List three typical ratings used to specify PV modules and inverters.

PV components are described by a set of ratings that tell you what they can deliver and under what conditions. For PV modules, the typical numbers describe how much power they can produce under standard conditions (rated power, Wp), the maximum voltage when no current is drawn (open-circuit voltage, Voc), and the maximum current when the circuit is shorted (short-circuit current, Isc). These three figures help you size the array and verify voltage and current limits in the system. For inverters, the usual specifications include the AC output power rating (the maximum AC power the inverter can supply), the efficiency (how much of the DC energy is converted to usable AC power, accounting for losses), and the input voltage range (the DC voltage it can accept while operating, which determines which array configurations and MPPT settings stay within its operating window). Together these tell you whether the inverter can handle the expected array output and at what voltage levels. The other options mix in incorrect concepts: Watt-hours is energy, not a constant rating of a module; voltage or current alone lack the necessary context; and non-electrical attributes like hail resistance, color, or even battery compatibility features are not standard module or inverter ratings. So the set of ratings that matches common practice is the one that uses rated power with Voc and Isc for modules and AC output power, efficiency, and input voltage range for inverters.
