No additional shunt bar required for under 50 amps. Monitor amperage from batteries, wind turbines, solar panels, inverters, generators, hydroelectric, and more.
Tips & Things to Remember in DC Amp Meter Wiring:
Use a DC amp meter for amp readings
Don't allow incoming power to exceed the rated amperage (or voltage) of your meter - it may break the unit
Match the amp rating of the meter to the amp rating of the shunt bar
Match the millivolts (mv) of the meter to the millivolt (mv) rating of the shunt bar
The two wires between the meter and shunt bar need to be the same length
A wind turbine should be connected to a separate meter than the solar panel(s)
To test the amps or volts of your wind turbine or solar panel system with a handheld clamp on meter, you must use a DC model
Troubleshooting your DC Meter Issues:
If the needle on the meter is a negative reading, switch the sense wires between the meter and shunt bar
If the needle on your analog meter is not at zero when there isn't incoming power, you can calibrate it by turning the screw on the front of the meter
If your digital handheld DC meter isn't giving you an accurate reading, check the batteries in the unit
About DC Volt Meters:
The positive and negative inputs are typically not marked on the DC Volt Meter. If you connect them to your battery and get a negative reading, simply swap the wires.
12 Volt battery systems should use a 15 Volt meter; 48 Volt systems should use a 70-75 Volt meter.
