Greenlink installs permanent standby power systems that give your home an automatic, reliable backup the moment utility power fails.
Your home keeps life running. Your refrigerator, your sump pump, your home office, your medical equipment — none of it stops when you need it most. But the grid does.
No extension cords. No transfer switches you have to flip. No running out to get fuel. Just seamless protection — before you even know the power is out.
Why STANDBY POWER?
The grid wasn't built for this moment.
Severe weather events are more frequent. Utility infrastructure is aging. And the cost of being without power — even for a few hours — is higher than most homeowners realize.
What’s really at stake when the lights go out:
Medical equipment — CPAP machines, home oxygen systems, and refrigerated medications don’t wait for the utility company to restore service.
Sump pumps — The storm that knocks out your power is often the same storm flooding your basement.
Food and freezer inventory — A 48-hour outage can cost $500–$1,000 in lost food alone.
Remote work and home office — Deadlines don’t care about downed lines.
Farm and rural operations — Livestock systems, irrigation, well pumps, and cold storage can’t run on hope.
Home security and comfort — Climate control, lighting, and security systems all go dark without backup power.
A permanent standby system changes the equation. It’s not a contingency — it’s infrastructure.
OUR SOLUTIONS
Permanent Standby Generators
A standby generator is not a portable unit you roll out of the garage. It’s a professionally installed, permanently affixed system that monitors your utility connection around the clock.
The moment it detects a power loss, it starts automatically — typically within seconds — and runs your home on natural gas or propane until grid power returns.
What that means for your home:
- Whole-home coverage or critical-load protection (your choice, based on your needs and budget)
- No manual startup, no refueling in the rain, no extension cords
- Rated for continuous operation through extended outages
- Sized by our in-house engineers to match your actual load — not a one-size-fits-all guess
- Compliant with local codes and utility requirements, fully permitted and inspected
Standby generators are permanent additions to your property — installed on a concrete pad, connected to your fuel supply, and integrated directly into your home’s electrical panel.
Battery Storage Systems
Battery storage pairs cleanly with both solar and your existing home electrical system.
It stores energy during normal grid operation (or from your solar array) and releases it automatically during an outage — silently, instantly, without combustion.
Why homeowners are adding battery storage:
- Clean, quiet backup power — No exhaust, no noise, no fuel delivery to coordinate
- Solar self-reliance — Store the energy your panels produce during the day and use it at night or during grid events
- Peak shaving — In areas with time-of-use rates, battery systems can reduce what you pull from the grid during expensive peak hours
- Outage protection for critical loads — Even a single battery can keep your refrigerator, lights, router, and phone chargers running through most overnight outages
Our team evaluates your home’s load profile, your existing solar production (if any), and your backup priorities before recommending a system. The goal is right-sized protection — not oversold capacity.
Generator + Battery: The Strongest Combination
For homeowners who want complete, extended protection, standby generators and battery storage complement each other. The battery handles short-duration events and seamless transitions; the generator handles extended outages. Together, they cover every scenario.

We Don’t Just Sell Equipment. We Engineer Solutions.
Greenlink is a Midwest-based, veteran-owned energy solutions company with over a decade of experience designing and installing residential power systems. We’re not a big-box referral service. Our engineers, technicians, and incentives specialists are all in-house.

- In-house engineering — We design your system. Our team sizes the equipment, plans the installation, and pulls the permits.
- In-house incentives team — Available rebates, tax credits, and utility programs are built into your proposal automatically. Our incentives team saves the average customer $16,000. You shouldn’t have to figure that out on your own.
- Installation and ongoing service — The team that installs your system is the same team that services it. No subcontractors, no runaround.
- Manufacturer advisory relationships — We work closely with leading generator and battery manufacturers and sit on contractor advisory boards — so we know what we’re installing before it ever shows up at your door.
- Utility partnerships — We work directly with Peoples Gas and Nicor Gas on incentive and interconnection programs, which means fewer delays and smoother project completion.
Most of our residential resilience projects pay for themselves within a few years — especially when incentives are factored in.
