Overload Protection: When the load is over the rated power, the buzzer will sound after 3 to 5
seconds, and the green LED light will flash quickly. The power inverter will cut off automatically
to protect the inverter.
Short-circuit Protection: When the load is more than 2 times the rated power or the unit is in short
circuit, the buzzer will sound after 1-2 seconds and the green LED light will flash quickly. The
power inverter with the battery charge will cut off power automatically to protect the unit.
Temperature Protection: When the item is working and the temperature is over 60C – 70C, the
buzzer will sound immediately and the green LED light will flash quickly. The power inverter
charge will cut off output to protect your unit.
AC input low voltage Protection: When the AC input voltage is lower than 150V, the inverter will
cut off AC output automatically, at the same time it will stop charging the storage battery. The
yellow indicator will be off, and if the power switch on the item is on at this time, it can convert the
output automatically, so it will be convenient and supply a steady stable voltage still.
AC input over voltage protection: When the AC input voltage is higher than 250V, the inverter will
cut off AC output automatically, at the same time it will stop charging the storage battery. The
yellow indicator will be off, and if the power switch on the item is on at this time, it can convert the
output automatically, so it will be convenient and supply a steady stable voltage still.
ATTENTION: If the low voltage protection, over voltage protection, overload protection, short-
circuit protection or temperature protection actions occur, the unit will need to be restarted. This
allows the protective measures to be reset so that they can continue to protect your equipment.
CHOOSING A POWER CONVERTER
All electronic products should have their rated power indicated on their labels. The rated power
should be less than the rated power of the power converter.
The method of how to estimate the power(W): the total of the load power should be equal to the
rated power(W) of the power inverter.
For example, you use two computers (250Wx2), a light bulb (60W), a TV (200W), a fan (180W) all
at the same time.
Their total power is 250W + 250W + 60W + 200W + 180W = 940W. You will therefore need a
power inverter with a rated power of 1000W with battery charge.
CHOOSING A STORAGE BATTERY
You must choose a storage battery that accord with DC input voltage that can supply enough
working current (not less than the full load input DC current of the power inverter with battery
charge). For a power inverter with battery charge of 12V-220V-2000W, you should choose a
storage battery that's more than 200AH.
