incentives.

Battery Backup Installation Pricing

Unity Power & Light provides flat-rate pricing for battery backup installation. The total cost depends on the battery platform, number of units, and the complexity of the electrical integration.

Single battery unit (Tesla Powerwall or equivalent): $12,000 - $16,000 installed
Dual battery system (whole-home backup): $22,000 - $30,000 installed
Critical loads panel installation: Included with battery installation
Panel upgrade (if required): Additional $1,500 - $3,000

Federal tax credits may cover up to 30% of the total installed cost for qualifying battery systems. We help you understand which incentives apply to your installation. Pricing includes all electrical work, permitting, and commissioning.
