Description

The FIRMAN WH03042 Dual Fuel Inverter Generator delivers quiet, fuel-efficient power with the flexibility to run on gasoline or propane. Designed for RV trips, camping, tailgating, and home backup, this portable inverter generator provides clean power with less than 3% THD—safe for laptops, smartphones, TVs, and other sensitive electronics.

Powered by a reliable 171cc FIRMAN engine, the WH03042 produces 3,300 starting watts and 3,000 running watts on gasoline, and 3,000 starting watts and 2,700 running watts on propane. The electric start with recoil backup ensures easy operation, while Eco Mode automatically adjusts engine speed to maximize fuel efficiency and extend runtime. A 1.8-gallon fuel tank delivers up to 9 hours of runtime at 25% load.

The multi-feature control panel offers versatile outlet options to power multiple devices at once, including (1) 5-20R 120V 20A duplex outlet, (1) TT-30R 120V 30A RV-ready twist-lock outlet (25A/120V/3000W), (1) USB-A port (2.1A/5V DC/10W), and (1) 12V DC power port (8.3A/12V DC/100W). Low oil shutoff protection adds durability and peace of mind.

Lightweight, portable, and operating at just 58 dB at 25% load, the WH03042 is built for quiet performance wherever you need dependable power.

Why Buy From Project Foundry?

Pro-grade equipment, real support, and a buying experience built around big-ticket gear. Here's exactly what you get with every order.

Project Foundry
Hassle-Free Freight Delivery

Most equipment ships by freight on a pallet. Here's what to expect: orders process in 1 to 2 business days, with typical transit of 4 to 7 business days. The carrier calls ahead to schedule a curbside delivery appointment, so keep a good phone number on your order. Liftgate service is included on many items. Large equipment like car lifts and attachments are too big for a liftgate and need a forklift or similar to unload. No equipment on site? You've got options: have it delivered somewhere that does, like a neighbor's place or your workplace, or have it sent to a local freight terminal such as Estes or Old Dominion, where you can pick it up with a trailer and their forklift loads it for you. Contact us to arrange terminal pickup. Inspect before you sign: note any damage on the delivery receipt before signing, and for concealed damage, send us photos within 48 hours to protect your replacement coverage. Questions about delivery to your address? Call or text 331-272-5655. Full details are on our Shipping Policy.

Lowest Prices Online

We keep every price at the lowest point the manufacturer allows, so you're always starting from the best price we're permitted to advertise. Want to do better than that? We offer additional discounts for new customers, holidays, veterans, healthcare workers, and more. Call 331-272-5655 for exclusive pricing. Paying by wire, ACH, or check? Take an extra 3% off, since we skip the credit card processing fee and pass that savings straight to you.

Found it cheaper from another authorized dealer? Tell us. We'll verify they're a legitimate dealer and do our best to match or beat the price. We don't match eBay or marketplace listings. Reach us at 331-272-5655 before you order. Full terms are on our Price Match Guarantee page.

Free Warehouse Pickup

Many items are available for free pickup at our supplier warehouses, so you can skip freight charges entirely. Availability depends on the product and brand. Once your order is ready, we'll send written authorization with the location and pickup instructions, so please wait for that confirmation before heading out. Plan to pick up within 48 to 72 hours of the ready notice. Want to know if your item qualifies? Call or text 331-272-5655.

Authorized Dealer, Full Factory Warranty

We're an authorized dealer for every brand we carry. That means factory-fresh equipment with the full manufacturer warranty, never gray-market product from a random marketplace seller. If you ever need a warranty claim, we help you through it.

Heads up: the equipment world has its share of fake websites and unauthorized sellers pushing prices that are too good to be true. If you're ever unsure about a seller, reach out. We'll help you spot the red flags, even if you don't end up buying from us.

Flexible Monthly Financing

Spread the cost out with Shop Pay Installments. Break a big purchase into manageable monthly payments and get your equipment now instead of saving up for it. Select Shop Pay at checkout to see your options.
