Abstract: A solar system installed at a house or building, which may include solar panels and a solar inverter. When the solar system is installed at the house or building, the power load associated with the solar system might overload an electrical panel. This might force the owner of the house or building to spend thousands of dollars on an electrical panel upgrade. To avoid such an expensive upgrade, a smart load manager (SLM) is disclosed that can communicate with the solar inverter and can control it. The SLM can function as a real-time load shedding device, thereby avoiding the cost of a load center/panel upgrade, while enabling a safe and cost-effective solar system installation.
