Modified Sine Wave Inverter with AC Auto Switch and Charger

4. Electrical Performance

4.1. Inverter

4.1.1 What is an Inverter?

Power inverter is an electronic device that convert DC(Direct Current) battery power to standard AC(Alternating Current) power. DC is the power that is produced by battery while AC is the standard power needed to run

electrical equipment. A power inverter does the opposite of a rectifier and is

used in places and situations where AC power is not available.

4.1.2 Pure Sine Wave Inverter

If you want to run your equipment exactly to the manufacturer's specifications,

choose a pure sine wave inverter. With pure sine wave, motor loads start easier

and run cooler. Some equipment only operate properly with pure sine wave

inverter, such as laser printers, variable speed motors and digital clocks.

4.1.3 Modified Sine Wave Inverter

If your equipment can accept some voltage fluctuation , consider a modified sine wave inverter . These inverters provide mobile power at a more affordable

price and come in a full range of size from handheld to high performance . Do

not use to power sensitive devices such as medical equipment or computers .

Some audio equipment may perform poorly if run on Modified Sine Wave power Inverter

4.1.4 Soft Start function our inverter is engineer with Soft Start features , when the inverter is turning

on , the output voltage gradually ramp up from 0VAC to Rated Voltage in about

1 Sec, this effectively reduce high starting inrush current drawn by AC loads

such as switched mode power supplies and inductive loads .

Do not parallel the AC output of the inverters to increase CAUTION:power capacity as they have no stacking functionality.

4.2 AC Charger(Option)

4.2.1 3-Step ChargingA) Bulk Charge Stage: Current is supplied to the battery at a constant rate while

voltage gradually rises.

B) Absorption Charge: Voltage remains constant and current reduces as the

battery becomes charged. This ensures complete charging.

C) Floating Stage: After the battery reach full charge, charging voltage is

reduced to a lower level to prevent gassing and to prolong life. This stage is

often referred to as a maintenance charge. Rather than charging a battery, it

keeps an already-charged battery from discharging while providing load current.

Absorb Charging: 14.6 Vdc(12V version)/

29.2Vdc(24V version)

Float Charging: 13.8Vdc(12V version)/

27.6Vdc(24V version)

*Charging voltages can be customized

in factory.

4.3 UPS Mode and ECO mode

4.3.1 UPS Mode : the AC input of the inver ter is cont inual ly moni tored.

Whenever AC power falls ,the inverter automatically transfers back to

the inverter mode with minimum power interruption to your appliances-

as long as the inverter is turned on. The transfer time is usually fast enough

to keep your equipment (including computers) powered up. The time will

be less than 16 milliseconds .4.3.2 ECO Mode : Battery voltage is lower than alarm point , the inverter

automatically transfers back to the AC utility to the loads, the transfer

time also very fast enough to keep your equipment(including computers)

powered up . The time will be less than 16 milliseconds. After low battery

voltage shut off, the inverter is able to restore to work after the battery

voltage recovers to 13V/26V/52V(With power switch still in “ON” Position).

Working temperature: -5℃ to 40℃ Storage temperature: -5℃ to 70℃ Relative Humidity: 0% to 95%_non-condensing

Cooling: Forced air

7.2 DC WireThough your Inverter is a high-efficiency converter of electricity, its rated

output capacity is limited by the length and gauge of the cabling running from

the battery to the unit. Use the shortest length and largest diameter cabling to

fit your Inverter's DC Input terminals. Shorter and heavier gauge cabling

reduces DC voltage drop and allows for maximum transfer of current. Your

Inverters is capable of delivering peak wattage at up to 200% of its rated

continuous wattage output for brief periods of time. Heavier gauge cabling

should be used when continuously operating heavy draw equipment under

these conditions. Tighten your Inverters and battery terminals to approximately

0.8 Meter to create an efficient connection and to prevent excessive heating at

this connection. Insufficient tightening of the terminals could void your

warranty.

7.3 AC Wire when in bypass mode the AC input power will supply both the loads and
