Champion 50-Amp ParaLINK Parallel Kit
Best for owners of two Champion inverter generators. This kit uses a standard 50A RV outlet and a quick-clip connection to unite two inverters. It’s an ideal choice when you need to start and run two 15,000 BTU RV air conditioners. The setup is straightforward, with a hand-tightened clamp for quick attachment. Choose this if your current power setup includes compatible Champion inverters and you want maximum RV-ready output.
Best for: Campers and RV users who want reliable, scalable power for high-demand appliances. Limitation: Works best within the Champion ecosystem; compatibility with non-Champion models may require additional adapters.
WEN GNA50i 50-Amp Parallel Kit
Best for linking two WEN inverter generators. This kit increases the wattage of the individual outlets on either connected generator panel and handles up to 50 amps and 6000 watts of output. It’s well-suited for users who own multiple WEN inverters and want a clean, cross-compatible setup. Caution: Verify that both generators have compatible parallel ports to avoid data mismatch or voltage imbalance.
MWEDP 40065 Generator Wheel Kit
Best for portable transport upgrades. This kit is a wheel replacement solution compatible with Champion inverter generators, featuring folding handles and never-flat tires for easier movement. It’s a practical add-on when you frequently relocate your parallel setup. Limitation: It’s a physical upgrade and doesn’t affect electrical performance directly; ensure your generator model is within the supported range.
MECMO 50 Amp Parallel Cord Kit
Best for cross-model compatibility and RV-ready power. This 50-Amp parallel cord kit is designed to work with many 50A inverter generators, providing 120V output and the ability to run two RV appliances or small air conditioners simultaneously. Use this if you want a flexible solution that can bridge different manufacturer brands. Caution: Always confirm that both generators are 50A RV-rated and compatible with the kit connectors.
Champion 100740 30-Amp ParaLINK
Best for two smaller inverters. This kit uses 30A connectors to parallel two 2000–3000W units, enabling enough power to start and run most 15,000 BTU RV air conditioners. It’s a strong choice for compact, quiet setups where space and weight matter. Better for lightweight or mid-range generator pairs; avoid this if you need higher output beyond 30A continuously.
WEN 50-Amp 12000-Watt 240V Kit
Best for 240V parallel setups. This kit supports 240V WEN inverter generators with three parallel ports and is not compatible with 120V-only models. Rated for up to 50A and 12000 watts, it’s ideal for larger, 240V-compatible systems. Choose this if your plan includes high-wrequency appliances or a need for 240V operation. Limitation: Not suitable for 120V-only generators or those without 240V outlets.
Journeyman-Pro Generator Parallel Kit
Best for steady, field-ready connectivity. This 30 Amp RV cord kit provides a parallel connection with right-angle plugs to minimize snagging and exposed plug length. The braided nylon sleeve and 12 AWG copper wiring support durable, easy handling in camp or work sites. Choose this if space is tight and you want a low-profile connection. Limitation: Parallel output tops at around 40 amps, which is lower than some 50A kits.
Buying Guide: How to Choose the Right Inverter Parallel Kit
What should you consider before buying a parallel kit? Start by matching the kit to the inverter generators you own or plan to buy. Look at compatibility, maximum output, and the type of outlets provided. Consider RV-compatibility if you’re powering air conditioners or RV appliances. Think about portability, weight, and ease of attachment. If you frequently camp or work off-grid, prioritize rugged construction and a kit that minimizes setup time.
- Connector standard: 30A vs 50A RV outlets; ensure your generators support the same RV outlet type.
- Wattage capacity: choose a kit that allows your combined inverters to reach or exceed your peak load.
- Compatibility: confirm both generators are listed as compatible with the chosen parallel kit.
- Portability: consider handles, wheels, and cable length for easy setup and movement.
- Safety: verify ETL or UL listings for outdoor use and weather resistance.
Frequently Asked Questions
- What is an inverter parallel kit used for?
It links two compatible inverter generators to increase total output, enabling higher-wattage appliances to run simultaneously.
- Do I need the same model to parallel generators?
Not always, but many kits require compatible models or brands. Always check the manufacturer’s compatibility list.
- Can a 30A kit be enough for RV air conditioners?
Sometimes yes, often best for smaller RV AC units; check your AC’s BTU and the kit’s continuous output rating.
- Is 240V parallel operation different from 120V?
Yes. 240V setups typically deliver higher power and require 240V-capable inverters and a 240V kit.
- What safety considerations exist for outdoor use?
Ensure weatherproof connections, use outdoor-rated cords, and follow all generator safety guidelines.
- How should I store parallel cables when not in use?
Keep in a protective pouch or bag, away from moisture, and coil loosely to avoid kinking.
