Anyone got any experience of the Solar Edge PV inverter and optimiser?
Looks to be useful in shaded/shadowed installations.

Doesn't seem to do anything that others don't do.
The most commonly used inverters use here are Sunny boy an Fronius.
I think the issue you want to concern yourself with is reliability.
Insofar as anything at all can be discovered.

I thought the control it offered was much finer than the Sunny Boy in
that it looked at each panel every few seconds to decide whether or not
to include that particular panel in the array's output.

Agreed, which was one of the underlying reasons for the question.
There's so much kit out there, from a multitude of manufacturers, that
experience of any of it seems to be quite dilute.

Of course you can, its been done in the past, it will be done in the future.
the so called laws are created to fit the observations and may or may not
cover all circumstances.

The fact that one can do physics at all, Dennis is predicated on the
assumption that there are immutable laws of physics, whether we have
identified them correctly or not.

Your argument is typical of the green and wet behind the ears, that
suggests that the laws of physics can be changed by believing in
something different: Like the ability to store energy in your
imagination, rather than in nuclear or chemical bonds, or in the kinetic
energy differences between entities with disparate vector velocities.

The laws of physics do not change. We simply adapt our understanding of
them to meet more cases.

So says the man with a dubious degree in engineering to the man with a

Early days yet in the technology. There are several people in this
group have PV arrays. So far no problems. I have had one since April
ths year.
I expect if there are any problems it will be four or five years down
the road.

I would avoid the newcomers in this business. Sunny boy and Fronius
have been at it for a few years at least.

It does appear that this product offers finer control. Each panel has
its own maximum power tracker costing £50-60 each and must be used with
their own inverter. Retrofitting to an existing system is therefore
expensive. Their inverters are cheaper than Sunnyboy but by the time you
have added the optimisers the cost of power conversion is up by 25-30%
on a standard arrangement.
I believe I understand how they work but have requested information to
try and confirm this.
For a new installation it will possibly only add a few % to the total
cost and may well improve the output in the case of shading.
One item of bumpf from the company even suggests one system output was
increased by 1% even with no shading present.
