dbus-mppsolar

DBus VenusOS driver for MPPSolar inverter or any compatible one.

What does it do?

After installing this to VenusOS. Venus will be able to auto-connect to inverters that follow MPPSolar protocols though a USB-Serial interface.

It will automatically spawn the inverter in a very similar way to Victron Multi inverters, and will support controlling the inverter trough VRM.

Install Instructions

Prepare Venus OS (optional):

You may need to install GIT and python by doing:

/opt/victronenergy/swupdate-scripts/set-feed.sh release 
opkg update
opkg install python3-pip git
pip3 instal mpp-solar # Not needed because this repo uses it as a submodule

Clone GIT & submodules on Venus OS:

git clone --recurse-submodules https://github.com/DarkZeros/dbus-mppsolar /data/etc/dbus-mppsolar

Now install the service to the VenusOS to allow starting it when needed:

cp -R /data/etc/dbus-mppsolar/service /opt/victronenergy/service-templates/dbus-mppsolar

Add the service to the starter rules, this will autostart the service on new USB-Serial connections with any compatible inverter. Modify /etc/venus/serial-starter.conf add a new service in the list of services, and add it to the default list of service handlers at the start (mppsolar:gps:...:vedirect).

Here how it should look like:

...
service mppsolar        dbus-mppsolar
...
alias   rs485           mppsolar:cgwacs:fzsonick:imt:modbus
alias   default         mppsolar:gps:vedirect 
...

What does this repo depend on

• Need velib_python for execution of the service
• Need mpp-solar to communicate with Inverter

What inverters are supported?

• Inverters that follow the PI30 protocol, or PI30MAX
• The rest, are not yet parsed, but feel free to implement the update()/change() functions for them :)
