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 (gaso- line generator) to run a well pump. When the generator is stopped (or runs out of fuel) the pump automatically returns 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.

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 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.
