What is a microinverter?

Microinverters perform the same basic function as string inverters: they transfer Direct Current (DC) power to Alternating Current (AC) power. However, microinverters are about the size of an internet router. As a result, they can be installed directly under solar panels.
Easier and more efficient installation
With a string inverter, solar panels need to be installed in series, then connected to a string inverter at the end. This limits the electricity production of each panel to the lowest producing panel on your roof.
Microinverters are installed in a parallel circuit. This means each panel is directly connected to a microinverter. Depending on your microinverter model, you can connect up to six panels to a single microinverter.
As a result, a microinverter can take full advantage of the production of each individual panel. Each solar panel and microinverter combination can perform at its best, contributing more power.
Why some solar panels limit your installation
Solar panels can generate different amounts of power depending on a wide variety of factors.
These include:
● Shade caused by trees, buildings, or other rooftop structures.
● Soiling including dust, snow, or bird droppings
● Panel faults like micro cracking, hot spots, water ingress, or manufacturing issues
● Temperature fluctuations at different times of the day
● Aged panels with performance degradation
● Poor panel mounting or complex roof layouts
● Smaller roofs with only a limited number of panels
In a standard string installation, your panels are linked together in series. If one of your panels doesn’t perform, the entire installation is affected.
Microinverters let you monitor and optimize each individual panel, generating the maximum power.
