  • 1.  Application for individual panel info

    Posted 03-02-2023 09:45 AM

    Hello! 

    New to this community.  I just got my system installed the end of January. 

    CertaSun is the installer and equipment provider, and I am satisfied with just about everything so far. 

    The only thing that is not where I would like it to be is the app that they developed to monitor the system.   It's, like,  90% of what I would like.   

    The only thing that I feel is lacking is the ability to see how individual panels are performing.  After speaking with a rep from the company,  that is not something available at this time. 

    Does anyone know of a 3rd party application that I can use to monitor that information? 

    Thanks

    I am guessing you have micro-inverters..??..

    If so make and model..

    EDIT:

    To give more detail, the solar panels themselves are pretty much irrelevant when it comes to communication detail. If you have micro-inverters, those inverters are where the communication interface is located. There are several ways it can be done, usually through what's called a "gateway" coms unit. 

    SO the possible app you seek would have to recognize this "coms" unit", etc..

    SO to help you, make and model of these micro-inverters and gateway if exists, are needed....

    I know they are enphase micro inverters,  but I don't have the model right now.  Trying to verify what was installed.   

    Still new to this, so my apologies for not having it right on hand.   I'll get that info here as soon as I track it down

    Enphase offers a gateway device (I think the app is called Enlighten) that communicates with each microinverter and gives lots of data. I have their M215 micros (pretty old tech) on my barn roof. Screenshot from today (not a good solar day here) attached and more available at https://enlighten.enphaseenergy.com/public/systems/Hctc107221

    That's a good start, enphase micro Inv's. As mentioned, usually there will be a gateway that has coms availability. This would usually be located next to you main breaker box or close by for the attachment of CT's (Current transformers) that allow for power readings, etc.. Your local Wi-Fi would then communicate with that. 

    This URL to enpahse gives you a brief overview of how the systems work.

    I did load the enlighten app on my phone, but I can't "connect" to my system because it's not enphase equipment and not an enphase installation.

    Certasun uses enphase inverters,  but it is a sunpower system (the control box? ).

    Mark,

    I think Certasun or Sunpower may be the only ones who can help you get insight into solar module-level data for your system.  I do not install sunpower, but it looks like there should be that capability in the product since they use microinverters in the Equinox system.  No 3rd party system is going to be able to communicate with the microinverters to get module-level data from them.

    Enphase systems (true enphase branded) provide that insight as does SolarEdge with their Smart DC-DC converter optimizers, so if SunPower does not currently provide that insight, I would expect it is just because they have not developed the solution yet and they will offer it soon or they will risk losing business to SolarEdge and Enphase.

    Good luck.

    Hi Mark: You can see a screen shot capture for a Google query for Enphase CT's. 
    CT's look like plastic donuts that are placed around the main wires in your main breaker box, usually. 
    I am not going to get into a "blind" guessing contest on what is or is not in your system for its function. 
    CT's are the "standard" for measuring power "travel" on most solar installs and power meter devices.
    What can happen on these systems is installers can pick and choose different equipment to assemble the total system deliverable. You should have in your possession an exact equipment list for you system install, which should detail out the EXACT equipment used for your install.
    Unfortunately a PV solar system is not quite as simple as a microwave oven for the end consumer regarding information and understanding. You are going to have to get your hands "dirty" a bit to find out exactly what you have and where it is. IF you have an Enphase gateway type of device, I would think an Enphase app would communicate if the configuration was correct.
    But to be honest, the installer SHOULD be able and willing to help you with this and any questions you have for a proper service after the sale cooperation. Without pictures and exact equipment list models it is hard for us to know precisely what to tell you to get you operational. But hopefully some of the info we've given you will help.

    Fyi there are no CTs in my Enphase system.  Works by some sort of powerline communication between micros and gateway.  Wifi provides data to the app on your phone, tablet or PC, and connection between gateway and web (edit) is hardwired.  App totals the energy produced from all the micros so noCTs are needed.  

    Photo of my 2 gateways attached.  Note lower gateway indicates 134Mwh lifetime generation but most all of that is from a previous installation.- I got it on ebay.  Also lower is dedicated to when the lower array is AC-coupled to another system on the barn so is not in service in this photo.  Only AC-coupled during grid outages.

    Hope this doesn't complicate things.
