The latest Outback product guide very specifically identifies the
maximum PV wattage for the FM60 and 80 at each nominal voltage. But
I see it's also in their website (middle column FM80, right column
FM60):<br>

<div>Wow!</div>

</div>
<div>The most I have in one Outback install is 8 MX60s and 8
VFX3648s.</div>
<div><br>
</div>
<div>Overall the customer has been happy with the performance and
the stacking power save feature helps with idle power draw. <br>
<br>
As for the OPs request, the most PV still remains to be about
5000 watts gross power per controller (80A x 50V / 0.80), even
if they slice it up as high voltage or not high voltage type
controller. </div>
<div><br>
</div>
<div>Another curious idea is the cost per volt<span
class="Apple-style-span" style=""> when comparing 150V input,
80A Output controllers to the new high voltage input
controllers. That cost consideration spreadsheet is still
under construction.</span></div>

<div><span>I have a system in operation since 2003 using 13
paralleled Outback MX 60 CC and I have measured over 600
Amps at 48 Volts.on the common bus. Outback and I
replaced the fans in the MX 60s but we have had no
failures. This power is converted to 60 hZ using 12
Outback inverters, I have had an inverter trip off on
the DC side just the other day and I will check it out
this comming week but no problems. </span></div>

High-voltage DC input (up to 300Vdc)

for a large off-grid system.<br>
Not locked into 48Vdc. Can go up to
108Vdc (nominal) if needed.<br>
<br>
Any such CC units available?<br>
<br>
If not, what's been the collective
Wrench experience in paralleling
multiple<br>
controllers of whatever max output
amperage exists on the market? I
realize<br>
a paralleled configuration of this
nature would entail multiple separate
arrays<br>
in use on the input. That won't be a
problem. Just need to be able to feed<br>
the common battery bank.<br>
