The output current is twice as high.

Im using the mppt currently with a 12V/8.4Ah AGM Battery. I set FUGU_BAT_V 14.4 ( Cyclic Use Voltage is 14.4V-15.0V) in "charger.h" and in battery.h i set:

float detectMaxBatteryVoltage(float idleVoltage) { float voltageStep = 14.4f; // lifepo4 4s (3.65V) [1,2,4] float minVoltage = 10.f;

Now while using a variable power supply i get twice the output current. I have to set in main.cpp: sensors.Iout = (Iout_ch != 255) ? adcSampler.addSensor( { Iout_ch, Iout_transform, {2.0f, .1f, true}, "Io", true}, 30.f, ioutFiltLen) : adcSampler.addVirtualSensor([&]() { if (std::abs(sensors.Iin->last) < .05f or sensors.Vout->last < 0.1f) return 0.f; return ((sensors.Iin->last * sensors.Vin->last * conversionEfficiency) / (sensors.Vout->last)/2); }, ioutFiltLen);

Dividing the return by 2 for the virtual sensor.

Obviously im missing something here... Since youre using 28V Battery System maybe its related to this?

Which commit hash are you working with? git rev-parse --short HEAD

Is conversionEfficiency a local variable? If so, replace adcSampler.addVirtualSensor([&]() with adcSampler.addVirtualSensor([]().

I remember there was a bug with local variable conversionEfficiency being referenced by the virtual sensor function, which caused access to an invalid stack address.

I will check when I’m back home. I’m On-Site for a couple of days. I’ve installed everything to my wind turbine and it did work. You can hear it through the generator when tracking is ongoing ;-) I need to reinforce my mast or install some tie-downs first. I really underestimated the forces…
