RAY-MAX - Transformer Complements
The RAY-MAX Transformer complements the Nextronex RAY-MAX System* by providing the required galvanic isolation and AC interconnect voltage, while maintaining best-in-class efficiency. This is a logical choice for stand alone inverter installations, or small distributed systems where the interconnect voltage is less than 600 V. A thermal switch is incorporated in the transformer core that can be interfaced to our Smart Controller to protect against damage or overload.

The transformerless RAY-MAX® Inverter has an AC output voltage proportional to the DC string voltage. To maximize the power output, the RAY-MAX® Transformer is wound to allow the inverter to operate at the most efficient output voltage, while coupling it to a standard AC interconnect voltage, typically 208, 240, 277, 380, or 480 V, all with multiple taps for optimal matching. The power rating of the transformer is nominally 100 kVA for 600 V systems, and 165 kVA for 1000 V systems.
