Grundfos SQFlex Solar Pump (maximum efficiency)

In this blog post, we show you the main advantages of the Grundfos SQFlex solar pump.

This solar pump is designed for continuous or intermittent operation and especially suitable for water supply on farms, irrigation, ponds, lakes etc… . The SQFlex Solar pump can be connected to solar panels, wind turbine, batteries, power pack, and even the mains. The motor has been specially developed for the SQFlex system and is designed according to the permanent magnet principle with a built-in electronic unit. A wide voltage range allows the motor to operate at any voltage from 30-300 DC or 90-240AC, making installation and sizing particularly easy.

This system is one of the greats advantages that have Grundfos SQFlex pumps and can be very useful in places where we need the pump to run during the night because we can install solar panels to run during the day and automatically connect to the mains when there is no sun.

Another advantage of this solar pump is the dry well probe, which is included in the pump itself and allows us to be calm in the event that our well runs out of water, when the water level drops below the water level electrode the pump is disconnected. It automatically switches on again when the water level has been above the water level electrode for 5 minutes.

But not only that, the Grundfos SQFlex solar pump incorporates protections

Overvoltage or undervoltage protection

When the supply voltage is unstable, overvoltage or undervoltage may occur. The pump will stop if the voltage falls outside the allowable voltage range. The motor restarts automatically when the voltage is within the allowable range. Therefore no additional protection relay is needed.
Overload protection
. The motor will be stopped for 10 seconds. After this time, the pump will automatically attempt to restart. The overload protection prevents the motor from burning out, so no additional motor protection
is required.

Overtemperature protection When the temperature rises above 85°C, the motor stops automatically; when the temperature has dropped to 75°C, the
motor restarts automatically.

These characteristics of the SQFlex pump guarantee an easy installation, and also allow a saving in protection systems, which sometimes are not adequate.

Benefits of its operation.

Maximum point tracking
power (MPPT)
The built-in electronic unit provides a number of advantages to the SQFlex system compared to conventional products. One of these advantages is the built-in microprocessor with MPPT (maximum power point tracking).
Thanks to the MMPT function, the pump duty point is continuously optimized according to the available input power. MPPT is only available for pumps connected to DC power.

Reliability
The MSF 3 motor has been developed with
high reliability in mind, which is achieved through the following features:

– carbon/ceramic bearings
– excellent starting characteristics
– various protection facilities.

PRICE

This is one of the important parts, Grudfos SQflex pumps have an average price compared to its competitors, but perhaps it is one of the pumps with more profitability by the hardness and resistance that characterizes them. At the end of the day, the price of the solar pump is as important as its useful life and that it continues to work over the years, and that is why the Grundfos SQFlex pump is one of the best options in solar pumping.
