The short verdict on solar generator vs tri fuel generator use: pick the solar example for a panel-included kit that recharges from sun, wall socket or car outlet, and pick a tri fuel example for large starting watts on gasoline, propane or natural gas. The DuroMax and WEN examples state larger watts than the MARBERO example, while the MARBERO example states a panel, a small station size and a small weight that the tri fuel examples do not state. This article compares the listings on what each listing states, without calling a whole side better on a figure only one example states.

Power and outlets
Power is where the examples sit furthest apart, and every figure below belongs to the example named. The DuroMax example states 15,000 starting watts and 12,000 running watts. The WEN example states gasoline surge watts of 14,500 and running watts of 11,500, propane surge watts of 12,500 and running watts of 10,300, and natural gas surge watts of 10,500 and running watts of 8,750. The MARBERO example states 200W AC output with 270W surge, and 8 output ports in its title, including AC, USB A, USB C and DC ports. The DuroMax example states GFCI 120V household outlets and 30A and 50A transfer-switch-ready receptacles. The WEN example states 120V 5-20R outlets, a 120V/240V NEMA L14-30R outlet, a 120V/240V NEMA 14-50R outlet and a 12V DC automotive outlet. See our gas generator vs inverter generator guide for another fuel comparison.
Fuel and recharging
The fuel picture is clear for the tri fuel examples and different in kind for the solar example. The DuroMax example states tri-fuel operation on gasoline, propane, or natural gas, without giving a separate watt figure for each fuel. The WEN example states the same three fuels, with a dial to switch fuels, and it gives a separate surge and running watt figure for each fuel. The MARBERO example states recharging by AC 110V wall socket in 7 to 8 hours, by solar panel, and by car lighter outlet, with a 40W foldable panel included. The WEN example states up to 12 hours of half-load runtime with an 8.2-gallon tank. The DuroMax example states no runtime figure, and the MARBERO example states a recharge time rather than a load runtime, so that comparison stays unclear for those two examples.
Size and weight
Size and weight follow the power gap, with one gap in the listings. The DuroMax example states a size of 29.5 by 28.0 by 26.0 inches and a weight of 245.0 pounds. The WEN example states a size of 28.8 by 28.3 by 25.8 inches, and it states no weight figure, so the WEN example leaves weight unclear. The MARBERO example states a station size of 7.6 by 3.6 by 5.4 inches and a station weight of 3.3 pounds, plus a panel weight of 2.3 pounds, with a panel size of 8 by 10 by 1 inches folded and 32 by 10 by 0.8 inches unfolded. The MARBERO example states a panel size and weight; the DuroMax and WEN examples state no panel.
Safety and shutdown
Safety features differ by example. The WEN example states a CO Watchdog shutdown sensor that turns the generator off if dangerous levels of carbon monoxide are detected. The DuroMax example states GFCI 120V household outlets, and it states no CO shutdown sensor. The MARBERO example states a smart chip against overcharging and overloading, with a panel conversion rate of 21.5 to 23.5 percent. Fuel generators run outdoors only, far from doors and windows, because of carbon monoxide. A licensed electrician should install any transfer-switch connection. No wiring steps are given here.
What the listings leave unclear
Several points stay unclear even after reading all three listings. No listing states a noise level, so a noise comparison cannot be made from these listings. The DuroMax example states no runtime figure and no CO shutdown sensor. The WEN example states no weight figure. The MARBERO example states no load runtime figure and no transfer-switch-ready receptacle. The MARBERO panel conversion figure is stated as a range of 21.5 to 23.5 percent, not as a single figure. Those gaps make the affected comparisons unclear, not wins for either side.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For a generator comparison, safety means a stated CO shutdown sensor, GFCI outlets, or a stated protection chip, and each example here states a different safety detail. Two examples state a warranty term, the DuroMax example at 5 years and the MARBERO example at 12 months, while the WEN example states no warranty term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| DuroMax XP15000HXT+ | 9.7 | 32 | 21 | 20 | 7 | 3 |
| WEN TF-1450X | 9.6 | 30 | 21 | 21 | 8 | 0 |
| MARBERO M822MAX | 9.5 | 28 | 20 | 20 | 5 | 2 |
We place weighted points on a scale whose ends are 9.2 and 9.8. Because the mapping is straight, a unit with more points never shows less.
Solar generator vs tri fuel generator: which should you choose?
Choose the MARBERO example if the job is a small, panel-included kit for camping, fishing and home emergency use, with recharging from sun, wall socket or car outlet. Choose the DuroMax example if the job needs 15,000 starting watts with transfer-switch-ready receptacles stated. Choose the WEN example if the job needs a CO shutdown sensor stated, electric start, and a stated half-load runtime of up to 12 hours. Do not choose a side on a figure only one example states, such as a panel size or a CO sensor, without checking that the example you buy states that figure.
| If you need | Look at |
|---|---|
| A small panel-included kit | MARBERO M822MAX, 172Wh, 40W panel included |
| Large starting watts stated | DuroMax XP15000HXT+, 15,000 starting watts |
| A CO shutdown sensor stated | WEN TF-1450X, CO Watchdog shutdown sensor |
| A stated half-load runtime | WEN TF-1450X, up to 12 hours of half-load runtime |
Sizing Notes
- Match the stated watts, using 15,000 starting watts and 12,000 running watts for DuroMax, the per-fuel watts for WEN, and 200W AC with 270W surge for MARBERO.
- Match the fuel or recharge source, using gasoline, propane, or natural gas for DuroMax and WEN, and solar panel, AC wall socket or car lighter outlet for MARBERO.
- Match the size to the space, using 29.5 by 28.0 by 26.0 inches for DuroMax, 28.8 by 28.3 by 25.8 inches for WEN, and 7.6 by 3.6 by 5.4 inches for the MARBERO station.
- Match the outlets, using the GFCI and transfer-switch-ready receptacles for DuroMax, the outlet types for WEN, and the 8 output ports for MARBERO.
FAQ: power away from the grid
Which example states the largest starting watts?
The DuroMax example states 15,000 starting watts. The WEN example states gasoline surge watts of 14,500, and the MARBERO example states 270W surge.
Can the MARBERO example run on gasoline?
No fuel is stated for the MARBERO example. Its listing states recharging by solar panel, AC 110V wall socket, and car lighter outlet, with a 40W foldable panel included.
Do both tri fuel examples state the same fuels?
Yes, both state gasoline, propane, and natural gas. WEN gives a separate figure for each fuel; DuroMax states 15,000 starting watts and 12,000 running watts without a per-fuel split.
Which example states a CO shutdown sensor?
Only the WEN example states a CO Watchdog shutdown sensor. The DuroMax example states GFCI outlets and no CO shutdown sensor, and the MARBERO example states a smart chip against overcharging and overloading.
Which example states a load runtime?
Only WEN states a load runtime, at up to 12 hours of half-load runtime with an 8.2-gallon tank. DuroMax states no runtime figure, and MARBERO states a recharge time of 7 to 8 hours by AC wall socket rather than a load runtime.
