PQ curves
By default, the PCS operates in active power priority. When required, it can operate on reactive power mode with two options:
Working mode 1:
In this mode, PCS operates in reactive priority mode by default; When scheduling according to "controlled direct reactive power regulation", the maximum reactive power capacity is S=220kVA. After responding to the reactive power Q kVar capacity, the remaining capacity P kW capacity is then used to respond to the active power
Working mode 2:
In this mode PCS operates in reactive priority mode by default; When conducting constant power factor scheduling according to the "controlled power factor adjustment", it has the following table characteristics.

Derating with bus voltage
The battery voltage range that supports the PCS operating at rated power is 1,000– 1,400 Vdc.
The battery voltage range of the 20C2H1600K is 1,075.2–1,363.2 Vdc (cell voltage: 2.8–3.55 Vdc) within this range. The PCS operate at 80% of the rated apparent power at 1500Vdc. If the battery voltage drops below 1,000 Vdc or rises above 1,500 Vdc, the PCS will not operate. The calculation is determined by internal software and hardware design of the R&D department,
and complies with IEC 62477-1 (LVD) and IEC 61000-6-2_6-4 (EMC)
Derating with altitude
The PCS is capable of operating at 110% of the rated apparent power at altitudes from 0 to
3000m, 100% of the rated apparent power at 4000m.
The calculation is determined by internal software and hardware design of the R&D department, and complies with IEC 62477-1 (LVD) and IEC 61000-6-2_6-4 (EMC).
Derating with temperature
The PCS is capable of operating at 110% of the rated apparent power at-30℃-35℃,
100% of the rated apparent power at 45℃.
The calculation is determined by internal software and hardware design of the R&D department,
and complies with IEC 62477-1 (LVD) and IEC 61000-6-2_6-4 (EMC)
