what is the max wattage the unit can handle? (it can't be 80 X 600?)

Hi there,
I have heard that Morningstar are bringing out a high voltage MPPT unit next
year.
This unit will run up to 600 Volts.
In the mean time what other units are available that allow for higher than
150 VDC from the array.
I want to avoid the expense of using a Sunnyboy at the array and br
Thanks for all the info. This group rocks!

Wow. That is so different from our experience. Again, Enphase has been
spectacular about replacements, but we're talking dozens out of the
1000+ inverters we have installed. I wonder if it is an environmental
issue. It's hot around here in Florida...

We have over 1000 Enphase units installed of multiple types - mostly M210s
and M190s. We just had our first overt failure of an M190. It just went
dead after a couple of months of operation. I'll keep my eye out for
underperforming units but haven't noticed any yet.

I was ready to order Enphase 215s with the MC4 connectors when I was told by
the distributor that these micros with the MC4 was for the Ontario FIT and
more expensive so I should go with the Anphenol H4 connectors on the US
version. I was leary of using different brands ever since I read

Jeremy,
I understand that your application wants the wireless communication load to
operate at 24VDC with a voltage tolerance of +-4V (15%). Since your battery
bank will operate between voltages larger than +-15%, you will need typically
22-30V/24V DC/DC converter with max 15% voltage tolera
I did some research on this a while back, and one thing I learned is
that a switching regulator is more efficient than a linear regulator,
which may be important to you in this case if battery or energy
production capacity is a concern. You probably don't have to worry about
low voltage because you
I've never installed a M210, but we have had dozens of M190 failures,
mostly within a short period of time after installation but a few older
failures have trickled in lately. On one job with 236 208V M190's, we
have replaced about a dozen. To date we have not had a single M215

Has anybody else installed on this type of roofing?
