Today, we are testing how to convert a 3.2V low-voltage battery cell into 220V AC power. And easily drive high-power fans. We are using an MPPT inverter equipped with a coulomb meter to monitor current changes in real-time. At the moment the fan starts, the coulomb meter displays an immediate doubling of the current. This is a typical characteristic of inductive loads, where the starting current is much higher than the operating current. However, thanks to the efficient inverter, even a small low-voltage battery can stably output 220V AC power. The smooth operation of the fan without any resistance proves the power of efficient energy management, even low-voltage batteries can provide high-performance output
