[havoc]

I don’'t see how it explains, created separate topic, with some additional information:

AC component in inverter DC voltage

Multiplus II GX 24/3000 Redodo 100Ah 24V Lifepo4 battery. AC component at DC side detected when charging or discharging. Measured current with 2 pair of clamps similar values, also BMS of the batterie shows that current direction changes. With no-load with DC current 0,55A measured AC current is around 2,6A. Here oscilloscope picture for voltage AC component: [image] When charging battery with lab power supply (10A) no AC component detected.
