Grundfos: SQFlex Control Box
CU200 SQFlex Control Box, Solar/Wind Monitor with Float Switch Terminals

The CU 200 is a combined status, control and communication unit especially developed for the SQFlex system. The CU
200 also enables connection of a level switch.
The CU 200 incorporates cable entries for power supply connection pump connection ground connection level switch
connection
Communication between the CU 200 and the pump takes place via the pump power supply cable. This is called mains
borne signalling (or Power Line Communication), and this principle means that no extra cables between the CU 200  
and the pump are required. It is possible to start, stop and reset the pump with the on/off button

Grundfos: SQFlex Water Level Switch
SQFlex Water Level Switch

The float switch regulates the liquid level in tanks, wells, etc. and is used for automatic level control in combination with
groundwater, wastewater and sewage pumps, for raw water and liquid transfer pumps at waterworks, and for high
water alarm etc. The float switches are of the non-mercury type and are available for standard pumps and
explosion-proof pumps. The latter has a blue cable which is connected for explosive environments via intrinsically safe
relays. Due to the chemical and thermal properties of the water-proof polypropylene housing
as well as the thermoplastic rubber cable, the float switch is resistant to alcohol, uric acid, faecal sewage water, oils,
petrol, fruit acid, etc.and even to many chemicals.

Delta DC Lightning Arrestor 3 Wire, 500VDC LA 302DC
Rapid response, high current Delta DC Lightning Arrestors protect your sensitive solar or wind energy systems from
nearby lightning strikes. The Delta LA Series handles the big surges, like lightning up to 50,000 amps, passing them
harmlessly to the ground. The once optional vent valve is now installed on every Delta DC lightning arrestor, which will
keep the case from rupturing in the event of the arrestor taking a strike. A small vent on the bottom of the case will open.

While it is not possible to achieve 100% protection, Delta units will greatly reduce problems due to lightning, power
surges and voltage spikes. The LA302DC model is ideal for photovoltaic and other limited current DC applications.
Grundfos: SQFlex 11SQF-2
The SQFlex family is an environmentally-friendly water supply
solution. SQFlex pumps are fitted with a permanent magnet
motor which enables the efficient use of energy
from nature. The pump system offers the perfect water supply
solution in remote areas where water is scarce and the power
supply is non-existent or unreliable.

The SQFlex solar panels and wind turbines adapt to the
characteristic weather profile of any given area. A battery
backup system can store the extra energy generated
and take over when the energy from nature is not available.

SQFlex is more than just a pump – it's a complete intelligent
system. Thanks to its built-in electronics, the pump is
compatible with both DC and AC power supply without
requiring an external inverter.

The complete range consists of ten different pump sizes: Four
helical rotor pumps for applications where a high head is
required, and six centrifugal pumps for
applications where a greater flow rate is necessary.
Solar panels
Polycrystalline solar panels are made from similar silicon material hence instead of going through the
slow and more expensive process of creating a single
crystal, molten silicon is just put into a cast and cooled
with a seed crystal. By using the casting method, the crystal surrounding the seed is
not uniform and branches into
many, smaller
crystals, thus the term “polycrystalline”. The surface has a jumbled look with many variations of blue
color.
