Notice

Protection (Current Sensor Anomaly):
This issue occurs when using inverters due to uncertain current direction, resulting in an alarm. It does not impact the normal BMS functioning.
Inverters can cause fluctuations between charging and discharging in variable sunlight conditions, producing this anomaly.

Sine Wave Inverter Behavior:
Inverter current follows a sine wave, varying from zero to peak in each cycle. A pure sine wave inverter does not draw a constant current, affecting current readings.
Average current meters provide near RMS current, but readings may fluctuate due to waveform shape.
Over extended periods, the BMS accurately calculates amp-hours based on averaged readings.
