UNIT IDENTIFICATION
This section describes the marking and location of the model and serial numbers for SW Series
Inverter/Chargers. Use this section to determine the type and model of your inverter/charger. The unit
identification label on the left side panel of the inverter/charger will show the serial number, model
number, listings, ratings, and date of manufacture.

MODEL NUMBER
The Model Number of your inverter determines the different features your unit may have. Consider the
following unit with a SW4024 model number:
SW 40 24 *
Model Power Nominal DC
Voltage
AC Voltage/Options
Model: The first letter(s) (SW) indicate the model, in this case the SW Series.
Power: The first and second positions in the model number indicate the continuous AC power output in
hundreds of VA (Volt-Amps). Power levels available start at 2500 up to 5500 Volt-Amps with different DC
voltages. In the example above, 40 would stand for a 4000 VA (4 kVA), continuous-output inverter.
Input/Output DC Voltage: The number (24) following the power rating indicates an inverter/charger that
is designed to convert 24 VDC input to an AC voltage
output, and charge 24 VDC batteries when
powered by the same AC voltage. Available DC voltages are 12, 24 and 48 volt models.
Input/Output AC Voltage/Options: The letter following the power rating indicates what AC voltage and
frequency or particular option this inverter/charger is specifically designed to provide. No letter after the
DC voltage number indicates an AC voltage of 120 VAC/60 Hz and requires the same AC voltage and
frequency (120 VAC/60 Hz) to charge the inverter batteries. Available voltages range from 105 to 240
VAC at 50 or 60 Hz.
