Energy Storage Inverter Solutions

Bidirectional, high-efficiency power-conversion architectures for residential, commercial and industrial energy storage, integrating battery management, DC-link regulation, grid-tied inversion and comprehensive system protection.

Energy storage inverter application

Bidirectional conversion for reliable, grid-ready energy storage

Energy storage inverters transfer power between a battery system, a regulated DC link and the AC grid or local load. During charging, the converter controls battery current and voltage while maintaining grid-quality input behavior. During discharge, stored energy is boosted to the DC link and converted into synchronized AC power for self-consumption, backup operation or grid export. The architecture must coordinate battery limits, bidirectional DC/DC control, inverter modulation, islanding detection, thermal management and rapid fault protection across every operating mode.

About the solution

Coordinated battery, DC-link and grid conversion across charge and discharge modes

The energy storage inverter links the battery to a stable high-voltage DC bus through a bidirectional DC/DC stage and exchanges power with the AC grid or local loads through a bidirectional inverter bridge. The controller coordinates precharge, soft start, current references, battery limits, grid synchronization, islanding behavior, transfer logic, thermal derating and protection so the system can move safely between charging, self-consumption, backup and export operation.

Scalable for residential storage, commercial peak shaving and industrial backup systems

The same functional platform can support wall-mounted residential batteries, hybrid solar-storage inverters, commercial energy-storage cabinets, microgrids, telecom backup, EV-charging support and industrial peak-shaving systems. Battery voltage, DC-link level, semiconductor rating, switching frequency, cooling method, grid code and communication interface can be scaled to the required power and installation environment.

Semiconductor categories aligned with the battery, converter, inverter and protection paths

Battery contactor drivers and protection MOSFETs, high-current bidirectional DC/DC switches, isolated gate drivers, inverter MOSFETs or IGBTs, current- and voltage-sense devices, digital power controllers, grid-monitoring supervisors, auxiliary-power ICs and communication interfaces provide a practical component platform for efficient and robust energy storage inverter designs.
