Helpful Tips:

•

The interconnecting busbars’ ratings should match or exceed the AmpliPHI Battery bank’s

total surge rating.

•

Busbars for paralleling more than two or three AmpliPHI Batteries can be sourced from

outside suppliers or custom ordered from SimpliPhi.

•

SimpliPhi recommends paralleling AmpliPHI Batteries using interconnecting busbars (not

battery cables) for AmpliPHI Battery Banks consisting of more than 20 batteries for a cleaner

installation.

•

Best practice involves wiring the battery leads to opposite ends of the busbars.

•

Size the battery cables leading from the interconnecting busbars to the Balance of System

equipment using the National Electrical Code’s Conductor Ampacity tables.

CAUTION: Do not reverse polarity. Use a voltmeter to check polarity before making

connections to the battery terminals. Reversing polarity will Void the Warranty.

4.7 – Communications Wiring

CAUTION: The maximum number of AmpliPHI batteries that can be installed within a single

bank is 40.

Each AmpliPHI battery includes three RJ45 ports, compatible with CAT5 (or greater) cable. Two of these ports are

used for connecting between the AmpliPHI batteries in a battery bank (“daisy-chaining”). These two ports can be

identified as the “daisy-chaining” ports because they are in close proximity to one another. The third port is used for

the communications connection between the AmpliPHI battery bank and the inverter. Only one of the AmpliPHI

batteries within the battery bank will utilize this third port (either the battery at the head or the tail of the daisy-

chain). AmpliPHI batteries with un-utilized third ports may plug those ports using the RJ45 dust caps provided with

the battery.
