Simpson SIG22PK Parallel Box Overview
The Simpson SIG22PK Parallel Box is a compact accessory that links two compatible Simpson inverter generators so their output can be combined. Paired with two SIG3632E models, the combined output reaches up to 6,600 running watts, which opens the door to larger loads than a single unit would handle.
The source describes it as a rugged, weather-ready panel for jobsites, home backup and tailgating. It is meant for situations where one inverter generator is not enough, such as a larger RV, several power tools running together, or essential household appliances. The generators themselves, for example the SIG2218 or SIG3632E, are sold separately. The package contains the parallel box and two grounding wires. The specification table gives a combined running-watt range of 3,300 W at the minimum to 6,600 W at the maximum, and it lists the unit for outdoor and jobsite use. The idea, as the source puts it, is to take control of your power needs with combined inverter technology that delivers clean, stable power.

Who It’s For
This parallel box suits owners of compatible Simpson inverter generators who sometimes need more output than one machine delivers, whether for a worksite, an RV, backup power at home or a tailgate. It is not intended for other brands of generator, since compatibility is limited to Simpson inverters with the parallel link outlet.
