Solar Pump Inverter VFD application

With the development of the photovoltaic industry, the efficiency of photovoltaic boards has become better. The latest developed photovoltaic pump scheme CT112 Solar Pump Inverter VFD has quietly launched and successfully applied around the world. This photovoltaic inverter has learned experience from the previous generation and combined with the feedback from end customers around the world to improve. This article will introduce the CT112 series of photovoltaic water pump inverters.

After collecting feedback information from the solar market and end users, we get the following suggestions:

1. Reduce the number of photovoltaic boards
Because ordinary solar inverters need high DC input voltage;
2. Support single -phase pump
For civil pumps, many motors are single -phase, and many photovoltaic pump inverters on the market do not support single -phase, only three phases support;
3. Support AC / PV channel input
At night, if there is no PV input energy, the pump will stop working. And some projects require the pump to always maintain working state;
4. Simple debugging
The previous generation of products need to modify some parameters to apply to different pumps, and the new inverter can automatically match the parameters for work;
5. Support remote control
Users can use mobile applications or websites to monitor the operating status of the machine, control the system start or stop working.

In order to meet the needs of end users and solve the disadvantages of photovoltaic pump inverters on the market, we have developed a new product CT112 series Solar Pump Inverter VFD to meet the above needs of customers.

CT112 series Solar Pump Inverter VFD introduction
● Suitable for single -phase or three -phase water pump, wide range of use;
● IP54 control cabinet solution, this solution can be applied to the severe outdoor environment, which can be installed directly outdoors;
● Support the boost module of less than 2.2kW to increase the PV output voltage;
● Support photovoltaic input and AC grid input, automatic switching functions can be achieved without manual intervention;
● Have water level control logic functions, avoid drying and water -free operation, and increase the full water level protection function;
● Start smoothly to reduce the pointed pulse of the motor;
● Low -start voltage and wide input voltage range provides more possibilities for receiving multi -photovoltaic string configuration and different types of photovoltaic components;

CT112-4T series:
DC input VOC voltage (V): 300 ~ 780V
Recommend DC input VOC voltage: 670 ~ 780V
Recommend MPPT voltage: 540 ~ 630V
AC input voltage: three-phase 380VAC (-15%～ 30%)

CT112 integrates many functions, such as reducing photovoltaic input voltage, switching of DC power switching and AC power switch input channels, high protection level IP54, etc. This does not need to maintain the end users after the solar inverter sets the parameters for the first time. After the sunset, the light will weaken. The CT112 Solar Pump Inverter VFD can detect that the PV voltage is less than the set value. He will automatically turn the power input channel from PV to AC grid input. If only the PV channel can input voltage, the CT112 Solar Pump Inverter VFD will sleep in the weak light and automatically wake up in the morning.
