VEIKONG Solar Water Pump Inverter 3 phase mppt with GPRS Remote Monitoring.
1. Key features of VFD500-PV series solar pump inverter
1. Maximizing power generation efficiency of solar modules with the use of advanced MPPT control technology and automatic MPPT voltage tracking.
2. Adjust water flow of pumps quickly on basis of sunlight intensity change.
3. Advanced calculation for pump flow and LCD monitoring display.

3.Other special design of Veikong solar pump inverter.
1. Independent air duct design, effectively preventing dust entering inverter, causing short-circuit and other faults and improving reliability.
2. Use bigger air volume and long life cooling fan effectively reduces the internal temperature rise of the inverter and ensures reliable and stable operation of inverter.
3. Perfect protection system, Designed for ten years of maintenance-free operation.
4. Cooling fan, capacitors, relays, and IGBTs have been carefully selected and designed for a life expectancy up to ten years.
4. why should we choose a higher level power solar pump
inverter than motor pump?
1. If solar pump inverter works in high temperature above 40C, it
will be derated.
2. If motor pump is far away from inverter more than 100m, there
will be power loss and drop voltage on cables and output power
will be less and more harmonic, reactor is needed to reduce
harmonics and better protection on motor.
3. Oversized power can be more adjustable for pump as it can keep
stocks for better marketing which depend on real application
for example 15hp solar pump inverter can use for 10hp also 15hp if
distance is less and temperature is not high.
4. Some deep well pump is heavy duty and more heights and pump and
motor are not matched and motor is easily overloaded so
inverter should choose oversized power.
5. Oversized power has better heat ventilation and higher IGBT
capabilities.
