What Makes the ATESS Delta US standard 220V 100KW hybrid inverter (included tranformer) - ATESS HPS100-US-220D Stand Out?

This inverter is a high-capacity, hybrid-ready system built for demanding environments where consistent power and scalability are essential. Equipped with an integrated transformer, the ATESS HPS100-US-220D supports stable voltage output, smooth switching operations, and enhanced safety for critical installations. The transformer adds an extra layer of performance reliability, making the unit ideal for applications that require higher surge tolerance and isolated output.

Whether used in commercial solar plants, microgrid systems, energy storage solutions, EV charging hubs, or large-scale backup configurations, this inverter ensures superior performance with minimal downtime. The hybrid design makes it future-ready and adaptable to both current and expanding energy needs.

High-Efficiency Power Conversion

One of the strongest features of the ATESS Delta US standard 220V 100KW hybrid inverter - ATESS HPS100-US-220D is its exceptional energy conversion efficiency. The system minimizes power loss during conversion from DC to AC or when managing multiple energy sources. This high efficiency results in improved ROI and smooth performance across diverse operating conditions.

The inverter also supports advanced MPPT (Maximum Power Point Tracking), ensuring solar arrays operate at optimal efficiency even in changing weather conditions. For commercial users, this directly translates to reduced operational costs and maximized solar output.

Smart Hybrid Control and Energy Optimization

Being a hybrid inverter, the unit intelligently manages grid power, solar energy, and battery storage. It decides in real time which source should be prioritized to maintain the best possible efficiency. This dynamic distribution of power helps businesses reduce peak electricity charges, cut dependency on the grid, and store excess solar energy for later use.

The ATESS HPS100-US-220D also includes load shifting, peak shaving, and scheduled charging modes. These functions give facility managers more control over energy patterns, allowing them to reduce power bills and improve energy stability.

Enhanced Safety and Stability With Included Transformer

The integrated transformer in the ATESS Delta US standard 220V 100KW hybrid inverter (included tranformer) - ATESS HPS100-US-220D provides isolated output, increased surge protection, and improved grid compatibility. This is especially important for industries where uninterrupted power quality is mandatory.

The transformer also helps manage harmonic distortion, improving system reliability and extending the lifespan of connected equipment. For sites with sensitive electronics or heavy machinery, this feature is crucial.

Rugged Design for Demanding Applications

The inverter is designed using industrial-grade components that ensure long-term endurance under harsh operating conditions. Its thermal management system keeps internal components cool, preventing overheating and ensuring optimal performance even during continuous heavy loads. Whether installed indoors or outdoors, the system maintains stable operation with minimal maintenance.

Easy Integration and Remote Monitoring

The system supports multiple communication protocols, allowing real-time tracking of performance data, grid activity, energy flow, and system health. Users can remotely monitor and configure settings, improving maintenance efficiency and reducing the need for on-site intervention.

This flexibility allows businesses to make data-driven decisions, monitor energy savings, and ensure uninterrupted operations.

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.

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.

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!

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.
