TJ10-G/TJ30-G Monitor and STS module

single phase                      230Vac output             6KVA – 20KVA

three phase                       230Vac output             6KVA – 48KVA


This module is being composed by a central monitor and static transfer switch, which can be used for HTM250 system.



  • Display: it allows the user to monitor the system status in real time and read all parameters including voltage, current, frequency, capacity and failure info etc.
  • System setting : protection level and time
  • History record : can record max 100 records
  • Communication: RS485 for PC software monitoring and relay dry contact.
  • Auxiliary contacts


Static transfer switch (STS)

It increased the system availability by automatic transfer between the inverter and AC main. By setting up the priority of operation mode, user can change the systems status of “on line mode” or “standby mode”
