Quick answer

Generac, by 02 Energy installs home standby generators across all 21 New Jersey counties. Your project starts with a sales engineer call, a preliminary soft quote when the home can be verified, and an onsite assessment before the final written quote. From there, we handle sizing, permits, engineering needs, transfer switch selection, installation, inspections, commissioning and Mobile Link setup.

Current Model

We install Generac's Next Generation standby generators.

Not every generator quote is for the same equipment. Generac's current Next Generation standby line includes built-in cellular connectivity, Mobile Link control, remote diagnostics, oil-level sensing, improved cold-start performance, and a sloped roof with rear air intake to reduce snow and ice intrusion.

When you compare proposals, ask whether the quote is for the current Next Generation model or older Guardian-series equipment. The model matters because the transfer switch, controls, connectivity and service path all affect the final system you live with after installation.

Standby power beats a portable generator every time the grid goes down

A portable generator means waking up in a storm, running an extension cord out a window, and standing outside refueling it every few hours - if you are home to do it at all. A standby generator is wired directly into your electrical panel and sits ready year-round. It starts on its own, whether you are asleep, at work, or away for the weekend, and it keeps running as long as it has fuel.

That difference matters most exactly when you cannot be there to manage it - which is the whole point of backup power in the first place.

Compare Quotes

What a serious generator proposal should make clear

A lower number is not always a better project. A standby generator ties into your electrical service, transfer switch, fuel supply, permits and life-safety systems, so the quote should explain the whole system.

Sales engineer review

Your first call is a technical project review, not just a price check. We ask about the home, panel, fuel source, special loads, timing and location so the onsite visit starts with context.

Generac-first expertise

Generator work is handled by a licensed electrical contractor that sells, installs, starts up and supports Generac systems instead of treating the generator as an add-on.

Transfer switch fit

If you already have an ATS, it still has to match the service size, protected loads and current generator controls. A small reuse savings is not worth building around the wrong switch.

Electrical and fuel safety

The quote should account for panel work, gas or propane capacity, clearances, load management, permits and inspection steps. This is not a plug-in appliance.

Warranty terms in writing

Warranty terms and what is included should be documented clearly, including the seven-year all-in Generac warranty and five-year standard workmanship coverage.

Financing expectations

A standby generator is a serious home system, so payment options should be discussed early. We can quote Synchrony financing alongside the written cash price for qualified buyers.

What is included in every installation

Generator work is not just placing equipment outside. It touches your electrical service, fuel supply, local code requirements and municipal inspection schedule. Our job is to make that feel organized from the first sales engineer call.

Sales engineer review

We start with a practical technical review, then confirm the final scope onsite so the written quote reflects the actual home.

Permits and inspections

Township permits, inspection scheduling and project paperwork are handled by Generac, by 02 Energy instead of being pushed onto the homeowner.

Gas and electrical installation

The transfer switch, generator pad, electrical connections and fuel work are coordinated around code and manufacturer requirements.

Engineering when needed

Some homes need additional review for placement, structure, service equipment or unusual site conditions. We identify that before the project moves too far.

Commissioning and Mobile Link

After installation, the system is started, tested and connected to Generac Mobile Link so you can monitor status and alerts from your phone.

Warranty and maintenance path

The generator includes a seven-year all-in Generac warranty, and standard installation workmanship is covered for five years.

Why Generac

What a Generac standby unit actually does for your home

Whole-home coverage

Sized correctly, a Generac unit carries HVAC, kitchen appliances, well pumps and everyday electronics together, not just a handful of circuits on an extension cord.

Auto-start in seconds

The transfer switch detects an outage and starts the unit automatically, with power restored to your home typically within seconds - no one has to be home to make it work.

Natural gas or propane

Runs on whichever fuel supply your home already has or can support, so there is no gasoline to store and no tank to refill under stress mid-storm.

Quiet weekly self-test

The unit runs a short self-check on its own schedule to confirm it will start when it is needed, then shuts back off - a brief sound, not a daily disruption.

Mobile Link monitoring

Generac's app-based monitoring tells you the unit's status, maintenance alerts and outage history from your phone, whether you are upstairs or out of state.

Warranty registered at startup

Every unit we install is registered with Generac at startup, and the seven-year all-in warranty is documented with your project.

Sizing a generator to your home

Exact sizing depends on your panel, square footage and what you want to keep running. We confirm the right unit at the free assessment, then put the price and financing options in writing.

Essentials

10 to 14 kW

Covers refrigeration, sump pump, well pump, lights and Wi-Fi. A solid entry point for homes focused on the critical loads.

Whole home

18 to 26 kW

Covers HVAC alongside the essentials - most NJ homes land in this range when the goal is not noticing the outage at all.

Large estate

26 kW and up

Larger homes, multiple HVAC zones, pools or well-heavy properties. Sized with a full load calculation, not a guess.

Sizing is not a guess based on square footage alone. We walk the panel, confirm the circuits you want protected, and explain why the recommended unit fits your home before anything goes into the final written quote.

Project Timeline

A real process, not a mystery install date

The equipment may only take a few working days to physically install, but a proper standby generator project also moves through design, permit, inspection and startup steps which can take several weeks to complete. Our team works diligently throughout this process to ensure all projects are installed as quickly and properly as possible.

Step 1

Quote and onsite confirmation

We review the home, prepare a preliminary number when possible, then confirm the final scope onsite before the written quote.

Step 2

Permits and approvals

Generac, by 02 Energy handles the township filing, regulatory documentation and approval tracking so the project is ready for installation.

Step 3

Electrical and gas installation

The generator, transfer switch and fuel connection are installed through coordinated crew visits once approvals are in place.

Step 4

Inspection and commissioning

After required checks, a technician starts the unit, tests the transfer switch, sets up Mobile Link and walks you through what to expect.

Many projects are substantially completed in about 45 to 60 days, with final inspection timing depending on the municipality. The important distinction is that final municipal closeout can take longer than the physical install, and we manage that process for you.

Timing Matters

Order before storm season, not during it

New Jersey's storm season regularly brings multi-day outages from nor'easters and hurricane remnants, and that is exactly when generator demand and installation backlogs spike.

Order in spring or early summer

Homeowners who start the process before the season gets busy are the ones with power when the fall storms actually hit.

Order right before a storm

Expect longer waits for equipment, a backed-up permit queue, and a real chance the unit is not installed until after the outage that prompted the call.

Plain English

Generator terms you should understand before buying

These are the terms that matter when you compare quotes. If a proposal skips them, you may not be comparing the same project.

Automatic transfer switch

The ATS watches utility power, starts the generator during an outage, and safely transfers selected home circuits to generator power.

Load management

Large loads like an EV charger, pool equipment, hot tub or HVAC can be managed so the generator protects the home without overloading.

Commissioning

This is the startup and test process after installation. The unit runs, the switch is checked, and the system is confirmed ready.

Mobile Link

Generac Mobile Link lets you monitor generator status, maintenance alerts and outage history from your phone or computer.

Generator Installation FAQs

How does a standby generator start itself during an outage?

An automatic transfer switch monitors utility power around the clock. When it senses an outage, it signals the generator to start, and once the generator is up to speed the switch moves your home's load over to it - typically within seconds, with no one home and nothing for you to do.

Natural gas or propane - which should I choose?

If your home already has a natural gas line, that is usually the simplest and most convenient fuel source - unlimited runtime, no tank to monitor. Without gas service, a propane tank is the standard alternative. We review what is available at your address during the free assessment and size the fuel supply to the unit.

What happens after I request a generator quote?

A Generac, by 02 Energy sales engineer calls to understand the home, fuel source, panel, generator goals and preferred location. When the project looks straightforward, we can give a preliminary soft quote based on what we can verify remotely. The final written quote comes after the onsite assessment confirms the panel, fuel supply, generator location, clearances, load needs and permit requirements.

Why do you ask about gas, panels, pools, hot tubs, EV chargers or solar?

Those details affect generator sizing, transfer switch selection, load management and code requirements. Load management is how larger electrical loads are controlled so the generator does not get overloaded. A hot tub, pool, EV charger or solar system does not automatically stop a project, but it does need to be accounted for correctly.

Where does the generator sit, and how loud is it?

Units are installed outside on a pad, set back from windows and property lines per township code. Modern Generac units run at roughly the volume of normal conversation, and they run a short self-test weekly - you will hear it briefly, then it shuts back off.

Is it true I should order before storm season?

Yes, and it is worth planning around. Between manufacturer lead time and a permit and inspection process that commonly runs around six weeks in NJ townships, a generator ordered in the middle of hurricane season often is not installed until the season is over. Homeowners who order in spring are the ones with power when the fall storms hit.

What maintenance and warranty should I expect?

Standby generators need an annual service visit for oil, filters, battery and a full system check, similar to servicing a car. The generator includes a seven-year all-in Generac warranty, and standard installation workmanship is covered for five years. We register the Generac warranty at startup and confirm the installation warranty terms in writing with your quote.

Can you reuse an existing automatic transfer switch?

Sometimes, but it is not automatic. The transfer switch must match the home service, the protected loads and the generator controls. If the switch is older, undersized or incompatible with a current Generac unit, replacing it is usually the safer long-term decision. We check that before final pricing.

Do I have to handle permits, inspections or startup myself?

No. Generac, by 02 Energy handles permit filing, inspection coordination and required township paperwork as part of the project. After the equipment is installed and required checks are complete, a technician commissions the generator, tests the system, confirms the transfer switch, and sets up Mobile Link with you.

Can I monitor the generator from my phone?

Yes. Generac Mobile Link lets you monitor generator status, maintenance alerts and outage history from a phone, tablet or computer. During commissioning, our technician helps set up the app so you know how to check the system.

How much does a standby generator cost installed?

Total cost depends on the unit size, fuel source, and what the pad and gas or electrical work require at your specific home - there is no single number that applies to every property. We give you an exact written price at the free assessment, and $0 down financing is available through Synchrony for qualified buyers, with monthly payment options quoted alongside the cash price.

How long does a generator installation take from start to finish?

The physical installation is usually only a few working days once approvals are ready. The longer part is the township permitting, utility coordination and inspection cycle, which varies by municipality. Many projects are substantially completed in about 45 to 60 days, with final inspection timing depending on the town.
