but it also takes MUCH less time in most cases and can be done much more
easily by one service technician. It's not a money maker, but it covers cost
in our neck of the woods.
How is that possible?
I get a lousy $150 dollars from enphase to rip apart half of a array just to
get at
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
ALWAYS BEEN an issue for this industry. We recommend products, buy the
products, without us the manus don't HAVE jobs and we are left trying to
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
here are
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.

Since we stopped using micro-inverters due to the high failure
rate
We were hired just to install the system by a local firm that designed and
sold the system and have had a bear of a time getting paid from anyone.
this is why i never touch materials i do not sell, or install designs i did not
do.

Since we stopped using micro-inverters due to the high failure rate, network
problems, difficultly in replacement – I've been using the power-one inverters
a bunch because the dual channels solve most of tricky issues like different
roof aspects, shading, and uneven strings.
However, they are
7 to 12 kW for residential systems? wow... its hard for me to believe there
is not some waste there.
I have found that the home owner's target system price point has stayed the
same over the years even as prices have fell. So our systems have just gotten
bigger to cover more of their loads.
Hi Troy,
The Sharp Sunvista JH-3500U stopped being produced in 2005ish. Fronius and
Kaco may have products with 3 MPPT inputs.
Sorry to hear about your trouble with microinverters. I'm guessing those
were older units. Our current line of products has had extremely low failure
I suspect that the early failure rate on the M215 is tiny next to the M190.
Most of the M190's that did have failure problems early on failed very soon
after installation in my experience. After the initial duds died, the
failures on most M190 systems dropped off. I'm not seeing a linear failure
What you are asking for is the Sunny Tripower 10/12/15/17 3 phase 2 mppt
input inverters, which we are using in the 415V locations but are not
available in the US. I don't understand why, they are fantastic units. The
units have up to 6 string inputs, string monitoring, built in electronic
safety
Jason,
I'm one of the many installers who still won't touch a micro yet. It's not so
much that there were failures early on, it's how companies like Enphase HANDLED
them. My understanding is that you basically got a replacement inverter and got
stuffed for your time and travel. That may have

Bob-O,
Fronius is not good for reimbursement anymore. While they used to be, Fronius
has refused to pay for warranty service. Since December, 2012, they have
refused to reimburse me for an inverter swap that THEY told me to make. The
display had an intermit ant problem. When I swapped out the
