ph1800-monitor

Hybrid Solar Inverter monitoring script with Zabbix Template. Tested with GreenCell inverter (Must inverters should work too)

How to

This project was developed to run on a Pine64 board with ARM cpu. Running this on a Raspberry Pi should be no different. To run this on an x86 system you need to compile aquarat's must_inverter wrapper. I am using DietPi OS (but Raspbian, Debian, Ubuntu should work too).

• Get the compiled armhf build and put it in /mnt/dietpi_userdata/MonoInverter: https://github.com/aquarat/must_inverter
• Install mono-full and php-cli on your OS
• Connect your PH1800 inverter to your SBC with USB (get a shielded cable if possible, included one can cause problems)
• Enter the MonoInverter directory and check if the connection works: mono MonoInverter.exe (you should see a JSON object in return with values. If you see null as values, reset the inverter)
• Go one level up (/mnt/dietpi_userdata) and clone my repo: https://github.com/sandroshu/ph1800-monitor.git
• Enter the ph1800-monitor directory and make MonoInverter.sh executable: chmod +x MonoInverter.sh
• Set up a cronjob that runs this command every minute: flock -n /tmp/monoinverter.poller -c "/mnt/dietpi_userdata/ph1800-monitor/MonoInverter.sh" (Optionally you could create a systemd service that runs the MonoInverter.php script every x seconds, 15+s recommended)

At this point you have monitoring active and every parameter with its value gets written to /tmp/MonoInverter/* every time the script runs.

To get Zabbix monitoring working, follow these steps:

• Install zabbix-agent on your OS
• Configure Zabbix according to your setup (optionally install Zabbix server too if you don't already have one)
• Copy zabbix_ph1800.conf from my repo to /etc/zabbix/zabbix_agentd.conf.d/
• Make MonoInverter.data.sh executable in cloned dir chmod +x MonoInverter.data.sh
• Restart zabbix-agent
• Import zabbix_ph1800_template.xml to your Zabbix server as a template
• Add the template to the Host
• Check if theres data from the Inverter in Latest data of the host

Information on how to install and Configure Zabbix Server, OS packages and git can be found on a bunch of sites.

I still need more info to document the Inverter parameters better, it's not 100% yet and some are missing from the Zabbix template too.

Feel free to contribute to the project and add/correct these.
