A stand-alone inverter is supposed to work as an AC voltage source for a specified range of AC loads.
B. An ideal grid-tied inverter has its operational voltage and frequency synchronized with those of the grid.
C. A bimodal inverter can power backup loads even if the grid-connection is disrupted.
D. An ideal grid-tied inverter works as a perfect voltage source, and changes the grid voltage and frequency to match its own.

Consider the following statements related to the field of MPPT techniques:a) The PV output is never steady at the MPP.b) Inclusion of a pilot solar cell can improve the PV module's yield.c) The hardware complexity is high for implementing this design.d) The output of the PV module is maximum only if load resistance = \(\frac{V_{mpp}}{I_{mpp}}\).Consider the following conditions at the PV output:i) An MPPT device implementing Fractional Open-Circuit Voltage method.ii) An MPPT device implementing Incremental Conductance method.iii) No MPPT device connected; solar module directly connected to the load.iv) An MPPT device implementing Perturb and Observe method.
