1. A system for producing electrical power to a load, comprising:
- a) a first bank of batteries;
b) a second bank of batteries;
c) an inverter bank for producing ac;
d) a switch that alternately connects one of the first or second battery banks to the load and to the inverter bank with the other of the first and second battery banks being disconnected from the load and the inverter bank;
e) a motor connected to the inverter bank;
f) an alternator bank powered by the motor, the alternator bank having an electrical output that is connected to the other of the first and second battery banks;
g) a timer connected to the switch, the timer periodically switching the switch;
h) a motor controller connected between the inverter bank and the motor, the motor controller regulating the speed of the motor;
i) the inverter bank produces three phase ac, the motor is a three phase motor.

Abstract
A system and method produces electrical power for a load. First and second battery banks are provided, as is an inverter bank, which produces three phase. A switch alternately connects one of the first or second battery banks to the load and to the inverter bank with the other of the first or second battery banks being disconnected from the load and the inverter bank. A motor is connected to the output of the inverter bank. The motor drives an alternator bank, which alternator bank is electrically connected to, and recharges, the other of the first or second battery banks. A timer periodically alternates the battery banks between a load mode and recharge mode.

8. A method of providing electrical power to a load, comprising the steps of:
-
a) providing first and second battery banks; b) connecting one of the first or second battery banks to the load, with the other of the first or second battery banks being unconnected to the load, the load comprising an inverter bank; c) producing three phase ac from the inverter bank; d) driving a three phase motor with the ac; e) regulating a speed of the motor with a motor controller; f) driving at least one alternator with the motor to produce electricity; g) using the alternator to recharge the other of the first or second battery banks; h) using a timer to switch connecting and unconnecting the first and second battery banks to the load and the alternator. - View Dependent Claims (9)
