FAQ
BACKUP POWER QUESTIONS ANSWERED
A standby generator is permanently installed outside your home and turns on automatically within seconds of a power outage — you never have to do anything. A portable generator must be manually started, connected with extension cords or a transfer switch, and runs on gasoline that needs to be stored. Voltex Backup Power installs both permanent standby generators and portable generator hookups for Northern Virginia homes.
Generator sizing depends on your home's total electrical load. For essential circuit backup we recommend 14kW to 18kW. For full whole-home backup in homes under 3,000 sq ft we recommend 20kW to 22kW. For larger homes or homes with multiple HVAC systems 26kW or higher is recommended. We perform a complete load assessment before recommending any generator to ensure you get the right size for your specific home.
An automatic transfer switch monitors your utility power 24 hours a day. When it detects a power outage it automatically disconnects your home from the utility grid and switches to your generator within 10 to 30 seconds — all without any action required from you. When utility power is restored it automatically switches back. Voltex Backup Power installs and wires all automatic transfer switches to code with full permits and inspections.
A complete whole-home generator installation in Northern Virginia typically ranges from $8,000 to $15,000 depending on the generator size, fuel type, transfer switch complexity and any electrical panel upgrades required. We provide free consultations and detailed written quotes with upfront transparent pricing before any work begins — no hidden fees or surprise invoices.
Yes — Voltex Backup Power installs both whole-home generators and battery backup systems including Tesla Powerwall and other major battery storage brands. Battery backup systems are ideal for shorter outages and homes with solar panels. For longer outages or homes without solar a whole-home generator is typically the more reliable solution. We help you choose the right backup power solution for your specific needs and budget.
A standby generator should be professionally serviced once a year — including oil change, filter replacement, spark plug inspection, battery check and load testing. Voltex Backup Power offers annual maintenance plans to keep your generator running reliably when you need it most. Regular maintenance also protects your manufacturer warranty and extends the life of your generator significantly.
