Links to help me monitor my Zeverlution PV converter locally

Posted by jpluimers on 2018/12/18

Since it’s my data, I’d rather be in control myself, so here are some links that will help me going around the Zevercloud solution I posted about yesterday.

Some other interesting links of software supporting Zeversolar devices:

Note that does have native ZeverCloud updating using the ZeverSolar API key:

But these might help me:

Registering your Zeverlution device in the Zeversolar cloud

Posted by jpluimers on 2018/12/17

If you have a Zeverlution PV converter, the easiest to get at the data is through the Zeversolar cloud.

The included documentation does not contain web browser registration instructions, only Android/iOS app.

So here we go:

  1. Create an account at [WayBackZeverCloud – Login: click CREATE AN ACCOUNT, then
    1. Fill in these fields:
      • Email
      • Password
      • Re-type Your Password
    2. Check the I agree to the Terms of Service & Privacy Policy box
    3. Press SUBMIT button
    4. Wait for your confirmation email to arrive
    5. Confirm your account
    6. Logon
  2. Follow the link, then
    1. Fill in these fields:
      1. Monitor SN (this is actually the MAC address without seperator; it starts with EAB961 which is an unknown OUI)
      2. Registry Key
    2. Press the Continue button
    3. Fill in these fields:
      1. Plant Name
      2. Installed Capacity (note the unit is not Wp, but KWp, so multiply the # of panels by the Wp of the panels, then devide by 1000)
      3. Commissioning (date in YYYY-MM-DD format)
      4. Company/Organization
    4. Press the Continue button
    5. Fill in these fields:
      1. CO2 Avoided Factor (the unit is Kg/KWh; For The Netherlands get it from [Archive.isLijst emissiefactoren | CO2 emissiefactoren under ELEKTRICITEIT)
      2. Yield Factor (the unit is Currency/KWh where Currency is from field 3; get this from your local energy supplier)
      3. Currency
      4. Timezone *
    6. Check the Automatically adjust clock for Daylight Saving Time box
    7. Press the Continue button
    8. Fill in these fields:
      1. Country
      2. State
        1. Since this field could not be filled in for The Netherlands, I changed it using the Chrome Developer Tools having one option value: <option value="0">N/A</option>
      3. City
      4. Street/No.
      5. Zip Code
      6. Longitude
      7. Latitude
    9. Press the Save button

Note that the 2.0.2 version of [WayBack] ZeverCloud – Apps on Google Play does not work on Android Oreo.

Via internal Zeversolar channels, I got 2.0.2 development version Android works on Oreo – which despite the same version number, does work.

The new Google Maps/Earth satellite imagery allows to count our solar panels…

Posted by jpluimers on 2016/07/01

I checked our home using the recently improved Google satellite imagery: from Google Earth you can get better detail than from Google Maps.

You can even count our solar panels and see one is misaligned after a storm (a few days after this image was taken I managed to re-align that panel).

13 PV panels and one hot water panel lowered our energy bills for more than EUR 1000/year.

At 20160703, we had the highest peak power this year so far: 2424 Watt. It was for just a moment, but still (:

Hooking up a Sunny Boy 2500TL to the net

Posted by jpluimers on 2016/01/22

Out of the box, the BlueTooth equipped Sunny Boy models (the non network connected ones) can be monitored from your PC using the SUNNY EXPLORER software. But that has quite a few drawbacks:

  • The software is Windows-only.
  • It is not network connected.
  • The Sunny Boy aggregates historical data, so after a short while you loose the details it aggregated from.

There are scripts and apps that to download data via Sunny Explorer or directly over bluetooth and even export it to a site that collects and publishes PV statistics. They even have a nice region donut about world wide performance.

Some ways to do this:

Note: PV BeanCounter understands the Currentcost EnviR power meter, and the Currentcost Optismart works with Landis+Gyr ZME120ACd (and many other power meters too). Which means I can use PV Beancounter to watch my power consumption as well.

Cloud based Sunny Portal

There are two ways to connect to the cloud based SMA Sunny Portal. There are is an Android app and an iOS app connecting to the portal

Easy way:

  1. Get a SMA Speedwire network interface Webconnect module (Europe: model SWDM-10, USA: model SWDM-US-10)
  2. Connect to the Sunny Portal.
  3. Register your Sunny Boy using the PIC and RID identifiers on your network interface module.

The cool thing: all Sunny Boy equipment produced from October 2014 up come with Webconnect; too bad by SB 2500TL ST-21 was just a few months too old. If you live in the USA, the even younger and one model bigger models 3000TL and up have now have Secure Power Supply.

Slightly more difficult way: more expensive, superseded by the easy way.

  1. Get an RS-485 interface (for Europe: model DM-485CB-10, for USA: model DM-485CB-US-10).
  2. Get an SMA WebBox module (for Europe: model SWebBox-BA, for USA: model SWebBox-BA-US).
  3. Connect the SMA WebBox to the Sunny Portal using the Sunny WebBox Assistant (now called SMA Connection Assist).

Note: WebBox should be able to do ModBus too.

Do it all yourself without the cloud

Then there is the do it yourself way that gives you more insight (not just multi-string aggregates).

It’s also the hard way using the built-in BlueTooth and a stack of software to do it yourself.

There are a couple of choices to get started software wise:

I got most of the above from Best way to monitor SMA SunnyBoy inverters? – Solar Panels – Solar Panels Forum.

For instance you can use SBFSpot for connecting to on PV generated power: – share, compare and monitor live solar photovoltaic output data

Source: PVOutput supports WebBox out of the box, but for WebConnect you will have to do a bit more work.
