Maximize Energy Harvest

Balance Solar Energy Harvest, Efficiency, and Power Density

Changing sunlight and operating conditions can make it challenging to maximize solar energy harvest while maintaining conversion efficiency, compact size, and power quality.

Renesas RA6T2 MCUs provide real-time control and high-resolution PWM, while GaN power devices and gate drivers support efficient switching in solar microinverters. MPPT control helps optimize energy harvesting, and high-frequency switching reduces magnetics size.

Improve Grid Visibility

Monitor Grid Conditions and Enable Remote Response

Distributed grid equipment can make it challenging to maintain accurate visibility of electrical conditions, identify abnormalities, and communicate operating status across energy networks.

Renesas precision-sensing MCUs provide high-resolution electrical measurements, while connected controllers support feeder monitoring and remote response. PLC modem ICs and line drivers support data exchange over existing power lines, helping to reduce the need for additional communication wiring. Together, these capabilities support timely fault reporting, remote diagnostics, and the coordinated monitoring and control of distributed grid equipment.
