How many models are in the IQ7 inverter line?

• A. 1
• B. 4
• C. 2
• D. 3

Answer: (B)

The idea being tested is how a product line is structured to fit different installation needs. The IQ7 inverter family is designed with four distinct models to cover different module power ranges and regional grid requirements. Each model targets a specific input current and voltage setup, ensuring safe operation, proper communication with the Enphase system, and optimized performance for the modules and local electrical standards. Because of this, there are four models in the IQ7 line, making four the correct count. If you’re thinking there should be fewer or more, remember that Enphase created these four variants to match common residential configurations and grid rules, rather than a single universal option.
