Abstract

A portable hybrid generator may comprise a sturdy portable housing configured for easy movement and transport, an inverter for managing renewable and non-renewable energy sources, one or more batteries with or without a battery management system, one or more solar panels and solar panel combiner box, a communications systems, and a generator. In some instances the portable hybrid generator may comprise a communications system equipped to simplify the usage, maintenance, and control of the portable hybrid generator.

Claims (36)

1. A portable hybrid generator comprising:

a housing;

a lid coupled to a top portion of the housing, the lid providing selective access to an interior of the housing;

a frame extending around the housing, the frame having a plurality of handles extending above the lid, the portable hybrid generator weighing less than 100 pounds such that the plurality of handles are configured to facilitate manually transporting the portable hybrid generator;

a primary energy source disposed within the interior of the housing, the primary energy source including an engine, a fuel tank, and a generator;

an energy storage device disposed within the interior of the housing and electrically coupled to the primary energy source, the energy storage device including at least one battery;

an interface positioned along an exterior of the housing, the interface including an input port coupled to the energy storage device and an output port electrically coupled to at least one of the primary energy source or the energy storage device, the input port configured to facilitate connecting the energy storage device to a solar panel; and

a controller configured to:

receive information from the primary energy source and the energy storage device;

use the information received from the primary energy source and the energy storage device to estimate a power output for the portable hybrid generator according to a usage mode selected from a plurality of usage modes; and

control the power output of the portable hybrid generator based on the usage mode.

2. The portable hybrid generator of claim 1 , wherein the primary energy source comprises a maximum power-point transfer charger.

3. The portable hybrid generator of claim 1 , wherein the energy storage device is detachable from the portable hybrid generator.

4. The portable hybrid generator of claim 1 , wherein the usage mode is set by a local user interface or an application run on a mobile device in wired or wireless communication with the controller of the portable hybrid generator.

5. The portable hybrid generator of claim 1 , wherein the controller is configured to provide users with a plurality of options for the plurality of usage modes comprising one or more of the following: an automatic starting and stopping mode, a mode for maintaining maximum power of the primary energy source, or a mode for maintaining maximum efficiency of the primary energy source.

6. The portable hybrid generator of claim 1 , wherein the controller or a display is configured to provide users with automated maintenance procedures and notifications.

7. The portable hybrid generator of claim 6 , wherein the automated maintenance procedures comprise disabling a fuel line of the portable hybrid generator and running fuel out of a carburetor of the portable hybrid generator.

8. The portable hybrid generator of claim 6 , wherein the automated notifications comprise providing a status of oil, fuel, or other consumable component.

9. The portable hybrid generator of claim 1 , wherein the primary energy source comprises a choke valve that is controllable to allow a choke to open fully, open partially, or be completely closed.

10. A portable hybrid generator system comprising:

a first unit including:

a first housing;

a first input port configured to facilitate connecting a solar panel to the first unit;

a first output port; and

a primary energy source disposed within the first housing and electrically coupled to the first output port, the primary energy source including an engine, a fuel tank, and a generator driven by the engine;

a second unit separate from the first unit, the second unit including:

a second housing;

a second input port;

a second output port; and

an energy storage device disposed within the second housing and electrically coupled to the second input port, the energy storage device including at least one battery, wherein the second input port and the first output port facilitate selectively electrically coupling the first unit to the second unit to charge the energy storage device using energy generated by at least one of the generator or the solar panel, and wherein the second unit can be selectively decoupled from the first unit and transported to a location remote from the first unit to transfer power to an external device via the second output port using stored energy in the energy storage device; and

a controller configured to:

calibrate the primary energy source to the energy storage device; and

control a power output of the primary energy source based at least in part on the calibration of the primary energy source to the energy storage device.

11. The portable hybrid generator system of claim 10 , wherein the controller is configured to:

receive a selection of a usage mode of the portable hybrid generator system; and

control the power output of the portable hybrid generator system based on the selection and the calibration.
