PS1 Sinewave Interactive Inverter Charger
Shunt Settings
The inverter provides two shunt inputs for monitoring of DC currents. These shunts can be used for
renewable or load shunts.

This group of menus defines the type of shunts
connected to the inverter and whether the current
measured through each shunt id interpreted as a
load on the battery or a renewable source charging
the battery.
Shunt 1 Renewable: Options ON, OFF
If configured for ON the current measured on this
shunt will be considered as charging the battery.
Shunt 1 DC Load: Options ON, OFF
If configured for ON the current measured on this
shunt will be considered as a DC load on the battery.
Note If both of the above options are selected for
Shunt 1 the net current will be displayed.

Shunt 1 A/mV: Shunt 1 Amperes per millivolt
defines the type of shunt connected to Shunt 1 input.
It allows the inverter to interpret the measured
millivolts in terms of Amperes. The number to be
entered is calculated by dividing the shunt rated
current by the rated voltage
eg a 75mV/100A shunt = 100 ÷ 75 = 1.33A/mV
Shunt 1 Zero: Calibrates shunt 1.Recommended
calibration procedure:
Set Shunt 1 A/mV to 1.0
Set Renewable and DC load ON.
Read Shunt 1 Amps from the View Readings
menu.
Adjust Shunt 1 Zero to the negative of reading
value. (eg read +1.5 enter -1.5, read -2.5 enter
+2.5).
Set Shunt 1 A/mV as per the table above.
Set Renewable and DC load setting as required.
The table below list some common shunt types and
the associated setting:
Shunt
Setting
50mV/100A 2.0
75mV/100A 1.3
75mV/200A 0.6
50mV/50A
1.0
Shunt 2: All of the above information also relates to
Shunt 2.
