[RE-wrenches] Power One Microinverters

Fri May 31 10:55:05 PDT 2013

I have eight P1 micro installs in operation.  So far so good though the
range of the wireless communication system can be iffy especially when
dealing with metal roofs, of which we have a lot in these here parts of
Hawaii.  The fix is to relocate the CDD (their data logger) antenna closer
to the array using a 15 meter cable.

I think the graphics for the on-line monitoring system are clean and easy to
understand.  

Finally, I've seen the 250 micro put out as much as 259 watts and the 300 go
as high as 312 watts with a 96-cell mod.

I think you misread my email.

That's my point. Why not eliminate the gateway?! Of course, the same could
be said of the Enphase Envoy if they embedded the gateway functionality in
the inverter and just used powerline communication to get to the Internet
via the router with a simple/cheap powerline->ethernet gateway.

I'm sure they thought of this and it just comes down to economic viability.

Power One does not eliminate the gateway. The just connect to it by wifi.

Any updated impressions of this product? I'm starting to see an uptick in
these being sold by competitors. 

One thing that would be nice is if they eliminated the gateway, allowing
each inverter to connect to the Internet by Wi-Fi. This would eliminate the
extra piece of hardware, and the possibility of the gateway device failing
in the future. Understandably, this would probably increase the inverter
price, but for small installations, it would be more cost effective I would
think.

I have 9 of the PowerOne microinverters on the roof of the old AEE building,
running for a few months.  They work great so far.  I like the monitoring.
It connects to the inverters by WiFi.  I don't think they are selling them
yet.

Here is a link to the on-line monitoring.

Hi Bruce,

I haven't received much feedback from the group yet on the Power One
Microinverters. Marco was in-progress on a job with them and was going to
get back to me off list after completion. 

I'm weary about the wireless communication because wireless always seems to
break down at one point or another over the long haul. However, I should
reiterate that I have no experience with this product yet. 

Best, August

Hi August.  I'm curious about these inverters as well.  Have you learned
anything outside of the Wrenches list about their track record?

Take care.

Hi Wrenches -

Has anyone tried out the new Power One microinverters?

nel-products/aurora-micro/series-0

Seems like a similar concept to Enphase M215 as far as the trunk cabling
goes. However, their monitoring device called "Aurora CDD" communicates
wirelessly with the microinverters compared to power line communications
with Enphase. They also seem to be at a higher price point compared to
Enphase although they are higher wattage at 250 and 300 Watts.

Best,

August
