The electrician is here working today.

UPDATE: It’s all done.

Inside the Basement

Wall Before

This is the wall in the basement before anything.

Wall Blank

This is the blank wood before installation of components.

Inverters Open

The inverters (top) and DC disconnect switches (bottom) are installed.

Inverters Almost Done

Here are the inverters with their covers on, and the switches partially wired.

Inverters Complete

Here’s the completed installation in the basement. The inverters are actually running in this photo, though the sun is on the opposite side of the house and it’s a little cloudy – so we’re only getting about 1000 watts right now.

Inverter Label

This is the label from the side of one of the inverters.

Outside at the Meter

Outside 1

This is the initial installation of the wires. The conduit was installed last week and just extended into the house today (he did a really nice job there). The yellow wires are A/C in and out of the exterior disconnect switch for the utility’s use.

Disconnect Switch 1

Here are the disconnect switches partially installed.

Outside 3

Here is the completed product – utility disconnect switches – outside (except for required labelling).

Disconnect switch 2

And here are the required labels on the disconnect switches.

All work is complete! YAY! The system is operating in test mode until we get the local inspection (probably in about a week). Then, we apply for the PSE&G interconnection approval, which apparently can take as long as 6 weeks. The system will be turned off between the inspection and PSE&G approval.

The meter REALLY DOES turn backwards. We had to turn off the Air Conditioner to make it happen with the little bit of sun today, but tomorrow we’ll be selling electricity all morning.

  2. My issue with the Sharp SunVista’s is that you cannot get information out of them except via the LCD. Which doesn’t lend itself to detailed monitoring and trending. And they appear to be one of the only inverter companies that DOESN’T offer a serial port outlet for computer users.
    It’s a good inverter, but the Sunnyboy or Fronius do what I need (I can live without unbalanced “strings” of panels, but it limits expansion a bit). But knowing that it’s running 5% less efficient that last month (dirt) or knowing that I’ve generated enough power to be 1/3rd of the way through paying them off (and after that it’s just money in my pocket) is kind of important to me.

  4. I believe that Sharp is working on a data acqusition system (DAS) for these inverters. However, the little that I can find on the web leads me to believe that this will cost around $1500 per inverter!
