SK3000GPRS Pump Control Monitor for use with SQFlex and SPFlex pumps

We have been searching for a pump controller like this for years and are so excited to bring you the SK3000. This controller provides similar functions to both the Grundfos CU200 and the IO101 controllers in one unit. It also has added functionality providing auto generator start function and auto switching between dc and an ac power source. So when the sun goes down it will automatically pull power the pump from an ac source and then when the sun comes up the next day it will power the pump from the dc solar source.

We have two models of the SK3000 monitor available. One with remote montoring and control SK3000GPRS and the non GPRS SK3000.

Monitor Description
The SK3000 Monitor is not a necessary part of a solar pumping system, but it does provide more functions and
protections for your pump system while making the system more convenient and intelligent.

For example: intelligent switching of AC/DC power supply; Float terminal; Power display; GPRS
remote monitoring and control ( SK3000GPRS only) etc.
The monitor is suitable for outdoor installation and is weather-proof, however, its
location/positioning against direct sunlight should be avoided.

The Monitor is capable of the following functions:
1. Display input power AC / DC;
2. Display of tank full / tank empty;
3. Intelligent mode(Three modes can be chosen);
