Ref	Function	Standalone/grid connected	MPPT	Transformer	Powered from	THD	Control type	System robustness
[29]	DC to AC	Standalone	No	Yes	Battery source	THD voltage 2%	Multilevel PWM control	Fair
[30]	MPPT+DC to AC	Standalone	Yes	Yes	PV source	—	Proposed MPPT	Fair
[31]	MPPT+DC to AC	Standalone	Yes	No	PV source	THD voltage 2.7%	SPWM	Poor
[17]	DC to AC	Standalone+grid connected	No	No	Battery source	THD voltage 1.29%	Back-stepping	Favorable
[32]	DC to AC	Standalone	No	No	Battery source	—	Direct quadrature and droop Lyapunov	Fair
