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
The LORENTZ PowerPack PP600H AC allows the pump to be
powered byan AC generator or mains supply.
The solar array remains connected while the PowerPack acts
as a changeover switch between the two power sources.
As soon as backup power is required the PowerPack can be
switched on to bypass the solar generator and supply the
pump from the auxiliary power source. The changeover from
solar is done automatically after switching on the power
supply for the PowerPack.
For a scheduled use of the PowerPack (e.g. to extend pump-
ing time) a seperate time switch can be used to control the
power supply to the PP600H. If the auxiliary power source is
switched off again the PowerPack automatically returns to
solar-direct operation.
The PowerPack is able to power the pump to its full capac-
ity.

INSTRUCTIONS
Installation
WARNING This device is to be installed,
connected and serviced by qualified
personnel only. Ensure all power sourc-
es are disconnected when making con-
nections to this unit. Follow all appropriate electri-
cal codes. There are no user-serviceable parts
inside.
Mounting
Mount the 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 en-
closure (see figure 1 and 2).
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.
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 (2.5mm2) 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
120VAC, connect 1-2. For 240VAC, 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 distribu-
tion box.
AC Input
Connect AC power to terminals L and N. (For a 240V 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 – termi-
nals to the POWER IN + and – terminals in the solar pump
controller.
Internal Fuse
There is a 15A 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× 20 mm, 15A,
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 pump controller. When
the controller and the Power Pack are turned on, the Sys-
tem ON light should show on the controller, and the pump
should start. When the Power Pack is turned OFF (or its AC
source disconnected), the solar 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
power all the time. Switching can be done automatically us-
ing 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 capacitor.
