Solar-Storage Microgrid

A DC-coupled PV and battery architecture can form the core of a larger three-phase solar-storage system. Match the PV configuration, battery voltage, and load profile to the selected TGH150 or TGH250 model.

Industrial Peak Shaving

Choose load-priority, battery-priority, or peak-valley mode to coordinate battery dispatch with factory demand. Match battery and inverter capacity to the facility's operating schedule and peak load.

Weak-Grid Site Resilience

The listed 320–460 Vac input range and high load-impact capability support projects in areas with unstable utility supply. Pair the system with a properly sized battery and configure protection and transfer behavior for the site loads.

Critical Facility Backup

For high-priority commercial or infrastructure loads, the TGH150/TGH250 platform offers 150/250 kW rated power, configurable battery control, and a listed 0 ms inverter-to-bypass and bypass-to-inverter transition. Confirm backup boundaries and redundancy requirements during project design.
