OPERATION

AC In

When power button is switched to”on”,the product is fully functional.
The inverter will come into operation and the green LED “AC ln”will light up.

Inverter Mode

In the event of a grid failure,or generator power being disconnected, the unit switches to inverter mode and takes over supply to the connected loads.This happens so fast (less than 10 milliseconds) that computers and other electronic equipment will continue to operate without disruption.The green LED light of “Inverter” indicates on the LCD panel

Charging Mode

In the event of restoration of grid,or generator power,the Inverter commences charging.The”AC ln”green LED light comes up,and the orange”Charge”light starts blinking.When the batteries are fully charged,the blinking orange light changes to Solid Orange.

Alarm Mode

In the event of high battery discharge,and its gets close to the battery cutoff level,the red”Alarm”light starts showing,and it is accompanied with a beeping sound,this continues until the units gets to the battery voltage cutoff level and its powers down automatically,except there is a restoration of grid supply in which case it changes back to gharging mode.

Bypass Functionality:

When the power control button is switched to “OFF”,and there is a grid or generator supply,the inverter supplies output to the load and also charges.
When the power control button is switched to”OFF”,and there is no grid or generator supply,the inverter supplies does not supply output to the load.

Saver Mode

When the power control button is switched to”SAVER”,and there is no supply of grid,the inverter’s AC output will not be supplied until a load greater than 15 watts is connected to the inverter. It automatically detects the connected load every 15 seconds.

INSTALLATION

WARNING

A qualified electrician should install this product.

Locating and Mounting the Inverter

The product must be installed in a dry and well-ventilated area,as close as possible to the batteries.There should be a clear space of at least 10cm around the appliance for cooling.

Excessively high ambient temperature will result in the following:

Reduced service life.
Reduced charging current.
Reduced peak capacity,or shutdown of the inverter.

Never mount the appliance directly above the batteries. The product is suitable for wall mounting.For mounting see Fig.1.
The appliance can be mounted horizontally as well as vertically;vertical mounting is preferable.The vertical position offers optimum cooling. The interior of the product must remain accessible after installation. Try and keep the distance between the product and the battery to a minimum in order to minimize cable voltage losses.
For safety purposes,this product should be installed in a heat-resistant environment if it is used with equipment where a substantial amount of power is to be converted.You should prevent the presence of e.g. chemicals,synthetic components,curtains or other textiles,etc.,in the immediate vicinity.

AC Wiring

This is a Safety Class I product (supplied with a protective grounding terminal).Uninterruptible protective grounding must be provided at the AC input and/or output terminals and/or chassis grounding point located externally on the product

AC Wiring should be connected in the following order:

AC INPUT (Source)
AC OUTPUT (Load)

AC Input: The inverter comes installed with Input protection circuit breaker.This should be switched off before the cable is installed. Remove the AC wiring compartment cover to gain access to the AC terminal strip inside.
Run the three conductors AC INPUT (source) wiring into the wiring compartment.Connect the AC INPUT ground wire first to the ground terminal (ground symbol with circle around it),and then connect the AC.
INPUT line (L) and neutral wire (N) to the corresponding AC input terminals.
AC Output: The inverter comes installed with Input protection circuit breaker.This should be switched off before the cable is installed.
In a similar manner,connect the AC OUTPUT (load) wiring to the Inverter AC output terminal as was done on the AC Input After wiring ,double check and review all connections to make sure the wires are in the correct terminals and the terminals are tight

To ensure the best performance from your inverter system.do not use old or untested batteries.Batteries should be of the same size.type, rating.and age.
AC Safety Grounding: During the AC wiring installation.AC input and output ground wires are connected to the inverter.The AC input ground wire must connect to the incoming ground from your AC utility source. The AC output ground wire should go to the grounding point for your loads (e.g.a distribution panel ground bus).

DC Wiring

**WARNING**

DO NOT connect the DC wires from the battery bank to the inverter until:

All AC wiring is complete,
The correct DC and AC protection switches are OFF
The correct DC voltage and polarity have been verified

Depending upon the type of batteries you use in the installation (6 or 12 VDC),the batteries must be wired in series,parallel,or series-parallel.
The interconnecting DC wires must be sized and rated exactly the same as those that are used between the battery bank and the inverter.
To ensure the best performance from your inverter system.do not use old or untested batteries.Batteries should be of the same size.type, rating,and age.

procedure

In order to fully utilize the full capacity of the product.batteries with sufficient capacity and battery cables with sufficient cross section should be used.

Proceed as follows to connect the battery cables:

WARNING

Use an insulated box spanner in order to avoid shorting the battery.
Avoid shorting the battery cables.

Connect the battery cables: the + (red) on the left and the-(black) on the right.to the battery.Reverse polarity connection (+ to – and – to +) will cause damage to the product.(Safety fuse inside the Inverter unit can be damaged)
The DC overcurrent device (i.e.,fuse or circuit breaker) must be placed in the positive (RED) DC cable line between the inverter’s positive DC terminal and the battery’s positive terminal (RED);as close to the battery as possible.

A brief spark or arc may occur when connecting the battery cables to the inverter DC terminals;this is normal and due to the inverter’s internal capacitors being charged.
All wiring to the battery terminals should be checked periodically (once a month) for proper tightening Secure the nuts tightly in order to reduce the contact resistance as much as possible.
Be aware that over-tightening or misthreading the nuts on the DC terminals can cause the bolts to strip and snap/break off.

DC Wiring Size

It is important to use the correct sized DC wire to achieve maximum efficiency from the system and to reduce fire hazards associated with overheating.Always keep your wire runs as short as practical to prevent low voltage shutdowns and to keep the DC breaker from nuisance tripping (or open fuses) because of increased current draw.
The correct minimum DC wiresize (and corresponding overcurrent device) is required in order to reduce stress on the inverter.minimize voltage drops,increase system efficiency and ensure the inverter’s ability to surge heavy loads.
If the distance from the inverter to the battery bank is ~5 feet,use a minimum DC wire size of #2 AWG (33.6 mm2).lf the distance between the inverter and the battery is>5 feet.the DC wire will need to be increased.Longer distances cause an increase in resistance,which affects the performance of the inverter.

TROUBLESHOOTING

Proceed as follows for quick detection of common faults.DC loads must be disconnected from the batteries and the AC loads must be disconnected from the inverter before the inverter and/or battery charger is tested.
Consult your local dealer/repair center if the fault cannot be resolved.

Tab.V

Problem	Cause	Solution
The inverter fails to operate when switched on	Battery terminal not firm

Tighten the battery terminals.
Continuous spark from the inverter terminal| Battery terminal reversal| Check and connect the cable to the right terminal lead.
No output from inverter| Output cable terminals loosed| Open the casing and connect the output cable terminals firm to the appropriate lead.
Inverter not charging battery| input power less than(<) 150 /83-96VAC| A step- up stabilizer of rating higher than the inverter should be installed.
Continuous alarm when the inverter is loaded| Overloading condition| Check the loads and disconnect heavier loads.
