[User-Friendly Display]High visibility red digital display ensures easy readings and controls for efficient operation. [Robust Design]Featuring a simplified and durable PCB layout that minimizes malfunction risks. [Versatile Functions]Includes a built-in MPPT controller for maximum power tracking and various programmable interfaces. [Enhanced Safety Features]Incorporates over current, overload, and short circuit safety to protect equipment during operation. Item Type: Variable Frequency Inverter Material: PC Mystical/Fantasy Retardant, Aluminum Input Voltage: DC400-700V Output Voltage: 3PH 0-380VAC 0-600Hz Rated Power: 4KW Rated Current: 8.5A How to use: 1. Built in MPPT controller, maximum power point tracking. Detect the power generation voltage of solar panels in real time, track the maximum voltage and current value (VI), so that the system output the maximum power driving load, applied to solar photovoltaic systems, coordinate the work between solar panels and loads. It's the brain of the photovoltaic system. 2. Support wide voltage input; A, 220V photovoltaic converter corresponding to the input voltage below 200V will low voltage alarm shutdown, more than 400V automatically inhibit voltage rise, avoid ignoring overvoltage shutdown; B, 380V photovoltaic converter corresponding to the input voltage below 400V will low voltage alarm shutdown, higher than 700V automatic suppression voltage rise to avoid over voltage shutdown. 3. Support unattended automatic start and stop. In the morning, when the light intensity rises to a certain extent and the input voltage reaches about 400 V (220 V photovoltaic converter reaches about 200 V), the photovoltaic converter automatically starts the drive load operation without manual operation. In the evening, when the light intensity drops to a certain
