DeltaPVOutput optimised for WebSolarLog www.websolarlog.com

A python scripts to use RS485 Serial from Delta Inverter to PVOutput.org. It is will work with multiple delta inverters and is compatible with WebSolarLog (http://www.websolarlog.com/)

DeltaInverter Module has two major functions:

Generation of Command Strings to be sent over RS485 to the inverter

Parsing of response strings received from the inverter, this is done in two forms:

1. Obtain the raw values using getValueFromResponse

2. Obtain a formatted response using getFormattedResponse which will contain the instruction/value/unit tuple

A list of instructions known is also in the module, obtained from https://code.google.com/p/pvbeancounter/issues/detail?id=251

DeltaPVOutput - simply queries the inverter and posts the result to PVOutput.org with no arguments.

You will need to insert your: • PvOutput systemID

• PvOutout API Key

• Serial port eg /dev/ttyUSB0

• Port speed eg 19200

• Inverter Number eg 1

in config.ini to work without arguments. If you have multiple inverters simply create a second system configuration. Eg

[Inverter1]

SystemID: 00000

APIKey: 0000000000000000000000000000000000000000

Port: /dev/ttyUSB0

PortSpeed: 19200

InvNo: 1

[Inverter2]

SystemID: 00000

APIKey: 0000000000000000000000000000000000000000

Port: /dev/ttyUSB0

PortSpeed: 19200

InvNo: 2

This example layout can be found in config.ini.example

Run via crontab to poll periodically

WebSolarLog

This allows WebSolarLog to run DeltaPvOutput

1. Follow instructions installing WebSolarLog (http://www.websolarlog.com/index.php/installation-manual-for-websolarlog/)

2. change to WebSolarLog installation directory (eg /usr/share/nginx/www/websolarlog)

3. change to the devices directory (eg ./classes/devices)

4)clone DeltaPVOutput into DeltaSoliviaPy directory (eg git clone https://github.com/bprice/DeltaPVOutput.git DeltaSoliviaPy)
