But do not turn on the PowerWerx while the KX3 is running or you'll receive a nasty surprise.  There's a strong voltage spike from the PowerWerx that overwhelms the KX3 and the KX3, in response, shuts down.   If you plan to use the SLA as backup while mains power fails, be sure to turn off the PowerWerx before mains power returns.
