Respectfully, that may be, but the FCC is allowing it. If you want the
issues fixed, and fixed for good, pressure the FCC to enforce in a way
that works...
As long as the government allows this, it will continue. It happens
this way in all aspects of law enforcement, look at cell phone use in
cars...

Hi Dale,
It actually might be cheaper to do just, fly an engineer out to a
few RFI events to create a service bulletin.
Lets say the vendor sells a thousand of these PV systems each year,
(and I bet is is quite a bit more), if each one takes two ferrites,
and one hour of time to install, that is say-- 10 bucks in ferrites,
and 10 bucks in installer time, or 20 bucks per system.
If they sell a 1000 of these a year, that is 20K a year they save by
not installing RFI suppression on every system as it leaves the
factory. A good business decision.
Once the engineer gets a fix, and puts it in writing, making it a
service bulletin when RFI is reported, it will be a lot simpler,
(read that as cheaper for the vendor), for the install tech to do it
next time someone gripes about RFI...
It will also be a lot better for us, as the installers can suddenly
fix the RFI sooner than later, which is a LOT faster than flying
anyone out to do anything...
This in fact is probably a very good business decision to have the
engineers fly out and get hands on with actual RFI event and meet an
actual Amateur operator.
I am sure that is why the engineers are flying out-- to see the
actual issue as it happens. This means that the vendor has put a
high priority on fixing RFI, and is willing to spend some money to
fix it. This is great news for us!
This by the way, is a very good bit of customer service by the
vendor. We need to be very thankful that they are not dragging
things out as say-- W6WBJ has done. The vendors could do just that,
and they are choosing not too, they are choosing to help us in
this... Even though the vendor is responsible for the RFI, they are
still our friends.
As much as I like the idea of having every solar PV system have RFI
suppression installed from the get-go, that is simply not going to
happen-- period. No matter how mad we get, no matter how loud we
carp about RFI, the vendors are simply not going to do that.
It is far cheaper to correct the relatively few problems the Hams
report than to proactively fix every system as it leaves the factory.
We MUST maintain a good relationships with the vendors that take the
time, and money to fly out engineers to solve a problem that for
them, is nothing more than a costly pain in the ass. They are
helping us by listening to and responding to our problems.
We need to support the vendors that help us removed RFI issues by
sending high cost engineers across the country to make an RFI issue
go away... They could always just ignore the issue and not help...
73s and thanks,
Dave

I should think it would be a good practice for this company to
fix their installation procedures so they don’t have to fly an
engineer out to fix things. Seems like a poor way to run a
business.

Most of the SolarEdge house rewire jobs I have had around me
solved the
problem on the first attempt. One took about four visits
before it was
finally solved. On that final visit an engineer from
SolarEdge came out.
He discovered that they missed a couple of the optimizers.
Even one
unfiltered optimizer will cause RFI 100s of feet away. So,
keep after them
since they probably missed at least one optimizer.
Randy:
I've been in touch with Solar Edge field tech Tom Simpson who
will be flying in from the west coast to inspect the work. He
thinks the installers missed something which, as you mentioned,
isn't the first time this happened. He tells me he's handled
many cases and said the noise will be gone once he finds the issue.
Will keep you posted.
