C: February 2001Page61OPERATING MODESThe SW Series Inverter/Charger can be used in a wide variety and combination of operating modes:• Inverter Mode - DC to AC inverter with sine wave output, high starting surge, power saving searchmode, low idle current, and very high efficiency DC to AC conversion.• Charger Mode - Low AC current distortion, three stage, temperature compensated, high amperagebattery charger.• Inverter/Charger Mode - Automatic transfer from inverter to battery charging upon presence of utilityor generator AC power source.• Generator Support Mode - Automatic “no glitch” switching from charger mode to inverter modeallowing the inverter to assist the generator in starting and powering large loads. Adjustable generatorsupport current and voltage thresholds.• Automatic Generator Control Mode - Automatic generator starting, based on the battery voltagereaching an adjustable voltage setting or the AC loads exceeding an amperage setting. Both startconditions include adjustable time delays. Once started, the inverter operates in battery charger modeuntil battery is charged to the float stage or until the AC load is reduced. The generator is then shut offand the loads are powered from the battery through the inverter. Automatic generator exercising of thegenerator and adjustable quiet time period to reduce generator operation may be programmed in thesetup menu.• Utility Backup Mode - Phase synchronized fast AC transfer switching for utility backup power supplyapplications. Includes adjustable AC transfer voltage and line conditioning ability.• Utility Interactive Mode - Excess power from charging sources or stored power from the battery canbe “sold” back into a utility grid. Also allows selling of the stored energy in the battery during a specifictime period.• Energy Management Mode - Onboard clock to set inverter and charger operating time periods. Thismode can be used with “time of day” metering to shift energy consumption to off-peak periods.• Peak Load Shaving Mode - Used to limit the draw of AC loads from a utility grid by powering it fromthe batteries. The batteries are recharged when the AC loads are reduced. This can “level” the loadon a utility.• Low Battery Transfer Mode - Automatic transfer of the AC loads from the batteries to the utility whenthe system reaches an adjustable low battery voltage setting. Independent settings allow control ofwhen the AC loads return to battery once it is recharged.Often, the inverter will be set-up to operate in several modes at the same or different times - such asoperating as an inverter/charger in utility back-up mode with automatic generator control mode andgenerator support mode during extended utility outage periods.ADDITIONAL FEATURESNumerous additional features are provided to enhance and customize the inverter's operation for thevarious operational modes:• Automatic generator control system with adjustable quiet time period to reduce generator operation.• Three-stage battery charging with fully adjustable charge settings and battery temperature sensing.• AC and DC voltmeters and AC ammeters to allow monitoring of inverter, generator, and utility grid.• On-board 24-hour clock for programming of generator quiet time and utility interactive modes.• Adjustable sellback current level for utility interactive mode.• Two separate AC inputs for utility and generator sources with utility priority.• Three independently adjustable auxiliary signal relays for controlling charging sources, loads etc.
