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

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.

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.

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.
