6 FAQs about [Photovoltaic inverter mppt current]

What is a MPPT in a solar inverter?

Does MPPT improve efficiency of a photovoltaic (PV) generation system?

An efficient maximum power point tracking (MPPT) method plays an important role to improve the efficiency of a photovoltaic (PV) generation system. This study provides an extensive review of the current status of MPPT methods for PV systems which are classified into eight categories.

What happens if a PV inverter does not have an MPPT circuit?

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.

Do all inverters perform global MPPT?

Importantly, not all inverters perform global MPPT. Some inverters are limited to only search for the maximum power point in a local region where it “usually” lies, a high voltage solution where no modules are bypassed.

Can a single-channel MPPT inverter connect two solar arrays?

Connecting two arrays with different solar azimuths or tilts, different string lengths (Voc) or different PV modules to a single-channel MPPT inverter would result in a highly inefficient system and, in some instances, an unsafe one.

Does MPPT affect power generation efficiency?

Yes, it will affect the normal power generation of another string because the MPPT algorithm adjusts the voltage to find the maximum power point. In this case, there will be two power peaks, and the MPPT tracking point will be lower than normal, reducing the power generation efficiency.
