NOVELTY - The system (200) has power-generators (PG) coupled to a direct current (DC) bus (205). Power-consumers (PC) are coupled to the DC bus, where the floating DC bus includes operating voltage that is varied over a range from minimum bus operating voltage up to maximum safe bus voltage, and variation in the operating voltage of the DC bus controls operation of the one power-generator or the power-consumer based on a control voltage range (CVR) of the power-generator or the power-consumer, where the operating voltage range transitions at common threshold voltage.    USE - System for integrating foldback-limited alternative-energy power-generators e.g. uncontrolled-energy power-generator (UEPG) such as solar panel, wave-powered generator and wind-powered generator, and controlled-energy power-generator (CEPG) such as fuel-cell power-generator, battery backup power-generator, grid-rectified power-generator, rectified alternating current (AC) power-generator, fossil-fuel power-generator and nuclear-powered generator.    ADVANTAGE - The system distributes electrical or electronic control throughout the generation system, so that power generation is optimized for a given application, and the energy-generating device is operated optimally and complexity of the associated electronics is minimized. The system allows a power consumption profile of the PC to be gradual to provide damping and prevent bouncing, oscillations, or other instabilities in the system. The system allows battery charger to include internal circuitry that can dynamically vary the CVR start-point and stop-point values and the load drawn from bus for backup battery, so that backup battery approaches a full charge, less current to be drawn from bus and current is only drawn at higher bus voltage to match the slower charge rate, higher internal batter voltage, or to prevent overcharging.    DETAILED DESCRIPTION - The power-consumers are grid-tie inverter power-consumers (220-B). An INDEPENDENT CLAIM is also included for a method for integrating and managing power-generators on a DC bus.
