be used to bring the inverter out of its search mode, or the inverter may be programmed to remain at full
output voltage.
2.5.6 Protections
The TPH series inverter is equipped with extensive protections against various harsh situations/faults.
These protections include:
AC Input over voltage protection/AC Input low voltage protection
Low battery alarm/High battery alarm
Over temperature protection/Over load protection
Short Circuit protection (1sec after fault)
Back feeding protection
When Over temperature /Over load occur, after the fault is cleared, the master switch has to be reset to
restart the inverter.
The Low batter voltage trip point can be customized from defaulted value 10VDC to 10.5VDC turn the SW1
on DIP switch.
The inverter will go to Over temp protection when heat sink temp. ≥105ºC, and go to Fault (shutdown
Output) after 30 seconds. The switch has to be reset to activate the inverter.
The TPH series Inverter has back feeding protection which avoids presenting an AC voltage on the AC input
terminal in Invert mode.
After the reason for fault is cleared, the inverter has to be reset to start working.
2.5.7 Remote control Module
Apart from the switch panel on the front of the inverter, an extra switch panel connected to the RJ11 port at
the DC side of the inverter thru a standard telephone cable can also control the operation of the inverter.
If an extra switch panel is connected to the inverter via “remote control port”, together with the panel on the
inverter case, the two panels will be connected and operated in parallel.
Whichever first switches from “Off” to “Power saver off” or “Power saver on”, it will power the inverter on.
If the commands from the two panels conflict, the inverter will accept command according to the following
priority:
Power saver on> Power saver off> Power off
Only when both panels are turned to “Unit Off” position will the inverter be powered off.
The Max length of the cable is 10 meters.
