Answer:

Currently, the limitation on the number of batteries connected to the same EnergyHub system is determined by the number of ESOs connected to the DC grid.

You can read more about what an ESO is here

An EnergyHub can currently communicate with up to 19 ESOs. This means concretely that a DC grid can contain up to 3 larger batteries (81 kWh each) or 10-15 smaller batteries (14 kWh each), based on the number of ESOs.

In the scenario where you approach the limit, always contact Ferroamp for further consultation.

Example:

We want to install an EnergyHub system with 3 M1 batteries, each having 81 kWh of energy and 6 ESOs at 6 kW each per battery, totaling 108 kW of power. This means a total of 18 ESOs in the system and will work well.

Now, we want to install 5 M1 batteries, totaling 405 kWh of energy and 108 kW of power. The number of ESOs in this case would be 30. This exceeds the recommended limit of 19 ESOs. In this case, contact Ferroamp for further consultation.

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.
