A whole-home standby generator is permanently installed outside your home or business and turns on automatically within seconds of a power outage — no manual setup, extension cords, or trips to the gas station. A portable generator has to be manually started, fueled, and connected each time, and typically only powers a few select items at a time. For homeowners and businesses that want reliable, hands-off backup power, a standby generator is the far more practical solution.

A battery backup system stores energy — often charged by your solar panels — and discharges it silently and instantly during an outage, with no fuel required. A standby generator produces power on demand by burning fuel and can run for as long as fuel is supplied, making it well-suited for extended outages. Each has strengths: batteries offer quiet, seamless, fuel-free backup, while generators offer extended runtime regardless of weather or sunlight. Many of our customers use both together for the most complete protection.

It depends on how long you need backup power to last and what you want it to cover. Battery backup is excellent for shorter outages and daily resilience, especially when paired with solar to recharge itself. A generator is built for longer outages, since it can keep running as long as fuel is available. If your goal is comprehensive protection — especially through Florida's hurricane season — pairing both gives you the best of each. We'll help you evaluate your specific needs, budget, and goals to determine what's right for you.

Yes — in fact, this is one of the most effective setups we design. Your battery backup can handle the immediate, seamless transition when the power goes out and cover shorter outages quietly, while your standby generator kicks in for extended outages, refueling and recharging your battery system along the way. This layered approach gives you the fastest response, the quietest operation, and the longest runtime, all in one plan.

Both have a role to play, and the right answer depends on what you're protecting against. Battery backup (especially paired with solar) gives you silent, immediate power without needing fuel — valuable when fuel becomes hard to find in the days around a storm. A standby generator gives you extended runtime for outages that last many days, which is common after major hurricanes. Many of our customers choose to pair solar, battery backup, and a Generac generator together for a complete resilience plan that covers both the first hours and the following weeks of an outage.

Your standby generator is connected to an automatic transfer switch, which continuously monitors your utility power. The moment it detects an outage, it signals the generator to start and automatically shifts your home or business over to generator power — typically within seconds, without you having to do anything.

It depends on how the system is sized and designed. Some homeowners choose a generator sized to run their entire home as normal, while others opt for a system that covers essential circuits — things like refrigeration, well pumps, HVAC, and medical equipment. For businesses, this same choice applies to critical operations versus full building power. We'll walk through your priorities and size a system that matches what you actually want covered.

Generac standby generators typically run on natural gas or liquid propane, connected to an existing fuel line or a dedicated propane tank. Unlike a portable generator, you don't need to manually refuel it frequently — as long as fuel supply continues, the system runs automatically for as long as it's needed.

Sizing depends on what you want the generator to power — your entire property or just essential systems — along with your square footage, major appliances, and equipment. We assess your property's electrical load and walk through your priorities to recommend a Generac model sized correctly for your needs, rather than guessing or over- or under-sizing the system.

Yes, standby generator installation typically requires electrical and plumbing permits, and depending on your fuel source, may involve additional inspections. Transform Solar handles the permitting process for you as part of the installation, residential or commercial.

Most residential installations are completed within a day or two once your system is designed and permitted, though the full process — including permitting and any required utility or gas line coordination — takes longer than the physical install itself. Commercial installations vary more based on system size and site requirements. We'll give you a project-specific timeline as part of your quote.

Both are possible, depending on how the system is designed. Some businesses need full operational continuity — point-of-sale systems, refrigeration, HVAC, lighting, everything — especially if downtime means lost revenue or spoiled inventory. Others only need critical systems covered to protect equipment, security, or safety-critical operations. We'll help you determine the right scope based on what an outage actually costs your business.

Commercial generator sizing depends heavily on your facility's total electrical load, critical equipment, and whether you're aiming for full building coverage or essential-systems-only backup. Because commercial needs vary so widely — from a small office to a facility with heavy equipment or refrigeration — we conduct a detailed load assessment for every commercial project rather than relying on general estimates.

Generac generators are built for long-term reliability but do require periodic maintenance — things like oil changes, filter replacement, and battery checks — similar to a vehicle. Routine maintenance keeps your system ready to perform when you actually need it during an outage.

We're with you after installation, not just during it. Our team can provide ongoing service and maintenance to keep your Generac system running reliably, so you're not left to figure out upkeep on your own or search for a separate service provider.

Cost depends on the generator size, fuel type, installation complexity, and whether it's paired with solar or battery backup. Whole-home and essential-circuit systems land at different price points, and commercial systems vary further based on facility size and load requirements. We'll provide an exact quote based on your property and goals.

Yes — Transform Solar offers financing options for generator installation, including as part of a combined solar, battery backup, and generator package. We can walk you through what's available so you can choose the approach that fits your budget.
