With this article, you will understand what is a good solar pump inverter, its input source, supported pumps, protection function and information of solar pump inverter manufacture.
What is Solar Pump Inverter?
Solar pump inverter is a device that convert solar panel input power to AC output for pumps. The solar pumping inverter system has MPPT built-in, can maximize the energy efficiency. Solar pump inverter is also named as solar pump controller and solar pump drive.
Input Power Source
USFULL hybrid solar pump inverter supports DC input and AC input, solar panel, generator and grid power all compatible. When sunlight is not enough, AC input can be used as a supplement.
The rated power of solar pump drive ranges from 1hp to 840hp (630kW).
We manufacture drives suitable for single phase pump and three phase pump, and 220V pump, 380V pump and 480V pump all ok to use. Details will be shown on the product nameplate.
Start and Stop Control
While using solar panel alone, the solar pumping inverter can automatically restart after sunlight is getting stronger. That means, in the morning, the system will run automatically, and night time in sleep mode.
Users can use manual control to start and stop solar pump inverter as well.
Protection for Pump
Solar pump inverter is also known as solar pump VFD or solar VSD because it has the function of protect pump, adjust frequency and speed. It’s easy to set upper frequency limit and lower frequency limit. The operation method is much simplied for users.
The pump inverter support external float switch to monitor full water and empty water.
As a solar pump controller, users can add AC/DC changeover switch to select mains input or PV input.
DC breaker, DC SPD and DC fuse are recommended to be installed in solar pumping system, to better protect solar panel, inverter and pumps. If budget allowed, combiner box is useful for solar pump system. USFULL offers guidance on how to select DC breaker for PV system.
USFULL is a professional solar pump inverter manufacturer, following standard ISO procedures to conduct quality control and R&D. We have more than 10 R&D and 15 QC personnel, with over 20000 pieces of production ability every month. The solar pumping inverter is CE and TUV certified, the quality and performance both assured.
