An multi-mode system includes inverter/charger that is capable of interacting with the grid can integrate many different energy sources for energy storage charging, backup power, and energy management schemes. They can charge the energy storage system off of the grid, but can also be programmed to feed energy back into the grid if the energy storage system is full and there is excess energy that is not being consumed by loads. As these systems integrate PV, energy storage storage and the grid, they are rather complex and can require significant programming depending on the application. The two most common applications for a multi-mode system are for back-up power systems and for grid-tied systems in areas that offer very little compensation for excess energy feed back into the grid or prohibit the exportation of excess production. If very little compensation is offered to the user, then the inverter is typically set in an auto-consumption configuration, which prioritizes the local consumption of the energy generated by the PV array before any is exported. If exporting to the grid is prohibited, then the inverter can be configured into a zero sell configuration that will ensure that no energy is fed back into the grid.
