Since this system already has a hub to stack the inverters, the charge
controllers may as well be connected to it. The cat 5 cables are
cheaper than extra temperature sensors. The advantages of being
networked: The temperature compensation is coordinated with a single
temperature sensor. Both charge controllers will change operating
modes together (the older MX 60 wouldn't do this) so one isn't in float
while the other is still in bulk mode. The equalize command from the
Mate is global so the charge controllers are supposed to equalize when
you set the inverters up to equalize (the MX 60 was <i>supposed</i> to
do this to). I don't know of any disadvantages, but the advantages are
actually pretty minor.<br>

<div>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. </div>
<div><br>
</div>
<div>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.</div>
<div>Outback has commented on this and has offered no convincing
reasons for connecting them to the Hub.</div>
<div><br>
</div>
<div>Any comments or experiences?</div>
<div><br>
</div>
<div>Cheers,</div>
