OPERATING LIMITS
INPUT VOLTAGE/AUTO SHUTDOWN
On/Off Switch
The ON/OFF switch turns the
control circuit in the inverter
on and off. It DOES NOT
disconnect power from the
inverter.
When the switch is in the OFF
position, the inverter draws
no current from the battery.
When it is the in ON position,
but no power is being
supplied to the load, the
inverter draws less than
500 milliamperes from the
battery. This is low current
draw. It would take more
than a week to discharge a
100 ampere-hour battery at
this draw rate.
You don’t have to worry about
excessive drain on a battery if
you leave the inverter
switched on for a few days.
However, you should switch it
off if you are not planning to
recharge the battery within
about a week.
Fault Indicator
The "fault" indicator of your
CPI 150 will light whenever
the unit detects excessively
high or low input voltage, or
begins to overheat.

Power Output
Your CPI 150 will deliver
150 watts continuously. It
can deliver 180 watts for
about 30 minutes, after
which it must cool for
about 15 minutes before
it can resume operation at
150 watts. (NOTE: the
wattage rating applies to
resistive loads.)
Input Voltage
Your CPI 150 will operate
from input voltage ranging
from 10 to 15 volts.
Optimum performance occurs
when the voltage is between
12 and 14 volts.
If the voltage drops below
10.7 ± 0.3 volts, an audible
low battery alarm will sound.
The inverter will
automatically shut down if
the input voltage drops below
10.0 ± 0.3 volts. This
protects the battery from
being over-discharged. The
inverter will restart when the
input voltage exceeds 12.0 ±
0.5 volts.
The inverter will also shut
down if the input voltage
increases to 15.0 ± 0.5 volts.
This helps protect the unit
from damage due to excessive
input voltage. Although the
inverter is protected in this
way, it may still be damaged
should the input voltage
exceed 16 volts.
Automatic Shutdown
The unit will automatically go
into thermal shutdown if it
becomes overheated due to
excessive input voltage, poor
circulation or high ambient
temperature.
