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 jump 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 jump 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 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.

Note:
1. The default upper frequency of this solar photovoltaic inverter is 50HZ, the default is to turn off the reverse function, if you need to change, please follow the instructions to use correctly.
2. DC input voltage please try to meet the recommended voltage, otherwise it will reduce the solar conversion rate.
3. AC input and DC input switch can not be closed at the same time, otherwise it will damage the inverter or solar panel.
4. Do not overload the use of frequency converter, such as the frequency converter power is smaller than the motor power, or the ordinary motor is greater than 50HZ operation, whether the side of the frequency converter will frequently jump overload protection failure, or even explode the machine, the motor may also overheat and burn out.
5. Solar special inverter, suitable for solar photovoltaic panel power generation fan pump and other motor load. The selection can be selected according to the corresponding motor voltage and power. If the water depth of the submersible pump exceeds 30 meters, it is recommended to enlarge one or two stages to select a frequency converter, and add a reactor between the frequency converter and the pump. Otherwise, the service life of the inverter will be reduced.
6. About how to connect solar panels, such as 220V motor, the total voltage of solar panels connected in series needs to meet 200V-400V. 380V motor, the total series voltage should meet 400V-700V. The power is that the total power of several groups of series solar panels in parallel is more than 1.2 times greater than the power of the inverter.
