Patent number: 8922192Abstract: A method for multiphase electrical power phase identification by a monitoring component includes: receiving a request for the power phase identification for a given power component phase connection from a power component; in response, sending signal characteristics to the power component; monitoring power signals on distribution panel phase connections; determining that the signal characteristics are found on a given distribution panel phase connection; and in response, sending an identifier of the given distribution panel phase connection to the power component. In receiving the signal characteristics, the power component: selects the given power component phase connection; applies a signal with the signal characteristic on the given power component phase connection; receives an identifier of the given distribution panel phase connection from the monitoring component; and associates the identifier with the given power component phase connection.Type: GrantFiled: December 30, 2011Date of Patent: December 30, 2014Assignee: Stem, Inc.Inventors: David Erhart, Craig Southeren, Stacey Reineccius

Patent number: 8880233Abstract: A control system for an energy storage system located behind a utility meter uses a unique, feedback-based, communication and control method to reliably and efficiently maximize economic return of the energy storage system. Operating parameters for the energy storage system are calculated at an external, centralized data center, and are selected to prevent electrical power demand of an electric load location from exceeding a specified set-point by discharging energy storage devices, such as DC batteries, through a bidirectional energy converter during peak demand events. The control system can operate autonomously in the case of a communications failure.Type: GrantFiled: April 30, 2014Date of Patent: November 4, 2014Assignee: STEM Inc.Inventors: Ben Kearns, Jon Burlinson, Drew Stevens

Patent number: 8803570Abstract: In a multiphase electrical power assignment, a processor: receives instructions to connect a bi-directional power device to a multiphase premise power source; determines that the power device is to be coupled to a target phase's phase connection; confirms that the power device is not coupled to any phase connections; and couples the power device to the phase connection, where the power device's power signal is synchronized with the phase connection's power signal. When the power device is in a connected state, the processor: issues a command to place each phase connection switch in an open state; in response to confirming that the phase connection switches are in the open state, issues commands to the power device so that a power signal of the power device will be synchronized with the target phase; and closes the phase connection switch corresponding to the target phase.Type: GrantFiled: December 29, 2011Date of Patent: August 12, 2014Assignee: STEM, IncInventors: Lynn Smith, Stacey Reineccius
