Inspect for reverse contact on B- or Pterminals.

Confirm the Battery Temperature Sensor is properly installed.

The battery capacity decreases as the charging and discharging cycles increase.Re-configure the “Rated Battery Ah” to the capacity when the battery is fully charged.

Elevated ambient temperatures can affect sampling accuracy. Ensure proper ventilation for the shunt and remove the upper cover if needed.

If you notice that your Battery Shunt 300 displays only discharging readings after installation, with the readings staying at zero, please follow these steps: 1.Remove Battery Shunt from both Renogy One Core and DC Home. 2. Uninstall the DC Home app and install a new DC Home app. 3. To avoid potential conflicts, turn off your phone before proceeding. 4.Set Renogy One Core to pairing mode and reset the Battery Shunt. 5.Pair Renogy One Core and Battery Shunt 300, then turn on your phone. 6.Activate pairing in DC Home; you will see a link, not the Battery Shunt 300 readings. However, this link is pairing Battery Shunt 300 and Renogy One Core with DC Home. 7. Pair this link. By following these steps,you can resolve the issue, and the Battery Shunt 300 readings displayed correctly. If the issue persists, it's recommended to contact Renogy's technical support for further assistance.

Battery Shunt 300 does not differentiate between battery types. Its calculations are based on current and voltage. During the initial connection, it will prompt you to input the battery capacity. It can also be manually calibrated. After fully charging the battery, set the current SOC to 100% in the settings.While specific programming for different battery types isn't available, these settings and manual adjustments ensure precise monitoring and control.

The 300A specification of the Battery Shunt represents its maximum capacity rather than indicating a limitation based on battery bank size. It is not restricted to use only with 300A battery banks. To ensure compatibility, calculate the actual maximum continuous current in your circuit, and the Battery Shunt 300 should be suitable for monitoring larger battery banks.
