Renogy Battery Shunt 300 System Setup

You can connect the Battery Shunt 300 to a starter battery via the B2 port on demand.

Required Tools & Accessories

Prior to installing and configuring the shunt, prepare the recommended tools, components, and accessories.
For how to size bare wires, refer to “How to Size Bare Wires?” in this manual.
For the connection methods and required tools for the main battery, starter battery, and equipment terminal, please refer to the corresponding device user manual. The diagrams provided within this manual are for illustrative purposes only.
For how to use Wire stripper, Heat Shrink Tubing, Manual Hydraulic Pliers, and Heat Gun to install 3/8 in Lugs (M10 Ring Terminals), visit renogy.com/support/downloads to check Battery Shunt User Manual.

How to Size Bare Wires?

Select proper bare wires based on the ampacity in your power system. Refer to the table below for copper cable ampacities with different gauge sizes.

The above values are from the NEC Table 310.17 for copper cables rated at 194°F (90°C), operating at an ambient temperature of no more than 86°F (30°C). Cables longer than 13 feet (4000 mm) may require thicker gauge wires to prevent excessive voltage drop in undersized wiring.

Check System Voltage and Current

Ensure the battery shunt operates within a power system with a maximum system voltage of 120V and a continuous current of up to 300A. Exceeding these voltage and current limits may cause damage to the shunt.
Risk of electric shock! Before installing the shunt, please turn off all devices within the system and ensure there is no current flowing through the circuit.
Step 1. Plan a Mounting Site
Select a proper mounting site to ensure the shunt can be safely connected to the battery and other necessary devices with the relevant cables. Install the shunt in a clean, cool, and dry location, free from any accumulation of water, oil, or dirt. For optimal Bluetooth communication, avoid placing the battery shunt near metal objects.

Step 2. Wear Insulating Gloves

Step 3. Remove the Covers
█ Remove the Upper Cover

█ Remove the Lower Cover

Step 4. Connect the Shunt to the Main Battery Negative

You can connect a main battery to the B- terminal because connecting other devices to this terminal may affect the shunt’s accuracy in current detection.
For how to connect batteries in series or parallel to the battery shunt, refer to the Battery Shunt User Manual by scanning the QR code in the preface of the guide or at www.renogy.com/support/downloads.

Step 5. Connect the Shunt to the Device BAT-

Step 6. Connect the Shunt to the Main Battery Positive

Step 7. Connect the Shunt to the Starter Battery Positive (Optional)

Step 8. Install a Battery Temperature Sensor
The temperature sensor measures the temperature of the main battery and sends the temperature value to the DC Home app. The app displays a low/high temperature alarm when the battery temperature reaches a preset limit.

Step 9. Mount the Shunt (Optional)
You have the flexibility to select a suitable mounting method based on your preference. You can opt to mount it on a wall, the floor, or even use a floating installation approach.

Step 10. Install the Covers
█ Install the Lower Cover

█ Install the Upper Cover (Optional)

Installing the Upper Cover is optional in cases where the terminals are not enclosed by the cover.

Step 11. Power On
Power on all devices in your power system, and the Battery Shunt is powered up automatically with the Power LED Indicator lighting up.
If the Power LED Indicator fails to illuminate, please inspect the cables for any signs of short circuits or loose connections. If the issue persists, please reach out to our technical support team via renogy.com/contact- us.

LED Indicators

Bluetooth Pairing

To ensure optimal system performance, keep the phone or RENOGY ONE Core within 10 feet (3 m) of the shunt.
█ Initial Pairing:

1. Open the app or RENOGY ONE Core.
2. Search and pair the Battery Shunt.

█ Pairing with Other Devices:

1. Remove the shunt from the DC Home app or ONE. Alternatively, you can press and hold RESET on the shunt for 5s.
2. The Bluetooth LED turns off. Re-scan and pair the shunt with other devices.

Energy Monitoring

Depending on the specific application, the shunt can establish either short- range or long-range communication connections with monitoring devices. These monitoring devices including RENOGY ONE Core and DC Home facilitate real-time monitoring, programming, and complete system management, offering comprehensive control and enhanced flexibility.
The version of the DC Home app might have been updated. Illustrations in the user manual are for reference only. Follow the instructions based on the current app version.
Download and login to the DC Home app.

█ Short-Range Monitoring via DC Home App
For initial use, set the “Rated Battery Ah” (rated battery capacity) on the app prior to other operations.

█ Wireless Long-Range Monitoring
If long-range communication and programming are required, connect the shunt to RENOGY ONE Core (sold separately) through Bluetooth, and the RENOGY ONE Core to the DC Home app through Wi-Fi.
Recommended Components

*RENOGY ONE Core

Components marked with “*” are available on renogy.com.
For instructions on Renogy ONE Core, see Renogy ONE Core User Manual.
Make sure the shunt does not communicate with any other device.

Troubleshooting

Important Safety Instructions

█ General

• Wear proper protective equipment and use insulated tools during installation and operation. Do not wear jewelry or other metal objects when working on or around the shunt.
• Keep the shunt out of the reach of children.
• Do not dispose of the shunt as household waste. Comply with local, state, and federal laws and regulations and use recycling channels as required.
• In case of fire, put out the fire with a FM-200 or CO₂ fire extinguisher.
• Do not expose the shunt to flammable or harsh chemicals or vapors.
• Clean the shunt regularly.
• It is recommended that no cables should exceed 10 meters because excessively long cables result in a voltage drop.
• The cable specifications listed in the user manual account for critical, less than 3% voltage drop and may not account for all configurations.
• Do not expose the shunt to strong electrostatic fields, strong magnetic fields, or radiation.

█ Shunt Safety

• Please keep the shunt away from water, heat sources, sparks, and hazardous chemicals.
• Do not puncture, drop, crush, burn, penetrate, shake, strike, or step on the shunt.
• Do not open, dismantle, repair, tamper with, or modify the shunt.
• Do not touch any terminals or connectors.
• Please make sure all devices have been disconnected before working on the shunt.
• Do not insert foreign objects into the terminals of the shunt.
• You can connect a main battery to the B- terminal because connecting other devices to this terminal may affect the shunt’s accuracy in current detection.
