FDD is a simple service that reads from a Fronius web API and delivers the data to an InfluxDB.

Instructions

This application can be run standalone from Linux or Windows command line.

If not possible to install as a service you could schedule i to run using cron on linux and Scheduler on Windows.

Before starting, verify settings in config.json. That file must lie in the active working directory, that is usualy in the same directory as the binary unless explicitly changed.

Run as a service

Commands avaliable to control service:

• start
• stop
• restart
• install
• uninstall

Must be run as an administrator.

Example:

fdd.exe -service install
...
fdd.exe -service uninstall

What is logged

Most values for GetPowerFlowRealtimeData, per site and inverter. Most values for GetMeterRealtimeData, per instance found under Data.

WLS installation av senaste versionen av GO

Install Binary Distribution Let’s say we wanted to get the latest version, we would have to install the official binary distribution.

We first go to https://golang.org/dl/ and select a compatible release according to our OS

go1.11.5.linux-amd64.tar.gz Let us open our terminal download our file and extract it in our current directory.

wget https://dl.google.com/go/go1.11.5.linux-amd64.tar.gz
$ sudo tar -xvf go1.11.5.linux-amd64.tar.gz

tar : stores/extracts files from the archive x : extracts the file from target v : verbosly list files process f : use archive file Now we have a folder /go on our current directory. Let us move it to /usr/local/

sudo mv go /usr/local

Set Enviroments Our last step is to add our global variables on our .bahsrc or .profile file.

sudo nano ~/.bashrc

scroll down and add these to your .bashrc profile

# Go Global variables
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

To save it Ctrl + o, and to exit nano Ctrl + x

update current session

source ~/.bashrc

Check

go version
// go version go1.11.5 linux/amd64
