Jacob Marshall, President;John Dunham, VP, Sales;Scott Castagno, Director, Engineering;Brad Schmidt, Sr. Director, OperationFounded by a team of seasoned experts with over 15 years of experience in utility-scale power conversion, Apex was established to address the need for U.S.-based solutions tailored to the American energy market. After working for industry giants such as Power-One, ABB, SMA, SunPower, and Power Electronics, the founders recognized limitations in how traditional companies addressed the specific needs of the U.S. energy sector. Seizing the opportunity to lead in American innovation, they established Apex with a vision to pioneer the next generation of power conversion technology.
“At the forefront of U.S. manufacturing, we’re not just building solutions-we’re leading the new charge in utility-scale conversion to drive innovation and power the future of American energy,” says Jacob Marshall, President of Apex Power Conversion.
Power and Accountability at Its Core
Apex’s approach is built on two key principles: power and accountability. The company designs premium products without the premium price tag, remaining fully committed to transparency and customer support. Apex provides ongoing service and empowers its customers’ operations and maintenance (O&M) teams to become expert operators. Through training, certification, and support, Apex enables customers to independently manage maintenance and service, optimizing performance at every step.
Solar Conversion and Energy Storage Excellence
Apex operates at the intersection of two critical markets: large-scale solar conversion and energy storage. Its products are engineered for high efficiency, reliability, and flexibility, ensuring optimal performance across all environmental conditions.
The company’s solar conversion solutions excel in diverse environments. Its PV inverters deliver 4.5 megawatts of power at temperatures up to 45°C, over 4 megawatts at 50°C, and maintain more than 3.5 megawatts at 60°C, ensuring reliable operation even in challenging settings. These inverters also operate at temperatures as low as -40°C. Each unit includes six 750-kilowatt independent inverters, enhancing both reliability and flexibility.
Apex’s systems feature dual-layer modularity, where each power module functions as a fully capable inverter with independent logic and control systems embedded within each module. Unlike competing systems that rely on a central unit to direct power modules, Apex’s modules are self-operating. If one module fails, the remaining five continue to operate, minimizing downtime. A second layer of modularity incorporates dual DC disconnects and AC output breakers, allowing each half of the system-or three power modules-to be fully isolated while the other half remains operational.
Apex also offers tailored solutions with up to six maximum power point trackers (MPPTs) for optimal performance across varied terrains, particularly beneficial for long DC cable runs that typically require string inverters.
The company’s custom inverters are designed to last 30 years on-site, providing clients with the necessary support to maximize system performance and reliability. This customer-centric philosophy extends to all aspects of its operations, logistics, and commercial processes.
Our strategy is to grow with the market, for the market, ensuring that we meet the increasing demand for utility-scale power conversion systems by developing a strong local manufacturing presence
Its energy storage systems deliver a full 4.5-megawatt output at 50°C and maintain over 3.7 megawatts in extreme conditions up to 60°C, making them ideal for high-temperature regions such as deserts, where energy storage systems often struggle to maintain capacity. The modular input design supports large battery banks with up to six inputs and can handle short-circuit currents of 250 kiloamps each, providing greater energy density and extended durations.
Apex’s modular systems offer premium features, functionalities, and grid capabilities without imposing a premium price.
Success in the Real World
Apex’s technology excels in real-world applications, such as in the Mojave Desert, where energy storage systems often fail to meet performance standards. Competitors’ inverters frequently overheat and reduce power output, resulting in contract penalties. Apex’s advanced energy storage and inverter technology maintains full capacity under extreme conditions, ensuring compliance with power purchase agreements (PPAs) and providing peace of mind to project developers and operators.
Thanks to its high-margin design, Apex’s platform performs even better in less harsh conditions and at lower temperatures, further extending its lifetime.
Apex’s energy storage converter also features a unique input system that allows independent control and simultaneous charging and discharging of different inputs. This capability ensures perfectly balanced battery banks, boosting overall energy output and enhancing system efficiency.
Strategic Growth Plan for the Future of Energy
Apex is focused on both current needs and future opportunities through a strategic growth plan. It aims to deploy 1 gigawatt of converters in 2025, scaling up to 3 gigawatts by 2026. This deliberate approach ensures the company meets market demand effectively without risking overextension.
Starting in 2026, Apex plans to manufacture its products in the U.S., aligning with its mission to support the domestic market. U.S.-manufactured products will help customers qualify for additional tax incentives, enhancing the value of its offerings.
“Our strategy is to grow with the market, for the market, ensuring we meet the increasing demand for utility-scale power conversion systems by developing a strong local manufacturing presence,” says Marshall.

The company is also pushing the boundaries of technology by pioneering 2KV DC converters, which are critical as utility-scale PV arrays and battery storage systems evolve. Apex aims to lead the shift toward 2000-volt PV arrays and, eventually, 2000-volt battery systems, becoming the preferred choice for those advancing into this next phase of technology. It is already collaborating with component manufacturers to ensure fuses, breakers, and other 2KV-rated components are available for seamless implementation.
Simplifying the Complexities of Power Conversion
Apex is not just another player in the energy market-it is transforming the industry by simplifying the complex world of power conversion and energy storage. The company is setting a new standard for utility-scale power conversion and energy storage by designing systems that perform in the toughest conditions, offering modular solutions, and planning for a future where U.S. manufacturing plays a central role.
Apex’s technology is user-friendly, reliable, and ready to tackle the most demanding projects, ensuring smooth operation even in the harshest environments.
