MPPT Volts to Current Conversion
My buddy picked up 6 300 watt panels today - because he wants to be able to feed his ravenous Starlink - without running the generator. The starlink uses 190 watts of power at 120v - it's a pig for p...

The watts to the battery get clipped about 10% to 15% to the battery voltage for the voltage conversion.
So in perfect conditions (that never exist) 1800 watt produced is maybe 1500 watts to the battery or over 100 amps at 14 volts. make sure the controller can handle the amps and volts (Voc) of the string of panels. The MPPT controller will also self limit to the output rating spec. A 30 amp MPPT will only put out 30 amps.
BTW at 30 volts and 8 amps the panels are closer to 240 watts. And voltage will drop some as the power begins to flow. Reality could be closer to 200w panels.
