Answer:

This could be due to the system being configured to limit export to the grid, which is common during commissioning if the electricity meter has not been replaced with one that can register export. It could also be because the EnergyHub has an incorrectly set value for the CT ratio. Check the CT ratio on the display by pressing it for 5 seconds to access the service menu.

We constantly want to improve the content in the Knowledge Database and would appreciate it if you give feedback on our articles. Does all the information exist, is there anything that needs to be clarified or is there any information that is missing that would help installing or using the EnergyHub system in general? You can give us feedback by choosing if the article was helpful or not in the options below.
