GENERAC 7154 GP3300i Inverter, 50 ST/CSA

Yes, the GP3300i is RV-ready and will start and run rooftop air conditioners up to 13,500 BTU. It puts out 2500 running watts with 3300 surge watts, and Generac's PowerRush technology adds over 50 percent more starting capacity, which is what lets a 149 cc inverter unit pull a compressor of that size through startup.

No. The GP3300i does not carry OSHA-required GFCI outlets, so on a jobsite that mandates them you would need GFCI protection downstream of the generator rather than relying on the panel. The unit is CSA Certified, UL Listed and ETL Listed, and it is CARB compliant, so it can be sold and used in California.

Not as supplied. No automatic transfer switch is included with the GP3300i, and no power cord comes in the box either. It's a portable inverter sized for RV loads, tools, and sensitive electronics, not a standby unit wired to a panel. For whole-building automatic backup you want a standby generator with its own transfer switch rather than a 2500 watt portable.

About 4.5 hours per tank at half load, from a 1.06 gallon gasoline tank. That's an overnight-ish run for lights and a few tools, but not a full shift unrefueled, and there is no fuel gauge on the unit so you're watching the clock rather than a needle.

At 59.5 lbs it's a two-hand carry for most people using the built-in handle, and that is how it ships. No wheel kit is included and the unit is not towable. Assembled footprint is 24.0 x 13.8 x 21.3 inches, so it fits a truck toolbox or RV bay.

Pull start. There's no electric start and no battery to maintain. Starting, running and stopping all go through one PowerDial, so the sequence is set the dial and pull the recoil. Low oil shutdown is built in, which protects the 149 cc Generac OHV engine if the oil drops on a long unattended run.

Two reasons drive that choice: noise and power quality. The GP3300i is an inverter unit in an enclosed plastic housing that cuts sound emissions, which matters on campgrounds, occupied properties, and anywhere a crew has to work next to it. Inverter output also suits laptops, controls, and other sensitive electronics. The tradeoff is capacity, 2500 running / 3300 surge watts, so for a framing crew running multiple saws and a compressor a larger conventional open-frame set is the better fit.

The manufacturer part number is 7154, sold as the GP3300i Inverter, 50 ST/CSA. That is the CSA-certified configuration, and it's also UL Listed and ETL Listed. Ordering by 7154 gets the CSA variant specifically, which is what you want for Canadian jobs or any spec calling out CSA certification.

No. The 7154 GP3300i has no Bluetooth and no iOS or Android app support, and there's no hour meter on it either. Monitoring is done at the onboard control panel. If you need runtime tracking for a maintenance schedule across a fleet, you'll be logging hours manually.

Recommended oil capacity is 0.6 quart for the 149 cc Generac OHV engine, so a single quart bottle covers a change with margin. Worth stocking oil alongside the unit if you're putting it into an MRO or rental pool, since low oil shutdown will stop the engine rather than let it run dry.
