DC Bus Design Notes 

 

4.2.1

 

DC Isolator 

The LiTE range includes an integrated battery DC breaker/isolator that breaks the positive 
cable continuity inside the battery. This breaker, on all Home and Business models, is rated 
for a 36kA fault (short circuit) current. The system therefore does not require another DC 
isolator or breaker except where required by local regulations, for example in relation to 
conformance with the Clean Energy Council of Australia battery design Best Practice Guide, 
which states, 

“S

hould the internal battery isolator not offer isolation of BOTH the positive 

and negative terminals of the battery, an external isolator is required that can isolate both 
the positive and negative cables/terminals of the battery

.

”

 

 

 

 

 

The approximate short circuit current values of each battery model are provided in the table 
below:

The external isolating device required for installations that are required to conform to the 
CEC of Australia should be designed to withstand these fault levels (short circuit currents) as 
well as the applicable current rating of the battery or the combined current ratings of all 
batteries connected to the isolating device. 

A single line diagram for a typical residential installation is provided in below Figure 4.1. 

4.2.2

 

Multiple Battery Connection 

Systems with multiple batteries must be installed such that the DC cables are the same 
length on all batteries, which must be routed to a common DC combiner such that the 
current pathway for all batteries to the point of load or charge is the same. The DC 
Combiner may be the terminals on an inverter if there is enough space, or a dedicated DC 
Combiner Box.
