# I added a battery in ‘My Components’ but it isn’t showing up as an option in the Inverter task.

When you add a battery component, you must ensure that you have set the compatibility with your custom inverter category or specific inverter:

1. Create battery component
2. Under battery rules select '**Selected inverter groups only'** or '**Selected specific inverters only**'
3. Click on the text to show the different inverters and select the check box under your relevant inverter group or inverter

If this does not resolve the issue or now too many the options are showing in red, you will need to look at the **max battery capacity** value in the **Battery** section of the hybrid inverter and compare this with the **battery capacity** of your custom battery.
