The FIRMAN Parallel Kit almost doubles your power by connecting two FIRMAN Inverter generators together. It can combine any two inverters from our FIRMAN inverter family, whether that would be our smaller 2100-watt or our larger 3300-watt generators. Integrated outlet covers come standard on our parallel kit to protect the outlets from dust and debris. We've also included an LED light under each outlet for improved visibility anytime. The 1210 parallel kit features one 50 Amp 14-50R outlet and one 30 Amp TT-30R outlet.
