Rapid shutdown capability 

New electrical codes require rapid solar system shutdown so first responders or firefighters are safe from high voltage when they need to be on rooftops or servicing power lines. Microinverters comply with these rapid shutdown requirements and have this capability embedded into each module. 

More electricity  

The core advantage of using microinverters is that theoretically, you can yield more solar electricity. The reason for this is that there are slight differences in currents between solar panels. When solar panels are in a string, the current is reduced to that of the least-producing panel in the string.

Suitability for challenging installation conditions

If a solar system is facing multiple angles, meaning some panels are facing south, some east, and some west, then microinverters are the way to go. Or, if you have shading issues from trees or a large chimney, again microinverters would be best. In these situations, the solar panels will be producing different amounts of electricity at different times of the day, but microinverters will ensure you harvest all of the energy, while with a standard inverter you will lose some of this production. 

Lifespan 

Microinverters typically have 25-year warranties while standard inverters typically have 8 to 12 year warranties. The reliability of microinverters was in question several years ago, but the technology now has caught up with the industry and the long warranties on microinverters show the confidence the manufacturers have in their products

Panel-level monitoring

Microinverters have the ability to track the production of each individual panel, while with a standard inverter you only can track the production of the whole system.

System expansion ease 

If you were to expand your system in the future, microinverters are simple to add one at a time. Each panel and microinverter pair can be easily added to your existing solar array without needing to worry about purchasing, siting, and installing additional string inverters.
