Description:
• Built-in MPPT controller.
MPPT: full name "Maximum Power Points Tracking". It can detect the generation voltage of solar panels in real time, and track the maximum voltage and current value (VI), so that the system can output the driving load with the maximum power and apply it to solar photovoltaic system to coordinate the work between solar panels and loads. It's the brain of photovoltaic systems.
• Supporting Wide Voltage Input.
380V photovoltaic converter corresponding input voltage below 400V will jump low-voltage alarm shutdown, 700V above automatically suppress voltage rise, avoid overlooking overvoltage shutdown.
• Support unattended automatic start and stop.
In the morning, when the illumination intensity rises to a certain extent, the input voltage reaches about 400 V (220 V photovoltaic converter reaches about 200 V), and the photovoltaic converter automatically starts driving load operation without manual operation.
In the evening, when the illumination intensity decreases to a certain extent, the input voltage drops to about 400 V (220 V photovoltaic converter reaches about 200 V), and the photovoltaic converter automatically stops driving the load without manual operation.
• Our products can provide motor protection function.
Such as Short-circuit, phase-absence, over-current, over-voltage, under-voltage, over-heat, over-load protection, etc.
