Renewable Energy Power Solutions

For solar inverter control systems, we recommend the LM series AC/DC power supplies (LM150-23B24, LM200-23B24) for main control power. These provide 24V at 150W-200W with high efficiency up to 92%, wide temperature range, and comprehensive protection. For auxiliary power, the URB series DC/DC converters can generate isolated voltages for communication interfaces and sensors.

Choose LM series for main control power based on total system power requirements. Add DC/DC converters for isolated auxiliary voltages.

For SiC MOSFETs in solar inverters, use the QA-R series gate driver supplies. Key considerations: Isolation voltage - 6000V for high-voltage systems (800V+ DC bus). CMTI rating - 100kV/us for SiC high dv/dt switching. Output voltage - +15V/-4V optimized for SiC threshold voltages. Isolation capacitance - 10pF typical to minimize common-mode current. The QA-R4G0315T or QA-R3G0315T are ideal for SiC applications.

Use QA-R series for SiC MOSFETs. Ensure isolation voltage exceeds DC bus voltage. Verify CMTI rating for switching frequency.

For outdoor solar installations, select products with -40°C to +85°C or wider temperature range. Recommended products: Gate driver supplies (QA series): -40°C to +105°C. AC/DC supplies (LM series): -30°C to +70°C. DC/DC converters (URB series): -40°C to +85°C. Consider derating at temperature extremes and ensure adequate airflow or heat sinking for enclosed installations.

Select products rated for full outdoor temperature range. Consider derating and thermal management for reliable operation.

Yes, Mornsun power supplies are well-suited for energy storage systems including battery management systems (BMS) and power conversion systems (PCS). The wide input voltage range handles varying battery voltages. High isolation ensures safety in high-voltage battery systems. Wide temperature range accommodates battery enclosure environments. Products like the URB series DC/DC converters are ideal for generating isolated voltages for BMS electronics.

Use isolated DC/DC converters for BMS electronics. Select AC/DC supplies for grid-side control systems. Ensure isolation rating meets safety requirements.

Renewable energy applications typically require: Safety certifications - UL 1741 for grid-tied inverters, IEC 62109 for PV systems, UL 1973 for energy storage. EMC compliance - EN 55032 for conducted and radiated emissions, IEC 61000-6-2 for immunity. Environmental - IP ratings for outdoor enclosures, temperature cycling.
