## 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

### Claim 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.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 1)

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

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 1)

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.

### Claim 6 (depends on 1)

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

### Claim 7 (depends on 6)

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.

### Claim 8 (depends on 6)

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

### Claim 9 (depends on 1)

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.

### Claim 10

A portable hybrid generator system comprising:
