SW Series Inverter/Charger
Part No. 2031-5
Rev. C: February 2001

OPERATING MODES
The 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 search
mode, low idle current, and very high efficiency DC to AC conversion.
•
Charger Mode - Low AC current distortion, three stage, temperature compensated, high amperage
battery charger.
•
Inverter/Charger Mode - Automatic transfer from inverter to battery charging upon presence of utility
or generator AC power source.
•
Generator Support Mode - Automatic “no glitch” switching from charger mode to inverter mode
allowing the inverter to assist the generator in starting and powering large loads. Adjustable generator
support current and voltage thresholds.
•
Automatic Generator Control Mode - Automatic generator starting, based on the battery voltage
reaching an adjustable voltage setting or the AC loads exceeding an amperage setting. Both start
conditions include adjustable time delays. Once started, the inverter operates in battery charger mode
until battery is charged to the float stage or until the AC load is reduced. The generator is then shut off
and the loads are powered from the battery through the inverter. Automatic generator exercising of the
generator and adjustable quiet time period to reduce generator operation may be programmed in the
setup menu.
•
Utility Backup Mode - Phase synchronized fast AC transfer switching for utility backup power supply
applications. Includes adjustable AC transfer voltage and line conditioning ability.
•
Utility Interactive Mode - Excess power from charging sources or stored power from the battery can
be “sold” back into a utility grid. Also allows selling of the stored energy in the battery during a specific
time period.
•
Energy Management Mode - Onboard clock to set inverter and charger operating time periods. This
mode 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 from
the batteries. The batteries are recharged when the AC loads are reduced. This can “level” the load
on a utility.
•
Low Battery Transfer Mode - Automatic transfer of the AC loads from the batteries to the utility when
the system reaches an adjustable low battery voltage setting. Independent settings allow control of
when 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 as
operating as an inverter/charger in utility back-up mode with automatic generator control mode and
generator support mode during extended utility outage periods.
ADDITIONAL FEATURES
Numerous additional features are provided to enhance and customize the inverter's operation for the
various 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.
