Designed for Stand-Alone Power Systems (SPS)
With decades of experience, SES offers split-phase transformers engineered for off-grid, battery-based, and hybrid renewable power systems, where a stable, dual-voltage output is required from a single energy source.
Commonly used in SPS, our transformers deliver a balanced energy supply and seamless integration with switchboards, loads, or inverter-based systems. We’ve supported hundreds of installations across the country, so you can trust that our team will deliver consistent quality.
Typical SPS Isolation Split Phase Design Range
- Voltage: 240V primary to 480V centre tapped secondary (240V 0 240V)
- Power Rating: 10kVA to 50kVA
- Cooling: Dry-type, ANAN
- Enclosures: Open (IP00), Ventilated (IP23), or Weatherproof (IP65)
Designed for High Efficiency & Minimal Losses
Every SES split-phase transformer is carefully engineered to offer:
Efficiency First
Optimised for low no-load losses, reducing parasitic drain on battery-based systems.
Core Quality
High-grade core steel minimises eddy current and hysteresis losses, optimising for longer system runtime.
Thermal Precision
Precision-wound enamelled copper windings to reduce I²R losses, offering less heat build-up.
Verified Results
Performance and losses are verified through routine factory testing to ensure better overall system performance.

Our transformers are designed with durability in mind. Transformers are designed, built and tested to perform continuously for at least 25 years under normal operation, but some customers have had SES transformers in operation for over 40 years.
In most cases, yes. At SES, we can tailor your power solutions to seamlessly integrate with your existing setup.
If you have any other questions, don’t hesitate to contact our experienced team today.
