You've got a capable inverter generator, but the moment you run the AC, the coffee maker, and charge a few devices at once, you're right at the edge of its limits. That's a frustrating position to be in, especially when you're miles from the nearest hookup or the grid goes down at home.
Push past that ceiling and something gives. The generator bogs down, a breaker trips, or you're stuck making hard choices about what you can and can't run. For RV travelers and emergency backup users alike, that's not acceptable.
The Pulsar PARALLEL BOX KIT 30A RV (model PGIPAIRB2) solves this cleanly. Connect two compatible Pulsar inverter generators through this kit and you effectively double your available output, all without stepping up to a heavy, noisy conventional generator. Same compact footprint. Twice the capability.
The PGIPAIRB2 is built around one straightforward goal: let two Pulsar inverter generators work as one. Here's what makes it a reliable way to do that.
TT-30R RV Outlet. The industry-standard 30-amp RV receptacle means you can connect directly to your RV or to any 30-amp load without fumbling for an adapter. That's the right connector for most Class A, B, and C motorhomes and travel trailers running a 30-amp service.
120V / 30A / 60Hz Output. The kit delivers household-standard voltage and frequency. That matters for inverter-sensitive devices like CPAP machines, laptops, and modern appliances that don't tolerate dirty power well. Inverter generators paired through this kit maintain the clean sine wave output those devices require.
3-Foot Cable Length. A shorter cable keeps resistance low and your setup organized. Position both generators side by side, connect the kit, and you have a tidy, safe arrangement with no excessive cable slack on the ground.
Broad Generator Compatibility. The PGIPAIRB2 is confirmed compatible with the following Pulsar models: FG2500iS, G150GN, G2319N, G240BN, PG2200BIS, PG2300IS, PG2300ISCO. If you own one of these and are considering a second unit, this kit is the link between them.
Ready to get more out of your Pulsar inverter generator setup? Add the PARALLEL BOX KIT 30A RV to your cart and make it happen.
This kit earns its place in a few specific situations where a single generator simply isn't enough.
Full-Time and Weekend RV Travel. Running a rooftop air conditioner alongside a microwave, refrigerator, and a few device chargers can easily push past what a single 2,000-2,500W generator delivers. Two generators in parallel through the PGIPAIRB2 give you the headroom to run your rig comfortably without sacrificing anything.
Emergency Home Backup. When the power goes out, you want to run more than just a few lights. Pairing two inverter generators lets you keep your refrigerator, a window AC unit, medical equipment, and essential lighting going simultaneously through a safe, organized connection.
Outdoor Events and Tailgating. Food trucks, outdoor kitchens, vendor setups, and tailgate parties all demand more continuous power than a solo unit can sustain for hours. The parallel kit lets you scale up without renting or buying a large commercial generator.
Remote Worksites. Contractors and tradespeople who already own a compatible Pulsar generator can add a second unit and this kit to run heavier tools, compressors, or lighting rigs that would otherwise require a much larger generator to transport.
If any of these scenarios sound familiar, the Pulsar PGIPAIRB2 is worth a close look. Reach out to our team if you want help confirming it fits your specific setup before you order.
The obvious alternative to a parallel kit is simply buying a larger single generator. On paper, that sounds straightforward. In practice, it comes with real trade-offs that many buyers regret after the fact.
Larger conventional generators are loud, heavy, and burn significantly more fuel whether you're using 30% of their capacity or 100%. Inverter generators, by contrast, throttle down under light loads and sip fuel accordingly. When you run two inverter generators through a parallel kit, each one is operating in its efficient load range, which typically means quieter operation and better fuel economy compared to a single oversized unit running near-idle for hours.
Transport is another factor. Two 55-65 lb inverter generators are far easier to load, carry, and store than a single 200+ lb conventional generator. If you ever need only one generator, you have that option. You're not locked into running a massive unit for a small load.
Pulsar has built a reputation for producing accessible, capable inverter generators with solid real-world performance. The PGIPAIRB2 is a genuine Pulsar accessory, engineered to work with their specific generator models, not a generic third-party adapter that may not interface correctly. Buying an accessory made by the same manufacturer as your generator removes compatibility guesswork entirely.
It's a practical, cost-effective path to more power without starting over with a completely different machine.

The PGIPAIRB2 connects two compatible Pulsar inverter generators through a single parallel interface box, combining their output into one usable power source. The result is a combined 120V, 30-amp output delivered through the TT-30R RV outlet. Both generators must be the same model or confirmed compatible models for parallel operation to work correctly.
The kit is confirmed compatible with the FG2500iS, G150GN, G2319N, G240BN, PG2200BIS, PG2300IS, and PG2300ISCO. If you own two of the same model from this list, the PGIPAIRB2 is designed to link them. Using models outside this list is not recommended, as electrical interfaces vary between generator families.
Pulsar recommends pairing two generators of the same model for optimal parallel performance and balanced load sharing. Mixing different models, even within the compatible list, can cause uneven load distribution and may affect output stability. Sticking to a matched pair gives you the most reliable and predictable results.
Yes. The TT-30R outlet on the PGIPAIRB2 is the standard 30-amp RV receptacle used on the majority of travel trailers, fifth wheels, and Class C motorhomes with 30-amp electrical systems. You can plug your RV's shore power cord directly into the kit without any adapter. The output is 120V at 30 amps, which matches a standard 30-amp RV service.
It depends on what you already own. If you already have a compatible Pulsar inverter generator and want more power, adding a second generator and the PGIPAIRB2 kit often costs less than replacing your current unit with a much larger generator. You also retain the fuel efficiency and noise advantages of inverter technology, which a large conventional generator typically can't match.
