DAELIM Transformers for application in Distributed Photovoltaic (DPV) Power Generation Systems,aka, Solar Energy. In DPV Power Generation Systems electrical power is generated by converting solar radiation into direct current (DC) electricity using semiconductors that exhibit photovoltaic (PV) effect. Photovoltaic power generation employs solar panels comprising a string of photovoltaic modules (cells) containing a photovoltaic material, often made of silicon. The PV module can typically generate a combined dc voltage of up to 1100V (DC).
The generated DC voltage is then converted to a three-phase AC voltage using a three-phase inverter. The inverter is subsequently connected to a DPV system inverter transformer for distribution of alternating current (AC) energy. From residential rooftops to commercial and industrial applications and utility-grade power plants, DAELIM’s fit-for-purpose solar distribution transformers are speifically matched to different solar inverter sizes and their applications.
1. FR3 dielectric fluid provides fire safety, equipment reliability and a projected lifespan well beyond that of a traditional mineral-oil transformer making it a key component in balance of system (BOS) distributed energy resources (DER) solutions
2. Custom optimized transformer designs for specific loading profiles, impedance requirements, and single or multiple inverter connections
3. Increased overload capability above nameplate without loss of insulation life
4. Fully complements solar/energy balance of system (BOS) solutions including DC and AC combiners, disconnects, fuses, breakers and AC recombiners, padmounted switchgear, pole-mounted reclosers, air switches, capacitors and a full offering of services
1. Rated output kVA:
• Based on inverter output ratings, load diagram, harmonic content, weather patterns and unusual service conditions
2. Nominal Voltage:
• Designed for Inverter Transformer to be compatible with Pulse voltage shape of inverters
3. Winding connection diagram and vector group:
• Inverter operation is not affected by vector group like Dy1, Dy5 or Dy11
• No Neutral required on Primary LV side
• Isolated neutral point on Secondary HV side transformer
4. Electrostatic Shield (ES):
• Recommended installation of ES between primary and secondary windings to minimize potential transfer of high frequency voltage disturbances (harmonics, pulses, surges) from primary to secondary
• Windings typically connected to inverter circuits are ungrounded
