Pump Power Dedicated or Integrated?

Pump Power Source - Dedicated or Integrated? 

A DEDICATED power system is one which supplies power only to the pump. An INTEGRATED system is one in which the pump is wired to the home power system. Lets examine these two methods. Dedicated System Wire for low voltage power transmission must be relatively large (expensive) to minimize power loss. If the distance from your home's power center to the well and down to the pump is more than 200 feet, the expense may be high. A dedicated system may be cheaper, particularly if batteries are eliminated. Price it out both ways and compare. The dedicated system gives the water system its own power supply divorced from the consumptive vagaries of the main home power system. This means that the energy used to supply water is not shared with other appliances like TVs, lights and what-not.

Using a dedicated system also allows installation of a solar water pump that is totally independent of utility power, allowing water pumping even if grid power is down. Integrated System Connecting the pump to the home power system has advantages. Wired in this way, it is simply one of the home's appliances. During the summer, a home with photovoltaic power tends to produce excess energy. This energy can be put to work watering your land. A controller may be set up to do this automatically when your battery bank approaches full charge. The home's battery system and backup generator also provides an energy reserve that can be applied to pumping. In integrated system is more versatile and cheaper than adding a dedicated system, if your well is not too far from your power source. Powering the pump from the main system's batteries also allows use of the well pump to pressurize the water system if necessary.
