SOC FAQ - Stage Zero



SOC is a measurement of the energy available in a battery at a specific point in time expressed as a percentage of the maximum capacity of the battery.

The SOC setting lets you choose the minimum backup energy that will be available at any point in time. Your selected SOC will be maintained while solar or grid power is available. Backup energy will be available during power outages until the battery reaches a minimum SOC of 10%, whereafter the system will shut down until solar or grid power becomes available to recharge the batteries again to the selected SOC.

By setting a higher SOC, you ensure that you have a high level of backup power to use during power outages. Setting a lower SOC can help you increase your savings on your electricity bill. 

It’s important to find a balanced SOC to optimise your savings while still providing sufficient backup power when needed.

You are in control of your SOC and there is no limit to the number of times you can change your SOC. It’s important to proactively manage your SOC and energy consumption during scheduled power outages to allow sufficient time for the batteries to recharge before the next scheduled power outage.

Stage Zero system learns how and when you use power and can predict your future energy requirements. If you have an abnormal event or an “out of the normal” expected load, we advise you to set your system to “Default” to ensure maximum backup protection.

Where the selected SOC is lower than 80% (not set to default), contracted protection during power outages is not guaranteed.
