The Return of the PSS40

We are closing up the gap in our liquid-cooled, gaseous generators; by adding the PSS40 and PSS45.

Meet The New PSS Units

As WINCO continues to grow, we are dedicated to provide a bigger offering of power nodes. We saw an opportunity to not only bring back the PSS40, but also offer a PSS45.

  • Conform to UL2200 and CSA standards.

Meet The Origin Engine

We are excited to introduce a new engine partner, Origin Engines. Origin has more than 30 years in the engine industry plus the years of the founder’s early interests in high-performance engines.

We are using a prime rated, Origin 4.3L engine on the PSS40 and PSS45. This engine is based on the GM 4.3L that we are all used to. Another familiar design feature is the ECU and connections. The ECU is built by E Controls.

Origin Engines are built from the block, up. Their engines are built for the industrial market. Which provides engines that won’t change unless the power generation industry needs it to, not the car industry.


Just like the rest of our liquid-cooled standby units, the Origin engine is EPA Certified.


The Origin 4.3L is a prime rated engine. Simply add a catalyst to bring the generator set to a prime source of power.

We are continually updating and creating new generators. Stay tuned!

A Manual Transfer Switch for GFCI and Bonded Neutral Generators

WINCO portable generators are designed with a bonded neutral, the neutral and ground tied together inside the panel. This allows the generator to be safely used in portable configurations.

Whenever you connect a portable generator to a building’s electrical system the NEC code requires you to brake the neutral to ground bond on the generator. This creates a new risk if the portable generator is used as both a home back-up and mobile power source since changing the neutral to ground bond should be left to an experienced electrician.

To solve this problem Winco only offers manual transfer switches for our portable generators that are compatible with bonded neutral generators. An additional benefit of these switches is that they also work with our models that provide full panel GFCI protections.

WINCO offers the Reliance XR series manual transfer switches.

The Reliance XR series are three pole manual transfer switches. By switching the neutral these manual transfer switches meet the NEC code allowing direct connection of bonded neutral generators and are compatible with GFCI protected switches.

WL22000VE Circuit Breaker Upgrade

Sometimes, a vender discontinues an item, which happed to us with an 80 amp shunt breaker. This breaker disconnects the power of the Anderson connector when the cover is opened when a plug is not in place on our WL22000VE-03/B model.

We transitioned from the 80 amp to a 100 amp, 80% rated breaker. This change had us increase the wire size to match the new breaker maximum rating.

Let’s compare the WL22000VE-03/B with the new version, the WL22000VE-03/C.

The costs will remain the same going forward. We still offer the WL22000VE-03/A with the GFCI protected panel with split distribution for customers that do not need all of their output from one receptacle. This product remains unaffected.  

Please evaluate your installation practices for compatibility with this change.

WINCO – Bringing More Power

Introducing the expanded DR line!

With improvements to our facility’s capabilities, we have expanded our diesel line by offering new Volvo powered models. This provides more power without the need of paralleling two units. The four new models provide 450kW, 500kW, 550kW, and 600kW.

The Engine


16L, Tier II

When designing these units, we needed a strong, dependable engine brand that could carry the load demand. Volvo has 100 years of industrial engine experience. These engines are built with prime power durability, even though the EPA doesn’t allow them for prime applications.


Optional Housing
Our housing has a 77 Dba rating, the best you will find with standard housing.

LED Lighting
Standard on all housed units, automatic LED lighting makes servicing easier.

Heavy Duty Stamford PMG
The PMG allows power to the AVR to be kept near constant. This allows the AVR to quickly recover the voltage of the generator back to its nominal preset value. 

Paralleling Options

These units come with paralleling options. Paralleling allows you to quote large projects while being cost effective. The DSE8610 MKII controller represents the latest in complex load sharing & synchronizing control technology. The module has been designed to allow the operator to start, stop and synchronize the generator. If required, transfer the load to the generator either manually or automatically.

Find the right 450kW – 600kW diesel standby for your project here. You will also find spec sheets, engine information and more by going to their product pages.

As I always say “Unleash the Power”!
