SG320-M mini Solar Water Pump Inverter For 3 Phase 220V AC Pumps 

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.

System connection and commissioning. 
An enhanced version of AC Drive ( variable speed drive of motor speed and torque control), compatible with DC power and AC grid input.
Note*: Only allow one power source input at a time. 
1. Connect DC power Positive ( P ) and Negative ( N ) terminals to input R, T terminals of drive.
2. Connect output U, V, W terminals of drive to 3 phase AC pumps. ( Not drive for DC pumps and Single AC pumps).
3.Connect water level sensor to drive if need water tank level detecting.
4.Connect remote controller GPRS module ( option) if need remote monitor controlling function.
5. IP54 solar pump drive cabinet customization make is available including( AC/DC switchover, AC and DC breaker..) 
Easy installation and commissioning. 
1.Total Voc (open loop circuit )voltage input from solar arrays should be large than 1.15 times of Vmpp of drives.
For example: For 4T series, recommend 540V*1.15=621V; For 2S series, recommend 311*1.15=357V. (Voc)
2.The selecting power of solar arrays need large than 1.3 times power of total pumps.
For example, 0.9kw above for 0.75kw pumps, 2.86kw above for 2.2kw pumps.
Commissioning steps.( Please wait 30s after switching on for initialization

GPRS remote control (optional)
Functions of GPRS module establishing
1. Working Status Monitoring;
2. Inverter Control and parameters review and modify
3. Positioning can see where the solar pump system working
4. History Data Record, possible record 3 months working data of system

Appendix I.
A 160kw, solar pump inverter is working good in Lebanon.
It can started working at 9:30 with above 40Hz, and stopped working at 17:00 with above 40Hz.
Because customer need pump don’t work when output frequency is less than 40Hz.
