2. Expansion Function
Theoretically, UPS parallel has no quantity limitation. However if the quantity is
over many, the reliability of the whole parallel system will decrease on the contrary,
and can not reach the aim of improving reliability. Therefore, we don’t suggest
using parallel mode to extend gross output power. In the application of UPS
parallel system, double machines parallel is frequently used.
