Why Choose the HT UPS Energy Storage Solution?
The HT UPS Energy Storage Solution uses a dual-PCS online architecture to provide uninterrupted power for critical loads without relying on STS switching.
0 ms Power Transfer
Unlike traditional STS solutions, which typically require 5–15 ms for source switching, the HT UPS keeps the load-side PCS continuously online. There is no switching action when the grid fails.
Dual-PCS Redundancy
Traditional STS systems rely on a single switching point. The HT UPS uses two PCS units to provide system-level redundancy and reduce single-point-of-failure risk.
True Online Double Conversion
Instead of relying on source switching to respond to grid disturbances, the HT UPS uses online double conversion to isolate critical loads and maintain stable output voltage and frequency.
Support for Demanding Loads
The PCS supports three-phase unbalanced and non-linear loads, making the solution suitable for data centers, precision manufacturing, healthcare, and other critical applications.
522 kWh Extended Backup
While conventional UPS configurations often provide minute-level backup, the integrated 522 kWh battery enables extended, hour-level power support during prolonged grid outages.
Traditional STS vs. HT UPS
Traditional STS solutions depend on switching between power sources, which can introduce a brief interruption and expose critical loads to switching disturbances. The HT UPS eliminates this switching process through its continuously online dual-PCS architecture.
Traditional STS solutions also have a critical dependency on the switching device itself. With dual PCS redundancy, the HT UPS reduces this single-point-of-failure risk while providing integrated power conversion and extended battery backup.

FREQUENTLY ASKED QUESTIONS
Under the standard configuration, the Energy Storage Container occupies less than 6.5m² — roughly the size of a standard parking space. Installation only requires a hardened, level concrete ground surface; no dedicated equipment room is needed. Upon delivery, the unit is craned into place, connected to the AC input cable and grounding, and it is ready to use.
Charging: At the rated input of 125kW, it takes approximately 4.2 hours to fully charge .
Discharging: At the peak output of 250kW, it takes approximately 2.1 hours to fully discharge.
The system supports customizable charge/discharge management based on time, power level, or strategy, and can also operate automatically according to peak/off-peak electricity tariff periods.
A liquid cooling system maintains the temperature difference between cells within ≤2°C, whereas air cooling typically results in a difference of 5–8°C. A smaller temperature difference means:
Better cell consistency and slower degradation
Approximately 20% longer cycle life
Stable full-power operation even in high-temperature environments
Lower system noise (no high-power fans)
VSG (Virtual Synchronous Generator) allows the energy storage equipment to actively support the grid just like a conventional generator:
Grid-connected mode: Automatically participates in frequency/voltage regulation, reducing impact on the grid.
Off-grid mode: Multiple units can automatically form a grid and independently operate loads.
Practical benefits: Prevents frequent disconnection in weak grid areas, and avoids "charging interruptions" at PV-storage-charging stations.
Maintenance is very simple:
Liquid cooling system: Check the coolant level every 6–12 months.
Electrical connections: Tighten power cables once per year.
Software updates: Completed remotely via OTA.
