Solaredge Monitoring App - Consumption

[LDLP]

Hello All, My system is now two weeks old. i have been monitoring my system via the SE monitoring app online. One of the things i have noticed which i find weird is that when my system produces more, my consumption increases. For example normal morning and also at night when everyone is sleeping the benchmark consumption seems to be between 0.25w to 0.50w average. If my heater or fridge kicks on specially at same time it can reach 1kW. As my system start to increase production and when it reaches peak production near noon my consumption increase and can reach 2kW with no actual increase in electrical demand from devices in the house. Is this a configuration issue?

My System:
Solaredge SE10000H inverter
Panasonic EVP370
12.58kW system
LG 9.6kWh battery backup

I think the term consumption might be incorrect. What i see increase is the electrical input into my home. Please see picture below. it shows 1.56kW. This number fluctuates up or down based on solar production.

It sounds like you have not gotten the POCO to change the meter so it can subtract what you send to them. Some POCO's are slow in doing that and the customer ends up paying for the power being sent out when the home doesn't consume it all.

I would contact your POCO to see what they are doing or not doing to the power going to them.

Sorry what is POCO? if its our service provider for electrical we have PSEG and we did have a new meter changed about 7 days ago. I have noticed they did not change my account to reflect the new Net Meter on their website and billing currently still shows as if there is no Solar/Net Meter. i wonder if they still need to do something on their end.

Yes a POCO is the power company which it sounds like you have PSEG. If they have not converted the account to credit you when you Net Meter power back to them you may be paying for it which could be the answer to your problem of seeing a higher consumption rate when you are also producing more from your solar panels.

thank you. i will give them a call to see when they will update the account and see if that make a difference.

You are welcome. Let us know how it turns out for you.

Update: So our PSEG provider finished install and setup of their meter about a week and half ago. I still see my "self consumption" increase with solar production. Is it possible as solar production increases, that either inverter or battery backup draw more power and that is reflected in my consumption numbers? When production is at zero my usage is around 0.30w to 0.50w as production increases it goes higher and around near 10kwh of production is hits about 2.0kwh of consumption. it will only go down as production goes down. I have verified multiple times that there is no new devices or systems turned on. I tried to open a ticket with Solaredge but all they do is test inverter and say everything is working correctly. i tried to ask if it could be the IE meter with no response. i am now waiting on installer to give me a call to go over this issue. Hopefully this is just an APP issue and the export to SP is accurate.

This isn't your complete equipment list is it?

Solaredge SE10000H inverter

You must have an additional energy meter. And do you have an inverter with a revenue grade meter built in? If you provide the full model number of the inverter I can check it against SE's data sheet.

Also, you have a large inverter (10000W AC output). How is your inverter connected to your electrical system? If you had an electrical schematic that would help. Depending how your inverter is wired and how your CT's are wired, we might be able to figure out how to troubleshoot your system.

"When production is at zero my usage is around 0.30w to 0.50w"

Do you really mean 0.3w to 0.5w? Or do you mean usage is 0.3kwh to 0.5kwh?

I don't have a SolarEdge system but might be able to help given enough information.

Thanks,

Phil

yes sorry it 0.30kw to 0.50kw during a normal morning prior to Sun up. Once sun starts producing it climbs. At 10kwh of production it can hit 2kwh of consumption.

Here is a picture while there is not much solar production. I believe my battery interface that connects to the inverter has the import export meter in it. I don’t have a separate unit. The installer showed it to me on his last visit.

that model is BI-NUSGN-01

I just looked at your first 2 posts and correct me if I'm wrong. Your system as of the posting had been online for about 14 days and it's lifetime production is at 2.04 Mega Watt hours. Can't possibly be. They have a programming error on their end of how your production data is handled. I had the same issue with my system, the "dashboard" showing me to be generating and using way more than I was. Funny part was if I opened a different page of my system on the website the data was correct only the home page was corrupted. Numerous email exchanges with them were no help they insisted it was on my end (wrong Ct's, calibrated wrong, installed wrong, yada yada yada) I finally gave up, put in my own "old school" watthour meter to track production.
Low and behold 3 months later suddenly and without comment from Solar Edge the data moving forward is correct on the website and phone app. (they never did change the incorrect values for the first 3 months)

I agree I sent my installer a new screenshot today because as soon as my EV started charging my consumption into the house normalized as the majority of the production was going into the EV. when it was done charging the consumption to the house went back up to about 2kwh. As it got later in the day and productivity dropped the consumption dropped to normal amount. I’ve been watching this like a hawk and even know when fridge compressor kicks in to increase consumption but it never really goes more than 1kwh with fridge, washer, and TV.

Excellent that you and Mike 134 connected on this issue. I looked at the installation of the Backup interface and it looks pretty "fool proof" as far as CT's and energy meter goes. I can imagine one programmer's math error is causing hundreds of tech support calls.

Here is a picture while there is not much solar production.

Can you post the image of one day's production and consumption? At the same screen you captured, just scroll down.

My data was totally whack at the initial system installation. It alleged that my house consumed no power at all unless the sun was up. See the first graph.

It was a simple connection error -- swapping the L1 and L2 CTs as plugged into the energy monitor module corrected the issue.

I'm not sure if this is the problem you're having, but it's probably the simplest to create and to correct.
