Location determination in a photovoltaic system

A method, comprising:

• receiving, by a controller, a first communication current value from a first local management unit;
• wherein the first communication current value is calculated from a communication signal received at the first local management unit from the controller;
• receiving, by the controller, a second communication current value from a second local management unit;
• wherein the second communication current value is calculated from a communication signal received at the second local management unit from the controller;
• ordering, by the controller, the first communication current value and the second communication current value to form an ordered list;
• and
• storing the ordered list in a memory, wherein the ordered list represents a relative location of the first local management unit and the second local management unit compared to a transmitter in a photovoltaic system.

A method, comprising:

• determining, by a controller, a first signal strength value from a first local management unit, the first signal strength value representative of a signal strength for the first local management unit;
• determining, by the controller, a signal strength value from a second local management unit, the second signal strength value representative of a second signal strength for the second local management unit;
• ordering, by the controller, the first signal strength value and the second signal strength value to form an ordered signal strength list;
• storing the ordered signal strength list in a memory, wherein the ordered signal strength list represents a relative location of the first local management unit and the second local management unit compared to the controller;
• receiving a first communication current value from the first local management unit, the first current value representative of a first input communication current to the first local management unit in a photovoltaic system;
• receiving a second communication current value from the second local management unit, the second current value representative of a second input communication current to the second local management unit in the photovoltaic system;
• ordering, by the controller, the first current value and the second current value to form an ordered list;
• and
• storing the ordered list in the memory, wherein the ordered list represents a relative location of the first local management unit and the second local management unit compared to a transmitter in the photovoltaic system.
