It is primarily used in distributed‑power supply applications on production lines, as well as in centralized power‑supply systems such as DCS control systems, communication systems, monitoring systems, and network management centers—critical equipment and environments that require highly reliable, uninterrupted power.
01.
More power generation
Lower start-up voltage, more efficient solar energy utilization, and effectively increased power generation.
Supports multi-winding transformers, reducing transformer investment by 5–10% compared to double-split transformers.
02.
Higher reliability
With 20 years of industrial‑grade UPS product expertise in the power sector, we serve major state‑owned enterprises such as China Power and China Nuclear Power, and have developed inverter products on a unified platform.
Exclusively equipped with industrial air-conditioning units, ensuring that the equipment does not operate at a derated capacity when the ambient temperature exceeds 40°C.
03.
Higher intelligence
Color LCD large touchscreen, with comprehensive local configuration and management support, enabling continuous active power adjustment from 0 to 100% and reactive power compensation for grid operation.
04.
Greater adaptability
Low-voltage ride-through capability; strong grid adaptability.
Modular design, easy to install and maintain;
Compact size (two cabinets), saving installation space.
05.
Higher inverter efficiency
A master–slave inverter system consists of several parallel inverter modules that share a common DC input. Under partial‑load conditions (non‑full‑load operation), the system can keep the slave modules in standby, ensuring that the master module operates within its optimal efficiency range.
06.
Higher fault tolerance
In the USG modular system, only the faulty module ceases power generation, while the remaining modules continue to operate. This minimizes the impact of failures to the greatest extent.
07.
Longer life expectancy
Because inverters in a master–slave configuration do not continuously utilize all inverter modules, but instead operate in a manner that optimizes maximum power point tracking, they exemplify a more robust system: requiring lower maintenance costs while delivering a longer expected service life.
