Some solar pumps may not provide sufficient flow under all conditions, especially in unusually cloudy weather or when sufficient storage cannot be provided.
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 pumping 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 capacity.
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 System 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 generator),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 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 seconds for the POWER ON LED to be OFF. This indicates that there is still voltage stored in the capacitor.
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 120 V AC, connect 1-2. For 240 V AC, connect 1-3.
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 15 A circuit breaker at the power source or distribution box.
Connect AC power to terminals L and N. (For a 240 V connection, N does NOT indicate neutral.)
Solar Power In
Connect the + and – wires from the solar array disconnect switch to the SOLAR POWER IN terminals. 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 – terminals to the POWER IN + and – terminals in the solar pump controller.
There is a 15 A 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, 15 A, 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.
