Unofficial app for hybrid solar inverters that speak the Voltronic protocol: Axpert, Axpert King, Inverter King, MPP Solar, EASUN, PowMr, Must, Effekta and compatible models. Axpert King Flow Monitor connects to your hybrid inverter over Bluetooth and shows you, live, what the panels are producing, whether the battery is charging or discharging, what comes in from the grid or the generator, and what your home is using.
No account, no sign-up: the readings stay on your phone.
FREE
• Solar generation: live watts, panel voltage and current, when the sun started and stopped, and today's sun hours. The bar splits what comes in between the home and the battery.
• Home consumption: watts, inverter load, output voltage, current and frequency, and inverter temperature.
• Battery pack: percentage, voltage, charge or discharge current and power, today's peaks and the amp-hours left. The app works out the percentage by counting the amp-hours going in and out, not with the inverter's voltage formula, which is way off on lithium batteries.
• Grid or generator: estimated input power, generator load, voltage, current, frequency and the diesel left in the tank.
• Double-tap a card to see it full screen.
PRO VERSION
• History charts: tap the "+" on any card to open its charts by day, week, month and year, with one point per minute and the all-time peak.
• Runtime left: the kWh and hours your home can run at the current load, and how long until the generator has to start.
• Animated energy flow diagram: power moving between the panels, the battery, the grid or generator and the home, colored by where it comes from.
• Station mode and remote view: leave one phone next to the inverter publishing under a 6-character code, and watch your system live from another phone with internet, wherever you are. While the app is open the screen stays on, so the station keeps reading.
• Inverter settings (read-only) and generator settings: oil changes, running hours, tank and fuel use.
• No ads.

COMPATIBLE INVERTERS
Hybrid inverters that speak the Voltronic/PI30 protocol over Bluetooth, either with built-in Bluetooth (such as the Axpert King or the Inverter King) or with a serial Bluetooth adapter (HM-10, JDY and similar).
UNOFFICIAL APP
Axpert King Flow Monitor is an independent app: it is not made, sponsored or endorsed by the makers of those inverters. Brand and model names are used only to show which equipment it works with, and belong to their owners.
YOUR LANGUAGE
In English, Spanish (Spain) and Spanish (Latin America). The first time it follows your phone's language, and you can switch it instantly in Settings.
ADS AND DATA
The free version shows a banner ad; with Pro there are none. In the European Economic Area, the UK and Switzerland, consent is asked first with Google's form. Readings and history are stored only on your phone; they only leave it if you turn on station mode, and then they travel under a random code, without your name or email.
YOUR FEEDBACK
If you like the app or run into a problem, tell us in a review and we'll fix it as soon as possible.
