As some of you might have heard, Enphase is bringing to market their newest
micro: the M240 which is already listed on the California Solar Initiative
website.

Are any of you beta testing this bugger?

I would be interested in hearing about other wrenches' observed Enphase
failure rates.
Since 2010 we've installed 1347 total Enphase units with an overall failure
rate of 3.27%
Our breakdown is as follows:
- M190 - 19/362 = 5.25% failed
- M210 - 21/545 = 3.85% failed
- D380 - 3/101 = 2.
What a surprise to receive a phone call from Fronius after 5 months and
numerous promises to return calls and emails. I'm guessing they got wind of
recent complaints on this list. The tech, after making a few more excuses, did
say that the payment will now be processed. So, in fairness, I am re
Let me tell everyone about my Enphase M190 experience. I installed 113 of them
on a roughly 25kw array several years ago. About 3 months after installation
the inverters started to piecemeal fail, until the replacement count was close
to 20. Mind you they were replaced at $150 a pop, which Enpha
All of my enphase failure are in the desert (Utah)
We have had Power-one units in the field for 5 or 6 years.

Jason, in many states including CO with a state rebate program, we are
required to have a 10 year warranty for labor & materials. It is 100%
coverage for the warranty period. Any replacements have been out of our
pockets for the labor response.
Living on the coast of Maine, the majority of our M-215 installs
(approximately 200) are along the immediate coast, say, within a couple
thousand feet of salt water. We have had zero failures of this inverter
(M-215) since it came out. We had one non-coastal issue with AC Out Of
Frequency events th
Another option would be to compensate the customer for lost production
until you're out there to replace a second inverter. You can credit this
against Jason's diagnostic fee idea and/or the $150/unit reimbursement
from Enphase. Each unit down is about $30-60/year depending on location.

This is fascinating - the majority of the Enphase failures reported on this
list seem to be near coastal areas. I know that is true for us. We've had
extensive failures on the M190 and M210 units close to the ocean. We have
yet to have a single M215 failure so I have my fingers crossed.

Why would you "rip apart an array?" We only remove one module in almost
every case, replace the WEEBs, replace the inverter, and we're done. If
there are more than two rows of modules, you might need to remove an
additional module or two, but that takes almost no time. Our steepest roofs

Wrenches,
I have had extensive failures on 3 installs that are situated right on the
coastal bluff in Northern California. Once you replace more than one
inverter at one site on one day, the compensation goes from $150.00 per
inverter, to next to nothing for the remaining. Enphase actually sent out
It's funny because I've had a very different experience from everyone else.
I've had lots of Xantrex inverters fail and a few Fronius but not to the extent
that everyone else has. I've only replaced a few Enphase inverters and they
were usually dead out of the box.
Thanks,

Yeah I too agree. Bring the techs from Enfizz out & put them on a 12/12 pitch
roof, 2 stories up and see if they feel "adequately compensaited"! This has

How is that possible?
I get a lousy $150 dollars from enphase to rip apart half of a array just to
