Product Overview

The Generac RG04854GNAX 48kW 3-Phase 120/208V Gas Generator is part of the Protector QS Series, designed to deliver dependable backup power for commercial, industrial, and large-scale residential needs. This generator provides efficient operation, quiet performance, and long-lasting durability, making it ideal for ensuring continuous operation during power outages.

Key Benefits

High-Capacity 48kW Power Output: Delivers up to 48kW of power suitable for 3-phase systems at 120/208V, ensuring consistent energy for sensitive and high-load applications.

Liquid-Cooled Engine Design: Maintains optimal operating temperatures, supporting extended runtime and high performance under continuous loads.

Commercial-Grade Durability: Features a corrosion-resistant aluminum enclosure and heavy-duty components for reliable performance even in harsh environmental conditions.

Quiet-Test™ Self-Check Mode: Equipped with Generac's patented Quiet-Test mode, the unit self-runs at a lower RPM for a quieter and more fuel-efficient test cycle.

Flexible Fuel Options: Compatible with both natural gas and liquid propane, ensuring adaptable and efficient operation based on fuel availability.

How It Works

The Generac RG04854GNAX provides automatic backup power with intelligent monitoring and control for reliable commercial and industrial applications.

Automatic Backup Activation: Upon power failure, the generator automatically detects the outage and restores power to essential circuits within seconds, ensuring continuous operation.

Integrated Smart Control: The digital control system monitors voltage, current, and system health, optimizing performance and providing remote monitoring capabilities for added convenience.

Seamless Return to Utility: Once utility power is restored, the system safely transfers loads back and returns to standby mode, ready for the next outage.

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.

Brian H

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.
