# How do I change the size limitation of a homeowner's Dura-i G3 inverter?

This can only be done during the commissioning of a G3 inverter.

Log in to your Installer account on the Dura-i app and proceed to commission the product. Towards the end of the quick set-up for each G3 inverter (after the inverter ‘On’ button and before the ‘Finish’ button), there is a section called ‘size selection’ which states the current model name and size with 3 options: 3.6k, 4.6k and 5k.

Select the size which aligns best with the individual's DNO allowance for grid export and click ‘OK’. This process usually takes between 3-5 minutes.

Once complete, hit the ‘Finish’ button to finalise your commission.

Provided in the inverter box will be separate side stickers for the inverter. **You MUST change the sticker to reflect the new size.**

**Please note** that this change can only be made once, and the final sizing MUST reflect the current design of the electrical installation with electrical safety and MCS guidance in mind.
