WEN GNA50i 50-Amp Parallel Kit
The WEN GNA50i parallel kit is designed to connect two WEN inverter generators, increasing the available wattage on each connected panel. Best for owners already running WEN units who want a straightforward upgrade path to more power. The kit handles up to 50 amps and 6000 watts of output, making it suitable for air conditioners, sump pumps, and other critical loads when paired correctly. Caution: verify that both generators have compatible parallel ports and that you do not exceed generator or cable limits.
Champion ParaLINK 50-Amp Kit
Champion’s ParaLINK 50-Amp kit is ideal for linking two 2500-watt or higher Champion inverter generators and is RV-ready with a standard 50A outlet. It offers quick clip-on connections, enabling easier setup for those needing to start two RV air conditioners or other demanding loads. Best for Champion owners seeking minimal fuss and robust transfer capabilities. Limitation: designed specifically for Champion models; cross-brand use may require other adapters or kits.
MECMO 50 Amp Parallel Cord Kit
The MECMO kit emphasizes cross-model compatibility to double output, with straightforward access to a standard 120V 50A RV outlet. It supports several popular inverter brands, enabling two units to share load and start higher-demand devices. Best for buyers who want flexibility across different inverter brands. Caution: always confirm that both generators support parallel operation and meet the kit’s load requirements.
Westinghouse 50 Amp Parallel Cord
Westinghouse emphasizes a compact, plug-and-play system with illuminated plugs and switches, avoiding bulky junction boxes or extra ground wiring. Best for RV setups or job sites where ease of use matters. Reason for selection: straightforward extension of power with reliable outlets. Limitation: may be less flexible with non-Westinghouse inverters if port interfaces differ.
Cummins 50A Parallel Kit for Onan P4500i
This Cummins kit targets Onan P4500i users, offering a compact solution for duplicating power between Onan-compatible inverters. Best for Onan/P4500i owners seeking a tailored parallel option. Caution: compatibility is strongest with specific Cummins/Onan series; check model alignment before purchase.
Buying Guide
What to check before buying a 50A parallel kit:
- Compatibility: Confirm both generators have parallel ports and that the kit supports your exact models. Some lines are brand-specific.
- Output needs: Estimate your peak load to choose a kit that supports the total amperage and wattage you require.
- Portability: Consider kit weight, cable length, and ease of setup for frequent transport or campsite use.
- Safety features: Look for grounded outlets, illuminated indicators, and robust connectors to reduce misplugging risks.
- Durability: Weather resistance and connector construction matter if you use in outdoor environments or on job sites.
Practical comparison tips
- Best for existing brand ecosystems: If you already own WEN or Champion units, the corresponding kits often provide the smoothest integration.
- Cross-brand flexibility: MECMO and similar cross-brand kits offer versatility but verify compatibility with your specific models.
- RV readiness: If RV air conditioning is a priority, prioritize kits that include a standard 50A RV outlet.
Common questions
- Can any two inverter generators be paralleled? Not all; check compatibility and the kit’s listed models.
- Is parallel operation always necessary for more power? No—if a single generator already meets your peak load, a parallel kit may be unnecessary.
- Do parallel kits affect warranty? Some brands specify installation requirements; review manufacturer policies.
- What maintenance is required for these kits? Inspect cables, connectors, and outlets for wear; keep connectors clean and dry.
- Is a surge protector recommended? For sensitive electronics, using a surge protector alongside a parallel setup can help.
- Can I mix different voltages? Typically, kits are designed for identical voltage systems; mismatched voltages can cause issues.

FAQ
- Q: Do I need a parallel kit if my generators already have high wattage? A: If your loads exceed a single unit’s capability, a parallel kit can help—but verify that your units can operate in parallel safely.
- Q: Can I use a 50A parallel kit with 30A or 20A generators? A: Parallel kits are designed for specific amperage and port compatibility; use only recommended configurations.
- Q: Are there safety steps I should follow before wiring in parallel? A: Ensure both units are off, ground correctly, and follow manufacturer assembly instructions to avoid electrical hazards.
- Q: Is professional installation required? A: Not usually, but if you are unsure about electrical work, consult a qualified technician.
- Q: Will parallel operation double the runtime? A: Not directly; runtime depends on fuel capacity and load. Parallel operation increases available watts, not necessarily fuel duration.
