Answer:

Yes, the EnergyHub system is scalable, and additional Solar String Optimizers (SSOs) and/or batteries can be added.

What you need to check is that you have enough connection points in the distribution box / distribution cabinet / ESS Power Case to connect the new units, and that the EnergyHub has sufficient inverter capacity to convert, for example, the newly installed solar production.

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.
