5.4. SOC Synchronization

To ensure reliable readout of the SOC of your battery, SOC synchronization is required, especially for batteries that have been used for an extended period. A battery's capacity can degrade over time, so even if the battery may charge to full capacity, its actual capacity might not be as high as when it was new. For instance, a new battery rated at a full capacity of 100Ah can only charges to 90Ah after a year of use. In this case, recalibrating the SOC is required, using 90Ah as the new reference point, rather than the original 100Ah.

SOC synchronization should be performed in the following scenarios:

• During the initial shunt installation
• After there has been an interruption in the voltage supply to the DC Home or Renogy ONE
• When the battery has not been fully charged
• When the DC Home or Renogy ONE has not detected that the battery has been fully charged because the "Charging Amps" has been set incorrectly.

In this case, review the settings and make sure the battery regularly receives a full charge.

DC Home app

In the DC Home app, follow the steps below to synchronize the battery SOC in your system:

Step 1: Tap the shunt details page. Tap "... > Settings" in the upper-right corner of the page.

Diagram Description: Screenshots of the DC Home app showing the shunt details page and navigating to Settings.

Step 2: Under "Battery", tap Sync in "SOC sync".

Diagram Description: Screenshots of the DC Home app showing the Battery settings and the SOC sync option.

Step 3: You can choose "Sync to 100%", "Sync to 0%”, “Customization" or "Cancel". It is recommended that you customize the SOC to match the actual SOC of your battery. Allowed value ranges from 0 to 100.

Diagram Description: Screenshots of the DC Home app showing the SOC synchronization options.

Renogy ONE

In Renogy ONE, follow the steps below to synchronize the battery SOC in your system:

Step 1: Tap the shunt details page. Tap "..." in the upper-right corner of the page.

Diagram Description: Screenshots of the Renogy ONE app showing the shunt details page and navigating to Settings.

Step 2: Under "Battery", tap Sync in "SOC sync".

Diagram Description: Screenshots of the Renogy ONE app showing the Battery settings and the SOC sync option.

Step 3: You can choose "Sync to 100%", "Sync to 0%”, “Customization" or "Cancel". It is recommended that you customize the SOC to match the actual SOC of your battery. Allowed value ranges from 0 to 100.

Diagram Description: Screenshots of the Renogy ONE app showing the SOC synchronization options.

Step 4: Tap "Sync" to complete the synchronization.

Diagram Description: A screenshot showing "SOC Sync Successfully!".

ℹ️ The version of the DC Home app and Renogy ONE might have been updated. Illustrations in the user manual are for reference only. Follow the instructions based on the current app version.

5.5. Essential Alarm Settings

The battery shunt provides diverse alarms to protect your battery from high temperature or voltage. Most settings can stay their factory default, but you can customize them to better serve your needs. On DC Home app or Renogy ONE Core, go to "... > Settings > Alarm" to configure essential alarms listed in the table below.

Diagram Description: Screenshots showing the navigation path to Alarm Settings in the DC Home/Renogy ONE apps.

ℹ️ The value ranges listed in the DC Home app or Renogy ONE Core prevail.

Diagram Description: Screenshots showing alarm settings and buzzer options in the DC Home/Renogy ONE apps.

5.6. Historical Data

You can access the historical data of the connected battery via DC Home app or Renogy ONE Core.

Diagram Description: Screenshots of the DC Home/Renogy ONE apps displaying historical data, including battery voltage, current, temperature, and charge/discharge values.

The following two parameters should be explained:

• Last Discharged Ah: This value represents the amount of electrical charge (in ampere-hours) that was consumed or discharged from the battery in the last discharge cycle. It is calculated by multiplying the discharge current (in amperes) by the duration of the discharge (in hours).
• Last Charged Ah: This value represents the amount of electrical charge (in ampere-hours) that was added or charged into the battery during the last charging cycle. It is calculated by multiplying the charge current (in amperes) by the duration of the charge (in hours).

ℹ️ Maintaining historical data is essential for diagnosing potential battery issues. Avoid clearing the history unless replacing the battery to preserve valuable information about its performance and behavior over time.

5.7. Device Info

In "... > Settings", navigate to "General" where you can:

• Change the display name of your battery shunt
• Access the SN of your battery shunt
