1.2 Product Overview
The STS (Static Transfer Switch) module increases system reliability by automatically switching between the
inverter output and the AC mains. By setting up the priority of operation mode, users can change the system
status of “on line mode” or “off line mode”. The on line mode will keep the input power provided by inverter line
and when inverter fails, the line will switch to AC utility line. In off line mode, the system power is always
connected to the AC utility line and will switch to inverter power line when AC utility fails. The transfer time is less
than 1/4 cycle which can avoid the power interruption. The reliable performance of the STS module can provide
the maximum protection to the connected telecommunication equipment against possible damage caused by the
system power failure.
