Photovoltaic modules connected in series to meet the inverter
Connecting in series means joining the positive terminal of a solar panel to the negative terminal of the next solar panel until eventually you are left with one free positive and one free negative terminal of the array, which are to be connected to the input either of the inverter (in case of a grid-tied system without a battery backup) or the charge controller (in case of a grid-tied system with a battery backup or off-grid solar panel system).

FAQS about Voltage change after inverter half-wave rectification
How does a half wave rectifier work?
It is done by using a diode or a group of diodes. Half wave rectifiers use one diode, while a full wave rectifier uses multiple diodes. The working of a half wave rectifier takes advantage of the fact that diodes only allow current to flow in one direction. A half wave rectifier is the simplest form of rectifier available.
Why are half-wave rectifiers more efficient than full wave rectifiers?
High power loss: Efficiency is reduced due to the utilization of only half of the input waveform, resulting in higher power dissipation. Low efficiency: Compared to full-wave rectifiers, half-wave rectifiers have lower efficiency because they utilize only one half of the input cycle.

What is pulsating DC in a half-wave rectifier?
In a Half-wave rectifier, only one half-cycle of AC is converted to DC and the other half-cycle is blocked. Therefore, the output waveform produced by a half-wave rectifier consists of ripples of positive half-cycle of the input waveform and it is called pulsating DC. In a half-wave rectifier, a p-n junction diode is used as a rectifier.
What is ripple factor of half wave rectifier?
