Abstract: Examples described herein include methods, techniques, and systems for designing and/or installing an off the grid energy solution. In some embodiments, a system includes a fuel station and a power station, where the fuel station is electrically, communicatively, and mechanically coupled to the power station. The power station may include a plurality of power generation and/or power storage methods, such as via a genset, solar panels, and/or a battery. These electrical power sources, combined with the fuel from the fuel station, contribute to the system being a dependable, standalone energy solution. The system may also utilize a network and a server, where the server comprises a system management module. The system management module may include a fuel management module, a fuel inventory module, and a system maintenance module.

Abstract: A mobile ultrasonic fuel detection system includes an ultrasonic sensor and a control unit. A control unit guard is included to protect the control unit from the external environment and to minimize tampering with the control unit. An activator arm may be included that permits a user to interact with the control unit from the exterior of the control unit guard. The system may also be configured to wirelessly provide measurement data from a remote location. Such data may be obtained manually or automatically according to a predetermined schedule.
