Figure 6 – Battery
Operating Time
For example, as shown in FIGURE 6, using a 400 amp hour battery (batteries),
if the average power usage will be 1000 watts, the operating time will be
about 150 minutes. A larger capacity battery will deliver more operating time
between recharges.
NOTE: The manufacturer recommends conservative estimates when selecting a
battery. More amp hours will deliver a reserve capacity, and a larger
capacity battery will not be subject to deep discharges. Ideally, the
number of amp hours (AH) you expect to use should be less than 50%
of the battery’s rated capacity.
4.4 PROTECTIVE FEATURES
LOW BATTERY ALARM:
An audible alarm will sound when:
1. The 12 VDC power supply voltage drops down to 10.6 volts. This indicates that
the battery needs to be charged or there is an excessive voltage
drop between the battery power source and the inverter.
NOTE: It is normal for the alarm to sound when the inverter is being connected
to, or disconnected from, a 12VDC-power source. This does NOT
indicate a problem. However, if this alarm sounds continuously, discon-
tinue inverter operation and charge the battery before resuming operation.
If the voltage drops to 10.0VDC, the inverter will automatically shut
down.
If the low voltage alarm sounds when the battery is fully-charged, refer to the
troubleshooting table for possible causes and remedies. (Pages 19-20)
CIRCUIT PROTECTION: The inverter has electronic circuit protection against
overload or short circuit conditions.

WARNING: If turning the front panel mounted switch OFF then
ON does not reset the inverter, DO NOT ATTEMPT TO OPEN THE
INVERTER. Opening the inverter, for any reason, will void the war-
ranty. The unit must be returned to Vector Manufacturing, Ltd. for test-
ing and repair by professional factory technicians.
