NOTE: If the wireless signal in the area where the Micro Inverter is installed is weak, it is necessary to add a wifi signal booster at a suitable place between the router and the Micro Inverter This integrated system improves safety; maximizes solar energy harvest; increases system reliability, and simplifies solar system design, installation, maintenance, and management.

Microinverters Maximize PV Energy Production
Each PV module has individual Maximum Peak Power Tracking (MPPT) controls, which ensure 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 Micro Inverter ensures top performance from the array by maximizing the performance of each module within the array.

More Reliable than Centralized or String Inverters

• The distributed micro-inverter system ensures that no single point of system failure exists across the PV system.
• Microinverters are designed to operate at full power at ambient outdoor temperatures of up to 113℉ (45℃).
• The inverter housing is designed for outdoor installation and complies with the IP67 environmental enclosure rating.

Simple to Install

• You can install individual PV modules in any combination of Module quantity, orientation, different types and power rates. The Ground wire (PE) of the AC cable is connected to the chassis inside of the Micro Inverter, potentially eliminating the installation of grounding wire (check local regulation).
• Data collection adopts internal wifi, wireless router is needed near the Micro Inverter. When completing the installation of the Micro Inverter, configure the wireless router with internal wifi(refer to the wifi user manual). The data will be uploaded automatically. Users can monitor and manage the Micro Inverter through the corresponding website or APP.

Micro Inverter Introduction
