M: One Inverter

for All Uses

The modular M System is a scalable building block with world-class power density and easy installation. Made in the USA with silicon carbide technology and a low-maintenance design, M delivers advanced, reliable performance for PV and BESS. With two US factories scaling to 15+ GW/year and the capability for a 100% USA Domestic Content supply chain, EPC Power is ready to meet growing demand for high-quality energy solutions.

Innovative Engineering

The M System has been developed to offer a straightforward and simple modular solution Utility-grade solar and energy storage systems in both UL and IEC markets. 

Modular Technology: Provides optimal flexibility

Our industry-leading inverter enables lean, efficient scaling on your site. Start small, or start big. Either way, the M will be there to meet your needs and support your site reliably.

Advanced Design: Will be of-the-moment even in the future 

We provide up to 8 or 10 DC inputs with wide AC and DC operating range. With M, upgrades, maintenance and augmentation keep your site up-to-date with maximum efficiency for longer than ever before.

Ease of Use: Simple installation and operation

Maximize your return on investment by selecting M for your site or project. The design makes it low maintenance with simple O&M requirements. On the off-chance it breaks, just remove and replace the module—keeping your site up and running even during repairs.

Look no Further: One inverter for all uses

Whatever your inverter need, it can be met by the M system. M is optimized for PV and for BESS. It’s built in the USA with silicone carbide technology and boasts >99% efficiency.

Modular, Cost-Effective Inverter


Smaller, faster, and cheaper, M is optimized for solar. It has no liquid cooling, higher efficiency, and smaller building blocks which future-proof the design. M provides the most flexibility in the industry for central inverters, built-in spare capabilities, lower install costs, lower shipping costs, and infinite production capacity.
