The SunWize™ Standby Power Systems are fully integrated and automated power packages. The systems are designed to maintain a home’s basic loads such as lighting, refrigeration, furnace fan, sump pumps and television for one to five days depending on user habits and conservation during power outages. When the utility is providing AC power to the inverter/charger, the system will act as a battery charger to keep the DC battery storage bank fully charged. When the primary source of AC power fails, the system becomes an inverter that converts the DC battery power into utility-grade AC power. The transfer is completely automatic.

The SunWize Standby Power Systems are capable of charging from solar-electric modules and/or a generator using an optional charge controller with a DC circuit breaker. The controllers use DC power from the solar modules to charge the battery bank. The controllers also protect the batteries against overcharging and automatically disconnect the solar array at night.

The SunWize Standby Power Systems are available in four models ranging from 3 kWhr - 31.4 kWhr battery capacity. The connections to the AC utility and AC load subpanel are made at the AC input/output/bypass breaker. The bypass breaker allows the inverter to be isolated from the AC source during maintenance service. The unit also features an AC lightning arrestor and an AC input surge capacitor. Please note that a licensed electrician must install the SunWizeò Standby Power Systems.

The battery bank of valve-regulated, deep-cycle, lead-acid batteries is separated from the inverter/charger by a 250A DC circuit breaker. The circuit breaker acts as a disconnect and protects against the extremely high battery currents in case of a short-circuit. A battery temperature sensor, included for installation within the battery bank, feeds a signal back to the inverter/charger to automatically adjust battery charge voltage. A 500A, 50mV shunt is also provided for battery current flow measurements.
