Re: [RE-wrenches] Optics RE with two hubs.

[Lones Tuss]

The Flex net DC can be used with up to three shunts.
It will give individual shunt information as well as overall total of the three.
The actual labels do not matter other than easy identification.
But if you do want to label them it is done in the Configuration Wizard
I would recommend installing the FNDC on the Mate3/Hub combination used with 
the inverters.
It is nice to have SOC, Dc Voltage and Battery Temperature viewed with the 
inverters.

Do I really need the PV shunt?

Yes for the FNDC to be accurate all paths into and out of the batteries must go 
through a shunt.

I can’t seem to find the screen where you label the charge controllers.

The Mate3 with the charge controllers will label them as Port 1-10.
You can assign a name to a shunt you cannot assign a name to a charge 
controller.

Each Mate has its own Mac address put both Mates under the same site name.

Just to clarify OutBack usually uses a 500 amp 50mv shunt.
500/ .05 = 10,000 to 1 ratio
It is possible to use a 1000A 100mv shunt
The 10,000 to 1 ratio is the same.
This can help with larger systems.
I apologize for the piece meal response.
There are several questions here that had to be dealt with individually.
I hope this helps.

Nope doesn't care.
You could have 1 shunt or 3.
You just get to monitor the 3 shunts.

I am setting up an Optics RE system with a system that has 8 FX inverters and 3

The inverter Mate3 and Flexnet connects into one 10 port hub and the PV Mate3 
connects into another hub with the charge controllers.

Do I really need the PV shunt?  How is the Flexnet processing charge current if 
it does not know there are charge controllers?

I can’t seem to find the screen where you label the charge controllers.  I am 
used to setting these up with Radians.  Am I missing something?

Any help is appreciates. Because when I posed this question to Outback and got 
the audible equivalent to a blank stare:


Thanks in advance,

Hi William,

Yes you need the shunt for PV the FNDC to read correctly 

I'm not sure exactly what you mean about labeling the cc?
The FNDC doesn't care what each shunt does. Cc, inverter DC loads etc, if 
that's what you mean

[RE-wrenches] Optics RE with two hubs.

[William Miller]

Friends:



I am setting up an Optics RE system with a system that has 8 FX inverters
and 3 charge controllers.  I installed two Mate3s and a Flexnet-DC.  I need
two shunts for the Inverters because 4 are connected in one DC1000 and 4 in
the other.  I installed a third shunt for the PV.



The inverter Mate3 and Flexnet connects into one 10 port hub and the PV
Mate3 connects into another hub with the charge controllers.



Do I really need the PV shunt?  How is the Flexnet processing charge
current if it does not know there are charge controllers?



I can’t seem to find the screen where you label the charge controllers.  I
am used to setting these up with Radians.  Am I missing something?



Any help is appreciates. Because when I posed this question to Outback and
got the audible equivalent to a blank stare:





Thanks in advance,
