Subject
to borehole capacity, up to five Solar Spring units can be placed in 6" internal
diameter boreholes. The more the pumps installed the more experienced the
installer needs to be. Competence is required to install five units in one
bore-hole. Feed pipes, electric cables, and safety ropes must not get tangled
with those of other pumping units.
Multiple
pump installations are important because they enable considerable savings to be
made on drilling costs, to the point where the cost of the solar pumping systems
can be lower than the amount saved on drilling costs. Solar Spring pumps are
capable of pumping at great heads and of forcing water over several kilometres
if necessary to dedicated water tanks near users' houses.
For
a drawing of a multiple pump installation, please refer to the drawing showing
multiple pump
systems.
The
Sunprimer electronics units incorporate five functions:
1)
To interrupt current connection between the PV panels and the pump when
irradiance or the battery charge is such that voltage is so low, about 22V, that
the pump slows down to the point where it stops. This stops the motor from being
put under continuous load when stopped.
2)
To start your Solar Spring pump as early as possible in the morning and keep it
going as long as possible into the evening (thus extending running time),
provided irradiance or battery charge is sufficient to keep the pump running. If
the pump cannot start, or is turning too slowly, function 1 enters into
operation. If irradiance is reasonable, function 2) will make another attempt to
start the pump. A secondary timer unit attempts to start the pump at intervals
of approximately two-three minutes. This timer also operates on initial starting
up, so that the pump will start operating APPROXIMATELY TWO-THREE MINUTES AFTER
ELECTRICAL CONTACT HAS BEEN MADE.
3)
To switch nominal voltage between 48V and 24V in relation to the available power
from the PV panels and pump load, so as to optimise amperage absorbed by the
pump motor and adjust motor speed as required to optimise pump capacity. It does
this by automatically connecting all the panels in series or in two sets each of
two panels in parallel, according to irradiance and the load on the pump. This
enables the pump to operate better in slightly cloudy conditions and/or earlier
in the morning and later in the evening. This device performs some of the
functions of traditional "boosters". The controller charges the capacitor to 60V
in 48V, 24V direct, and battery applications. The controller starts in 48V mode,
then switches to 24V if insufficient current is available.
4)
To connect the Solar Spring pump to GOOD QUALITY external float switches and/or
other devices such as pre-sostates. This is the smallest cable which comes out
of the Sunprimer. It has two wires which, when placed in contact with one
another or in an electrical circuit, interrupt the electricity supply. When the
two wires are not in contact with one another or in an electrical circuit, the
controller feeds current to the pump motor and, assuming irradiance is
sufficient, the pump will start again after about three minutes. External
controls or switches used should be of high quality and such that on and off
contacts be made cleanly, precisely and quickly. Uncertain or irregular contacts
may damage the controller and may shorten the life of the motor brushes.
5)
To save pump motor and system components where specifications are not complied
with during installation and/or in the presence of particular extreme or
unforeseen environmental events (including freezing or blocking of the feed pipe
system for any other reason or excessive draw-down of water in the borehole)
where a fail-safe system is needed. For instance this function intervenes to cut
current where current is greater than 4.5 amps for more than half a second.
Normal starting procedures will then be activated, so the pump will attempt to
start again after approximately two minutes (Sunprimer Mk II). Another device
will act to cut current to the controller by putting the PV panels into short
circuit when for any reason the main transistor in the controller is damaged so
that the controller can no longer work properly. The pump will automatically
start again once the damaged transistor has been repaired.
6)
The Sunprimer Mk II controller does not have a minimum current control to switch
the pump off when it is running dry. The pump can run dry for days or even weeks
without suffering undue harm. It has been assumed that where dry running is not
immediately obvious to users, those interested will carry out periodic checks to
make sure the pump is in fact pumping water.
