seCtIOn 1 | safety Instructions Preventing fire and explosion hazards • Working with the unit may produce arcs or sparks. Thus, the unit should not be used in areas where there are flammable materials or gases requiring ignition protected equipment. These areas may include spaces containing gasoline-powered machinery, fuel tanks, and battery compartments. Precautions when working with batteries • Batteries contain very corrosive diluted sulphuric acid as electrolyte. Precautions should be taken to prevent contact with skin, eyes or clothing. • Batteries generate Hydrogen and oxygen during charging resulting in evolution of explosive gas mixture. Care should be taken to ventilate the battery area and follow the battery manufacturer’s recommendations. • Never smoke or allow a spark or flame near the batteries. - Page 5 seCtIOn 1 | safety Instructions the 12V battery version and 33.0 VDC for the 24V battery version to prevent permanent damage to the unit. Please observe the following precautions: • Ensure that the maximum charging voltage of the external battery charger / alterna- tor / solar charge controller does not exceed 16.5 VDC for the 12V battery version and 33.0 VDC for the 24V battery version • Do not use unregulated solar panels to charge the battery connected to this unit. Under cold ambient temperatures, the output of the solar panel may reach > 22 VDC for 12V Battery System and > 44 VDC for the 24V Battery system.

Page 6: General Information
seCtIOn 2 | General Information The following definitions are used in this manual for explaining various electrical concepts, specifications and operations: Peak Value: It is the maximum value of electrical parameter like voltage / current. RMS (Root Mean Square) Value: It is a statistical average value of a quantity that varies in value with respect to time. for example, a pure sine wave that alternates between peak values of Positive 325V and Negative 325V has an RMS value of 230 VAC. Also, for a pure sine wave, the RMS value = Peak value ÷ 1.414. Voltage (V), Volts: It is denoted by “V” and the unit is “Volts”. It is the electrical force that drives electrical current (I) when connected to a load. It can be DC (Direct Current – flow in one direction only) or AC (Alternating Current – direction of flow changes peri- odically). The AC value shown in the specifications is the RMS (Root Mean Square) value. - Page 7 seCtIOn 2 | General Information the net effect is a tendency to cancel each other. Hence, in a circuit containing both inductances and capacitances, the net Reactance (X) will be equal to the difference be- tween the values of the inductive and capacitive reactances. The net Reactance (X) will be inductive if X > X and capacitive if X > X impedance, Z: It is the vectorial sum of resistance and reactance vectors in a circuit.

Reactive Load: A device or appliance that consists of a combination of resistive, induc- tive and capacitive elements (like motor driven tools, refrigeration compressors, micro- waves, computers, audio/ video etc.). These devices require Apparent Power (VA) from the inverter to operate. The Apparent Power is a vectorial sum of Active Power (Watts) and Reactive Power (VAR).

- Page 9 seCtIOn 2 | General Information frequency harmonic content in a modified sine wave produces enhanced radio interfer- ence, higher heating effect in inductive loads like microwaves and motor driven devices like hand tools, refrigeration / air-conditioning compressors, pumps etc. The higher frequency harmonics also produce overloading effect in low frequency capacitors due to lowering of their capacitive reactance by the higher harmonic frequencies. These capaci- tors are used in ballasts for fluorescent lighting for Power factor improvement and in single-phase induction motors as start and run capacitors. Thus, modified and square wave inverters may shut down due to overload when powering these devices.
- Page 10 seCtIOn 2 | General Information Power Rating of the inverters The continuous output power rating of the inverter is specified in Active Power in Watts for resistive types of loads like heating elements, incandescent lamps etc. where Power factor (Pf) = 1. The Surge Power rating is for < 1 sec. Non resistive / reactive loads with Power factor < 1 like motors (Pf = 0.4 to 0.8), non Power factor corrected electronics (Pf = 0.5 to 0.6) etc, will draw higher Apparent Power in Volt Amps (VA). This Apparent Power is the sum of Active Power in Watts plus Reac- tive Power in VAR and is = Active Power in Watts ÷ Power factor. Thus, for such reactive loads, higher sized inverter is required based on the Apparent Power. further, all reac- tive types of loads require higher inrush / starting surge power that may last for > 1 to 5 sec and subsequent lower running power. If the inverter is not sized adequately based on the type of AC load, it is likely to shut down or fail prematurely due to repeated overloading. inFo The manufacturers’ specification for power rating of the appliances and devices indicates only the running power required.

Page 12: Powering Direct / Embedded Switch Mode Power Supplies (Smps)
seCtIOn 4 | Powering Direct / embedded switch Mode Power supplies (sMPs) Switch Mode Power Supplies (SMPS) are extensively used to convert the incoming AC power into various voltages like 3.3V, 5V, 12V, 24V etc. that are used to power various devices and circuits used in electronic equipment like battery chargers, computers, audio and video devices, radios etc. These power supplies use large capacitors in their input section for filtration. When the power supply is first turned on, there is a very large inrush current drawn by the power supply as the input capacitors are charged (The ca- pacitors act almost like a short circuit at the instant the power is turned on). The inrush current at turn-on is several to tens of times larger than the rated rMS input current and lasts for a few milliseconds. An example of the input voltage versus input current waveforms is given in fig. -

seCtIOn 5 | Principle of Operation These inverters convert DC battery voltage to AC voltage with an RMS (Root Mean Square) value of 230 VAC, 50 Hz RMS. The waveform of the AC voltage is a pure sine wave form that is same as the waveform of grid power (Supplementary information on pure sine waveform and its advantages are discussed on pages 8 & 9). fig. 5.1 below specifies the characteristics of 230 VAC, 50 Hz pure sine waveform. The instantaneous value and polarity of the voltage varies cyclically with respect to time. for example, in one cycle in a 230 VAC, 50 Hz system, it slowly rises in the positive direction from 0V to a peak positive value “Vpeak” = + 325V, slowly drops to 0V, changes the polarity to negative direction and slowly increases in the negative direction to a peak... -

The Capacity “C” in Ah relates to the ability of the battery to provide a constant specified value of discharge current (also called “C-Rate”) over a specified time in hours before the battery reaches a specified discharged terminal voltage (Also called “End Point Voltage”) at a specified temperature of the electrolyte. As a bench- mark, the automotive battery industry rates batteries at a “Discharge Rate” C/20 Amperes corresponding to 20 Hour discharge period. The rated capacity “C” in Ah in this case will be the number of Amperes of current the battery can deliver for 20 Hours at 80ºf (26.7ºC) till the voltage drops to 1.75V / Cell i.e. 10.5V for 12V battery, 21V for 24V battery and 42V for a 48V battery. for example, a 100 Ah battery will deliver 5A for 20 Hours. Rated capacity in Reserve capacity (Rc) Battery capacity may also be expressed as Reserve Capacity (RC) in minutes typically for automotive SLI (Starting, Lighting and Ignition) batteries. It is the time in minutes a vehicle can be driven after the charging system fails. - Page 18 seCtIOn 7 | General Information on Batteries for Powering Inverters as the “C-Rate”. If the battery delivers a very high discharge current, the battery will be discharged to the “End Point Voltage” in a shorter period of time. on the other hand, if the battery delivers a lower discharge current, the battery will be discharged to the “End Point Voltage” after a longer period of time. Mathematically: eQUAtion 1: Discharge current “C-Rate” = Capacity “C” in Ah ÷ Discharge Time “T” Table 7.2 below gives some examples of C-Rate specifications and applications: tABLe 7.2: DiScHARGe cURRent RAteS - “c-RAteS” Hours of discharge time C-Rate Discharge Current in Amps Example of C-Rate “T” till the “End Point Discharge Currents for fraction Decimal...

- Page 20 seCtIOn 7 | General Information on Batteries for Powering Inverters Table 7.3 (page 19) will show that a 100 Ah capacity battery will deliver 100% (i.e. full 100 Ah) capacity if it is slowly discharged over 20 hours at the rate of 5 Amperes (50W output for a 12V inverter and 100W output for a 24V inverter). However, if it is dis- charged at a rate of 50 Amperes (500W output for a 12V inverter and 1000W output for a 24V inverter) then theoretically, it should provide 100 AH ÷ 50 = 2 hours. However, the Table above shows that for 2 hours discharge rate, the capacity is reduced to 50% i.e. 50 Ah. Therefore, at 50 Ampere discharge rate (500W output for a 12V inverter and 1000W output for a 24V inverter) the battery will actually last for 50 Ah ÷ 50 Amperes = 1 Hour. State of charge (Soc) of a Battery – Based on “Standing Voltage” The “Standing Voltage” of a battery under open circuit conditions (no load connected to it) can approximately indicate the State of Charge (SoC) of the battery. The “Standing Voltage” is measured after disconnecting any charging device(s) and the battery load(s) and letting the battery “stand”...

Inverters are normally provided with a buzzer alarm to warn that the loaded battery has been deeply discharged to around 80% of the rated capacity. Normally, the buzzer alarm is triggered when the voltage at the DC input terminals of the inverter has dropped to around 10.7V for a 12V battery or 21.4V for 24V battery at C-Rate dis- charge current of C/5 Amps and electrolyte temp.
- Page 22 seCtIOn 7 | General Information on Batteries for Powering Inverters In the example given above, the 10.7V Low Battery / DC Input Alarm would trigger at around 80% discharged state (20% SoC) when the C-Rate discharge current is C/5 Amps. However, for lower C-Rate discharge current of C/10 Amps and lower, the battery will be almost completely discharged when the alarm is sounded. Hence, if the C-Rate discharge current is lower than C/5 Amps, the battery may have completely discharged by the time the Low DC Input Alarm is sounded. Low Dc input Voltage Shut-down in inverters: As explained above, at around 80% State of Discharge of the battery at C-Rate discharge current of around C/5 Amps, the Low DC Input Voltage Alarm is sounded at around 10.7V for a 12V battery (at around 21.4V for 24V battery) to warn the user to disconnect the battery to prevent further draining of the battery. If the load is not disconnected at this stage, the batteries will be drained further to a lower voltage and to a completely discharged condition that is harmful for the battery and for the inverter.

- Page 26 seCtIOn 7 | General Information on Batteries for Powering Inverters The first step is to estimate the total AC watts (W) of load(s) and for how long the load(s) will operate in hours (H). The AC watts are normally indicated in the electrical nameplate for each appliance or equipment. In case AC watts (W) are not indicated, formula 1 given above may be used to calculate the AC watts by multiplying 120 VAC / 230 VAC by the AC current in Amperes. The next step is to estimate the DC current in Amperes (A) from the AC watts as per formula 2 above. An example of this calculation for a 12V inverter is given below: Let us say that the total Ac Watts delivered by the 12V inverter = 1000W. Then, using formula 2 above, the DC current to be delivered by the 12V batteries = 1000W ÷10 = 100 Amperes. next, the energy required by the load in Ampere Hours (Ah) is determined.

- Page 32 seCtIOn 8 | Installation The size (thickness / cross-section) of the conductors is designated by AWG (American Wire Gauge). Please note that a smaller AWG # denotes a thicker size of the conductor up to AWG #1. Wires thicker than AWG #1 are designated AWG 1/0, AWG 2/0, AWG 3/0 and so on. In this case, increasing AWG # denotes thicker wire. The DC input circuit is required to handle very large DC currents and hence, the size of the wires and connectors should be selected to ensure minimum voltage drop between the battery and the inverter. Thinner wires and loose connections will result in poor inverter performance and will produce abnormal heating leading to risk of insulation melt down and fire. Normally, the thickness of the wire should be such that the voltage drop due to the current & the resistance of the length of the wire should be less than 2%. Use oil resistant, multi- stranded copper wire wires rated at 90ºC minimum. Do not use aluminum wire as it has higher resistance per unit length.

seCtIOn 9 | Operation Powering on the Loads After the inverter is switched on, it takes a finite time 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. This may prematurely trigger the overload protection. When a load is switched on, it may require initial higher power surge to start. Hence, if multiple loads are being powered, they should be switched on one by one so that the inverter is not overloaded by the higher starting surge if all the loads are switched on at once.

Also, the inverter can provide continuous power limited to the continuous power rating of the inverter. If there is an overload beyond these specified limits, the AC output of the unit will be shut down permanently. RED LED marked “oVER LoAD” (3) will be lighted and GREEN LED marked “PoWER” (2) will be switched off. The unit will be latched in this shutdown condition and will require manual reset. To reset, switch off the power oN/off switch, wait for 3 minutes and then switch oN again. Before switching on again, remove the cause of the shutdown. - Page 40 seCtIOn 10 | Protections The unit will automatically reset after the hot spot has cooled down to 70°C. Reverse Polarity at the Dc input terminals The Positive of the battery should be connected to the Positive DC input terminal of the inverter (9) and the Negative of the battery should be connected to the Negative DC input terminal of the inverter (8). A reversal of polarity (the Positive of the battery wrongly connected to the Negative DC input terminal of the inverter and the Negative of the battery wrongly connected to the Positive DC input terminal of the inverter) will blow the external / internal DC side fuses. If the DC side fuse is blown, the inverter will be dead. The GREEN LED marked “PoWER” (2) will be switched off and there will be no AC output. inFo Reverse polarity connection is likely to damage the DC input circuitry. The internal fuse(s) should be replaced with the correct size of fuse shown under specifications. If the unit does not work after replacing the fuse(s), it has been permanently damaged and will require repair / replacement (Please read Sec- tion 11 - “Troubleshooting Guide” for more details). cAUtion!
