S10history

This program reads historical data from a S10 solar power station manufactured by E3DC and prints it to standard output.

Reports include:

  • Energy that was feed to the battery
  • Energy taken from battery
  • Energy produced by solar panels
  • Energy feed to the power grid
  • Energy taken from the power grid
  • Energy consumed by your house

Features

  • Read the sum of a Day, Month, Year
  • For Day you can also list an average power (not energy) per 15 minutes
  • For Month you can also list a daily energy report
  • CSV output for better parsing
  • PERL program to feed the output to a Mysql database
  • Scripts that show some usage

Prerequisites

  • RLOG library
    This program uses the RLOG library for debug and error reporting. If you do not want to use the RLOG library, you will have to replace all rWarning, rError, ... calls with a printf call
  • RSCP protocol setup in your S10 solar power station
    Please refer to the documentation provided by E3DC
    Needed: login username; login password; AES secret
  • Linux like OS with a gcc
  • Network connection to your S10 solar power station

Usage

To use the S10history script you should first store the passwords in environment variables:
export PW="your login password"
export AES="AES secret shared with S10"
user="mys10username"
ip="IP addr of S10"

Reading one paticular day (2017-02-17):
S10history -u $user -P PW -A AES -i $ip -y 2017 -m 2 -d 17

Read only the sum of that day:
S10history -u $user -P PW -A AES -i $ip -y 2017 -m 2 -d 17 -b

Read the sum of yesterday:
S10history -u $user -P PW -A AES -i $ip -d -1 -b

Read the Month and all days of that month:
S10history -u $user -P PW -A AES -i $ip -y 2017 -m 2

Read the sum of one year:
S10history -u $user -P PW -A AES -i $ip -y 2016

Put all days of one year into a Mysql database (please fill the scripts with your values):
examples/getYearperDay.sh 2016 > Year2016perDay.txt # reads all days to file
./S10toMysql.pl -dbname=myDBName -user=mySQLUser -password=PWofSQLuser Year2016perDay.txt
use the file to fill the database

Issues

A lot of values, reported by the S10 solar power station are off by some percent. If you find a flaw in my calculations please report. I am more than happy to correct that.

  • The power values of a day are inaccurate. They do not match with the WUI values
  • Some of the day values in monthly report are incorrect
  • The sum of all days do not match the sum of a month
  • the sum of all months do not match the sum of a year

History

07.2017 added switch so that UTC can be used instead of local TZ S10 uses UTC only for time; did not really help with accuracy 02.2017 Initial version
