WattPlot™ ACKcess 6.0 Field Test

A number of long-time WattPlot users and testers have expressed an interest in participating in field testing new WattPlot releases.  This has worked very well for our previous major launches, so we now organize field tests for all significant updates and new product releases.

The latest software release entering field trials is the first of a new generation of tools...

WattPlot™ ACKcess 6.0

Any WattPlot users out there who experienced the leap forward from WattPlot 4 to WattPlot 5 know the huge leap forward that our software suite took after a decade of monitoring systems around the world.  Well, we've done it again!

WattPlot 6 begins with an entirely new foundation for our software, based on Modbus technology and a new strategy of graphic interface.  Among other things, this will mean less configuration - more plug-and-play, and the addition of support for other manufacturers and other modbus-compatible devices.

Our first WattPlot 6 tool is a new one, called WattPlot ACKcess.

ACKcess Home Screen

An early version of the ACKcess Home Screen.
Hovering the mouse over any component brings up the tool strip (as shown on the central inverter),
giving you access to the relevant History, Information, Tools, Settings, and Alerts.
Hovering over the bottom right area shows a tool strip for the whole system.

Here is some of what it can do so far:
  • Access the display, controls, system data, and system settings, using TCP/IP via an IP address - i.e. from anywhere there is internet, AND on local networks where there is NO internet!
  • Automatically configure itself when it is connected to a MATE3, MATE3S, AXS Port, or MidNite Solar Classic.
  • Compact animated graphical display, similar to WattPlot VisualMATE (and OPTICSre).
  • Click anywhere for relevant Settings, Alerts, and History.
  • Built-in REactor function, allowing you to easily extend the programming of your entire system.  Define triggers, based on real-time data, time-of-day, and more.  ACKcess can then automatically alert you to conditions of interest, or even change settings on the system in response.
  • Provides Advanced Generator Control which exceeds anything available from OutBack.
  • Call up line and bar charts OR summary numbers, by day or by hour, showing the parameters that you select.
  • Download data logs directly from your AXS Port SD Card (not MATE3), summarize the data, and back them up locally.
  • Automatically update data log downloads on restart (AXS Port only).
  • User-friendly access to many settings on your Outback system (with full descriptions) - more being added all the time.
  • Navigate the screens using forward and backward buttons.
  • View full Events and Maintenance logs.
  • Issue device commands such as for Bulk and Equalization charging.
  • View snapshot bars (presently for inverters and charge controllers), just like the WattPlot Monitor program.
  • Leave the program running to control your system (based on your easy programming), text you alerts, etc.
    Turn the program off, but keep logging all data on an SD card, and let ACKcess turn that data into information later.
  • Monitor non-OutBack equipment as well (if it has a modbus interface), including all SunSpec-compliant inverters.
  • Click anywhere for relevant Tools, Information, and more.

ACKcess Home Screen

One of the many Inverter Settings screens.
Note the valuable help text that is displayed whenever you click on a setting.
Default values are in white, altered values are in yellow.
You can even use your mouse wheel to scroll through values.

And here are some of its planned features:

  • Drill-down from overall system picture to daily summaries, plots, and spreadsheets.
  • User-friendly access to over 650 settings on your Outback system (with full descriptions).
  • Full command and control capabilities - you can do anything you could do from the MATE3, and lots more.
  • Eventually, everything that our flagship WattPlot Monitor PRO can do, and much more!

We are now at the ALPHA testing phase for WattPlot ACKcess.  That means that we are still in the very early stages of product development, and not everything is turned on yet.  We want to move methodically and make sure that we get the new foundation right before we activate everything for a production release.

We also have some very specific requirements for our initial testers:

  • You must be an existing WattPlot user, with WattPlot Monitor, VisualMATE, or NetMATE installed (5.0 or higher).
  • You must have a MATE3 running firmware 003.009.000, 003.011.000, or preferably 003.015.005.  (Other 003.015.xxx releases have too many problems)
    You must have an OutBack AXS Port device running 003.015.001 or later.
  • The ability to capture session fragments with a screen cam would be an asset.
  • Patience is a must.  A willingness to contribute new ideas for features is a plus.
  • Preference will be given to sites that offer diverse configurations from other test sites.
  • Please contact us ahead of time, letting us know what system components you have.


Follow the numbered steps below for copying the new program into your existing WattPlot program folder, and run it from there.

Watch for issues, try things out, and watch here for program updates.

Please email us at WattPlot and let us know that you are participating in this field test, and we'll let you into the inner circle of people being informed of the latest updates and progress!

Reporting Bugs or Suggestions

Our existing WattPlot tools have a phenomenal amount of error handling and data capture processing built right into them.  This is not the case for WattPlot ACKcess, since we are in the midst of reworking how errors are handled and reported.  It is a an extremely sophisticated piece of software, working in a huge variety of live data environments, so bugs are often very hard to track down and/or reproduce.

It is therefore imperative that you give us as much information as possible when you encounter a problem.  Our best testers use screen cam video software to show us exactly what happened, but not everyone will have that.  It is therefore critical that you describe exactly what you were doing when the issue arose.  WattPlot ACKcess will sometimes suggest data files to include in the email coming to us - probably best to go with the suggestions as a minimum!

Updates & Notes

Latest Update EXE

You do not need to un-install or re-install WattPlot ACKcess to get these updates.  Most updates are done by simply downloading a replacement ACKcess.exe file.

  1. Click on the "Download now" button below.

  2. Depending on your browser, click the "Save As", "Save", or "Copy" button, and then direct your system to save it in the folder where your WattPlot EXE files reside (which is typically c:\Program Files (x86) \WattPlot).

  3. If it tells you that the file already exists, and asks if you want to overwrite it, click Yes.

  4. If you are using a MATE3, you will need to connect it to your router using a network cable.

  5. On the MATE3, go to Settings / System / OPTICSre and set BOTH OPTICSre and SunSpec Interface to Enabled.

The latest version of WattPlot™ ACKcess is:  (03 April 2018)

This is a replacement EXE, not an installation program.
Do NOT attempt to RUN this program from the web site.
See the numbered steps above.

Known bugs, limitations, and incomplete functions - as of 27 March, 2018:

  • Sometimes, when changing screens etc., the ACKcess main screen acquires scroll bars and doesn't show the whole screen. We don't know why this happens yet, but we are working on it. Sometimes minimizing and restoring the screen clears it up.
  • It would appear that the MATE3 firmware does not handle control of a charge controller AUX port correctly - perhaps depending on the state of the actual charge controller display screen - although this may have been fixed in
  • We are still trying to resolve FTP issues with the MATE3 SD Card.  This appears to be a MATE3 firmware issue.  ACKcess works great using FTP on the AXS Port SD Card.
  • The TCP Server function has not yet been implemented.
  • Some REactor response actions have not yet been implemented.
  • The pen-plots have not yet been implemented.
  • Everything else has been implemented and is fair game for testing.  NOTE that many of these functions may be carry-overs from WattPlot 5.  It is awesome when these still work without any additional effort, but not surprising if they need some tweaking for the new foundation.  Do let us know what miscellaneous things DO work and which DON'T.

We can't promise you anything for helping out - except an earlier release date, however if you ask some of our previous testers, they'll tell you that people who give great feedback during these trials are often rewarded for their patience and diligence!  Who are these people?  Well you'll find a list of the hardest-working ones by double-clicking on the WattPlot icon in the Help...About screen.  (Your small reward for reading this far!)

Thanks again!  And enjoy being on the leading edge!
