Thank you for purchasing the finest sine-wave inverter in the power
conversion industry. The journey to excellence includes the
first affordable sine wave inverter, first modular inverter system, first
N+1 redundant inverter system, and the cleanest sine wave output
in the industry. We strives to manufacture products of the
highest possible quality, and is dedicated to 100% customer
satisfaction. Proudly built in the USA with American parts,
Committed to TL 9000 standards and beyond, adding people and
procedures continually to further improve quality and customer
service.
XP series inverters provide the cleanest, best regulated sine wave
output over the widest DC input of any inverter on the market today.
They are extremely low in Total Distortion; specified to 2%, and
typically better than 1.5%. Total Harmonic Distortion is typically 0.8 to
0.9%. Remaining distortion is a result of residual switching noise,
which amounts to a very clean 25 KHZ sine wave superimposed on
the fundamental output. No significant harmonics of 25 KHZ exist.
This spectral purity will exist over the inverter's entire operating
envelope, including non-linear and reactive loads. As long as peak
output current remains less than 300% of rated current, total harmonic
distortion will remain within the 2% spec. Peak current capability of the
inverter is key to understanding it's operational envelope. As long as
the inverter is supplying less than this amount, it will function properly
and operate virtually any load.
Many inverters are rated in Volt-Amps (VA), as opposed to Watts.
This is in an attempt to make an inverter or UPS (Uninterruptible
Power Supply) appear larger than it really is. The only fair way to

specify these products is in Watts (W), which is power the inverter
can actually deliver. If the XP inverters were specified in VA, Our
1100 Watt inverter could be rated at 1375 VA at .8 power factor,
1570 VA @ .7 pf, or an incredible 2200 VA @ .5 pf. It is confusing to
specify a product in VA, because the power factor must also be
specified. XP-Series inverters can output their full rated
oo
power continuously at 40 C
The inverter can maintain a spectrally pure output with any load, due
to a specially designed non-linear control loop in the primary DC to
DC converter. This circuitry is one of three circuits which protect the
inverter from any overload condition.
.
.
.XP-600 and XP-1100
These inverters can supply twice their rated output power for 3
seconds, in order to start motors or supply in-rush currents to
electronic loads. If output power is exceeded for greater than 3
seconds, output voltage is reduced to a level which will provide
the inverter’s rated power to the load by clipping tops of the
waveform. The inverter can operate safely in this mode indefinitely.
Should the overload condition clear, the inverter will again provide
the cleanest Sine Wave in the industry. This over-current circuitry
insures maximum peak current does not exceed 300% of rated
RMS current. Should this number be exceeded, it will again reduce
output voltage as required to maintain that limit. Again, the inverter
can operate in this mode indefinitely, so that when the overload
clears, output voltage is automatically restored. The third protection
mechanism is short circuit. If the inverter exceeds it’s peak current
(Ip) capacity for a prolonged period, it will shut off automatically. The
period of time required to shut off changes with the degree of
overload. A high overload shuts off in one second. A slight overload
may require several seconds. This typically requires a .5 ohm load
per 1000 Watts, for several seconds. This guarantees the inverter is
disabled, in the event that the user attempts to clear the short
without first shutting off the inverter. The inverter in fact, acts as an
extremely high performance circuit breaker. The short circuit and
overload circuitry responds much faster than any normal fuse or
breaker, so no external current limiting devices are necessary.
XP-Series inverters can output their full rated power
continuously at 40o C.The inverter is derated 20% of its

located on front panel; turns the inverter on and
off.
If input voltage to the inverter
exceeds set limits, the inverter will immediately and without warning
shut off. When input voltage returns to normal range, the inverter will
immediately restart. Since high over voltages tend to have very fast
edges, the inverter must shut down quickly to protect itself. This kind
of fault usually occurs if the battery is suddenly disconnected from
the system and the battery charger continues to supply current.
When battery voltage falls to
within 2% to 4% of low line voltage, the LOW BATT / THERM buzzer
will sound. If the condition continues without reducing load to the
inverter or adding charge to the battery, the inverter will shut off.
When voltage rises to approximately 95% of nominal battery
voltage, the inverter will turn back on and the alarm condition will
clear. The inverter can be manually reset by cycling the on/off
switch. This will reset the protection circuit and turn the inverter
on at any voltage above minimum voltage.
The inverter is also
protected against overheating. It will provide its full rated output up
to the temperature listed in the specification sheet. If it is subjected
to higher ambient temperatures or air circulation is blocked, the
inverter may overheat. If the LOWBATT/ THERM buzzer sounds,
immediate action is required or the inverter will shut down. Either
reduce load, or provide more cooling in the immediate environment.
If no action is taken, the inverter will likely shut down within 2
minutes. When the inverter shuts down, the alarm condition will
persist and the cooling fan will continue to run. Since the inverter
has eliminated its load, it will cool fairly quickly. It will automatically
restart when it has cooled sufficiently, and the LOW BATT/THERM
alarm will clear. “105 C internal temperature. Warning buzz 5 C

protection circuit will recover instantly when the overpower condition
clears. The third, is short circuit protection. If the over current
condition is so severe that it causes output voltage to collapse to 1
Vp for more than 1 second, the inverter will shut down and not auto-
matically restart. This requires the user to clear the short circuit
safely, and guarantee that hazardous voltage will not come back on
line until desired. To reset the inverter from this condition, cycle
power switch “OFF” then “ON” again. .

INSTALLATION (Wiring)
Polarity of leads is critical to avoid damage to the unit or
system. Check batteries and battery cables for correct polarity and
voltage.
Observe all National and Local Electric Codes when
connecting AC Power Connections.
Mounting location is critical to performance and life span of the
inverter. Heat and Moisture are the two worst enemies of any
electronic device. Therefore, when choosing a mounting location,
consider the following requirements listed in order of importance:
Inverter must be sheltered from the elements. Select a clean, dry
location.
Inverter requires adequate ventilation for cooling. With proper
cooling, the inverter will operate efficiently and meet its published
ratings. All models can be mounted in several positions. Best
position, with fan down. Second best, horizontal. Third, vertical
with fan up. Least preferred, upside down.
Inverter should be mounted as close to the battery as possible.
Shorter wire has less resistance, which translates to increased
efficiencies.
An in line fuse is recommended, to protect the battery and wiring to
the inverter. This fuse should be located very close to the battery
positive (+) terminal. To select appropriate size fuse, consult the
"Rated and Peak Current" table in appendix "B".

ADDENDUM FOR X20, X27, & X28 OPTIONS (XP600 AND XP1100)
GENERAL
The X20, X27, and X28 option provides for an alarm contact OR an AC transfer switch on
EXELTECH XP Series inverters. The alarm relay monitors the inverter’s AC output and
will energize the alarm contact when the inverter fails to produce AC.
The AC transfer switch can be configured in two ways (via jumpers)
1. Inverter as the primary source of AC power.
2. Utility as primary source of AC power.
CAUTION: “ ANY OPTION THAT USES TRANSFER SWITCH IS NOT
AUTHORIZED FOR USE IN LAND MOBILE APPLICATIONS ”
NOTE: All secondary AC power sources other than the inverter will be referred to as
utility. A secondary source of AC power includes utility, “shore power”, generator, etc.
When the primary source of AC power fails, the transfer switch “switches” to its
secondary source of AC power in 50ms or less. When the primary source of power is
present again (turns back on), the transfer switch “switches” back to the primary source
of power in 50ms or less.

connections to the inverter BEFORE connecting DC power to the battery.

Page 15 of 17
ALARM CONTACT CONFIGURATION
-X27 OPTION
The alarm contact is configured via jumpers on a removable terminal plug on the back
of the inverter
1. Remove the terminal plug from the inverter by hand or with needle-nose pliers. On
the underside of the plug are screw terminals to set connections. (The terminal plug
can take up to 12GA wire.)
2. Insert a jumper between COIL and INV. (see drawing) When the inverter is on, the
alarm relay will energize.
If it is desired to sense the AC voltage elsewhere in the system such as after a circuit
breaker, remove the jumper between COIL and INV and connect the AC hot from the
point you want to sense to the COIL contact.
3. Connect alarm signal input wire (supplied by operator) to “C” (common) contact.
Connect alarm signal output wire to either NO (normally open) or NC (normally close)
contacts.
OPERATION
When Battery voltage is available to the inverter, the inverter will turn “on” when the
front panel switch is turned “on” OR when the RMT (remote) terminal is connected to
battery negative. When the inverter comes “on” the alarm relay will energize and there
will be continuity between the NC (normally open) and “C” (common) contacts of the
relay terminals.
Inverter AC output will be available from the NEMA 15 terminals in the front (plug) and
at the output terminals in the rear of the inverter (terminals marked INVOUT for AC hot,
NEUTRAL for AC return, and CHASSIS for ground). To shut “off” the inverter the front
switch must be turned “off” AND the remote switch must be in the “off” position.
