@meetyg It did install the drivers in the background on windows 11, still kept searching in the software though (Inverter is on), I am using a printer cable to connect from the inverter to the PC. Is this correct?
@AlexanderR I bought my MUST PV1800 mppt inverter and battery from solarway last week, they are legit and the cheapest I've seen so far, after plenty research.
Any link for a driver I can download to make this work for me in SolarPowerMonitor, mine just searches and searches and does not find my Must PV1800 MPPT inverter
