Figure 1 – BATTERY Networking Communication Ports
In a string of batteries, the two batteries at the ends of the communication chain will have one of their RJ45
“BATTERY” ports remaining un-utilized. On each of these two batteries, the “BATTERY” communication port
that is not occupied by a cable will have a 120 Ohm terminator plug installed in the open port (see Figure 2
below).
Figure 2 – Terminator Plugs at Either End of the AmpliPHI Daisy Chain
Use CAT5 or greater cable with RJ45 plugs (not included with the AmpliPHI product) to connect between the
“DEVICE” port on either one of the batteries at either end of the daisy chain, and the “ComSyncIn” port on the
Sunny Island (pictured in Figure 3 below). This connection creates the closed loop communications bridge
between the AmpliPHI battery bank and the Sunny Island. The cable length from the AmpliPHI battery to the
inverter cannot exceed
98 feet (30 meters).
