Solar Pump Inverter: Environment Friendly and Cost Effective
A solar pump inverter is a device used to convert the direct current from the solar panels into alternating current that can be used to power a solar pump. Generally the power range of solar pump inverters ranges between 0.15 to 55 kw. Modern solar pump inverters automatically adapt to various changes and cloudy weather, thus effectively avoiding the phenomenon of a sudden stopping of the solar pump due to sudden overcast conditions. Furthermore, the solar pump inverters come with advanced control systems and can track the maximum power of solar panels with the added ability to increase the output power of solar panels if required.
Solar pumps are used for drawing out water from a source and moving it to the required location for use in irrigation purposes, as drinking water for livestock, for filling up swimming pools, for waste water treatment and also for supplying to homes. These are gradually replacing traditional fuel based pumps owing to their minimal operating costs and zero emission of greenhouse gases. These two features provide monetary savings and reduce environmental damage respectively.
Solar pumps are generally ideal for use in small scale or community based operations. Their usage for large scale operations is usually restricted owing to logistical and handling reasons. The solar pump inverters enable the solar pumps to overcome the aforesaid limitations and make them suitable to be used for irrigation of larger fields or farms.
Suitability of Solar Pump Inverters for Different Solar Pump Systems
The solar pump inverters are perfect for all kinds of solar pump systems, whether it be;
Centrifugal solar pump
Axial flow solar pump
Mixed flow solar pump
Deep flow solar pump
Salient Features of Solar Pump Inverters
High operational fluency.
Very high conversion efficiency of around 98 percent.
Solar pump inverters come with optimal running protection mechanism, such as output short circuit protection, voltage fluctuation protection, overload protection, grounding protection and many more.
These inverters operate within the defined speed limits, as in a minimum and maximum pump speed threshold has to be maintained.
Solar pump inverters also provide the pump cleaning function to prevent solids from building up on pump impellers or piping.
Safety Instructions to Be Followed During Installation or Maintenance of Solar Pump Inverters
Never work on the photovoltaic generator or inverter and it's input/output cables when the inverter is connected to the power system.
Switch off the axillary voltage supply to the inverter before working inside the inverter cabinet.
Never touch the input of the isolation switch because it has high direct current passing through it.
After disconnecting the inverter from the DC input supply, wait for some time to discharge the intermediate circuit capacitors.
