[RE-wrenches] SolarEdge

[Brian Teitelbaum]

Hi Nick,

I'm in that building. The system uses Sharp 185W (72-cell) modules, mounted on the roof. Even though it's a three-story building, it's not tall enough to catch any sun in mid-day because of three tall redwood trees in front of the building. The shading is not a problem for most of the year, but it sure is in January. We don't want to cut the trees....this is Redway CA, after all, so the Reds have their way.

The SolarEdge equipment was just installed about a month or so ago, so we don't have year-round data yet. The PV array was previously connected to a variety of inverters, including an OutBack PS1, and even an old Beacon M5.  I'm sure that the SolarEdge stuff will provide more output...when we actually get the sun on the array.

I was looking at the public systems on the Solar Edge site, but did not know which system was yours, Pekka.  However, I noticed that the system labelled AEE-Solar seemed to have an issue.  The production data for each day shows a huge drop in power during the middle of the day, which comes back up later in the afternoon.  That is not the kind of production that I would be looking for.  Can anyone explain what is happening to there?

Hello everyone,

I have installed four SolarEdge systems so far and am happy share my experiences  My first installation is available for public monitoring via monitoring.solaredge.com<http://monitoring.solaredge.com>.  It consists of 26 Aleo s_1.8 225W modules, 26 PowerBoxes installed on Unirac solarmount rail and SolarEdge 5000US inverter. It was commissioned on June 6,2010 and has produced 6.3 MWh of total energy.

Pros:
Module level monitoring
Centralized inverter
Safety voltage for servicing the system
Free internet monitoring & iPhone application

Cons:
Additional wire management and zip-tieing to the racking system
Homerun is DC so it needs to be inside conduit (vs. Enphase)

Tip: Remember to write down your serial numbers for PowerBoxes before installing the modules.

I am happy to answer any other questions as well.

Best regards,

Pekka Laine
