Using the Inverter.
The inverter is capable of continuously powering most 220-240v AC products within the inverters rated
continuous output power or less. Its AC output waveform is a pure sine wave.
When many AC products are first switched on, they initially consume more power than their power
rating. For a loading such as a motor, there will be surge current when starting. Please note the starting
current can’t exceed the maximum rated current of the inverter. The starting current of motor may be
7-12 times the rated current.
CAUTION. The inverter can be damaged if the rated current exceds the Inverters maximum
rating and this not be covered by warranty.
Voltage Drops under Load.
It is normal that the Input and output voltage will drop when a heavy load is present. You must take
action in case below conditions.
• When the battery DC voltage is reduced below 11.5/21/42 volts the solution is to increase the battery
capacity or reduce the load on inverter.
• When output AC voltage drops below acceptable levels the solution is to increase the battery capacity
or reduce the load on inverter.
Surge Power Overload.
Although the inverter can supply momentary surge power, occasionally some products rated less than
the rated continuous output power may exceed its surge capabilities and trigger its safety overload shut
down feature. If this problem occurs when attempting to operate several AC products at the same time,
try first by switching on the inverter with all AC products switched off then one by one switch each on,
starting with the high surge product first.
Indicators and Controls.
The AC outlets are provided on one end of the inverter any combination of 220-240v AC products with a
total continuous power consumption of the inverters rating or less may be plugged in.
• The ON/OFF switch enables output of AC power at the Outlets.
• The GREEN POWER light indicates AC power is present at the AC outlets and the inverter is operating
normally.
• The RED FAULT light indicates inverter shutdown caused by low or high voltage, overload or excessive
temperature.
• When the inverter senses that the voltage at its DC input has dropped to 10.9-11.5V an audible alarm
sounds, this will allow time for computers or other sensitive devices to be shut down. After auto shut
down the RED FAULT light illuminates.
• If an AC product rated higher than the rated continuous power or draws excessive surge power
when connected the inverter will shut down and the RED FAULT light will turn on.
• If the inverter exceeds a safe operating temperature due to insufficient ventilation or a high a
temperature environment it will automatically shut down the RED FAULT light will turn on and the
audio warning will sound.
• Should a defective battery charging system cause the battery voltage to rise to a dangerously high
level, the inverter will automatically shut down.
