Re: Photovoltaic/solar systems monitoring

@Neil, Post some info about your setup and we'll see if your hardware is/will be supported. You can find the mailing [email protected]://www.solarspy.net/solardev. I think I could post an update on what's going on with the project The project is not progressing blazingly fast as this is a side project. Nev...

Re: Photovoltaic/solar systems monitoring

Hello shacent, Although my solution would be suitable for your situation, it needs customization per case, and this might be a sticky point because it's a C++ application which is not suitable for beginners. Nevertheless if you wish to have a try, you can find the code on a previous post. I would su...

Re: Photovoltaic/solar systems monitoring

Hi, You are lucky because fronius inverters are already supported very well. Right now the probe extracts the following info: power, currentAC, currentDC, voltageAC, voltageDC, frequencyAC, Phase1Current, Phase2Current, Phase3Current, Phase1Voltage, Phase2Voltage, Phase3Voltage, DailyEnergy, TotalEn...

Re: Photovoltaic/solar systems monitoring

probe project was published as open source: https://github.com/alxnik/fpd If someone messes with the code or makes any changes, I would be happy to hear about it, as it has some known bugs that haven't been fixed yet.

Re: Photovoltaic/solar systems monitoring

Hello Very cool project (even without understanding dutch). It's funny how many people in the world have the same problem and develop for it independently. Thanks for the tip, I have already researched other projects and will look into them more as soon as I have access to an SMA inverter. Given tha...

Re: Photovoltaic/solar systems monitoring

anwmalos, Yes, the simple probing should not be a problem. I do have one question though. The outback mate communication manual says that the serial port on the mate is optically isolated from the system, and the power to the port is supplied by driving the DTR high and the RTS low. The simplest so...

Re: Solar monitoring?

Hello, I have no problem connecting usb2serial on the raspberry pi, it seems strange that you mention it. Actually, right now I have one PL-2303 converter connected, with an application banging bytes out the serial and there seems to be no problem. (FYI I have the latest raspbian installed) Neverthe...

Re: Photovoltaic/solar systems monitoring

To everyone who wants SMA support: I need one lucky volunteer who will have a raspberry pi and a bluetooth dongle (will discuss on which one later on) powered on 24/7 and at my disposal so I can connect through SSH and start developing/testing for SMA inverters. No raspis will be harmed during the d...

Re: Photovoltaic/solar systems monitoring

Hello everyone, There is interest in this project for devices I didn't initially plan so I am not sure if I can personally commit to develop/integrate these devices as I am more oriented to on-grid PV inverters. Nevertheless, I'm in the process of finding a version control hosting solution (self hos...

Re: Photovoltaic/solar systems monitoring

@TarjeiB Cool project! I checked your inverter and the company doesn't have any specifications about the communication. It is a bit strange that it mentions TTL232 and not RS232, be careful when you test it because if it uses TTL levels it might not be a very good idea to connect it to a standard se...

Re: Photovoltaic/solar systems monitoring

Hello, I'm happy to hear that. Please post some details about the inverter brand you use in order to see if it supported (probably not). If not then you probably have to give me access to your raspberry in order to develop for it. If you want, you can subscribe at the mailing list I posted in a prev...

Re: large scale sensor input

Ok, I think you convinced me to continue with a full handmade solution. Some questions though: 1. There are many different capacitor technologies. Which one is the best for this application? Is more expensive better? I never really undestood the differences between them. 2. Would it make sense to ad...

Re: RasPiComm - RS-232, RS-485 and RTC

Hello

Very cool project! Have you converted the GPIO pins to 5V for the input/i2c or are they still 3v3?

Re: large scale sensor input

Thanks for the feedback. I should have mentioned that although this is a 'personal' project and not a commercial product, I am trying to replicate an industrial installation. My budget is not exactly hobbyist as I have some backing in order to make it work (let's say I can get in the 4 digit budget ...

large scale sensor input

Hello, I have an automation project that needs input from 54 sensors and output to 36 relays. Although this is normally a job for a PLC, I hate these things and the ladder logic they use so I decided to concentrate my efforts on making something with the raspi. Now to my problems: I need to get inpu...

Photovoltaic/solar systems monitoring

Hello everyone, For the past year or so I've been developing a tool to monitor solar panel installations. Until now this was a personal and not published project. Now it's in a good enough state to open up a little. The project started with different embedded linux systems, and I was expecting raspi...
