In some embodiments, apparatuses and methods are provided herein useful to operating uninterruptible power supplies (UPS). The embodiments may include a plurality of capacitor banks, a UPS control circuit, and a central control circuit. The UPS control circuit is configured to cause an output of a clean electrical power, sample the clean electrical power, calculate control algorithm outputs based on the sampled clean electrical power, and output control algorithm results to the central control circuit. The central control circuit configured to detect a degradation of the plurality of capacitor banks, and transmit a service alert in response to the detection of the degradation of the plurality of capacitor banks.

Systems and methods for operating an uninterruptible power supply (UPS)

A system and method is disclosed for analyzing a set of collected raw data point values and determining which one or ones of the values are erroneous data values. In one implementation of the method specific ones of the values are examined to determine if they are outliers, and if so they are removed from the data set. At least two other ones of the values obtained at points in time prior to a given one of the values are examined. Weights may be assigned to the at least two other values, and the weights used to help generate a predicted data point value. The predicted data point value is compared to the given one of the values to determine if the given one of the values is an erroneous value. In this way the integrity of each data point value in the set can be checked.

System and method for UPS battery monitoring and data analysis

A system including a transceiver that is in a first device and receives wirelessly or over a powerline and from a second device, (i) a voltage value of a voltage detected between bus bars of a power source, where the power source supplies power to a load, and where the load is distinct from the first and second devices, or (ii) a current value of a current detected by a current sensor and drawn from the power source by the load. A sensing module one of (i) if the transceiver receives the current, detects the voltage and timestamps the voltage value with a first timestamp, and (ii) if the transceiver receives the voltage, determines the current and timestamps the current value with a second timestamp. A parameter module determines a parameter of the load based on the voltage, the current, and the first and second timestamps.

Mesh network synchronous power monitoring systems and methods

The present invention is related to user managed power systems with security. The invention encompasses a method and system of managing a power system wherein a data center user determines whether there is a desire to control remote power supply socket assigned to the user's data module. The data center user is able to sign into the remote power supply through a security protocol. Then the data center user can gain control over the remote power supply socket assigned to the user's data module. Finally, this allows the data center user to remotely control the power supply socket assigned to the user's data module.

User managed power system with security

The present invention is related to a method and apparatus for monitoring and controlling devices comprising connecting an external manager to a communication protocol, connecting a first device to the external manager, assigning an IP address to said first device publishing a second IP address from the first device, connecting a second device to said first device such that it obtains the said second IP address, publishing a third IP address from said second device.
