Pre Installation Information

Before installing your Sine Wave Inverter, it is important that you have appropriately sized batteries. A battery which is too small will not allow the inverter to perform to its full specification. Battery performance will vary between different styles of batteries, for example a Deep Cycle battery will tolerate deep discharges on a regular basis much better than a cranking battery, whereas a cranking battery may provide higher Volts when high battery current is being drawn ( e.g. your Inverter is starting a motor or Television). Normally a deep cycle battery would be selected for a RAPS application.

The table below gives a guide to the minimum battery capacity required:

See page 12 for additional notes on battery sizing.

Minimum Battery Capacity Required

Battery Terminology

I = CurrentThis is the measure of electrical power flowing. This is expressed in Amps. For example, I = 6A means 6 Amps.

Ah = Ampere Hours

This is the amount of energy a battery can store. In theory this means a 600Ah battery could supply 1 Ampfor 600 hours. C/20 is the 20 hour rate or 600/20 = 30A for 20 hours.

CCA = Cold Cranking AmpsThis is the maximum amount of current that the battery can supply for a short period of time.

NOTE: Batteries joined in series (+ to -) will increase the voltage but not the Ah. Batteries joined in parallel (+ to +, - to -) will increase the Ah but not the voltage.

For example: 4 x 12V / 600Ah batteries joined in series = 48V / 600Ah 2 x 12V / 600Ah batteries joined in parallel = 12V / 1200Ah

There should be no more than 2 batteries in parallel.

Mechanical Requirements

• After choosing the correct batteries you must choose a suitable enclosure to mount the Inverter. Select a site which is dry, free of salt or moisture laden air, dust, exhaust or battery gases and access to rodents. Power sheds MUST have 4 walls and a lockable door.

• NEVER mount the inverter directly above the batteries or close to a tin roof, condensation may form.

• There are many advantages in wall mounting the unit. Inspection and operation is more convenient.

• Mount the inverter between 1 and 3 metres from the batteries, on a suitably solid vertical wall. Allow a cooling space of at least 200mm all around the inverter. Placing the inverter in a cupboard or small enclosure may reduce the available output power.

The installation site should not be susceptible to temperatures in excess of 500C.

• It is NOT recommended your inverter be mounted close to sleeping or living areas. The inverter can make audible noises at times.

We refer you to Australian Standard AS4509 for further information regarding home power installations.

Electrical Requirements

• DC input voltage of the inverter must be the same as the battery bank voltage. See specifications for your model. High ripple voltage from battery chargers, poor condition batteries or loose terminals MUST be avoided.

• DC cabling must be connected to the correct polarity terminal of the battery bank (red = positive, black = negative).

• It is Not recommended that the DC cables to the Inverter be extended. If it is necessary, then you MUST increase the wire size. Consult your Supplier/Installer for this calculation.

• Do not connect 240V AC or any other power source to the 240V output of the inverter as this will result in damage to the inverter and can be detected by the repairer. An AC circuit breaker (C curve) must be used on the Inverter output. Use the 30 minute rating of the Inverter plus 20%.

• If you need to switch from Inverter to Generator or Shore Power it is absolutely critical that there is no possibility of AC feeding back to the inverter. Should this happen you may see early failure of your inverter and will not be covered by your warranty.

Installation

WARNING: Please read these instructions thoroughly before commencing installation. Installation should be performed by a competent professional electrical / renewable energy installer, as dangerous voltage can be present.

The following steps should be completed in the order presented in this section.

1. MOUNTING

a) Unpack your Inverter from its shipping container and inspect the unit for any transit damage, report any concerns immediately to your supplier.

b) Remove the lid of the Inverter by loosening three posidrive screws near the base of the lid (3 on each side) and removing 5 posidrive screws on the face.

c) Mount the Inverter to a suitable surface, paying close attention to the mounting requirements as detailed earlier .

Important: All AC wiring must comply with relevant Australian and local standards, and be performed by a licensed electrician to satisfy warranty requirements and conditions.

Figure 1. Top view of internal Din Rail



2. AC WIRING

a) Connect active, neutral and earth to the appropriate terminals on the DIN rail inside the Inverter. It is possible to mount a RCD / Safety Switch or AC breaker on the internal DIN rail of the inverter, by replacing the existing terminals. After install-ing these items push out the plastic pole fillers on the lid so that the breaker can penetrate the lid.

b) Tighten the cable gland and replace the lid, being sure to reconnect the lid earth strap.

c) Wiring to the AC loads MUST be carried out in accordance with appropriate standards, such as AS3000. If the AC load is to be switched between the Inverter and another AC source such as a generator, it is critical that no AC from the genera-tor can be fed into the Inverter. Failure to do so will severely damage your inverter and will void your warranty. This type of damage can be detected by your repairer. See elsewhere in this manual for a suggested diagram of an AC load switch.

d) The inverter metal work must be earthed, this is automatically achieved by wiring the AC output earth terminal to the util-ity ground or installation earth.

RCD and RCDB suffix only

These special versions of the Everest feature added RCD (residual current detection) protection for the AC outputs to prevent shock hazard.

The RCD version features a DIN rail mounted RCD unit inside the inverter, the AC connection being made to the DIN rail terminal strip in the usual way.

The RCDB version features a front panel mounted dual GPO/RCD assembly, and is designed for mobile/vehicle applications. Connection is made by suitable 10A GPO plugs.

The RCD trip current is 30mA in both cases.

Important

In order for the RCD to function correctly a factory fitted link is installed on the RCD between the inverter AC output neutral (N) and the chassis earth (E).

When the appliance is installed the chassis earth must be connected to an effective external ground.

In the case of mobile units the chassis of the vehicle will normally be connected to the chassis of the inverter and the combined chassis assembly must be connected to a ground spike or other reliable earth bond.

Refer to local work practice and wiring regulations.

3. DC WIRING

The primary consideration is to ensure that the battery bank voltage matches the DC input voltage rating of the inverter. The batteries should be located only a short distance from the inverter in order to obtain best results, but not closer than 500mm. A battery fuse MUST be installed no further than 500mm from the battery to protect all wiring connected to the battery. We suggest the use of a motor start fuse in both battery leads. See table on page 4 for sizing. Your installer should determine the exact size of fuse.

Before making any connections, ensure the DC circuit breaker is in the OFF (down) position. Connect the inverter to the battery terminals via the battery fuse, ensuring the correct polarity (RED = positive).

4. START-UP PROCEDURE

a) Check battery condition and voltage are within specifications.

b) Ensure ON / OFF switch is in the OFF position.

c) Ensure the DC circuit breaker is set to the OFF (down) position.

d) Ensure no AC load is connected.

e) Switch DC circuit breaker to the ON (up) position.

f) Switch ON / OFF switch to the ON position. If all is well LED 1 will be flashing green or orange. This indicates all parameters are normal and the unit is in Standby waiting for an AC load to be switched ON.

g) Apply AC load.



RCD Test (where fitted)

After installation, ensure the RCD unit is reset by pulling up the breaker toggle switch (type RCD) or by pressing the blue button fully home until it clicks (RCDB type). Power on the inverter and press the ‘test’ button on the RCD and ensure it trips. Repeat this test each time before the appliance is used to guarantee continued protection.

Reset the unit by resetting the breaker (RCD type) or pressing the blue button back fully home (RCDB type).

Should the RCD unit require replacement, a licensed electrician may replace the RCDB type from the front of the unit without removing the cover.

Controls and Display

LED 1 (top LED) - normally GreenLED 1 is a multicolour LED. In normal operation the LED will be GREEN. Flashing green or orange* indicates the inverter is in Standby mode, waiting for an AC load to be turned on. Steady green indicates the inverter is delivering an AC output.

LED 1 showing RED indicates that the inverter has been overloaded. This indicates the load may demand more current than the inverter can safely supply. If this condition persists for more than ten seconds the inverter will disconnect. Check for possible overload / shorting conditions in the AC load and if necessary re-audit your energy consumption requirements.

LED 2 (middle LED) - normally OffLED 2 shining RED indicates that the temperature inside the unit exceeds safe operating limits. This may be due to overloading or insufficient ventilation. Please check loads carefully and ensure the unit is well ventilated.

LED 3 (bottom LED) - normally OffLED 3 flashing RED indicates the DC input voltage is either too high or too low. Reduce the battery voltage by removing the charging source or increase the battery voltage by recharging the batteries. If low voltage is showing when large loads are present, the batteries may need to be increased in capacity.

* Dependent on model.



Load Sense Feature and Adjustment

Your Solar Energy Australia inverter features an automatic load sensing circuit that allows the inverter to enter a low power standby mode when no AC load is switched on. The inverter will regularly pulse just a few cycles of AC voltage to test for a load. When an AC load is switched on which is above a user adjustable limit, the inverter will immediately start and run, until such time as the load is switched off or the load’s current draw falls below the threshold that has been set. The adjustment range is approximately 7 - 40W. Some very small loads, phone chargers and the like may not draw sufficient current to start the inverter. In these cases the inverter should be set to ‘always on’, see below.

Important: The automatic load sensing feature is adjusted slightly differently between the various models of the Everest, the higher power units being fitted with an additional circuit to enhance the load sensing sensitivity.

As the adjustment is very sensitive, it may take more than one attempt to get the setting ‘spot on’. Wait 10 seconds between adjustments for the inverter to stabilise. Although the instructions may seem complicated the procedure becomes intuitive after a few attempts. Use a small screwdriver to adjust the trimpot taking care not to apply too much force to it.

Once set, the threshold should not require constant re-adjustment, although there will be minor variations over battery voltage and temperature.

For the SEAP-12-2K0, SEAP-24-2K2, SEAP-48-2K4

a) Turn off all the AC loads in the home, keeping the inverter connected to the house circuits. Some loads, such as TVs, must be turned off at the power point as they can still represent a small load to the inverter.

b) Turn the trimpot fully clockwise, in this position the inverter will run continuously and the indicator LED 1 will be steady green. If it is wished to override the auto sense function leave the trimpot in this position. Adjust the trimpot anticlockwise until the LED 1 starts to flash orange. The unit is now in standby mode.

c) Turn on a small AC load in the home, such as a low energy light bulb or similar. The unit should now turn on and deliver 240VAC, the LED 1 indicator will light green continuously. If the LED 1 is flashing orange and the load is pulsing, or the LED 1 is steady orange and the inverter is cycling on and off every 10 seconds approximately, then the current being taken by the load is just not quite sufficient to latch the inverter on. Turn the trimpot slightly clockwise to increase sensitivity until the LED lights green.

d) Turn off the AC load and the LED 1 indicator will light orange continuously for 10 seconds to indicate the inverter is returning to standby mode. Once in standby the LED 1 should resume flashing orange. If it is orange continuously then reduce the sensitivity by turning the trimpot slightly anticlockwise.

In summary, if the unit fails to start up adjust the trim pot clockwise very slightly to increase the sensitivity. If the unit runs continuously adjust the trimpot anticlockwise very slightly to reduce the sensitivity.

For the SEAP-24-3K0 and the SEAP-48-3K8

a) Turn off all the AC loads in the home, keeping the inverter connected to the house circuits. Some loads, such as TVs must be turned off at the power point as they can still represent a small load to the inverter.

b) Turn the trimpot fully anticlockwise, in this position the inverter will run continuously and the indicator LED 1 will be steady green. If it is wished to override the auto sense function leave the trimpot in this position. Slowly turn the trimpot clockwise until the indicator LED 1 is flashing green, the unit is now in standby mode.

c) Turn on a small AC load in the home, such as a low energy light bulb or similar. The unit should now turn on and deliver 240VAC to the load, the LED 1 indicator will light green continuously. If it stays flashing and power to the load is intermittent, increase the sensitivity by turning the trimpot anticlockwise slightly to increase sensitivity.

d) Turn off the AC load and the unit should revert to standby mode, LED 1 will illuminate orange for about 10 seconds to warn the inverter is returning to standby, after 10 seconds the inverter will enter standby with the LED 1 flashing green. If LED 1 is showing orange whilst the AC is on, then the threshold is set marginally. Adjust the trimpot slightly anticlockwise to increase the sensitivity, the LED 1 should then turn green.

In summary, if the unit fails to start up adjust the trimpot anticlockwise very slightly to increase the sensitivity. If the unit runs continuously adjust the trim pot clockwise very slightly to reduce the sensitivity.



Overriding the Auto Load Sensing Feature

Some loads may be too small to be detected by the load sense feature, in these cases you may need to configure the inverter ‘always on’, bearing in mind this will be more wasteful of power.

For the SEAP-12-2K0, SEAP-24-2K2, SEAP-48-2K4

Turn the trimpot fully clockwise, the inverter will always be on.

For the SEAP-24-3K0 and the SEAP-48-3K8

Turn the trimpot fully anticlockwise, the inverter will always be on.

Alarm Contacts(Models SEAP-12-2K0, SEAP-24-3K0 AND SEAP-48-3K8 only)

Located on the right hand side of the Printed Circuit Board are two spare connectors, the top connector provides a voltage free set of contacts with a maximum rating of 2 Amps. To access this connector you will require P/No 15-1177-02 available from Solar Energy Australia.These contacts will close with the following conditions:

Low Battery Volts

As battery volts decrease, the contacts will close 1 Volt above shut down. The contacts will reopen when normalbattery volts are restored.

Over Temperature

Contacts will close just before the inverter is about to shutdown due to the inverter becoming too hot. The contactswill reopen once normal temperature has been restored.

Overload

If the inverter has been overloaded the contacts will close as the inverter shuts down, reopening again when theload has been reduced and the inverter has reset itself.

Applications

The 2 Amp switching capability of these contacts could be used to energise an external relay or activate an external timer. By activating an external timer you will remove the possibility of an auto start generator being turned on or off at short intervals due to large loads and small or old batteries.

• Provide an early warning of shutdown via an alarm or visual indicator.

• Auto start a generator.

• Switch over to mains electricity.

Remote on / Off (all models)A 2 pin connector is located on the LED indicator PCB. This connector allows ON / OFF control of the inverter via a remote two position switch.

To activate REMOTE control ON / OFF, set SW2 to the reset position. The setting of Pot 1 will not be affected.

The remote On / Off feature can be very useful where it is necessary to shut down the inverter completely but easy access to the inverter is not possible, for example, the remote switch may be placed in the cabin of a vehicle while the inverter is mounted elsewhere.

Order connector SEA part No. 15-1177-02 if you wish to make use of this facility.



Troubleshooting

Inverter shuts down due to Over TemperatureYour inverter will safely provide the output power as described in the technical data section in the conditions specified. If your inverter shuts down and indicates over temperature, it may be that you have exceeded one of the parameters.

Check the following:

a) Ensure the inverter has adequate ventilation; insufficient ventilation can severely restrict the power output of your inverter.

b) Ensure the true power rating of your appliance (including power factor) does not exceed the rating of your inverter.

Inverter shuts down when trying to start a load

When starting a load such as a motor it may cause the inverter to shut down. If this is the case:

a) Ensure the battery voltage is within spec when the appliance is trying to start. You may need to increase the size of your batteries.

b) If battery voltage is OK then the inverter may be too small. Consult your Solar Energy Australia representative. Continual overloading of an Inverter may cause early failure.

Screeching noise on radio when inverter is operating

Your Solar Energy Australia inverter is manufactured to the highest standards for the reduction of EMI (Electro Magnetic Interference). It is still possible however that in extreme cases, interference may be noticeable in radio’s or television sets. Below are some suggestions to try to reduce this noise.

a) If possible run a heavy gauge earth wire from battery negative to a moist ground stake. Also connect this to the earth stud on the chassis of the inverter (where fitted).

b) Separate AC and DC wiring.

c) Improve signal strength of receiver by improving antenna.

d) Reposition inverter as far away from receiver as possible.

Inverter stays shut down for a long time after overload

The inverter is responding to either a severe overload or repeated overloads. Turn the inverters circuit breaker OFF for 30 seconds and then reconnect. If the cause of the original shutdown is still present, the inverter will shut down again. Reduce load or allow inverter to cool down.

How long will my battery last?Assumptions

Firstly some assumptions, let’s consider a system based around a popular 12V lead acid gel battery.

1) You will only ever discharge your battery by 50% to preserve its life

2) The battery is so sized as a typical discharge will occur at the C/20 rate, where C is the nominal capacity of the battery, 600Ah in this example.

a. C/20 is the rate at most gel batteries spec their rated capacity

b. For a 600 ampere/hour (Ah) rated capacity battery C/20 is 30A

c. This is also known as the ‘20hour rate’

3) The overall efficiency is around 90% for a 12Volt system.

a. This takes into account inverter and cabling losses

b. It will be slightly higher for 24V and higher again for 48V

OK, let’s make an estimation for the case above.



Step 1

Estimate the total power of the appliances you wish to power from your inverter in watts. Lets say you have 5 X 13W lamps, a DVD player drawing 40W and a TV drawing 167W. That’s 272W total. You can get the power from the appliance rating plate or the handbook.

Next, work out the estimated DC current draw by dividing the power by 10 for a 12V system, 22 for a 24V system and 45 for a 48V system. These numbers factor in the approximate efficiency for you.

For a 12V system the DC current will be approximately 272/10=27A

Check this is less than or equal to the C/20 rate, in the above example this is 600/20=30A so we are OK, if not see below, ‘Why is this only an estimate?’ and ‘Battery sizing’.

Step 2

Take the ampere hour (Ah capacity) figure of your battery and divide by 2 (as you are only going to use 50% of the capacity to prolong the battery life and give some margin for error and emergencies etc) So, if we have a 600Ah battery this gives us 300Ah capacity we can actually draw on.

Step 3

Divide the current draw into the battery capacity, in the example 300/27 = 11 hours. Thus the example battery will support the requirement for just under half a day.

Why is this only an estimate?

Gel battery capacities are generally stated at the C/20 rate (or the ‘20hour’ rate), 30A for the example above. For a higher discharge rate the effective capacity will be reduced.

i.e. a 60A discharge would be C/10 for the above example battery but its capacity Ah rating at C/10 might only be 480Ah. So we have doubled the discharge rate, but instead of half the time (for a 50% discharge), 5 hours, the battery will only last for 4. For a more accurate estimate refer to the battery manufacturers specification for the capacity at the actual discharge rate you intend to use.

In summary, minimise heavy loads to get the best capacity from your battery. Helpfully, in the real world heavy loads tend to be intermittent, which gives the battery time to recover. For example, a toaster or hairdryer. This tends to help the battery, but then again battery capacity is also reduced in cold weather.

Heavy continuous loads, such as air-conditioning, will damage either battery or inverter or both if the system is not sized correctly. For most systems operation of major electrical loads continuously is not an option as to size the system to do this would be uneconomic. Lifestyle and appliance choices make a major impact on any RAPS installation. Please consult your installer for advice.

Additional notes on battery sizingPlease refer to page 4 for our general recommendations. From the above it will be seen that it is better to be conservative with choosing a battery. Batteries that are too small, or of the wrong type, give disappointing service life and may lead to inverter damage, as their internal resistance will be too high to supply the current demands of the inverter, particularly during surges, when the current demand may be three times nominal.

If your continuous current draw is much above the battery manufacturers quoted discharge rate for the rated capacity (this varies between manufacturers and battery type but is generally between C/5 for large wet cell types to C/20 for gel types), then the chances are you need to use a bigger battery. As the currents are that much higher, and the efficiency lower, this is more likely to occur in the case of a 12V system, all else being equal. To increase the Ah capacity it is possible to put a maximum of two batteries (or strings of batteries) in parallel. These will double the Ah capacity for the same voltage.

How can I tell if my Inverter is In Standby if I am in the house?It is important to keep your inverter in standby whenever no power is being used. A power point with a neon indicator or a child’s night light will mimic the output of the inverter. Eg, these will flash when the inverter is in standby. This feature will save unnecessary battery drain.
