Generac is best known for backup power, from standby units wired into a house to portable generators you wheel out during a storm. If you searched for a Generac solar generator, here is the honest picture from these listings: three of the four products below are fuel-burning generators that run on gasoline, propane or natural gas, and the fourth is a 100 watt solar panel. The solar panel does not power or charge those generators. Its listing says it is made to recharge a Generac portable power station, which is a battery unit sold separately and not part of this roundup.
So the real choice is between three sizes of fuel generator, from a light 3,300 watt inverter to a 12,500 watt tri-fuel unit, plus a solar panel that only makes sense if you pair it with a compatible Generac battery station.

Generac 5,200 Watt Dual-Fuel Portable Inverter
Best for: RV owners and flexible home backup
Pros
- Gas or propane
- Clean power under 3% THD
- 30A RV outlet
- Electric start, COsense
Cons
- 107 lbs to move
- Small 0.6 gallon tank listed
The Generac 5,200 Watt Dual-Fuel Portable Inverter generator, which the description calls the iQ5200 DF (Model 8945), runs on either gasoline or liquid propane. On gas it gives 3,900 running watts and 5,200 starting watts; on propane it gives 3,500 and 4,700. Starting watts are the short burst of extra power a fridge or air conditioner needs to kick on, while running watts are what it can supply continuously. The description says it can start and run a 13,500 BTU RV air conditioner, a refrigerator, power tools and multiple devices at once.
“Inverter” means it produces clean power, listed as less than 3% THD (total harmonic distortion), which the listing says is safe for laptops, tablets and phones. Economy Mode reduces fuel use and noise. The listing gives runtimes of up to 9 hours on gas or 11 hours on a 20 lb propane tank at 50% load, and up to 15 hours on gas at 25% load. It has push-button electric start with an included battery, and COsense, which shuts the unit down if dangerous carbon monoxide levels are detected. Outputs include a 120V 30A RV-style outlet, two 120V 20A GFCI outlets, USB-A and USB-C ports, and an LED display. Two units can be linked with an optional parallel kit for up to 7,800 running watts.
Two listing details look inconsistent: the spec sheet says 2 total power outlets and a 0.6 gallon tank, while the features describe more outlets and long runtimes. Trust the detailed feature list and confirm tank size in the manual. At 107 lbs with never-flat wheels, this Generac 5200 watt dual fuel model suits RV owners and households who want propane as a backup fuel.

Generac 100 Watt Solar Panel
Best for: Recharging a Generac power station outdoors
Pros
- 100W tri-fold panel
- Waterproof and dustproof
- Two kickstands, zip pouch
- Parallel up to four panels
Cons
- Cannot charge fuel generators
- Power station sold separately
The Generac 100 Watt Solar Panel, model GS100, is a folding solar panel rather than a generator. The description says it is designed to recharge a Generac power station on the go, away from wall outlets or car chargers. A power station is a large rechargeable battery with outlets on it, and that is the device doing the powering; the panel just refills it with sunlight.
It has a lightweight tri-fold design, two built-in kickstands to angle it at the sun, and a zippered pouch for cords. The listing calls it waterproof, dustproof and chemical resistant, gives a maximum power of 100 watts, an efficiency figure of 0.22 (22%), an XT90 connector and a weight of 9.7 pounds. You can connect up to four GS100 panels together for up to 400W of combined charging, and a parallel cable is included.
This Generac solar panel 100 watt model suits someone who already owns, or plans to buy, a compatible Generac power station. It will not charge any of the three fuel generators in this list. If you want a battery station and panel sold as a set, our guide to a solar generator with a matching panel shows how those bundles work.

Generac 12,500 Starting Watt Tri-Fuel Portable
Best for: Whole-home backup and job sites
Pros
- Gas, propane or natural gas
- 9,500 running watts
- 240V 30A and 50A outlets
- Transfer switch compatible
Cons
- Heavy at 219 lbs
- Not an inverter model
The Generac 12,500 Starting Watt Tri-Fuel Portable generator, described as the GP9500E Tri-Fuel (Model 8063), is the heavyweight of the group. It runs on gasoline, liquid propane or natural gas, selected with a dial, and delivers 9,500 running watts and 12,500 starting watts on gas from a 500cc Generac OHV engine. The listing says it can handle refrigerators, sump pumps, window air conditioners and electric furnace blowers.
It uses automatic voltage regulation (AVR) to keep output steady for motor-driven tools and appliances; the listing does not describe it as an inverter. The 7.5-gallon tank gives up to 9.5 hours at 50% load or 14 hours at 25% load on gas, and a natural gas line allows much longer runtime. Outlets include two 120V 20A GFCI duplex outlets, a 120/240V 30A twist-lock and a 120/240V 50A outlet, plus an hour meter. COsense, electric start and low oil shutdown are listed, and it is compatible with Generac manual transfer switches for safe home connection.
At 219 lbs on 9.5-inch never-flat wheels, this Generac tri-fuel generator is for homeowners who want to run major appliances during long outages, and for contractors. It is too big and heavy for most camping trips. For a permanent setup that starts on its own, see our Generac home generator guide.

Generac 3,300 Watt Gas Powered Portable
Best for: Campers and light outage backup
Pros
- Light at 59.5 lbs
- Clean power, CPAP safe
- Economy Mode
- USDA spark arrestor
Cons
- Gasoline only
- Up to 7 hours at 25% load
The Generac 3,300 Watt Gas Powered Portable Inverter Generator, called the GP3300i in its features, is the lightest option at 59.5 pounds with a molded carry handle. It produces 2,500 running watts and 3,300 starting watts, which the listing says can run a refrigerator, lights, a TV and phone charging at the same time. PowerRush technology is credited with giving it 50% more starting capacity.
TruePower technology produces a stable sine wave with less than 3% THD, and the listing names laptops, tablets and CPAP machines as safe loads. Economy Mode adjusts engine speed to save fuel and cut noise, and COsense shuts it off if CO builds up. The 1.06-gallon tank runs up to 7 hours at 25% load or 4.5 hours at 50% load. Outlets include two 120V 20A household outlets, one 120V 30A twist-lock and two USB-A ports, and a second unit can be linked with a sold-separately parallel kit. It includes a USDA-qualified spark arrestor for use in national forests and parks.
This Generac 3300 watt inverter is the pick for campers, tailgaters and small households who need to keep a fridge and a few lights going. It runs on gasoline only, so step up to the 5,200 watt model if you want propane as an option.
How to Choose the Right Generac Generator
Solar generator vs gas generator. A “solar generator” usually means a battery power station charged by solar panels: silent, fume-free and safe indoors, but limited by battery size. A gas generator burns fuel, makes far more power for longer, but must run outdoors away from windows. The Generac products here are gas generators, plus one panel for a separate battery station. For a battery-and-panel approach, our look at a portable power station explains the basics.
Add up your watts. List what you want to run and add the running watts, then allow for the largest starting surge. A fridge, lights and phones fit the 3,300 watt model; an RV air conditioner points to the 5,200; furnace blowers and a sump pump together point to the 12,500 tri-fuel.
Choose a fuel. Gas only is simplest. Dual fuel adds propane, which stores well. Tri-fuel adds natural gas for long outages.
Think about weight. 59.5 lbs can be carried; 107 lbs and 219 lbs need wheels and flat ground.
FAQ
Does Generac make a solar generator?
Among these four listings, no product is a solar generator on its own. The GS100 panel recharges a Generac power station, which is sold separately.
Can the Generac 100W solar panel charge a gas generator?
No. Its listing describes it only as a charger for a Generac power station.
Which Generac generator should I buy for camping?
The 3,300 watt GP3300i is the lightest and includes a spark arrestor for parks. The 5,200 watt dual fuel model also includes one if you need more power.
Which Generac portable inverter generator is safe for electronics?
Both the 5,200 watt and 3,300 watt models list less than 3% THD, meaning clean power for sensitive devices.
Can I run a generator indoors or in a garage?
No. Fuel generators produce carbon monoxide. COsense is a safety backup, not permission to run one indoors.
