Warnings:
●
To make sure the firmness of the connection. The ground wire must be 14AWG (2.08
2
mm ) or even larger.
●
Do not operate the power inverter without connecting to the ground. Electric shock may
result.
2) Connect to the lead acid battery
(1) Please do all the safety precautions before connection, and then check whether the
battery voltage is in accordance with the input voltage of the inverter. Only the voltage of
the battery accords with the requirements can be allowed to connect with the inverter.
(2) The connecting wire must bear enough current. Depending on the table below, please
choose the input DC wire or larger one.

5. BATTERY
1). Voltage and current of the battery
The battery is designed to supply the unit with DC input voltage and the rated voltage
should be in accordance with the rated input voltage of the inverter. Any voltage exceeds
the range of the input voltage of the inverter will cause over voltage or under voltage
protection.
In the meantime, the battery should supply sufficient current. The small capacity battery
cannot drive the large power electrical appliance. In this case, the battery will be in under
voltage protection because of the over-discharge of the battery. The simple calculation
method of battery current is: load power divided by battery voltage. Due to the
consumption of the inverter itself, the actual current will be about 10% larger. For example,
the voltage of lead acid battery is 12VDC, and load power is 1000W, therefore, the actual
current of the battery is about
1000W÷12V×110%≈91.6A.
2). Battery operating time
Battery operating time depends on battery capacity and current, and the calculation
formula of operating time is: battery capacity divided by current, that is, battery capacity
divided by the value of the load power divided by battery voltage times 110%. For example,
battery specification is 12V, 2000Ah, load power is 1000W, so the total discharging time is
2000Ah÷ (1000÷12×110%) ≈21.8 hours
Notice:
The result of formula above is on the basic of discharging rate of 20 hours of the
battery, that is, the result is from the discharging current of 2000Ah battery not exceed
100A. When the charging current exceeds this value, the discharging period will reduce.
And the quantity of the electricity of the battery may also influence the result. See the
specification of the battery manufacturer.
6. Connection
1) Grounding
The power inverter has a terminal on the rear panel marked " Grounding "or " ". This is
used to connect the chassis of the power inverter to the ground. The ground terminal has
already connected to the ground wire of AC output receptacle through the internal
connecting wire.
The ground terminal must be connected to the ground wire, which will vary depending on
where the power inverter is installed. In a vehicle, connect the ground terminal to the
chassis of the vehicle. In a boat, connect it to the boat's grounding systems. In a fixed
location, connect the ground terminal to earth.
Notice:
(1) The table above is only for your reference. In practice, the thick wire can be replaced
by two thin parallel wires if only the total cross-sectional area of the wire meets the
requirements.
(2) In high current, the input DC wire may produce voltage drop, therefore, the operating
voltage should be subject to the value on the terminals. If the voltage drop is too large,
you can increase the cross-sectional area or reduce the length of the lead.
(3) Connect cathode wire of the battery to the cathode terminal (black) on the rear panel of
inverter and then connect the anode wire of the battery to the anode terminal (red) on
the inverter, and fix them.
Warnings:
1) Please wear eye patch and work clothes when working around the battery to avoid the
acid and corrosive objects harm your eyes and skin.
