PV Micro Inverter F-WMI300/350/400

Overview

PV Micro Inverter F-WMI300/350/400 are plug and play power conversion device used in photovoltaic systems, that convert direct current(DC) generated by PV modules to alternating current(AC) for household users and feed it into the public grid，each PV micro inverter connects to 1 PV modules.

With the smart mobile APP, operation data of the PV micro inverters can be collected easily. There are more functions in the APP, such as real-time data display for both plant-level & inverter-level as well as daily, monthly, annual, and total energy. Furthermore, users can easily see that alarm information with the equipment, which could assist the users in monitoring the operation of the PV plant, ensuring normal operation of the power plant and obtaining of the great yield.
