E-Saver SOL OPAL™ Series
Energy Efficient Transformers for Solar Applications
Specially designed for solar applications, the E-Saver SOL OPAL™ Series is a family of high performance low-voltage transformers optimized to deliver 25-40% less losses than a typical DOE 2016 compliant transformer, while contributing to LEED®, Net Zero and Sustainable Building designs.
E-Saver SOL OPAL™ Series (OPAL SOL) is an ultra-efficient, low-voltage, dry-type transformer optimized to maximize energy savings, exceeding DOE 2016* minimum efficiency requirement for solar applications.
The OPAL™ designed E-Saver SOL delivers top performance across the full load spectrum, as demanded by the wide load variation from extended hours at no load, to peak loading at 100% of capacity, typical on a daily basis.
The E-Saver SOL OPAL™ Series aligns with sustainable building designs such as LEED, Net Zero, and other buildings that emphasize building efficiency, the use of solar energy and sustainable procurement requirements. The E-Saver SOL OPAL™ series saves 25-40% less energy losses compared to a typical DOE 2016 compliant transformer.
The lockable hinged door and our patented 360º Rotatable IR Port™ options, both provide quicker maintenance access and reduce arc flash safety risks.

Heavy loads for extended hours. Process equipment, labs, broadcast, telecom, and some data centers
|35%||CU/AL, CU opt.||33%||K20|
Close to full continuous load. Labs, broadcast, telecom, and data centers, where overload capacity adds value, and energy rates and cooling costs are elevated
Solar Applications. Operating from full load for long hours to idling at night
|30%||CU/AL, CU opt.||20%||K20 but not required|
*Estimated average energy savings for each load profile vs. DOE 2016 minimum efficiency rated transformer
**CU=Copper, CU/AL=Copper Primary with Aluminum Secondary
***K-Rating per IEEE-C57.110. The high K-factor rating is not the goal of the design, but a consequence of the low current densities used to achieve the high loading efficiency goals.
