    Additional Information On Solstus

    MFC Solstus Logo

    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 Voltronic type inverters such as Axpert King, MKSII, Mecer(Branded) and Kodak(Branded) with support for Pylontech, Narada and other batteries.

    The Solstus software runs on a Raspberry Pi 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 Voltronic 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

    MFC Solstus Monitor C++

    Solstus, It just works

    With an active development cycle and useful feedback from our clients we deliver monthly improvements and features. Solstus is compatible with the Raspberry Pi model 3 B+ but we recommend the new Raspberry Pi 4 2gig models or better for a super smooth experience. Updates are made available for free to all clients.

    Developed in C++ for speed, Based on Linux as the foundation, we built Solstus upon a rock solid, tightly integrated and optimised platform. Using the latest technologies, we are always expanding and adding new features which you get completely for free.

    MFC Solstus Pylontech Support Icon

    Pylontech Lithium Ion BMS Fully Supported

    Full support for Pylontech Lithium Ion and Narada BMS Battery integration. Solstus has a section where you can view detailed information about your batteries, Per unit in the stack. Its volts, amps, temperature and even the health and cycles.

    Typically, these types of smart batteries are a much better investment, long outlasting conventional Gel or Lead Acid type batteries. While delivering efficient performance over years. Solstus was specifically created to work seamlessly with Pylontech. But we also offer support for Narada.

    MFC Solstus Monitor Notification Icon

    Get Notified

    Solstus can push email notifications to you when events occur so you are always in the loop, even when you are away. We offer a detailed log of events that happened throughout 7 days that you can view at any time, locally or remotely.

    Not only does Solstus monitor and send notifications about your power status but also notifications about the Raspberry Pi and its status. Should it run hot or if the SD card free space is running low you'll get notified.

    MFC Solstus Monitor Charts Icon

    Keep track of your power usage

    Solstus comes with a very friendly interface to track your power consumption for up to a year. We've taken out the hassle of complicated formulas and worked it all out for you. Exporting to .CSV is also available so you can do your own plotting.

    You can choose the time period from the last hour, up to a year to view power data in detail.

    MFC Solstus Monitor Sun Icon

    Run your power your own way

    Solstus have intelligent modules build in to manage operation mode based on the time of day or SOC percentage.
    You can of course use both of these modules together to manage your power, your way. With Solstus you can switch the Power mode at any time using our secure setting section. Choose form Utility, Solar then Battery mode to Solar Utility then Battery or go off-grid with Solar, battery then utility mode.

    MFC Solstus Monitor Raspberry Pi Icon


    Solstus will not only give you feedback on your Voltronic inverter and batteries but will also give you critical event feedback on your Raspberry Pi Before things go south you will know about key interest points. Making sure you are always informed on the state of the solar system.

    Solstus is supported on Android and iOS, Linux and Windows. It doesn't matter what device you use. If it has a browser you can use it to track your Solar system's stasis tics and data We have even seen some clients use their Smart TV's to view out dashboard right from the comfort of their couch.

    MFC Solstus MQTT Icon

    Automation with MQTT

    Solstus now includes support for sending values via the MQTT protocol to a MQTT Broker such as mosquito which is included by default.

    Mostly used for home assistant integration but for those that want to use it for more advanced control with other supported hardware Solstus can be configured to send predefined topic to a broker, these values can the be used to trigger or toggle other devices on your network.
