According to one aspect, embodiments herein provide a power converter configured to monitor at least one of current and voltage at a bidirectional AC load terminal, determine, based on the monitoring, whether the power converter is receiving AC power from at least one Photo-Voltaic (PV) inverter or whether AC power is being drawn from the power converter by at least one load, determine whether an energy storage device coupled to the power converter is fully charged, and in response to a determination that the power converter is receiving power from the at least one PV inverter and a determination that the energy storage device is not fully charged, operate a power conversion unit in the power converter to convert the AC power received from the at least one PV inverter into DC power and provide the DC power to a bidirectional DC terminal to charge the energy storage device.

Self regulated power converter

A method of charging a battery in a system involving a renewable energy source and operable to supply at least some electrical energy from the renewable energy source to a third party involves causing a charge controller operably connected to the renewable energy source to receive the electrical energy from the renewable energy source and operably connected to the battery, to charge the battery, using only the electrical energy from the renewable energy source, according to a charging sequence. The charging sequence includes at least a bulk charge period wherein the battery is charged at a relatively constant charging current, an absorption period following the bulk charge period wherein the battery is charged in an absorption mode, and a float period following the absorption period wherein the battery is charged in a float charging mode.
