Our take on the WEN 8750-Watt RV and Transfer-Switch-Ready 120V/240V Electric Start Open Frame Inverter Generator

The WEN 8750 is a gas open-frame inverter generator rated at 7000 running watts and 8750 surge watts, with both 120V and 240V output. It uses inverter technology for cleaner power than a conventional open-frame unit, and it starts with a key instead of a pull cord. A 4.2-gallon tank runs about 6.7 hours at half load, and WEN says it weighs roughly 30 percent less than a traditional 8750-watt generator. It suits RV owners and home backup users who want 240V and a transfer-switch hookup without a heavy conventional frame unit; it is louder and heavier than a closed-frame inverter, and it is not a quiet campsite generator.

Questions and answers

Can it power an RV air conditioner?
Yes. The 8750 surge watts and TT-30R outlet handle a 30-amp RV, including a single air conditioner startup, though running two large loads at once may trip the overload protection.
Does it produce clean power for electronics?
Yes. Inverter technology gives steady sine-wave output suitable for laptops, TVs and phones, unlike a conventional open-frame generator.
How loud is it?
WEN rates it at 65 dB. That is quiet for an open-frame unit but louder than a closed-frame inverter, so it is not ideal for crowded campgrounds.
Can I connect it to a home transfer switch?
Yes. The 120V/240V output and transfer-switch-ready design let you feed a manual transfer switch, but a qualified electrician should handle the hookup.
What safety shutoffs does it have?
It has a WEN Watchdog CO shutdown sensor, low-oil shutdown and overload protection, all of which cut the engine or output before damage.
How long does it run on a tank?
About 6.7 hours at half load on the 4.2-gallon tank. Eco-mode stretches runtime at lighter loads.
