Backup loads under 5,500 running watts on propane with 240V needs

A 322cc dual fuel inverter rated 6,100 running watts on gasoline and 5,500 on propane, with L5-30R and L14-30R receptacles, a 120/240V switch, electric start with a pre-installed battery and a CO shutoff. It weighs 130 pounds. Fuel Sense uses propane first whenever the cylinder valve is open, and the parallel kit is a separate purchase.

Fit and limits

Strengths

  • L14-30R 120/240V and L5-30R receptacles plus a 5-20R duplex
  • Separate gas and propane ratings, with automatic propane-first fuel switching
  • Battery, float charger, oil and propane hose included per the manual

Caveats

  • Maker documents disagree on parallel cables and mention outlets not on the panel
  • 130 pounds, so moving it relies on the handle and wheels
  • Parts-only coverage in warranty years two and three

A 322cc dual fuel inverter sold as model SUA7600iED

Amazon's model field for this listing reads 3222004, and the maker's owner's manual cover pairs that same number with SUA7600iED. A-iPower's product page and spec sheet carry the same UPC as the listing, so all four describe one unit. It is a 322cc, single-cylinder, four-stroke inverter generator that runs on gasoline from a 3.6-gallon tank or on propane from a separate cylinder.

The manual's parts list names a 700 ml bottle of oil, a spark plug wrench, a screwdriver, a 30 amp RV adapter, a screw-on funnel, a propane hose with regulator, a battery float charger and a 12V DC battery charging cable, plus the manual and quick start guide. Amazon and the spec sheet both give 130 pounds. The maker's noise claim is as low as 62 dBA, with no distance or load stated, and its THD figure is under 3 percent.

Use the running watts for the fuel you will actually burn

A-iPower rates the SUA7600iED at 7,600 starting and 6,100 running watts on gasoline, and 6,900 starting and 5,500 running watts on propane. There is no natural gas rating. The 7,600 in the listing title is the gasoline starting figure. If you plan to run on propane during an outage, size your loads against 5,500 running watts, not the headline number.

The manual also says output drops about 3.5 percent for each 1,000 feet of altitude and about 1 percent for each 10°F above 60°F, and that the unit is rated for continuous operation up to 104°F. The maker's runtime claim is up to 10 hours at 25 percent load on gasoline. No document we read gives a propane runtime or a runtime at heavier loads.

Fuel Sense picks propane first whenever the cylinder valve is open

The manual describes Fuel Sense as automatic fuel selection: propane is the priority fuel, so the engine uses propane as soon as the cylinder valve is opened and falls back to gasoline when the valve is closed or the cylinder runs low. Amazon's bullets claim a combined run of up to 21.2 hours at 25 percent load; the maker documents we read do not repeat that number.

The supplied propane hose and regulator is listed for standard 20, 30 and 40 pound cylinders with Type 1 fittings. For gasoline the manual asks for 87 octane unleaded minimum and says not to use E15 or E85. Follow the manual's own fuel-connection and leak-check steps rather than improvising, and keep the propane valve closed when running on gasoline.

Outlets: two 30-amp locking receptacles and a 120/240V switch

The manual's control panel lists a 5-20R duplex at 20 amps, an L5-30R twist-lock at 30 amps and 120 volts, and an L14-30R twist-lock at 30 amps and 120 or 240 volts, plus a 12V 8.3-amp DC socket and USB-A and USB-C ports. A voltage selector must be set to 240V for the L14-30R's 240-volt output; in that position the 120-volt outlets stop working, and the switch should only be moved with the generator off.

The panel does not list a TT-30R, yet one line of the manual's voltage-selector text mentions a TT-30R, and the spec sheet notes maximum output comes from a 14-50R that appears nowhere in its outlet list. A 30 amp RV adapter is included, but neither document says which plugs it joins. For a house connection, the manual requires a listed transfer switch installed by a licensed electrician.

Parallel use needs a second SUA7600iED and a separately bought kit

The manual says to parallel only two identical SUA7600iED generators, using A-iPower approved cables and a parallel operation kit that is purchased separately, with the two units at least 20 inches apart so exhaust heat does not damage the other shell. The spec sheet names the kit as PK12000 and says it is sold separately.

The same spec sheet also lists parallel cables among the included items, while the manual's own ten-item parts list does not. Treat the kit as an extra purchase unless A-iPower tells you otherwise, and do not assume another model will pair with this one, since the manual warns an incompatible partner can cause low voltage output.

Starting, the CO shutoff, oil schedule and warranty

Starting is by recoil or push-button electric start. A 12V 5Ah sealed lead acid battery ships pre-installed with its quick-connect plug separated; you join it before first start, and the included float charger keeps it topped up from a wall outlet. The CO shutoff is called CO Sentry on the product page and CO WATCH-GUARD in the manual, which says it shuts the engine off when CO builds up, only monitors while running, and does not replace CO alarms indoors.

The manual says outdoor use only, far from windows, doors and vents; read its location pages before first start. Oil is 10W-30 at 0.7 liters, checked before each use or every 8 hours, changed after the first 5 hours, again at 25 hours or one month, then every 100 hours or six months, with the first 5 hours kept at or under half load. The warranty is three years residential, parts and labor in year one and parts only in years two and three, and one year for commercial or rental use; Amazon's field says two years.
