This makes the PMI4500i worth considering for customers who want a generator that offers additional backup power options beyond ordinary manual operation.
Important: Additional Equipment Required
Automatic mains-failure operation is not included with the standard generator. A compatible automatic mains-failure kit and suitable electrical installation are required separately.
Any connection to household electrical wiring must be designed and installed by a licensed electrician using appropriate transfer equipment. Confirm generator and accessory compatibility before purchasing.
