THE PROBLEM
Some solar pumps may not provide sufficient flowduring all conditions, especially in unusually cloudyweather or if sufficient storage is not provided.
THE SOLUTION
The Lorentz AC Power Pack allows the pump to be powered by an AC generator or commercial utility power. When the Power Pack or its AC supply is turned off, the solar array again supplies the power. The transfer is automatic.A common application is for a portable gasoline generator to run a Lorentz well pump. When the generator is stopped (or runs out of fuel) the pump returns to solar power. The AC Power Pack will power the pump to its fullpotential flow rate, as indicated on the Lorentz pump performance table for 600 watt systems. In a lower power system, AC Power Pack will produce a greater flow rate than solar power.
