Owner`s manual

To get an estimate of the current (in amps) that the battery must be capable of
delivering, divide the load consumption power (in watts) by (10).
Keep in mind that most appliances are not operating for long periods of time. For
example, a typical home-use coffee maker draws 500 watts during its brew time of 5
minutes, but it maintains the temperature of the pot at about 100 watts. Typical use
of a microwave is only for a few minutes, sometimes at low power. Some exceptions
to brief operating times are lamps, TVs and computers.
In most instances, the inverter can be left connected to the battery when not in use,
make sure power switch is in the OFF position.
Battery performance drop in low environment temperatures. Higher capacity
batteries should be installed if the environment temperature below 20
o
C.
PROTECTIVE FEATURES OF THE INVERTER
OVER TEMPERATURE PROTECTION – If the temperature inside the inverter is
too high, the unit will automatically shut down. Allow the unit to cool for at least 15
minutes before restarting after a heat-related shutdown. Unplug unit while cooling.
LOW BATTERY VOLTAGE PROTECTION - This condition is not harmful to the
inverter but could damage the power source. The inverter automatically shuts
down when input voltage drops to 10.5 volts.
OVER VOLTAGE PROTECTION – The inverter will automatically shut down
when the input voltage exceeds 15.0 volts DC. Input voltage exceeds 16 volts
could damage the inverter.
OVERLOAD PROTECTION – The inverter will automatically shut down when the
continuous draw exceeds rated watts.
SHORT CIRCUIT PROTECTION – The inverter will shut down. Remove the short
circuit and restart inverter.
EARTH FAULT PROTECTION – This inverter comply with the standard current
leakage allowance. When large current leakage to earth terminal occurs, the
protection circuit activated and shut down the inverter, which prevent electric
shock to human. Turn OFF the inverter, unplug the fault AC appliance and then
turn ON is the only way to restart it.
LOW BATTERY ALARM – An alarm will sound when the voltage from the battery
drops to 10.6 volts. This is an indication that the battery needs to be recharged.
The user should stop operation of the electronic device at this time since the
inverter will shut down automatically shortly thereafter, when the battery voltage
drops to 10 volts. Start your engine to recharge the battery.
