UPS / Microgrid Systems TGH33 Series 150–250kW PV-ESS All-in-One Microgrid UPS System
Energy storage product for B2B applications
View Details →
Advanced energy storage product engineered for reliable power applications, scalable supply, and global B2B project requirements.
The integrated Battery Management System continuously monitors charging and discharging conditions to help protect the battery from overcharge, over-discharge, overcurrent, and other electrical risks. This intelligent protection supports safer operation, stable performance, and longer battery service life.

Designed for residential energy needs, the system can provide stable power support for common household appliances such as refrigerators, televisions, washing machines, fans, lighting, computers, and kitchen equipment. It helps improve home energy flexibility for daily use, solar self-consumption, and backup power applications.

Equipped with multiple DC output interfaces, the system can power or charge several devices at the same time. It supports flexible connections for laptops, routers, lighting, fans, cameras, mobile devices, and other compatible DC equipment, providing convenient power distribution for residential and backup energy applications.

The integrated design combines the inverter, MPPT solar charge controller, and lithium battery into one compact system. This streamlined architecture reduces external components and wiring, simplifies installation, and provides efficient solar energy conversion, storage, and power management for residential and backup power applications.
