Solar Pump Inverters (VFD)
Water pump inverter maintains a constant and stable pressure in a water system by varying the speed of the pump motor to deliver the same pre-set pressure at the outlet regardless of how many outlets or appliances are in use, up to the maximum capability of the pump.
Maximizing power generation efficiency of solar modules with the use of advanced MPPT
control technology and automatic MPPT voltage tracking
Adjust water outflow of pumps quickly on basis of sunlight intensity change
Automatic hibernation and wake up
(1) Hibernate at high water level and wake up at low water lever
(2) Hibernate at sunrise and sunset and wake up at strong sunlight
Built-in C3 EMC filter and DSP technology and Infineon PIM design, with functions of light
weak protection, dry run and low voltage, full water warning, overvoltage and overtemperature
protection
Advanced calculation for Pump flow and LCD monitoring display
Automatic running without any commissioning in keypad control and GPRS monitoring
option(as option)
Dual supply capability with change over switch – solar and grid compatible
Available Sizes : 1 KW to 200 KW.
