Product Overview

The Generac PWRgenerator (Model 8005) is a 9,000W DC-coupled backup generator engineered to integrate natively with the Generac PWRcell Solar + Battery Storage system — providing extended days or even weeks of off-grid power resilience when solar generation is insufficient or grid power is unavailable. Operating on Generac's REbus DC 380V platform, it charges the PWRcell battery bank directly in DC, eliminating the conversion losses inherent in AC-coupled generator configurations. Rated at 9,000W continuous output on both liquid propane (LP) and natural gas (NG), operating at just 61 dBA at normal load, and requiring service only every 500 hours of runtime, the PWRgenerator is purpose-built for quiet, efficient, long-duration home energy backup — fully managed via the PWRview home energy app and certified to UL2200, CSA, and EPA standards.

Key Features

Native PWRcell DC-Coupled Integration: Unlike conventional AC-coupled generators that waste energy through double conversion, the PWRgenerator connects directly to the PWRcell battery on Generac's REbus DC 380V bus — charging the battery bank with maximum efficiency and enabling seamless, automatic failover during grid outages or extended periods of low solar production without any manual intervention.

Extended Off-Grid Runtime — Days to Weeks: Paired with the PWRcell Solar + Battery Storage system, the PWRgenerator dramatically extends whole-home backup capability beyond what battery-only systems can provide — delivering continuous, renewable-backed energy independence for days or weeks during prolonged grid outages, natural disasters, or extended periods of cloudy weather with low solar yield.

Quiet Operation — 61 dBA at Normal Load: At just 61 dBA at 23 feet under normal load — and as low as 51 dBA in low-speed exercise mode — the PWRgenerator operates at a significantly quieter level than conventional standby generators, making it suitable for residential neighborhoods, HOA-regulated properties, and any installation where noise is a concern during extended backup operation.

Dual-Fuel LP & Natural Gas Compatibility: Rated at a full 9,000W continuous output on both liquid propane and natural gas, the PWRgenerator offers fuel flexibility that allows homeowners to connect to their existing natural gas line or maintain a propane tank — ensuring uninterrupted backup capability regardless of which fuel source is most accessible or cost-effective at the installation site.

PWRview App Monitoring & Low-Maintenance Design: Fully integrated with Generac's PWRview home energy management app, the PWRgenerator provides real-time status monitoring, automated exercise scheduling, and system-wide energy visibility from any smartphone — while its 500-hour service interval and once-monthly 5-minute exercise cycle dramatically reduce ongoing maintenance requirements compared to traditional standby generators.

How It Works

The PWRgenerator continuously monitors the PWRcell battery's state of charge via the REbus DC 380V platform. When battery charge falls below a user-configured threshold — due to grid outage, extended low-solar conditions, or high household demand — the generator automatically starts and begins charging the battery bank directly in DC, bypassing the AC inverter stage entirely to eliminate conversion losses. The PWRview app provides real-time visibility into this process, allowing homeowners to set charge thresholds, monitor runtime, and track fuel consumption from their smartphone.

REbus DC Coupling Technology: The REbus DC 380V platform enables the PWRgenerator to charge the PWRcell battery directly without AC-to-DC conversion — delivering higher round-trip charging efficiency than AC-coupled alternatives and allowing the generator, solar panels, and battery storage system to share a common DC bus for coordinated, loss-minimized energy management across the entire home energy system.

PWRview App & Automated Control: The PWRview home energy management app connects to the PWRgenerator and all PWRcell system components via the home's local network — providing live generator status, battery state of charge, solar production data, and automated exercise scheduling, while allowing homeowners to configure backup thresholds and monitor system health remotely from any iOS or Android device.

Automatic Exercise & Self-Maintenance: The PWRgenerator performs a brief 5-minute automated exercise cycle once per month at low speed — keeping the engine lubricated, the fuel system primed, and all mechanical components in ready condition without requiring manual activation, ensuring the generator is fully prepared to deliver instant, reliable backup power at any time it is needed.

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.
