DC POWER SOURCE REQUIREMENTS
The DC power source must provide >11.0 ± 0.3V and < 15.3 ± 0.3V DC and must be able to supply the
necessary current to operate the load. The power source may be a battery or a well-regulated DC power
supply. To obtain a rough estimate of the current (in Amperes) the power source must deliver, simply
divide the power consumption of the load (in Watts AC) by 10.
Example: if a load is rated at 100 Watts AC, the DC power source must be able to deliver: 100 / 10 = 10A.
The inverter will provide you nominal 115 VAC when powered by a 12 VDC source such as is found in
a vehicle or multiple battery configurations as shown in fig. 2. This manual does not describe all of
the possible types of battery configurations, battery charging configurations and battery isolation
configurations.
for normal operation of the inverter, the DC power source must provide >11.0 ± 0.3V and < 15.3 ± 0.3V
and the required current. This DC power source must be a well-regulated DC power supply or alternator
and deep cycle battery system typically found in vehicles and marine crafts. The DC power source may
also be two or more 12 volt batteries connected in parallel. on larger applications, the power source may
be several batteries connected in parallel as shown in fig. 2.

INSTALLATION NOTES
WARNING: Ensure ventilation when using batteries. Batteries may generate flammable
gas during charging or discharging.
The inverter (350 W to 2000 W models) has four slots in its mounting bracket that allow the unit to be
fastened against a bulkhead, floor, wall or other flat surface. Ideally, the mounting surface should be
cool to the touch.
It is more electrically efficient to use longer AC wiring than DC wiring, so install the inverter as close as
possible to the 12 VDC power source.
