  Leverages existing UPS rectifier, inverter and charge controller Daytime battery charging to peak power voltage ( V s mp ) based on measured PV array's open circuit voltage ( V s oc ) from the series-connected SPV/ rectified wind generator. For wind speed  w   Nighttime wind-based load-support and battery charging (when wind speed exceeds 10m/s) Changes to the UPS to interface PV array and Smart Relay are simple and fail-safe Automatically switches in the appropriate power source (PV array/ Wind/ Utility) Minimizes power outage probability Maximizes expected solar and wind power utilization Minimizes expected grid power utilization Minimizes expected life cycle costs (including capital amortization, battery replacement and system maintenance) Diagnostics: Battery-operated hand-held PC may monitor PV/ Wind/ UPS performance (through isolated com-port) Faults that distort the Voc vs Vmp relationship are identified by monitoring Voc and Vdc time series Automatic over-voltage protection hardware (solid-state relay with manual reset). For example, a loose connection from the PV array/ Wind to the UPS's DC bus may be identified Smart relay may be upgraded for additional features (e.g., demand side management)
