[RE-wrenches] Outback FM80's connected to Hub

[darren at solarhacker.com]

Benn,

When the FM80 are connected to the HUB the following are possible

Sharing battery temp sensor value from the FX for temp comp.

Float mode coordination, i.e. when one FM80 transitions to Float charging the other
will be commanded by MATE to float mode.

The FlexNet DC can terminate a bulk/absorb charge via the MATE when FlexNet DC determines the batteries have received a full charge for the day.


Cheers

Darren



Wrenches,
I have just set up an off grid system for a client and am now weighing out the pros and cons of connecting the two FM80's to the Hub or leaving them charging the battery independently.  
The system consists of an FW1000 with two stacked VFX3648's.  The two FM80's are mounted under the inverters and each is connected to it's own array. One is 3.4kW on a roof and the other is 3.6kW on two poles.Outback has commented on this and has offered no convincing reasons for connecting them to the Hub.
Any comments or experiences?
Cheers,benn
