Symmetra PX Paralleling for Capacity Question

[Anonymous user]

Can I parallel two Symmetra PX 500kW units together to achieve 1 MW?
or achieve 500kW N+1

I found this answer in the Knowledge Base section...but i'm not sure if it is current or not.
I also did know if that just pertains to the 80kw and below.

Topic Heading:*+This discussion discusses why it is not possible
Question: Can two Symmetra PX units be set up in a parallel configuration?

Answer: It is not permitted to connect the output of 2 Symmetra PX Units in a parallel configuration.
There is no synchronization device available for this model.
Even if both Symmetra PXs are connected to the same mains input, and have synchronized outputs when on-line there may be some phase shift in battery operation.

The UPSync (Synchronization device) is only available for the Symmetra Megawatt units.

Here is the link to it.

Yes, and no.

The technology and design is present to allow up to four SYPX 500k models to be paralleled, either for redundancy or capacity (up to 2MW). You can see the ports for parallel communication roughly below the display screen on the UPS, near the NMC slost. However, this functionality has not been added into the units yet, and so as of right now, you cannot parallel the units together. We haven't been given a definite ETA for this feature to be completed.
