Description

SG600 Solar pump drives advantages:
KewoSG600 solar  pump drive is positioned in environmental-friendly and economical PV market, the product is applicable to PV pumping system, replaces water storage with electric storage and needs no battery modules. The direct current generated by solar modules is input to the inverter and then converted into the alternating current to drive various pumps directly. Additionally, the output frequency is adjustable in real time according to sunlight intensity change.
Fully automatic system using variable speed drive compatible with AC, 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. The system is prepared to be combined with a elevated water storage, e.g. water tower or an uphill tank installation.

SG600 solar pump inverter wiring steps.

Wiring as below attached pictures. It is accepted dual power AC/DC mode connecting input.
User can able to install a power switchover to selection which mode power input as conditions.
6.1. Wiring P+ and P- of DC solar power to R, T terminals, or 1/3 phase cables of AC power supply to R, T ( R, S, T) of inverter.( 1 phase 220VAC AC inupt connect to L, N of inverter).
6.2. Built a Run/Stop switch S1 to start pumping whensettingP0.02for 1,that inverterworks in terminals control mode.This inverter can achieve auto start at morning when sun light radiation is good, auto stop when sun set when sunlight radiation is low.
6.3. Built a switch 2 to disable solar pump control mode when connecting AC grid input.
The inverter can be used fora variable speed drive (VFD) for pumps speed adjusting as need  The output frequency can be adjusted byP0-03 frequency reference mode setting. The MPPT function is closed when turn off switch 2 and set P4.02=53. The solar pump control mode function also can be disable by parameters setting PE00=0.
6.4. Connect 2 wires of float ball sensor to DI4 and COM for water tank level fulling detecting, and set P4.03=51( float ball NO relay alarm). When water level reached to sensor detecting, the normal open (NO) relay point will be activated, invereter will stop pumping, and sent a A.FuL alarm.
6.5. Connect 2 wires of sensor of dry run sensor of well to DI5 and GND, and set F4.04=52 ( dry run NC relay alarm).
It will sent alarm A.LLd and stop pumping when lack of water in well for dry run protection.
