PP600H AC PowerPack
Manual
AC/DC converter to power PS200/PS600/EP600
pump systems from a generator or utility power
for PS1200/PS1800: see end of manual
Application
The Problem
Some solar pumps may not provide sufficient flow under all
conditions, especially in unusually cloudy weather or when
sufficient storage cannot be provided.
The Solution
LORENTZ AC PowerPack allows the pump to be powered
by an AC generator or commercial utility power. The solar
array remains connected. If the sun comes out again, less
power is drawn from the AC source.
A common application is for a portable genset (gasoline
generator) to run a well pump. When the generator is
stopped (or runs out of fuel) the pump automatically re-
turns to solar power when the sunshine is sufficient. No
manual switching is required.
The PowerPack will power the pump to its full capacity.
With some systems, it will produce a greater flow rate than
you will see with solar power.

Warranty
Warranted to be free from defects in material and work-
man-ship for TWO YEARS from date of purchase.
WARNING Power Pack must be OFF
while it is being wired to the solar
pump controller, or controller damage
may result. Never connect it while it is
“hot”.
Wire Sizes
All wires must be #14 AWG (2.5 mm2) or larger.
AC Input Voltage Selection
Selection must be made by connecting a wire from terminal
1 to either 2 or 3, as indicated on the terminal label. For
115VAC, connect 1-2. For 230VAC, connect 1-3.
Grounding
Bond the metal enclosure to the ground connections of
the AC power source and the solar power system. See your
pump’s instruction manual.
AC Power Source
Install a 15A circuit breaker at the power source or distri-
bution box.
INSTRUCTIONS
Installation
WARNING This device is to be in-
stalled, connected and serviced by
qualified personnel only. Ensure all
power sources are disconnected when
making connections to this unit. Follow all appro-
priate electrical codes. There are no user-servicea-
ble parts inside.
Mounting
Mount the AC PowerPack close to the pump controller, in
a vertical position. Cover the unit from direct rainfall. You
will find four mounting brackets in a plastic bag inside the
enclosure.
WARNING PowerPack must be protect-
ed from solar heat, especially direct
mid-day sun. Mount it in the shade. If
there is no shady location, make a
shade from sheet metal. Allow free air circulation
around the cooling fins on the back of the enclo-
sure. For wall mounting, use spacers to stand it out,
so the cooling fins do not touch the wall.

DC Output Voltage Selection
Selection must be made by connecting a wire from termi-
nal 6 to either 4 or 5, as indicated on the terminal label.
For 75V DC, connect 4-6 (for PS200/PS600/EP600). For
110V DC, connect 5-6 (for PS1200).
AC Input
Connect AC power to terminals L and N. (For a 230V con-
nection, N does NOT indicate neutral.)
Solar Power In
Connect the + and – wires from the solar array disconnect
switch to the SOLAR POWER IN terminals. If the solar pump
was previously installed without this device, the wires will
need to be removed from the POWER IN terminals of the
solar pump controller or from the disconnect switch, and
diverted to the Power Pack.
DC Power Out
Connect two wires from the DC POWER OUT + and – ter-
minals to the POWER IN + and – terminals in the solar
pump controller.
Internal Fuse
There is a 10A fuse in the upper left. This fuse should blow
only if there is an electrical fault in the PowerPack, or the
pump controller, or the wiring between them. It will NOT
blow if the pump is short-circuited or overloaded. (In that
case, the pump controller will stop the pump.)
Spare fuses are included in the parts bag. Additional fuses
are available from electronic suppliers (5 × 20mm, 10A,
time-delay). If the fuse continues to blow, the fault must be
found and repaired. Substitution of a higher-rated fuse or
bypassing the fuse will void the warranties of both the AC
PowerPack AND the pump controller.

Operation
Connect the AC power source and turn on the Power
Pack AFTER it has been connected to the PS200/PS600 or
EP600 series controller. When the controller and the Power
Pack are turned on, the System ON light should show on
the cont-roller, and the pump should start. When the Power
Pack is turned OFF (or its AC source disconnected), the so-
lar array will remain connected. When the pump is running
on solar and the Power Pack is switched ON or OFF, the
sudden transition may “surprise” the pump controller and
cause the pump to stop. This is not a fault. It will restart
automatically in about 2 minutes.
If the AC power source is from the utility line (not a genera-
tor), it is best to turn OFF the PowerPack or its AC supply
when it is not needed. Otherwise, the PowerPack will draw
a small amount of power all the time. Switching can be
done automatically using a timer switch on the AC line.
Timer switches of many kinds are available from suppliers
of electrical, swimming pool and irrigation equipment.
Once the PowerPack is turned OFF it will take up to 50 sec-
onds for the POWER ON LED to be OFF. This indicates that
there is still voltage stored in the capacity.
Applicability for Other Systems
PS1200 Pump Systems
Use two sets of PP600H PowerPack wired in parallel for all
centrifugal pumps used with the PS1200 pump system. The
centrifugal pumps draw more power then the one single
powerpack is able to handle. HR pump systems are not ef-
fected by this.
PS1800 Pump Systems
Use two of this power pack wired in parallel or use the
larger PP2000 PowerPack.
