Abstract: Bypass systems can be used to connect alternative energy sources to existing distribution panels without the need to replace or upgrade the distribution panel. Some such bypass systems may be integrated directly into an electric meter, while others can be connected to the meter but located laterally or otherwise away from the electric meter. The bypass busbars and breakers may in some devices be interchangeable, allowing for greater flexibility and capacity of the bypass systems.
