The Go Power! PowerTrak Smart Shunt (GP-SHUNT-500) measures current at the battery negative and sends state of charge, current, remaining amp-hours and time to empty to your PowerTrak display over the RV-C network. It's rated for 275 amps continuous and 500 amps surge. The 500 amp figure in its model number is the surge rating.
Because it measures current at the battery negative, it works with AGM, flooded, gel and any brand of lithium battery. It needs a PowerTrak display, since the shunt has no screen or app of its own. Go Power! Advanced Lithium batteries don't need it, because they report to the display directly over RV-C.
The shunt counts the current flowing in and out of your bank, so the PowerTrak display can show state of charge, current, remaining amp-hours and time to empty for AGM, flooded, gel or LiFePO4 batteries from any brand.
Go Power says the 275 amp continuous rating covers a 2000 watt inverter on a 12 volt system with margin. The surge rating is 500 amps.
Go Power says the shunt provides both data and power to the RV-C network. Its battery readings appear on the same PowerTrak screen as your RV-C solar controller and inverter charger.
The 7.5 to 58 volt supply range covers 12, 24 and 48 volt systems. Maximum supply current is 25 mA at 12 volts, or 150 mA with a disconnect relay connected, and under 20 mA at 24 volts.
Two posts are marked B- for the battery negative and L- for the loads, and an LED indicator light sits on the housing. The shunt also has a connection for an optional relay.
Lead-acid banks. Add state of charge for AGM, flooded or gel batteries to a PowerTrak system.
Other lithium brands. Monitor lithium batteries that can't report to PowerTrak on their own.
Inverter systems. Track a bank that feeds an inverter of up to 2000 watts at 12 volts, the example Go Power gives.
The shunt alone suits an RV that already has a PowerTrak display. If you don't have one yet, the Battery Manager Kit (GP-BMG) includes this shunt with the touchscreen display, a 25 ft harness and a terminating resistor.
Go Power! Advanced Lithium batteries send state of charge to the display over RV-C, so they don't need a shunt. Every other battery type needs the shunt for the display to show state of charge.
Mount the shunt as close to the battery as possible. Disconnect all wires from the battery negative first. Connect the B- terminal to the battery negative and the L- terminal to the negative side of your loads and charge sources. Nothing else can connect to the battery negative, or the readings won't be accurate. A shunt power harness runs to the battery positive, and RV-C harnesses connect the shunt to the display. Go Power lists a 17 mm (11/16 in) wrench, two ring terminals sized for your battery cable and a crimp tool.
No. It has no screen or app of its own. If you don't have a PowerTrak display, look at the Battery Manager Kit.
No. The shunt is RV-C only and pairs with the PowerTrak display.
No. Advanced Lithium batteries report state of charge to the display directly over RV-C.
Go Power gives the smart shunt a 2-year limited warranty.
The Go Power! PowerTrak Smart Shunt brings state of charge, current and time to empty for AGM, flooded, gel or lithium banks onto your PowerTrak display, with a 275 amp continuous rating. If you'd like help confirming the cables and display your system needs, the Outbound Power team is happy to help.
