Monitor battery cells and manage stored energy with our multi-cell battery-management ICs, precision power monitors, and RA MCUs. Deliver scalable battery packs with daisy-chain monitoring, real-time power alerts, and intelligent system control for reliable energy-storage operation.
Connect smart meters and grid devices using our PLC modem ICs, line drivers, and RX MCUs. Support G3-PLC and PRIME communication over existing power lines, with reliable data exchange and network management for connected energy infrastructure.
Monitor grid conditions and respond to abnormal power flow with our precision-sensing MCUs, connected controllers, and power ICs. Combine integrated 24-bit ADC measurement, remote monitoring, and bidirectional power control to support responsive feeder automation and dependable grid operation.
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.
Integrating solar generation, battery storage, and grid connectivity requires the precise control of multiple power paths as generation and demand change.
Renesas real-time MCUs, GaN power devices, and gate drivers combine digital control with high-frequency switching to support solar MPPT, bidirectional battery charging and discharging, and on-grid/off-grid operation. Together, these devices enable coordinated power conversion across generation, storage, and loads while supporting compact, efficient hybrid inverter designs.
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.
Accelerate solar battery charging designs with a buck-boost power solution that features maximum power point tracking (MPPT), programmable charging, and integrated protection for efficient lead-acid battery charging across changing solar conditions.
