MAXX
SST
™
3000 Safety Features
Built-in Safety Features include:
• Automatic overload (over-temperature) shutdown and reset (activated if AC output
exceeds 6000 watts for more than 3 seconds)
• Automatic AC short-circuit shutdown and reset
• Automatic low voltage audible alarm and reset (sounds at 10.6 volts input)
• Automatic low-voltage shutdown and reset (activates at 10.0 volts DC)
• Automatic high-input voltage shutdown and reset (activates at above
15 volts DC)
WARNING
The
MAXX
SST
™
3000
output should be treated with the same caution as any
110 volt AC circuit. It is very important that anyone who is installing or using the
inverter read and follow all instructions provided in this manual to ensure optimum
safety and performance.
When you use the high output direct wiring feature with the required user-supplied
dual ganged 25 amp circuit breaker, the
MAXX
SST
™
3000
can be installed with
an automatic transfer switch or manual transfer switch. Then, when utility power (or
generator-supplied power) is lost, the inverter will supply the necessary power to
the appliance circuits.
The
MAXX
SST
™
3000
is ideal for powering:
• TV/VCR combinations
• Refrigerator/freezers
• Lights
• Radio receivers/transceivers
• Heavy duty power tools & chargers
• Stereo systems
• Microwave ovens
• Household appliances
• Computers and peripheral equipment
• Dry and/or wet/dry vacuums
• Sump pumps, motors, and other electric-powered equipment
• Air compressors
• Many more appliances, products and devices
The
MAXX
SST
™
3000
uses a 12 VDC power source like those found in 12 VDC
motor vehicles or boats or it can be operated using multiple battery configurations
with commercial battery chargers or solar battery chargers. For most heavy-duty
applications, a multiple battery configuration and the use of deep-cycle batteries
is a requirement.

Figure 9. Connections to the High Output Terminal Block.

All wire cable used to make a connection to the High Output Terminal Block should
be insulated and rated at #10 AWG to carry 30 amps. These common cables are
normally color coded Black for the “hot” wire; White for the “neutral” wire and
bare Copper or Green for the ground wire. If this wiring is to be permanently used
in fixed locations, ordinary single conductor wire cable is acceptable. If the cable
will be used in a mobile environment, multi-stranded wire should be used.
Multi-stranded wire can withstand constant cable flexing, while single conductor
(one strand wire) cable cannot. When making connections to the High Output
Terminal Block, follow the wiring configurations shown in FIGURE 9 That is: black
to black, white to white and bare or green to ground. Note that the designation of
the terminals on the inverter are labeled L, N, and ground symbol. “L” stands for
“load”, the “hot” terminal. "N" stands for "Neutral". The breaker should be mount-
ed in a metal box for that breaker type. When you purchase a breaker and box,
ensure that they are intended for use together. Locate the 110 VAC breaker box
near the inverter terminals to ensure access to the breaker if it trips.
If the High Output Terminal block wiring is used with existing wiring, ensure that the
AC from the inverter is protected with a dual ganged 30 amp circuit breaker and
is isolated from other sources of AC by using a transfer switch that simultaneously
switches Neutral and Hot output. Refer to
FIGURE 4
as a guide to wiring to a
transfer switch.
