As we know, the PV array produces dc power, and therefore, when a stand-alone PV system contains an AC load, it is required to convert dc to ac. The inverter is characterized by a power-dependent efficiency. The role of the inverter is to keep the AC side voltage constant at the rated voltage of 220 volts.
Optimal design of stand-alone hybrid PV/wind/biomass/battery
Maleki and Pourfayaz [11], proposed an optimal sizing algorithm for stand-alone hybrid systems based on PV, WT, and diesel generators.

Determining Electrical Load for Stand-Alone PV System Sizing
This means the PV system must be sized large enough to handle whatever the electrical load is. Image used courtesy of Pexels . In certain applications, a PV system designer could use only direct current loads, so an inverter would not be needed. Because inverters are not 100% efficient, this helps minimize a stand-alone PV system''s overall size
