Specifications
Shenzhen ZK SG320 Solar Pump InverterFully automatic system using variable speed drive compatible with AC, 1 /3-phase, submersible and surface mount pumps, and high efficiency PMSM Pumps. the system is composed of a PV generator, a pump and a solar pump drive. Based on the design philosophy that it is more efficient to store water rather than electricity, there is no energy storing device such as storage battery in the system.
Solar Water Pumping Solution is a fully automatic system designed to provide water at affordable cost for people with limited or no access to electricity. It uses the most advanced S300/3200 variable speed drive to regulate the speed of a 3-phase AC motor depending upon the solar energy available from the solar panel.
how does it work?
An arrays of solar panels generates the power and voltage required for the SG200/320 solar inverter to drive the motor. the solar pump inverter converts the DC voltage input to a 3 phase AC output with variable voltage and frequency. the MPPT algorithm of solar pump inverter extracts maximum power available from the solar panels during the day and operates the motor at variable speed based on the power input to the inverter. the frequency range in which the inverter operates depends upon the motors peed, hydraulic system and the power available from the solar panel. As the sunshine varies during the day, power input to the inverter varies and generates variable V/F ratio thus controlling the speed of the motor, which in turn regulates the pump impeller speed.
It is no need install battery for investment saving.
It is very suitable for 110VAC/220VAC/380VAC induction motor pumps and PMSM high efficiency pumps.
We also provide 1.5kw solar voltage booster to increase your solar panel voltage for saving solar panel sinvest.FeaturesControl mode: VF for induction motor pumps, open loop vector control for PMSM high speed pumps
MPPT function: always performance MPPT for gain highest efficiency
CVT: When sunlight is good, can select CVT control for excellent stable frequency output.
Dry run function: When little water or no water for pumping to protect pumps.
Maximum current protection: set maximum current protection is available
Minimum solar input power: When low power input, inverter no work
Stop frequency: Lower than stop frequency, inverter no work
Sleep mode: if lower than sleep voltage, inverter go to sleep, it will wake up when DC voltage rise.
Flow and generated energy calculating and monitoring
A lot of fault protection. Short circuit, ground short circuit, phase loss, over current, overheat
Built in RS485 interface, it is easy to connect GPRS remote controller.
