Storage battery monitoring system with automatic electrical load shedding

A method for controlling the electrical system of a marine vessel, comprising the steps of:

• measuring the voltage potential of a battery;
• comparing said voltage potential to a threshold voltage magnitude;
• and
• disconnecting one or more of a plurality of electrical power consuming devices when said voltage potential is less than said threshold voltage magnitude;
• measuring the operating speed of an engine of said marine vessel;
• comparing said operating speed of said engine to a threshold speed magnitude;
• and
• performing said disconnecting step only when said operating speed of said engine is less than said threshold speed magnitude.

• measuring the voltage potential of a battery;
• comparing said voltage potential to a threshold voltage magnitude;
• communicating to an operator of said marine vessel information that said voltage potential being less than said threshold voltage magnitude;
• disconnecting one or more of a plurality of electrical power consuming devices when said voltage potential is less than said threshold voltage magnitude unless said operator of said marine vessel manually overrides said disconnecting step;
• measuring the operating speed of an engine of said marine vessel;
• comparing said operating speed of said engine to a threshold speed magnitude;
• and
• performing said disconnecting step only when said operating speed of said engine is less than said threshold speed magnitude.
