Answer:

Yes, it is possible to secure an EnergyHub with a type C-fuse. Generally, Ferroamp recommends securing with a B-characteristic fuse. This is because it has a faster tripping time than C-fuses, which is advantageous for an inverter in general.

However, if the rest of the property's electrical system is secured with type C-fuses and it is easiest to access C-fuses, there is nothing technically preventing the EnergyHub from being secured with them. The electrician performing the installation ultimately chooses whether to use a type B or type C fuse based on what is suitable for the electrical system in the property.

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?
