Frequently Asked Questions

Everything you need to know about purchasing, installing, and maintaining a commercial/business or home standby generator.

  • 1. How does a home standby generator work?
    A home standby generator automatically detects a utility power outage and restores electricity to your home within seconds. Connected to an automatic transfer switch, it safely powers your selected circuits or your entire home using natural gas or propane until utility power returns.
  • 2. What size home standby generator do I need?
    The right generator size depends on your home's electrical load and the appliances you want to operate during an outage. South Shore Generator performs a professional load analysis to recommend the properly sized generator that provides reliable backup power without unnecessary expense.
  • 3. How often should my standby generator be serviced?
    Most residential standby generators should be professionally serviced once a year or after approximately 100–200 hours of operation. Preventative maintenance includes changing the oil and filters, inspecting the battery, testing the transfer switch, and verifying the generator is ready for the next outage.
  • 4. Can a standby generator power my entire house?
    Yes. Many homeowners choose a whole-house standby generator that powers the entire home, while others select essential circuits to reduce system size and cost. South Shore Generator can help determine the best solution based on your home's electrical demands and budget.
  • 5. How long can a home standby generator run?
    Home standby generators are designed to operate for extended periods during prolonged outages. As long as they have a continuous fuel supply and receive recommended maintenance, they can safely run for days while providing dependable backup power.
  • 6. Why does my business need a commercial backup generator?
    A commercial generator helps prevent costly downtime, protects inventory and equipment, maintains employee productivity, and keeps critical systems operating during utility outages. It is an essential investment for businesses that rely on continuous power.
  • 7. What size commercial generator does my business need?
    Commercial generator sizing depends on your building's electrical demand, equipment requirements, and operational priorities. South Shore Generator performs a detailed site evaluation and load calculation to recommend the most efficient backup power solution for your facility.
  • 8. What fuel options are available for commercial generators?
    Commercial generators are commonly powered by diesel, natural gas, or propane. Each fuel type offers unique advantages depending on runtime requirements, fuel availability, environmental conditions, and local regulations. Our team will help determine the best option for your application.
  • 9. How often should commercial generators be tested and maintained?
    Commercial backup generators should be inspected regularly and professionally maintained at least annually, with many facilities scheduling quarterly service. Routine testing, load bank testing when appropriate, and preventative maintenance help ensure your generator performs reliably during an emergency.
  • 10. Does South Shore Generator provide installation and ongoing service?
    Yes. South Shore Generator provides complete turnkey solutions for residential and commercial backup power systems, including site evaluations, generator sizing, permitting, installation, startup, preventative maintenance, emergency repairs, remote monitoring, and scheduled service agreements.
