1. A control device for controlling an energy storage system comprising an energy storage device, a bidirectional AC/DC converter, and a grid connection to an electrical power distribution grid, the control device including:
a processor;
an external memory interface configured to read external software instructions from an external removable memory device;
a control interface configured to control the energy storage system;
a user interface device comprising a screen, the screen comprising a first subset of screen space and a second subset of screen space; and
an internal memory storing internal software instructions that, when executed by the processor, cause the processor to:
provide access to only the first subset of screen space for the external software instructions;
read the external software instructions from the external removable memory device; and
execute the external software instructions to cause the control interface to:
control power on the grid connection to be within a predetermined range of a target value;
store power on the energy storage device in response to a first control parameter comprising at least one of an energy usage value, an energy cost value, or a power outage condition value; and
consume power from the energy storage device in response to a second control parameter comprising at least one of an energy usage value, an energy cost value, or a power outage condition value.
