This paper presents the modeling, design, and implementation of a rapid prototyping low-power solar charge controller with maximum power point tracking (MPPT). The implemented circuit consists of a 60 W photovoltaic (PV) module, a buck converter with an MPPT controller, and a 13.5V-48Ah battery.
When choosing a solar charge controller, you should consider the size of the load concerning how many amps the charge controller can handle. Most PWM controllers are better suited for small PV systems, handling small loads of up to 240W and operating at 20A 24V. MPPT solar charge controllers, on the other hand, can handle higher loads, being a better
