I'm working with a BlueSolar MPPT 75/10. I'm using the VE.Direct Protocol to read the register data via USB. Over VE.Direct, the BlueSolar is reporting my PV current and wattage as 0.0. The BlueSolar Mac app reports the same. My multimeter is reporting PV current at 0.04 Amps at 18 volts, making the wattage 0.72. The BlueSolar does agree on the 18 volts. The datasheet for the VE.Direct Protocol shows that current is reported in 10ths. Is the BlueSolar rounding down the current measurement to 0.0 from 0.04? The wattage is reported in 100ths. Why is wattage not reported as 0.72? Is the current being rounded down to zero before the BlueSolar multiplies voltage times current and thus making the wattage 0.0? Thanks.
