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.
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.

When the inverter is in work condition, the input voltage and output power will be
shown on the digital display screen by turns. Likewise, when the inverter goes into
protection, corresponding letters will be also shown on the screen. Different letters
mean the inverter is in different protection conditions.
1. When the input (V) LED is on, the current input voltage is shown.
2. When the output (KW) LED is on, the current output power (KW) is shown.
3. When the output (W) LED is on, the current output power (W) is shown.
4. LO means the inverter is in under voltage protection.
5. HI means the inverter is in over voltage protection.
6. OL means the inverter is in overload protection or short-circuits protection.
7. OH means the inverter is in OVER HEAT protection.
8. ABOUT SOFT START TECHNOLOGY
The output voltage rises up from low to normal when the inverter is turned on. This can
reduce attack of high startup currents, which can make startup easier of large inductive
loads.
As for the large inductive loads, such as electric tools and the capacitive loads,
suggest turning on the switch of the appliance firstly and later the inverter's. The soft
start works.
9. THE OUTPUT WAVE FORM
The output wave form of this inverter is Pure Sine Wave, which is much like the one
from utility-supplied AC electricity, even more purer; pure sine wave is applicable in
most of loads, including electrical equipments, such as Linear Adaptor, switching power
supply, transformer, and motor and so on.
Comparing with Modified wave form, for inductive loads such as refrigerator and electric
fans, pure sine wave form can improve its power factor and the battery's efficiency and
reduce working noises effectively from appliances. For capacitive loads such as adapter
of lap-top, pure sine wave can lower the rush current at work and reduce interferences to
increase reliability and prolong the life of the product.
