Solaredge Consumption Meter - display problem on dashboard

[SunEagle]

I have to agree with solar pete. If there is any power going through the B phase then by removing the CT wires at the terminal block could result in an electrical shock.

Please get the installer or an electrician that has the proper personal protective equipment to do this work.

Whoa...hold the phone, while I have no doubt eah123 is right, in most cases anyone who is not qualified who messes with this will void there warranty, I would recommend you get onto your installer and suggest a bad review is coming their way if they dont get this sorted ASAP

[eah123]

Thanks for you help... Here's a picture of my meter. Would I be switching my red and black wires on the left side?

Where it says L2 on the left side you need to switch the white and black wires. I also suggest you place a short "jumper" wire across the L3 terminals.

OK, I assume that it is night time at your location? If that is the case, then your phase B CT is wired in reverse and you need to switch the wires on that phase.

[reggiethomas]

I just checked and the com light is on (or blinking really rapidly), and phase A (mine reads L1 CT) is blinking green and phase B (L2 CT) is blinking red.

The manual says that green blinking is for positive and red is for negative power. It's past 7pm here so there shouldn't be any positive power. Am I understanding that correctly?

See the manual, page 11 for the wiring diagram.

The troubleshooting of the meter is fairly simple. You need to observe it to confirm correct connections. Based on your picture, it is most likely located in the DC section of the inverter or an external box.

The meter is reading zero. So either 1) Communication is not correctly wired or not connected 2) Line voltages are not correctly wired or disconnected or 3) CTs (current transformers) are not connected.

If all status lights are off, then your problem is 2)
If Com light is off and phase A and B lights are on, then your problem is 1)
If Com light is on and phase A and B lights are red, then your problem is 3)

I'm hoping this thread isn't too old and I can get some help.I notified my i installer but as they use a contractor in my area, there hasn't been anyone yet to come look at my setup. I'm not sure what is setup incorrectly, but currently, my graphs are showing basically 0 consumption. Basically my consumption graph looks exactly the same. Here's what it looks like with all the options set.

If I were to select only Consumption, the graph would look exactly the same. It's clearly wrong as there's no way I'm using exactly what I produce. On the reports section of my dashboard, if I select Site Commissioning, this is what I see.

Meters
Verify that all meters are configured as planned

Export Meter	XXXXXXX	WNC-3D-240-MB	FeedIn	6,177	12/06/2016 17:14
Import Meter	XXXXXXX	WNC-3D-240-MB	Purchased	5,497	12/06/2016 17:14

I don't know where the numbers come from as they don't match my usage... they also don't match the graph.

Here is what my breaker looks like.

Any clues on what I can do?

Thanks.

CJ_Streamline BluePhoton Check that the meter is grounded and C CT is shorted ?

[CJ_Streamline]

While I understand what you are saying, the CT's are hooked up correctly. 1, when the Wattnode was installed, the inverter was turned off and both LEDs were blinking Green. and 2, before turning on the Self-Consumption, the monitoring was showing Grid Consumption correctly. If the CT's were backwards, it would have shown only consumption during the production time, and it would have matched the solar production as well.

I talked with SolarEdge's tech support and they said there is a setting or two they are having to adjust in the Power Control section. They didn't tell me what setting exactly, but he said he will inform me what was done when they do it.

[eah123]

BluePhoton Looks like you need to reverse the polarity of your CTs.

FYI, consumption = import when production=0. If import is negative because CTs are backwards, then the it assumes consumption=0.

If you open up the service panel at night, the CT LEDs should be blinking green. If they are red, the CTs are backwards.

Yes, I'm in the US, and an end-user. I did the wiring myself. It's not too hard, just shut all power off and avoid the exposed hot wires. Smart Energy Manager configuration is in the inverter - you have to take off the top cover to access the menu buttons. It's covered in these 2 documents. Just know that Export+Import means Feed-In+Purchased.

Great, thank you. I'll ask my installer for help... if not, I may try some things myself...

June 2nd Update:
I got in touch with our installer - CJ @ Streamline Solar here in Phoenix, AZ - he guided me through the steps to change the inverter configuration.

However, my dashboard now shows both production and self-consumption, but no pure consumption (the red). See attached picture.

Any idea on how to solve this final step?

Thanks again!

[eah123]

Yes, I'm in the USA. I'm an end-user, not an installer. I did all the wiring for the meter myself. It's easy, just need to be smart and not touch the hot wires.

Based on the information in your original post, I believe your CT's are wired correctly.

The Energy Manager is configured in the inverter. You do need to take off the cover of the top part in order to access the menu buttons. Hold down "Enter", enter the default password (12312312). Main menu->Power Control->Energy Manager
To activate: Limit Control -> Control Mode -> Export Control
Site Limit should stay as <-> (no limit)

Make sure the meter mode is set as Feed-in + Purchased.

Main menu->Communication->RS485-1 Conf->Revenue Meter->Meter Func.->Feed-in + Purchased

I figured it out after reading this in the meter installation manual:

Calculated meter readings, such as self-consumption, are calculated using the data measured by the meter and the inverters. Calculated meters are only sent when Energy Manager is enabled (for details refer to http://www.solaredge.com/files/pdfs/...in_limitation_ application_note.pdf).

At some point, the terminology in the firmware was changed from Export+Import to Feed-in+Purchased!

[BluePhoton]

Ah, solved it! Feed in = export (grid feed-in). Purchased = import. ButchDeal, you were right, after staring at a number of wiring diagrams, I realized that the generated AC is fed through the backfeed breakers and bypasses the 2 incoming hot wires. So the CTs over the hot wires reads purchased energy when current runs in one direction and exported energy when it runs the other way.

Also, to read correctly, I had to reverse the wiring on the CTs. To calculate consumption and self-consumption, and make it show up in the monitoring portal, you have to enable Energy Manager.

eah123 - Great that you now seem to have it working: Gives me hope that it can finally be resolved.

A few questions:
- Are you in the United States? (Back in November, SolarEdge told my installer that this feature was not enabled in North America)
- Are you an end-user? Or an installer?
- Were you able to rewire yourself? Or is it something an installer should do?
- Is "Energy Manager" available in the consumer portal? Or is this something the installer has to configure? (I don't see the option)


Thanks!
