# I added a hybrid inverter to ‘My Components’ but can’t add a battery to it in the inverter task.

If you are trying to use custom hybrid Inverter and battery components - you will need to make sure you have added the battery as its own component. This is true even for all-in-one systems.

You can do this under **Components** > **Edit Batteries**. For more detailed instructions, take a look at our [guide to setting up batteries in Easy PV](https://help.easy-pv.co.uk/books/creating-components/page/custom-battery "Custom battery").
