Integration is possible
In principle, the integration of batteries in the DC circuit is possible. Ideally, they should be integrated via charge controllers so as to operate the batteries as sparingly as possible.
Please bear in mind that this deactivates the excellent turbine control of Windy Boy inverters.
We would be pleased to supply you with our Sunny Island products for intelligent battery connection. Further information can be found on our homepage under Products > Off-Grid Inverters.
