Application diagram

High-voltage stacked ESS system architecture

The stacked high-voltage series is intended for projects using higher DC bus voltage, where modular battery towers feed compatible PCS or high-voltage inverter systems.

Step 1

PV or power conversion source

Energy enters the storage system through a high-voltage inverter or PCS architecture.

Step 2

HV inverter / PCS

Controls battery charging, discharge dispatch, and AC-side conversion for the project load.

Step 3

TB-G stacked HV battery

Modular high-voltage LiFePO4 stack supplies the required DC bus voltage with serviceable tower construction.

Step 4

Protection and switchgear

Project-side safety equipment coordinates isolation, protection, and operational control.

Step 5

Commercial load or distribution

Stored energy is delivered to the downstream system for project or commercial usage.

Step 6

System monitoring

Battery and inverter communication supports condition monitoring and fault management.

High-voltage system matching should be confirmed against inverter voltage window, protection design, and installation standards.

Parallel expansion

Modular high-voltage capacity scaling

The TB-G stacked platform increases system energy by raising module count and working voltage inside one family, helping projects scale without changing the overall product logic.

Five capacity steps cover 10.24kWh to 30.72kWh in one modular HV range
Rated voltage expands from 204.8V to 614.4V for broader inverter matching
Stacked architecture supports modular service and phased capacity planning for project sites
