MORE INFO ON MAXIMUM POWER POINT TRACKING

What Is A MPPT?

MPPT stands for Maximum Power Point Tracker. It is a circuit (typically a DC to DC converter) employed in the majority of modern photovoltaic inverters. Its function is to maximize the energy available from the connected solar module arrays at any time during its operation.

Why Is A MPPT Necessary?

A solar module is a limited energy DC supply and has internal impedances that vary throughout the course of the day, depending primarily on the level of solar irradiance impinging on the module face and the cell temperature.

An inverter without an MPPT circuit would result in sub-par or non-optimal operating conditions between any PV module (or string of modules) and the inverter. Unless the inverter can match the strings to extract maximum power the result is a lower efficiency operation for the connected strings. The MPPT circuit constantly monitors the array voltage and current. It attempts to drive the operating point of the inverter to the maximum power point of the array, resulting in the highest energy harvest.

MPPT And Monitoring

Single MPPT channel inverters can only provide monitoring data at the entire array level. Whether one, two or four strings, data collection will be based on the overall array input. With independent dual MPPT channels, the inverter can provide monitoring information at the MPPT channel level. As a result, there is a finer granularity in the monitoring data, such as site status, energy production and troubleshooting data.
