DC SHUNT FOR ANALOG AMMETERS
Install shunt for analog DC current measurement:
Anexternalshuntissuppliedwith360panelsthatincludeaDCanalog
ammeter. Install the shunt at any point in the DC positive or negative, prefer-
ably in the most direct high current path (do not reroute the direct current
path to accommodated shunt placement). Mount shunt close to the panel
to keep the sense wires that run from the shunt to the meter short. Short
sense wires minimize voltage loss and result in the most accurate metering.
Mounting the shunt close to the battery bank may make it easier to include
morecircuits,suchas24-hourcircuits,inthemetering.Wirerunsupto50

Notes:

interference by twisting the sense wires together.
2. If the shunt is installed in the negative feed line, no fuses are required.
