Perturb and observe method
Maximum power point tracking (MPPT) is a technique that grid connected inverters, solar battery chargers and similar devices use to get the maximum possible power from one or more photovoltaic modules. Photovoltaic solar cells have a complex relationship between solar irradiance (W/square meter), temperature and total resistance that produces a non-linear output efficiency which can be analyzed based on the I-V curve. It is the purpose of the MPPT system to sample the output of the PV cells and apply the proper resistance (load) to obtain maximum power for any given environmental conditions.[citation needed] MPPT devices are typically integrated into an electric power converter system that provides voltage or current conversion, filtering, and regulation for driving various loads, including power grids, batteries, or motors.
- Solar inverters convert the DC power to AC power and may incorporate MPPT: such inverters sample the output power (I-V curve) from the solar modules and apply the proper resistance (load) so as to obtain maximum power.
- MPP(Maximum power point) is the product of the MPP voltage(Vmpp) and MPP current(Impp).

What is MPPT (Maximum Power Point Tracking) and why does it matter with solar? – SolarJOOS.com
MPPT (Maximum Power Point Tracking) charge controllers are a commonly found component in today’s battery-based renewable energy systems although they’re not commonly found in the smaller, portable solar chargers. The JOOS Orange from Solar Components is different—it has a proprietary MPPT circuit that allows the small, portable device to achieve amazing efficiency and charging capabilities not found on competing products.
