INSTALLATION DETAILS
Ensure there are no shadows or other obstructions on the solar panels. While shadowing a small
corner of a single panel may not seem like a big deal, since the panels are connected in series, a small
shadow can limit the power output from all other panels connected in series! This means a small
shadow on a single panel could reduce system power by hundreds of watts. Time to get out that
chainsaw and trim some trees!
Solar Power Train Controller — Your Controller is not waterproof and should be located in a dry
dust-free location, protected from the sun and the elements and pests such as mice and bugs. Mice love
to chew wires and spiders and moths will build nests wherever they can find room. While we
understand you cannot eliminate all pests, it might be time to spray some insecticides around your
shed and set some mousetraps! There is nothing worse than finding insulation chewed off your
electrical wires. *The fan remains running in low power mode at all times to protect the equipment. This
fan uses very little power and it running, increases the lifetime of the system.
Tankless Pressure Pump or Eco-Steady Booster Pump - Your pump is designed for use out of the
direct elements, sun, rain and snow. Covering or building into a small enclosure is ideal. Since water
does expand when it freezes, care should be taken to winterize the system if being used in a climate
that experiences hard freezing. If foot valve is being used, care should be taken in plumbing the intake
to ensure tight connections which will avoid the loss of prime.
Batteries - Unless you already bought a system that included the appropriate number of RPS Deep
Cycle batteries, customers will need to supply their own battery bank. RPS recommends 12V AGM /
GEL / sealed lead acid batteries that are designed for maintenance free operation. More common
flooded deep cycle marine or RV batteries can also be used. Batteries should be stored in a dry location
protected from the elements. See page on wiring batteries.
SOLAR PANELS — Solar panels should be
mounted on a secure structure, ground mount
or top of pole mount. Several ideas can be found
at RPSSolarPumps.com. Panels should face true
South and at an angle appropriate for your
latitude. If you are mounting your panels on an
already built structure, try to get as close to the
correct angle as possible.

PLUMBING OPTIONS
* Important: Care
should be taken when
plumbing to ensure
tight connections and
maintain prime. Use
teflon tape or thread
sealant (recommended)
on all connections.
Minor leaks or seepage
will cause the pump to
cycle and deplete the
batteries.
Pressure Pumps can plumb directly
from your storage tank to your main line.
It will auto-adjust speed and power
usage to maintain the set pressure.
You can also draw water up from a pond,
shallow well or cistern (up to 15ft) but
you must maintain prime with a
foot-valve and tight connections.

With both the RPS Tankless
Pressure Pump™ and
Eco-Steady Booster
Pumps™ you'll get smooth
continuous, steady, reliable
water pressure without the
need for AC power or the
utility grid.
The solar charged battery
bank powers your pump
through your Solar Power
Train™. The pump varies its
speed and power based on
your demand for water at the
exact pressure you select,
20psi and up! Quick Connect MC4 clips and
20’ of solar wire allow for the
connection of your solar
array to your controller
Pre-attached + and -
wires connect the
controller to your
24V battery bank
(48V for BP2, BP3)
Once the pump is ready for
power/primed with water,
the pump’s 3-prong male
plug can be inserted
directly into the outlet of
the controller.
(Optional) AC power
from a generator or
the grid can
supplement solar in
charging the battery
bank.

PRIMING THE PUMP

ASSEMBLY
** With stainless steel connections, RPS engineers and past
customers recommend Thread Sealant and large wrenches.
1) First thread your Tee with Pressure Sensor to the upper
outlet of the pump chamber using ample pipe dope/thread
sealant.
2) On the left and right sides of the Tee are two openings for
small fittings. On one side goes the closed fitting. On the other
side you remove the sensor from the small metal fitting, screw
the fitting tight, and then reattach the sensor plug to the pump
control interface.
3) The top of the tee is where the tank will go. Spin on the tank
until tight using ample pipe dope/thread sealant.
4) The tank is assembled and ready for you to add your inlet
and outlet connections. Remember to use adequate pipe dope
to ensure a tight, leak proof connection between fittings.

VC3 & VC5 Series
You will link your solar panels together and
connect to the controller by clipping MC4
connectors together. Each MC4 connector is
either a male end or female end (see image). They
simply snap together to make safe
and easy connections.
Note: If using your own solar
panels do not exceed 90Voc
input for the VC3 and do not
exceed 145 Voc for the VC5! Ask
an RPS Engineer how to wire if
you’re unsure!

VC3.22 & VC3.11 Solar Power Train™
BATTERY WIRING 24V (TP750 & BP1)
RPS recommends AGM / sealed lead acid batteries that are designed for several maintenance free
years of operation. They should also be stored in a dry location protected from the elements. To
prevent significant voltage drop, the batteries should be located as close to the Controller as possible.
Within 3 feet is ideal. If further than 3ft is required, the wires may be extended using appropriate
gauge cables. The batteries operate best at room temperature and it is best to keep them out of
freezing conditions for maximum performance.
Note: Do not exceed two 12V batteries in
series or four 6V batteries in series. For
extra battery capacity add sets in parallel.

AC INPUT (Only if Required)
Your Controller is designed to take solar power and charge your battery bank. As an optional
backup, it is also setup to accept 220V to both charge your batteries and run your pump directly
if desired. (15A breaker) AC input can be wired directly into the screw terminals of your
controller, by removing the front cover plate. On some models you may find a pre-wired plug.

PUMP MODES
MODE to select the working mode:
1. NORMAL (most common)
Increases the water pressure or draws water up
from below pump and pressurizes. This is the
normal booster pump application.
1.0 - 2.0 Low Pressure
2.0 - 3.0 Medium Pressure
3.0 - 4.0 High Pressure
1 kg/cm² = 14.5 psi
Note: Pump shutoff will become unstable if
pressure is set too high. If pump will not shut-off,
reduce pressure setting
2. BOOST
Increases poor water pressure. For example
increasing 20 PSI water pressure to 45 PSI on a the
second story of a house.
3. TIMER
Operates for the specified amount of time and then
stops the pump. Used for filling elevated tanks.
