Microinverters Maximize PV Energy Production
More Reliable than Central Inverter or String Inverter
Each PV module has individual Maximum Peak Power Tracking (MPPT) controls, which ensures that the
maximum power is exported to the utility grid regardless of the performance of the other PV modules in
the array. When PV modules in the array are affected by shade, dust, orientation, or any situation in which
one module underperforms compared with the other units, the Microinverter ensures top performance
from the array by maximizing the performance of each module within the array.
The distributed Microinverter system ensures that no single point failure exists across the PV system.
Microinverters are designed to operate at full power at ambient outdoor temperatures up to 149°F(65°C).
The inverter housing is designed for outdoor installation and complies with the IP67 environmental
enclosure rating.
NOTE: If the wireless signal in the area for the Microinverter is weak, it is necessary to add a WiFi signal booster
at a suitable place between the router and the microinverter.
This integrated system improves safety; maximizes solar energy harvest; increases system reliability
and simplifies solar system design, installation, maintenance and management.
Simple to Install
You can install individual PV modules in any combination of Module quantity and orientation, different type
and power rate. The Ground wire (PE) of the AC cable is connected to the chassis inside of the Microinverter,
potentially eliminating the installation of grounding wire(check local regulation).
Data collection adopts internal WiFi, wireless router is needed near the Microinverter. When complete the
installation of microinverter, configure wireless router with internal WiFi(refer to the WiFi user manual). The
data will be uploaded automatically. Users can monitor and manage the microinverter through corresponding
website or APP.
The Microinverters usually connect with the single-phase grid, but multiple Microinverters in the form of single-
phase grid can also achieve three-phase grid, which are matchable with most 60 and 72 cell PV modules. For
more information, please see related Technical Data(P11-12).
