The development of a three-phase Axial Flux Permanent Magnet Synchronous
Generator (AFPMSG) with a cross-flow turbine for a pico-hydro system intended to supply
electricity to a charging station in off-grid locations is presented in this study. In comparison
to traditional pico-hydro configurations, the system seeks to increase sustainability and
efficiency.
The AFPMSG is intended to run at 700–950 RPM, 500–550 W, 15–30 V of voltage,
and 5–10 A of current. Voltage, current, power, and energy consumption were tracked with
a real-time monitoring system that used the PZEM-015 module. Run-of-river flow was used
to test the system in the field in Daraitan, Tanay, Rizal.
The AFPMSG's feasibility for renewable energy applications in low-head, off-grid
water sources was confirmed by the results, which showed that the system efficiency peaked
at 88.83% under overcast conditions. Furthermore, the system maintained consistent
performance in charging 12V lead-acid batteries with 76Ah total capacity, sustaining a net
remaining charge of 94.44% over 24-hour day/night operation.

This study demonstrates the potential of AFPMSG-based pico-hydro systems as a
clean, reliable, and locally manufacturable solution for rural electrification, particularly in
geographically isolated communities.
