A client-server network environment is temporarily transformed into a grid computing environment through the deployment of a network-booted grid operating system to each of a plurality of network clients. Each participating client operates in the client-server mode under a local operating system. At an appropriate time, a server transmits to each client a thin-client boot image (a dynamically built customized image or an image obtained from a store of predefined boot images) along with a grid application for which the thin-client has been optimized for peak performance. Each client re-boots using the thin-client image, thereby entering the grid mode and allowing substantially all of its computing resources to be dedicated to executing the grid application. At a later time, the server directs that each client terminate the grid application and re-boot in its respective local operating system, reverting again to the client-server mode.

This invention presents a highly efficient harmonics free DC-AC power inverter using a pair of push-pull switches with feedback loop that acts as a voltage regulator. The feedback loop voltage regulator uses a series-shunt feedback amplifier to regulate the output voltage by amplifying the error signal between a pure sine wave referenced signal and the measured output voltage signal. A step-up low power transformer is used to step-up the triggering pulse at gates of the push-pull solid state switches to the desired rated output voltage so that the output voltage becomes harmonic free sine wave, but high voltage feedback amplifier, if feasible, maybe used without using the transformer. The reference signal may be synchronized with the grid for on grid applications, but it can also be used for stand alone loads. In order to optimally minimized the conduction power loss across the push-pull solid state switches of the DC-AC inverter, the positive voltage V+ and the negative voltage V− must be regulated and controlled, so that the voltage across the push-pull switches are minimized. Hence, two DC-DC converters are used to generate the regulated voltages V+ and V−. Each of those voltages is controlled using a feedback loop that drives the pwm of the DC-DC converter. At this point, the conduction power loss of the DC-AC push-pull solid state switches are optimally minimized, but the DC-DC converters are not. In order to minimize the conduction power loss of the DC-DC converters, two multilevel converters with n-array series voltage sources, or n-array series capacitors, are used. The voltage level at the top of each capacitor is carefully selected so that the overall conduction power loss of the DC-DC converters is minimized. The power conduction power loss proportional to the number of levels used but this comes at higher cost and complexity.

The method comprises the steps that: an independent power loop connected with a photovoltaic panel to form a photovoltaic loop is set, and an independent charge and discharge loop connected with a battery to form a charge loop and a discharge loop is set; the voltage of a bus is detected; when the voltage of the bus is larger than the upper limit of a control reference voltage of an off-grid system, a photovoltaic energy storage inverter stops the MPPT control over the photovoltaic panel, the voltage of the bus is stabilized to the control reference voltage of the off-grid system, and the discharge loop of the battery is switched off; when the voltage of the bus is lower than the lower limit of the control reference voltage of the off-grid system, the photovoltaic energy storage inverter starts the MPPT control over the photovoltaic panel, the PV voltage of the photovoltaic panel is controlled to a photovoltaic maximum power point, and the battery is controlled by the discharge loop to carry out discharging; or else, the off-grid system maintains the current work state. By applying the method, the photovoltaic off-grid application power configuration restriction and the photovoltaic utilization rate are greatly improved, and the photovoltaic application stability in a district without a power grid is realized.
