Questions to Ask Before Buying a Standby Generator
Choosing a standby generator is easier when you know which questions to ask before installation begins. The right generator depends on your property, power needs, fuel source, transfer switch, placement options, and long-term maintenance expectations.
This guide is designed to help Southeast Michigan homeowners, business owners, property managers, and facility teams understand what to consider before choosing a backup power solution.
Why Choosing the Right Generator Starts With the Right Questions
A standby generator is not a one-size-fits-all purchase. A home, business, or commercial property may have different backup power needs depending on what must stay running during an outage.
Before choosing a generator, it helps to understand what you want the system to support, how the generator will connect to the property, where it can safely be placed, and what maintenance will be needed after installation.
Before buying a standby generator, start with questions about:
- What needs backup power during an outage
- Whether you want whole-building backup or essential circuit backup
- Generator size and fuel type
- Transfer switch requirements
- Placement, clearance, and installation planning
- Permits or local requirements
- Maintenance after installation
Whole-Building Backup vs. Essential Circuit Backup
One of the first questions to ask is whether you want to power the entire property or only the most important systems. Some homeowners want broad backup power for comfort and convenience. Others only need essentials like heat, refrigeration, sump pumps, lighting, internet, or select outlets.
Businesses and facility teams may need to think differently. Backup power may be needed for equipment, security systems, refrigeration, lighting, access controls, communications, or operations that cannot be interrupted for long.
What size generator do I need?
Generator size depends on what you want to power during an outage. A qualified installer should review the property’s electrical needs, priority circuits, equipment, and load requirements before recommending a generator size.
Should I power the whole building or only essential circuits?
That depends on your comfort, budget, and operational needs. Essential circuit backup can support the most important systems, while whole-building backup may be more appropriate for properties that need broader coverage during outages.
Generator Size, Fuel Type, and Transfer Switch Basics
Standby generator planning should include more than the generator itself. The fuel source, transfer switch, electrical panel, and property layout all affect how the system is designed and installed.
What is the difference between a portable generator and a standby generator?
A portable generator is usually moved into place and manually connected for temporary use. A standby generator is permanently installed and designed to turn on automatically when paired with an automatic transfer switch.
What fuel type should I choose?
Common standby generator fuel options include natural gas, propane, and diesel. The right choice depends on the property, available utilities, generator type, runtime needs, and installation requirements.
What does an automatic transfer switch do?
An automatic transfer switch senses a power outage and transfers selected electrical loads from utility power to generator power. When utility power returns, the system transfers back safely.
Can a generator turn on automatically during an outage?
Yes, a properly installed standby generator with an automatic transfer switch can start automatically when utility power is interrupted. This is one of the main differences between a standby generator and many portable generator setups.
Placement, Permits, and Installation Planning
Generator placement should be reviewed before installation. Clearance, access, fuel connection, electrical routing, noise considerations, and local requirements can all affect where a generator can be installed.
Where can a standby generator be installed?
A standby generator needs a safe, accessible location with proper clearance, fuel access, and electrical routing. Placement should be reviewed before installation to help avoid problems with access, ventilation, or code requirements.
Do I need a permit for generator installation?
Permit requirements can vary by property type and local jurisdiction. A generator installer can help determine which electrical, mechanical, or local approvals may be needed before the work begins.
What should be included in a generator installation estimate?
A generator estimate should clearly explain the generator, transfer switch, installation scope, electrical work, fuel connection responsibilities, placement considerations, permits, and any work that may be handled by another trade.
What should I know before installation day?
Before installation, confirm the approved location, access to the work area, utility coordination, electrical panel details, and any preparation needed from the property owner or facility team.
Brand Considerations: Kohler, Generac, and Briggs & Stratton
Many property owners compare generator brands before making a decision. Brand choice is one part of the process, but it should not be the only consideration. The right fit also depends on sizing, installation quality, service access, maintenance needs, and the property’s backup power goals.
Should I choose Kohler, Generac, or Briggs & Stratton?
Each brand may offer different models, features, and service considerations. The best choice depends on the property, power needs, budget, fuel type, and long-term maintenance plan.
Can CRG service a generator they did not install?
If you already have a standby generator, CRG Electric can help review the equipment and determine the right next step for maintenance, service, or support.
What to Ask Before Hiring a Generator Installer
The quality of the installation matters as much as the generator selected. Before choosing a generator installer, ask how the property will be evaluated, what the estimate includes, how the transfer switch will be handled, and what maintenance support is available after installation.
Questions to ask before choosing a generator installer:
- Will the installer evaluate my actual electrical needs before recommending a generator?
- Will the estimate explain the generator, transfer switch, electrical work, and installation scope?
- Who handles permits or local requirements?
- How will generator placement be determined?
- What maintenance is recommended after installation?
- Can the installer help with future generator service or testing?
