1. A storage system configured for use with an energy management system, comprising:
a single-phase AC coupled battery or a three-phase AC coupled battery;
a plurality of microinverters that are configured to connect to one or more battery cells that form a local grid;
a server-based system configured to provide:
an estimator tool for storage system sizing and photovoltaic sizing; and
at least one of configurable single-phase AC coupled battery and three-phase AC coupled battery profiles to optimize at least one of self-consumption or time-of-use; or
troubleshooting capabilities to identify and fix issues with the energy management system; and
a controller configured to detect when to charge or discharge the single-phase AC coupled battery or the three-phase AC coupled battery so that energy can be stored therein when energy is abundant and used when energy is scarce,
wherein the plurality of microinverters are field swappable such that the plurality of microinverters configured for use with the single-phase AC coupled battery are also configured for use with the three-phase AC coupled battery.
