Inverter related preventing paralleling of the ac output. The ac output of this inverter cannot be synchonised with another ac source and hence, it is notsuitable for paralleling. The ac output of the inverter should never be connected directly to an electrical breaker panel / load center which is a...

Inverters - general information page 4 why an inverter is needed the utiliti grid supplies you with alternating current (ac) electricity. Ac is the standard form of electricity for anything that “plugs in” to the utility power. Direct current (dc) electricity flows in a single direction. Batteries p...

Loads that require “surge power” to start resistive types of loads (like incandescent lamps, toaster, coffee maker, electric range, iron etc) do not require extra power to start. Their starting power is the same as their running power. Some loads like induction motors and high inertia motor driven d...

Power rating of microwaves the power rating of the microwave generally refers to the cooking power. The electrical power consumed by the microwave will beapproximately 2 times the cooking power. The “surge power” of the inverter should be 2 times the electrical power (i.E., 4 times the cooking power...

Voltage, current, power factor, types of loads the voltage wave form of 230vac, 50 hz mains / utility power is like a sinewave. In a voltage with a sinewave-form, the instantaneous value and polarity of the voltage varies with respect to time and the wave-form is lijke a sine wave. In one cycle, it ...

The output voltage of a sine-wave inverter has a sine wave-form like the sine wave-form of the mains / utility voltage. In a sine wave, the voltage rises and falls smoothly with a smoothly changing phase angle and also changes its polarity instantly when it crosses 0 volts. In a modified sine wave, ...

Caution: please note that the ac output connections and the dc input connections on these inverters are not conected (bonded) to the metal chassis of the inverter. Both the input and output connections are isolated from the metal chassis and from each other system groundin g, as required by national...

Grounding to earth or to other designated ground. For safety, the metal chassis of the inverter is required to be grounded to the earth ground or to the other designated ground (for example, in a mobile rv, the metal frame of the rv is normally designated as the negative dc ground). An equipment gro...

Powering direct / embedded switched mode power supply (smps) non-linear nature of current drawn by switched mode power supplies. Power supplies are used to convert ac voltages like 230 vac to various dc voltages like 3.3 v, 5 v, 12 v, 24 v, 48 v etc. Majority of modern day electronic devises use emb...

The inverter converts the dc voltage of the battery to 230v, 50 hz. Ac voltage. The voltage conversion takes place in two stages. In the first stage, the dc voltage of the battery is converted to a high voltage dc using high frequency switching and pulse width modulation (pwm) technique. In the seco...

The inverter will require deep cycle lead acid batteries of appropriate capacity. Lead-acid batteries can be categorized by the type of application: automotive service- starting / lighting / ignition (sli, a.K.A. Cranking) and deep cycle service. Sli batteries everybody is familiar with the sli batt...

Depth of discharge and battery life the more deeply a battery is discharged on each cycle, the shorter the battery life. Using more batteries than the minimum required will result in longer life for the battery bank. A typical cycle life chart is given at table 2 below: table 2. - typical cycle life...

Sizing the inverter battery bank. One of the most frequently asked question is, “how long will the batteries last? This question cannot be answered without knowing the size of the battery system and the load on the inverter. Usually this question is turned around to ask ”how long do you want your lo...

Dc side connections the dc input power to the inverter is derived from deep cycle batteries of the required capacity. Read under “specifying batteries, chargers and alternators” on page 14 for details on sizing and charging of batteries. Preventing input over voltage it is to be ensured that the inp...

Connection from the batteries to the dc input side of the inverter – cable and fuse sizes the flow of electric current in a conductor is opposed by the resistance of the conductor. The resistance of the conductor is directly proportional to the length of the conductor and inversely proportional to i...
Page 22
Dc input terminals the dc input terminals have a tubular hole with a set screw. A suitable pin type of copper terminal should, therefore, be used on the cable end. Do not insert the stranded bare end of the cable directly into the tubular hole as the set screw will not pinch all the strands and will...

Ac output connections the inverter uses standard vde european receptacle for connecting the ac output to devices and appliances fitted with a 2-pin schuko plug. In this vde receptacle, two round slots are connected to the current-carrying conductors of the ac power source inside the inverter. The ce...

Page 23 operation powering on the loads after the inverter is switched on, it takes a finite time for it to become ready to deliver full power. Hence, always switch on the load(s) after a few seconds of switching on the inverter. Avoid switching on the inverter with the load already switched on. Thi...

No load draw (idle current) when the on / off switch is turned on, all the circuitry inside the inverter becomes alive and the ac output is made available. In this condition, even when no load is being supplied (or, if a load is connected but has been switched off), the inverter draws a small amount...

Shut-down due to reversal of polarity at the dc input terminals. The positive of the battery should be connected to the positive dc input terminal of the inverter, (the tip of the cigarette lighter plug), and the negative of the battery should be connected to the negative dc input terminal of the in...
