Delta Transformers Introduces Renewable Energy Transformers Built for Solar, Wind, and Energy Storage Systems

November 10, 2025

As the demand for clean energy continues to grow, Delta Transformers is proud to announce the launch of its new Renewable Energy Transformers, engineered specifically for solar, energy storage, wind, and hybrid systems. These transformers are designed to deliver high efficiency, reliable performance, and flexible integration for the energy systems of tomorrow.

Delta renewable energy transformers enable precise voltage adjustment between renewable generation equipment and the utility grid. Whether used in grid-tied or hybrid systems, they ensure efficient bi-directional energy transfer, whether power flows from solar inverters to the grid or from the grid back to battery storage.

“We are excited to introduce our new renewable energy transformer, that is designed to support the evolving needs of clean energy systems. By combining efficiency, reliability, and flexibility, we help our customers build sustainable solutions that meet today’s challenges and tomorrow’s opportunities,” said Mario Mongrain, National Sales Manager at Delta Transformers.

Bi-Directional Power Flow

Whether energy is flowing from solar inverters to the grid, or from the grid back to a battery storage system, Delta’s transformers are built to reliably manage power in either direction. Designed for today’s renewable energy systems, they provide both flexibility and efficiency in demanding environments, ensuring consistent performance even in the most challenging conditions.

Key Benefits:

• Flexible System Design: Built for bi-directional power flow, ensuring compliance with electrical codes and supporting dynamic energy exchange between the grid and renewable sources.
• Tailored for Renewable Energy: Simplified integration with clearly labeled windings for inverter and grid sides and adjustment taps placed for renewable configurations.
• Easier Installation: Pre-installed lugs (up to 300 kVA), bottom cable entry, and standard Type 3R outdoor enclosures save valuable labor time on site.
• Reliable Outdoor Performance: Available with low-temperature rise and thermal sensing options, designed for high load factors and harsh environments.
• Equipment Protection: Optimized inrush currents help prevent nuisance tripping and protect sensitive components, reducing downtime and maintenance costs.
• Energy Savings: Meets or exceeds SOR/2018-201 (NRCan 2019) and ON Reg. 201/19 efficiency standards, with high-efficiency options for energy-conscious projects. 

This renewable energy transformer reflects Delta’s commitment to innovation, sustainability, and advancing electrical technology to power a greener future.
