Solstus Solar Monitoring Software For Axpert Inverters

What is Solstus all about

Solstus is Solar monitoring software that was developed to be easy to use and understand, stable and reliable. Compatible with Axpert type (Voltronic) inverters such as Axpert King, MKSII, VMIII, Mecer(Branded) and Kodak(Branded) with support for Pylontech LiFePO4 batteries.

The Solstus software runs on a Raspberry Pi or Linux Ubuntu as a service and collects data from your inverter and batteries.
To view the Solstus Solar dashboard you can either connect an HDMI screen directly to the Raspberry Pi itself or, use any device that has a browser to load the HTML dashboard up over local LAN or even the Internet. This gives you incredible flexibility no matter what device you use or where you are in the world. Solstus uses a web based GUI to communicate with the Solstus service application allowing you to view, and change inverter settings from within the Solstus Web App. From Smart Phones to Tables, even Smart TV's and Computers, all devices are supported. Android and iOS too.

Our installation is as simple as creating an account, purchase a license, downloading the image file and flashing it to an SD card. Connect the Raspberry Pi to inverter then boot up. Navigate to the Raspberry Pi IP Address and from there just complete the activation process.

Multiple devices can be used to view your solar dashboard and your solar status at the same time over Local network or remotely via secure provided VPN which is... Completely free of charge.

Note: Pylontech and Narada require additional cable hardware for communication with Solstus
