Question

Which of the following Two options are potential

benefits of using DC-DC converter.
Select two:
- Module-level MPPT helps minimize the impacts of
shading
- No string in inverter is required when using

Answer 1

Two potential benefits of using a DC-DC converter are module-level MPPT and no string inverter requirement.

Step-by-step explanation:

Two potential benefits of using a DC-DC converter are:

1. Module-level MPPT helps minimize the impacts of shading: MPPT stands for Maximum Power Point Tracking and it is a technique used to optimize the power output of a photovoltaic system. By using a DC-DC converter at the module level, each module can track its individual maximum power point, reducing the impact of shading on the overall system performance.
2. No string inverter is required when using a DC-DC converter: A string inverter is a device used to convert the DC power generated by multiple solar panels connected in series into AC power. When using a DC-DC converter, each module operates independently and does not require a string inverter to convert the DC power into AC power.

Answer 2

The two options you should select are:

Module-level MPPT helps minimize the impacts of shading

No string inverter is required when using DC-DC converter

Based on the information provided, the two potential benefits of using a DC-DC converter are:

1. Module-level MPPT helps minimize the impacts of shading: Each solar panel in a string can be affected by shading differently. A DC-DC converter allows for individual Maximum Power Point Tracking (MPPT) for each panel, maximizing energy production even if some panels are shaded.

2. No string inverter is required when using DC-DC converters: With DC-DC converters, each panel can be connected directly to the microinverter, eliminating the need for a string inverter.

Therefore, the two options you should select are:
