Backup Power Guides: Portable Generators & Battery Stations
Backup power guides on portable generator hookups (transfer switches, interlocks, inlets) and battery power stations for Northern Virginia homes.
What This Category Covers
When the grid goes down, two practical options keep a Northern Virginia home running: a portable generator wired in safely through a transfer switch or interlock, or a battery power station that delivers silent, fuel-free backup. These guides explain sizing, safe hookups, and what AJ Long Electric supplies and installs.

Backup Power Sizing & Terms
- Portable Generator
- A movable gas or propane unit run outdoors and connected to the home through a transfer switch, interlock kit, or inlet box.
- Battery Power Station
- A silent, fuel-free unit (EcoFlow, Bluetti, Anker SOLIX) that stores energy and powers circuits indoors, recharging from the grid or solar.
- Transfer Switch / Interlock
- The device that safely isolates your home from the grid so a generator or battery cannot backfeed utility lines.
Common Questions
Should I get a portable generator or a battery power station?
A portable generator costs less up front and runs as long as you have fuel, but it needs manual setup outdoors and produces carbon monoxide. A battery power station (EcoFlow, Bluetti, Anker SOLIX) is silent, fuel-free, and safe indoors, with a fixed runtime per charge. Your budget, outage length, and tolerance for refueling decide the winner.
Why does backup power need a transfer switch?
A transfer switch or interlock kit isolates your home from the utility grid before backup power energizes the panel. This prevents dangerous backfeed that could injure line workers and is required by code.

EV Charging
EV charging covers the Level 2 home chargers and circuits that recharge an electric vehicle from your own garage or driveway. These guides walk Northern Virginia drivers through charger selection, the dedicated 240-volt circuit and panel capacity a home charger needs, permitting, and the install costs to expect. A typical Level 2 setup adds roughly 25 to 40 miles of range per hour of charging.
Panel Upgrades
A panel upgrade replaces an undersized or outdated electrical panel with a modern service that safely powers today's larger loads. These homeowner guides explain when an upgrade is required, how to move from 100-amp to 200-amp service, the warning signs of failing or recalled panels, and what permitting and inspection involve. Most Northern Virginia upgrades land between $1,500 and $4,000 depending on amperage and panel location.
Home Safety
Electrical home safety is the set of practices and devices that prevent shock, fire, and arc-fault hazards in a house. These guides cover GFCI and AFCI protection, smoke and carbon-monoxide detectors, overloaded circuits, aluminum wiring, and the inspections that catch problems early. Faulty wiring contributes to an estimated 45,000 home fires in the U.S. each year, which is why proactive checks matter.
Smart Home
Smart home technology connects lighting, outlets, thermostats, and security to app or voice control through reliable, code-compliant wiring. These articles explain smart switches and dimmers, whole-home automation hubs, structured low-voltage cabling, and the electrical groundwork a dependable smart home needs. Done right, a connected home can trim lighting and HVAC energy use by 10 to 15 percent.
Commercial
Commercial electrical work covers the power systems, lighting, and code compliance that keep offices, retail spaces, restaurants, and multi-unit buildings running. These articles address three-phase service, panel and subpanel design, dedicated circuits for commercial equipment, emergency and exit lighting, and the permitting and NEC inspections that commercial properties must pass. Most commercial projects in Northern Virginia must meet the National Electrical Code on a roughly three-year update cycle, so staying current protects both safety and your certificate of occupancy.
Energy Efficiency
Electrical energy efficiency is the practice of cutting wasted power through better lighting, smarter controls, and well-sized circuits. These guides cover LED retrofits, dimmers and occupancy sensors, energy monitoring, and load management that lowers your bill without sacrificing comfort. Switching from incandescent to LED lighting alone can reduce that lighting load by up to 75 percent.
Lighting
Lighting design pairs the right fixtures, layers, and controls to make a space both functional and inviting. These articles cover interior and exterior lighting, recessed and accent fixtures, landscape and security lighting, dimming systems, and energy-efficient LED upgrades. A well-planned layout typically blends three layers of light, ambient, task, and accent, to balance comfort and utility.
Seasonal
Seasonal electrical care is the year-round maintenance that keeps a home's wiring, outlets, and outdoor circuits safe through changing weather. These guides cover holiday lighting loads, storm and outage preparation, surge protection, and warm- and cold-weather inspections tuned to the Mid-Atlantic climate. A few targeted seasonal checks each year head off the outages and hazards that peak during DMV summer storms and winter cold snaps.
Local Services
Local services are the city- and neighborhood-specific electrical guides for homeowners across Northern Virginia and the greater DMV. These articles cover permitting and inspection rules by jurisdiction, common wiring issues in older local housing stock, and what to expect from a licensed electrician in your community. AJ Long Electric serves more than two dozen cities and towns across Northern Virginia, Maryland, and Washington, D.C.
Cost & Pricing
Electrical cost and pricing guides explain what common projects actually cost and the factors that move the final number. These articles break down pricing for panel upgrades, EV chargers, rewiring, lighting, and service calls, plus how labor, materials, permits, and home age affect a quote. As a benchmark, licensed electrical labor in the Northern Virginia and DMV market typically runs between $90 and $150 per hour.
Comparisons
Comparison guides weigh competing electrical products and approaches side by side so you can choose with confidence. These articles contrast options like 100- versus 200-amp service, hardwired versus plug-in EV chargers, portable generators versus battery power stations, and LED versus traditional lighting, with the trade-offs in cost, safety, and performance laid out plainly. Each comparison names the scenario where one option clearly wins so the decision is straightforward.
FAQ
This FAQ collection gives direct, in-depth answers to the electrical questions Northern Virginia homeowners ask most. The articles explain code requirements, safety concerns, project timelines, permitting, and when to call a licensed electrician, written so a homeowner can act on the answer. Every answer reflects current National Electrical Code guidance and real field experience from licensed DMV electricians.
