# I have selected a custom inverter and it isn't showing the right number of strings. How do I fix this?

On each inverter, you can see:

1. The number of inputs (MPPTs)
2. The number of strings on each MPPT

If the number of **inputs** is incorrect, you need to add more trackers in the **Solar** section of your custom inverter. The number of inputs will correspond to the number of trackers in this section.

If the number of **strings** is incorrect, you either need to adjust the number of allowed strings or check the current value in the **Solar** section of your custom inverter.
