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 exceeding the range of the input voltage of the inverter

will cause over voltage or under voltage protection.

Also, the battery must supply sufficient current. A small capacity battery

cannot drive a large power electrical appliance. In this case, the battery will

cause an 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 a lead

acid battery is 12VDC, and load power is 1000W, therefore, the actual

current of the battery is about 1000W÷12V×110%≈ 91.6Adc.

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

discharge time is 2000Ah

(1000

Notice: The result of the formula above is on the basis of discharging rate of 20 hours

of the battery, that is, the result is from the discharging current of 2000Ah battery not

to exceed 100A. When the charging current exceeds this value, the discharging period

will be reduced. And the capacity of the battery may also influence the result. See the

specification of the battery manufacturer for more detailed information.

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 ground. The ground

terminal has already been connected to the ground wire of the AC output receptacle

through the inverter.

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

≈

110%)

21.8 hours

The chassis of the vehicle. In a boat, connect it to the boat's grounding system. In a

fixed location, connect the ground terminal to earth.

Warnings:

● Make sure to tighten all connections. The ground wire must be 14AWG (2.08 mm )

or even larger.

● Do not operate the power inverter without connecting to ground. Electric shock may

result.

2) Connect to the lead acid battery or other type within dc input range

(1) Please check all the safety precautions before connecting, and then check whether

the battery voltage is in accordance with the input voltage of the inverter. Battery and

inverter voltages must match

(2) The connecting wire must bear enough current. These inverters require 1 AWT or

larger wire for its battery connections.

Notice:

(1) In practice, thicker wire can be replaced by two thin parallel wires if the total cross-

sectional area of the wire meets the requirements. This may however cause an

increase in RF.

(2) In high current, the input DC wire may produce a 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 the inverter and then connect the anode wire of the battery to the anode

terminal (red) on the inverter, and tighten them.

Warnings:

(1) Please wear eye protection and work clothes when working around the battery to

protect your eyes and skin from acid and corrosive objects.

(2) In case acid makes contact with your skin, clean it using soap and water as soon

as possible. If the acid splashes into your eyes accidentally, rinse with cold water

and go to a hospital.

(3) Do not put any combustible materials in the location of installation for it will result in

a fire hazard.

(4) Keep good ventilation. The battery may produce a little flammable gas when used,

so keep away from the inverter and it is better to install them in a different space.

(5) Tighten all DC connections, or it will result in over- reduction of the voltage or over-

temperature of the inverter.
