More Information
Summary:An apparatus provides homeowner selectable full or partial back-up power of a residential photovoltaic system to power critical loads during a utility power outage. A single split-bus electrical panel with a first panel section supplies utility power to non-critical loads and a second panel section supplies photovoltaic power to critical loads. A mechanical interlock in contact with interlocked circuit breakers of the first panel, prevents them from both being simultaneously on. A patch panel associated with the split-bus electrical panel enables an installer to selectively connect factory installed connections to either: connect the second panel section to utility power via a microgrid interconnection device when the second panel section is at least partially powered by back-up photovoltaic power, or connect the first panel section through one of the interlocked circuit breakers to utility power via the microgrid interconnection device to provide both panel sections with full back-up photovoltaic power.
