Large scale system design

Hi there everyone.

I have been involved in the renewable energy sector for a number of years now, and have installed many small scale systems but have been asked to be involved in the design and install of a large scale system. I understand that 6 x 15kw multiplus II units can be connected in parallel totalling 90kw for one phase, and that three sets of these can be connected together for a three phase installation. So that would be a system totalling 270kw for the 3 phase installation.

This would be sufficient for the first stage of the project, but as the project is expanded in years to come, is it possible to add another independent 270kw system to the existing installation on a common three phase bus supplying the facility?


Thanks in advance,

Daniel.

The maximum for one system is 180kVA with 12 of the 15kVA Quattro (4 on each phase).

Connecting multiple systems together is not possible or at least not recommend/officially supported.
