Best consumption meter for solaredge inverter

[flynhawaiian]

Awesome. Also when you do the pvoutput thing what meters are you using to connect up to it? Can you just use the Solaredge server data?

Does anyone have a picture of the install? I'm looking at which wires are tapped. Basically it seems like the CT goes on the mains coming from the power company, but the tapped wires are they they basic breakers from each line?

Take a look at this thread. It has the pictures of my install:

Also, on my first day, I was able to generate 39kWh from this system (I live in Los Angeles with an ideal roof orientation for Solar). Does this sound reasonable for an 82 degrees cloudless day based on my system size? Thank you!

We have nearly identical systems. I have a 6.615kW system w/ 21 Panasonic 315W panels, P400 optimizers, and an SE6000H inverter, and I live right at the Eastern border of LA County. You will likely be seeing clipping with the SE5000H inverter on these clear days, esp. during the cooler Spring days. Here's my production graph for 5/27 and 5/28:

There were morning clouds on 5/27 so lower production in the morning. 5/28 is a bit more representative of a clear day. In April when it was cooler I had production in the 47-48 kWh range, with a couple hours of clipping at 6kW during peak sun. With the SE5000H inverter, you'll likely be seeing a 'Devil's Tower' production graph as the production clips at 5kW. Depending on how bad the clipping looks, it may be something to raise with the installer about the possibility of switching to the 6kW model inverter.

Hello All,
I know this is an older thread and probably rehashed elsewhere, so I apologize if this is not the right thread. I am new to the forum and new to the solar family (just had my system turned on this past weekend). I have a 6.6kW (DC) system using 20 Panasonic 330W panels and P400 optimizers with a Solaredge SE5000H inverter. As everyone points out, consumption and net usage is not monitored unless you add a modbus meter and my solar company is saying they can add a Solaredge option for $450. But I also see here that there is a Wattnode option with CT clamps for anywhere from $25-$50 on Ebay and elsewhere. Are these really the same type of solutions that do the same thing? Is it easy enough to install the modbus (whichever one I choose) yourself, or better to call an electrician (and what can I expect install costs to be)? I'm having trouble understanding how best to get consumption metering installed on my system so I can track performance against use, without getting hosed. Also, on my first day, I was able to generate 39kWh from this system (I live in Los Angeles with an ideal roof orientation for Solar). Does this sound reasonable for an 82 degrees cloudless day based on my system size? Thank you!

Congrats on your system!

Take a look at this thread. I also purchased my Wattnode modbus meter from ebay for $25. It is working great. In this post I added installation manuals and pictures of my setup. Feel free to ping me if you have questions:

Wattnode makes the meter for SolarEdge. They make many many different units though, and only a few will work properly with the inverter you have.

If you have attic fans, check them to make sure they have not seized. I had that issue the first month I moved to the house and the electric bill was astronomical and I had a breaker flipping whenever I plugged in something on that circuit. Ended up that one of the attic fans was seized and the other one was on its last leg. Apparently they only last about 7 years (or so I'm told).

Count your blessing, that that attic fan seizing could have turned into a fire. Dodged a bullet by being somewhat attentive on your consumption.

Cool fact: If you go with larger CT's, you can improve the resolution of the measurement by looping the wire to make 2 (or more) passes through the clamp. I got two loops in on my revenue grade EKM meter, 3 passes, which increased the resolution from 800 pulses / kWh to 2400 pulses / kWh. It may sound like overkill, but for reading 5 min average power, that improves the resolution from +/- 7.5 W to +/- 2.5 W. (An energy meter with 1 Wh resolution can report average power to +/- 6 W)

Can you post a pic of the looping you are talking about. Is this what you mean? I don't think it is overkill. I have had a Neurio installed in my main panel since thy first came out and it reads more precise than the SolarEdge Modbus meter. If by looping around my 200 amp clamps i can get better resolution than i will be a happy man.

The Neurio is an awesome device as it has helped me track down the energy consumers, phantom loads, etc. Heck if i turn on a led light bulb it instantly registers on the phone app letting me know the increased watts i am consuming

Ahh, so the SE site doesnt allow for tracking circuit level, just total consumption.

Correct, it just gives you the total consumption load and it updates the monitoring site every 2-3 seconds. So if you turn on a light, you will see te additional load it puts on the service.

[macaddict]

I need to figure out why my last two months have increased consumption by over 500% from last year, or at least start tracking to kmow for future major discrepencies. But I could probably figure it out just by monitoring three circuits: AC (heat wave here has been crazy) the EV, and dryer. Those three I estimate at least 70% of this June & July usage.

Charlie, the link from macaddict is the same unit you have installed? Inspron, youll need CTs, I dont think it comes with any.

The unit I purchased came with the CT's.

[macaddict]

Any follow-up on your installation?

Yes, I installed it without issues and it is working great. I'm attaching what the Solaredge monitoring system looks like now that it is capturing consumption.

When configuring the inverter I had to assume some settings as the manuals are out of date. Specifically there is not longer an option for consumption meter on the modbus, only multi which is what I used. I chatted with solaredge tech support the day after i configured it and they said I did it correctly.

I have to say that I have a much better understanding of my consumption and it is leading me to change my consumption habits. For example, i never knew that my "top of the line most efficient Lennox AC uses up to 6 times my baseline usage.
