Description

Simpson SIG22PK Inverter Generator Parallel Link Kit

The Simpson SIG22PK Inverter Generator Parallel Link Kit is an electrical power combining module engineered to link two compatible Simpson inverter generators to deliver up to 6,600 running watts of continuous clean power. Featuring an integrated 30 Amp circuit breaker switch, dual IP44 weatherproof power outlets, LED wattage output indicator lights, and dual grounding leads, this unit connects directly to PGMA G300-2018 standard parallel link ports. Designed for jobsite power distribution, emergency home backup systems, and RV power hookups, this parallel box solves insufficient wattage capacity, electrical overload tripping, and multi-generator synchronization challenges when operating high-draw machinery.

Best Used For:

  • Jobsite High-Draw Power Tool Sizing: Combining two portable inverter generators to operate heavy-duty air compressors, table saws, and concrete cutters simultaneously.
  • Recreational Vehicle (RV) Power Hookups: Doubling generator output to run 30 Amp RV air conditioning units and onboard appliances cleanly without tripping breakers.
  • Emergency Home Backup Generation: Parallel-linking generators during power outages to energize critical 120V household circuits, refrigerators, and medical equipment.

Key Performance & Safety Features

  • Dual Generator Wattage Doubling: Links two compatible Simpson inverters to provide up to 6,600 continuous running watts for heavy electrical loads.
  • Integrated 30A Circuit Breaker: Thermal overload breaker switch instantly protects connected electronics and generator alternators from current spikes.
  • IP44 Weatherproof Outlet Receptacles: Dual sealed output sockets prevent water splash and debris ingress on outdoor jobsite locations.
  • Real-Time LED Wattage Output Display: Visual LED status lights monitor continuous electrical load levels to prevent unexpected overload conditions.
  • 50-State EPA & CARB Compliance: Certified electrical accessory compliant with environmental safety standards across all 50 U.S. states.

What's Included

  • (1) Simpson SIG22PK Parallel Link Box
  • (2) Heavy-Duty Grounding Wires
