Franklin Home Power Solution
Backup Reserve allows you to determine how much of your aPower batteries stored energy will automatically be saved as backup power. With the ability to adjust your aPower battery state of charge (SOC) threshold in the app, you can control the level of energy security that your aPower batteries provide during a grid outage.
How It Works
Your Backup Reserve represents a portion of an aPower's stored energy. The remaining portion is allocated to Self-Consumption mode or Time of Use mode. During an outage, your Backup Reserve becomes available and the aPower begins to discharging to power your home. Depending on the duration of the outage, your aPower may discharge below your set reserve percentage. When the outage is resolved, your aPower will prioritize charging above your reserve percentage before resuming normal operation.
How to Set Up
To set up a backup reserve in Self-Consumption mode, open the FranklinWH App and follow these steps:
-
On your energy home screen, tap Settings.
- Enter Mode, select Self-Consumption.
-
Set your preferred Reserved energy for outage by adjusting the slider at the top of the screen.
Note: If the aPower battery available SOC is set to 100%, effectively Emergency Backup mode, the FranklinWH system will charge to full power (aPower battery actual SOC value = 100%) from solar and then not discharge from the batteries. In the event of a grid failure, the system will power the household loads. If the Reserve SOC is set to 100%, Self-Consumption or Time of Use modes cannot be used. This will negatively impact the potential economic benefits of those modes and increase your reliance on the grid.
If you prefer to reserve more energy for use during a grid outage or if your area is more prone to outages, you can set a higher reserve percentage. If you prefer to optimize your aPower's performance in Self-Consumption mode or Time of Use mode, you can set a lower reserve percentage.
If you set the Reserve SOC value to below 20%, a prompt will be displayed "If the Reserve SOC is too low, your aPower may not have enough stored energy to provide backup support in the event of an outage".
