Generac PM4500 CO (49-State)

Robust Gas-Powered Generator with COsense® Safety

Meet the PM4500 CO 49ST—a resolute, open-frame generator built to deliver reliable power while vigilantly protecting you from carbon monoxide hazards via its COsense® technology.

At a hearty 4,500 watts starting and 3,600 watts running, it handles your essential tools, appliances, and DIY projects without drama. With its thoughtful design—think POWERDIAL™ for one-dial start-up, low-oil shutdown, fuel gauge, never-flat wheels, and hour meter—it’s a generator that just makes sense.

Key Features

COsense® Safety Shutdown: Monitors CO levels and shuts off if danger looms.
POWERDIAL™ Recoil Start: Combines Off / Run / Cold-Start in a single intuitive dial.
Long Runtime: 5-gallon steel tank delivers up to 19 hr at 25% load or 14 hr at 50% load.
Generac 224 cc OHV Engine: Reliable and durable with splash lubrication and low-oil shutdown.
Portability & Protection: 8″ never-flat wheels, a sturdy steel frame, fold-down handle, and covered outlets protect from debris.
Monitoring & Maintenance: Hour meter for tracking runtime and service intervals, plus a fuel gauge.
Outlets and Breakers: Includes (4) 120 V 20 A GFCI outlets, one 30 A L5-30R twist-lock, and built-in circuit breakers.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Jacob B

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
