Furthermore, the IO 102 enables the combination of
wind energy from the wind turbine and solar energy
from the solar panels.
The IO 102 functions as a connection box joining all
necessary cables.

Charge controller
The charge controller is used when a battery backup
system is installed with an SQFlex pumping system.
These systems are typically used in applications where
the pump is not running during most of the peak sun
hours of the day, or where it is impossible or
impractical to store large volumes of water. Examples
include remote homes or cabins, automatic livestock
waterers and very low-yielding wells.
The charge controller is a fully automatic battery
charger and the only setting required is the selection of
battery type.
There are three battery types to choose from:
• gel battery
• sealed battery
• flooded battery.
The charge controller enables manual disconnection of
the pump, the solar modules or both at the same time.
Submersible drop cables
The submersible drop cables for SQF pumps are
approved for use with potable water (KTW-approved).
The cables are made of EPR (ethylene-propylene
rubber).
Sizing of cable
Use the following formula:
where
L = Length of cable [ft]
P = Power loss [%]
q = Cross section of submersible drop cable [in
2
]
V
mp
= Maximum power voltage [V]
Wp = Watt peak [Wp]
The sizing tool in Grundfos WinCAPS makes it
possible to calculate the exact losses.
