Systems and methods relating to the conversion of DC power to AC power suitable for an AC power grid. DC power is received from one or more PV panels and is converted into DC power useful for charging an energy storage subsystem. The energy storage subsystem feeds into a DC/DC converter that converts the low voltage DC power into high voltage DC power suitable for a DC/AC inverter. The DC/AC inverter then converts the high voltage DC power into AC power suitable for an AC grid. A low voltage DC/DC converter can be used that is based on a differential geometry approach such that adjustable parameter values for components within the converter converge to nominal values as system parameters evolve.
