4.7 – Communications Wiring
CAUTION:
The maximum number of SimpliPHI batteries that can be installed within a single
bank is 72.
Each SimpliPHI battery includes three RJ45 ports, compatible with CAT5 (or greater) cable. Two of these ports
are used for connecting between the SimpliPHI batteries in a battery bank (“daisy-chaining”). These two ports
can be identified as the “daisy-chaining” ports because they are labeled as “BATTERY”. The third port is used for
the communications connection between the SimpliPHI battery bank and the inverter and is labeled “DEVICE”.
Only one of the SimpliPHI batteries within the battery bank will utilize this “DEVICE” port (either the
battery at the head or the tail of the daisy-chain)
. SimpliPHI batteries with un-utilized third ports may plug
those ports using the RJ45 dust caps provided with the battery.
Figure 4.5 – SimpliPHI Networking Connection Ports
In a string of batteries, the two batteries at the ends of the communication chain will have a cable occupying
only one of the “daisy-chaining” ports in the SimpliPHI battery. On each of these two batteries, the
communication port not occupied by a cable will need a 120Ohm terminator plug installed in the open port (see
photo). One terminator plug is included per SimpliPHI battery.
