Inverter Safety

• The inverters are suitable for 12V battery banks or 24V battery banks; Please choose correct voltage inverters and battery!
• Always make sure inverter is in OFF position and disconnect all AC and DC connecting when working on any circuit associated with the inverter.
• Never connect the AC output of the unit directly to an Electrical Breaker Panel/Load Centre which is also fed from the utility power/generator.
• When connecting battery terminals, ensure the polarity of the battery connections is correct. Incorrect polarity may cause permanent damage to the unit.
• Be careful when touching bare terminals of capacitors as they may retain high lethal voltages even after power is removed.

Battery Safety

• Do NOT let the positive (+) and negative (-) terminals of the battery touch each other.
• Use only sealed lead-acid, flooded, lithium battery, ryor gel batteries which must be deep cycle.
• Explosive battery gases may be present while charging. Be certain there is enough ventilation to release the gases.
• Be careful when working with large lead acid batteries. Wear eye protection and have fresh water available in case there is contact with the battery acid.
• Over-charging and excessive gas precipitation may damage the battery plates and activate material shedding on them. Too high of an equalizing charge or too long of one may cause damage. Please carefully review the specific requirements of the battery used in the system.

Pure Sine Wave

• The OLTEANP Power Inverters output a pure sine wave similar to the waveform of the grid power. In a pure sine wave, the voltage rises and falls smoothly with very low harmonic distortion and cleaner utility-like power.
• This gives users stable enough power to operate tools, fans, lights, computers, and other electronics without any interference. Pure sine wave inverters are in many cases more efficient, allowing users to use less energy and allow for more device capability. The main advantage to pure sine wave inverters is that they are used to operate sensitive electronic devices that require a high-quality waveform with little harmonic distortion. Almost any electronic device could be powered using a pure sine wave inverter.

No output voltage    and buzzer sounds continuous or intermittent and shutdown?

| ****

Input battery voltage is low voltage

| •  Recharge the battery.

•  Battery may be too small. Please contact us for recommended battery sizes.

•  Check the cable connections and ensure the cable sizes are sufficient. Use provided cables if included. The shorter and thicker cables the better.

•  One or some of the batteries in

the battery group may be defective, remove the defective battery.

Input battery voltage is high voltage

| •  Check the battery charger is not connected to the battery.

•  Do not use it when the battery is charging Disconnect the solar panel while the battery is fully charged.

•  Confirm whether the input

battery is correct.

Overload| Reduce the load power or choose a bigger inverter.

Over temperature

| •  Turn off the load and let it cool naturally for 10 to 30 minutes. Restart it after it resumes to normal temperature.

•  Reduce the load .

•  Avoid blocking the vent and improve the ventilation condition.

No AC output voltage?

| ****

1.  The power switch is off.

2.  Poor contact with battery .

3.  Inline fuse(if has) may be burnt.

| •  Press the inverter power switch or remote controller power switch to turn it on,

•  Check the cables and make sure they are tightly

connected .

•  Check the inline fuse is fine or remove circuit breaker to test the inverter again.

•  One or some of the batteries in the battery group may be defective, remove the defective battery.

Cannot drive the load even less power than the size of inverter?

| 1.  Power of load is too large, or the actual power of the appliance exceeds the max power of inverter.

2.  The starting power is larger than rated power (especially for appliances with motor, this kind of inductive loads require a large rush of power to start. Even a 80W fridge may need a 1000 watt inverter) .

3.  Battery is too small.

| ****

•  Reduce the load power, or turn on the appliance first, then turn on the inverter.

•  Choose a bigger inverter.

•  Change a bigger battery and ensure fully charged.

•  Choose the shorter and thicker cables.

---|---|---

Starting alarm ?

| The main reason is that the instantaneous current is too large, which leads to the detection of low voltage and triggers

under-voltage alarm.

| ****

Please restart the inverter several times.

Installation

WARNING: Make sure the inverter is in the off position before connecting anything.
CAUTION: Do not over-torque or over-tighten the terminals. This could potentially damage the unit.

Location Recommendations
Never install the inverter in a sealed enclosure with flooded batteries. Gas can accumulate and there is a risk of explosion.

Ensure installation follows the following guidelines:

1. Cool, dry, well-ventilated area — Heat is the worst enemy of electronic equipment. Inverters must be in an area where the fans are not blocked or where they are not hit directly by the sun. They should be in an area free of any kind of moisture and allow for clearance of at least 10” around the unit to provide adequate ventilation.
2. Protection against fire hazard — the unit should be away from any flammable material, liquids, or any other combustible material. The unit can spark and the consequences could be severe.
3. Proximity to battery bank—prevent excessive voltage drop by keeping the unit close to the battery bank and having a properly sized wire going from the battery bank to the inverter.
4. Do not install the inverter in the same compartment as the battery bank because it could serve as a potential fire hazard.
5. Limiting electromagnetic interference (EMI) — ensure the inverter is firmly grounded to a building, vehicle, or earth grounded. Keep the inverter away from EMI receptors such as TVs, radios, and other audio/visual electronics to prevent damage/interference to the equipment.
6. Secure inverter—the inverter could be stand alone or mounted using the outlying terminals on the inverter.
7. The inverter should never be mounted vertically on a vertical surface since it would present a hazard for the fan opening which is crucial for cooling the inverter.

Note: Connection

If you have multiple 12V batteries, please connect them in series or parallel according to the model you ordered(12V for parallel connection, 24V for series connections). Note that connecting(+) terminal and (-) terminal will cause failure. Please connect+(plus), -(minus) each other.

Sizing a Battery Bank

1. The battery is for supplying DC input voltage to the inverter. Its rated voltage should be the same as the rated input voltage of the OLTEANP inverter. Any voltage that exceeds the input voltage range of the inverter will cause the inverter to be overloaded and may damage the inverter.
2. The battery ought to supply enough current for the load. (The load is the amperage or wattage rating of the equipment being powered by the inverter.)A small capacity battery cannot supply enough power for large electrical equipment and it will cause the inverter to be under-voltage. For determining the required battery capacity size is shown below for reference:
3. Determine the Watts (Amps *Volts) of the load (Each appliance has technical specifications indicating the wattage or voltage and amperage required for operation)
4. Utilize the formula Amps=Watts/Volts
5. Inverter consumption=Amps*10% (Due to inverter efficiency of 90%, the recommended estimate for the calculation is 10%)
6. Estimated load runtime (The capacity of the battery depends on the load wattage and runtime. Most loads are not constant, so estimation is essential.)
7. Determine Ah(Ampere-Hour) of the battery

Example: Using a 12VDC battery to run a 1200 Watts hotplate for 2 hours needs at least 220Ah battery.(10%Inverter consumption)

The calculations are as follows:

Utilize the formula Amps=Watts/Volts| 1200 Watts /12 Volts = 100 Amps
Inverter consumption| 100 Ampsx10%=10Amps
Load runtime = 2 hours| (100 Amps+10)x2 hours =220 Ah

Conclusion: At least a 220 Ah battery must be selected in order to use the 1200 watts hotplate at 2 hours a day. However, determining the capacity of the battery is also dependent on the battery that is able to handle repeated discharge/charge cycles.

• This is just an example. Actual quantities vary by battery capacity and rates.
• Running wattage may fluctuate. To power the hotplate in the example, must use an inverter of at least 1500 watts.

DC Side Connection

• The OLTEANP Pure Sine Wave Inverters are suitable for 12V battery bank systems ONLY. Not following the minimum DC requirement will cause irreversible damage to the unit.
• Be careful of the positive and negative poles. Reversing the poles might cause permanent damage to the inverter. It will surely blow the internal fuse.
• Damage to the OLTEANP inverters due to reverse polarity is NOT covered by warranty.
• The input terminals of the inverters have large capacitors connected to them. Once a positive and negative wire are connected to the terminals, it will complete the circuit, and commence drawing a heavy current momentarily. As a result, there may be a sparking occurring even if the inverter is in the off position. To minimize sparking, it is recommended that the user have the appropriate size wire feeding into the inverters.

AC Side Operation

1. Connect electronic devices to electrical socket (s) on the inverter. Flip inverter power to ON position (on AC side)
2. When finished, switch AC devices off first, then turn off the inverter switch.
   • CAUTION : Avoid switching on the inverter with the load (electronic devices) already switched on. This may trigger an overload since some electronic devices have an initial high power surge to start.
   • CAUTION : When switching off the inverter, turn off the electronic devices first. Although the inverter is off, the capacitors will still have a charge, so the DC and AC terminals must be disconnected if altering the circuitry.
