Normal submersible well pumps are 120 or often 240 volts pumps that can use very large amounts of electricity and have a big power serge requirement when the motor starts up. This serge is important because it is often so large that many inverters (in an alternative energy system) cannot handle it. Here is where the "soft start" feature fits in. It is more efficient than regular pumps and features a "soft start" which avoids the large serge of power when the pump turns on. These pumps can be run on an alternative energy systems which makes it an excellent option for those with a well who want to be free from dependence on utility companies. One of the best options in this class is the SQ series, made by Grundfos . Regular 120 volts AC submersible pumps may be used as long as you are certain your inverter can handle the serge requirement of the pump motor. 240 volts pumps should generally be avoided when using an alternative energy system with a battery bank because the inverter that converts the DC electricity in the batteries to AC electricity normally does not supply 240 volts.
