Veichi 37kW 3 Phase Hybrid Solar Water Pumping Inverter
The Veichi 37kW 3 Phase Hybrid Solar Water Pumping Inverter is a device that converts solar energy into AC (alternating current) electricity to power water pumps. It is specifically designed for use in solar water pumping systems, which are used to pump water from wells, rivers, or lakes using the power of the sun.
The Veichi 37kW 3 Phase Hybrid Solar Water Pumping Inverter is a three-phase inverter, which means that it can output AC power at three different voltages and phases. This is important for use with three-phase water pumps, which are more powerful than single-phase pumps.
The inverter is also a hybrid inverter, which means that it can also be used with a grid connection. This means that if the solar panels are not producing enough power to run the pump, the inverter can draw power from the grid to supplement the solar power.
The inverter is also equipped with MPPT (Maximum Power Point Tracking) technology, which ensures that the solar panels are always operating at their maximum power output. This helps to improve the efficiency of the solar water pumping system.
Here are some of the key features of the Veichi 37kW 3 Phase Hybrid Solar Water Pumping Inverter:
- 37 kW power output
- Three-phase output
- MPPT technology
- Grid connection capability
- Online remote monitoring
