Structure

Output panel

ON/OFF switch …….. The ON/OFF switch turns the control circuit in the inverter on, off. It doesn’t need to be disconnected power from the inverter when you don’t use it.
Remote ON/OFF jack …….. The inverter has a jack that interfaces with the optional remote ON/OFF switch, it allows you to mount the inverter out of sight and turn ON or OFF from a conveniently located panel ( remote control panel ) . It also has ON/OFF switch and indicator light showing that the inverter is ON or OFF on the remote control panel.
VOLTS ( battery voltage ) indicator …….. The battery voltage indicator displays the voltage at the input terminal of the inverter. At low currents input, the voltage is very close to the battery voltage. At high current input, the voltage will be lower than the battery voltage because of the voltage drop across the cables and connections.
AMPS ( battery current ) indicator …….. The battery current indicator displays the current drawn from the battery by the inverter. It won’t indicate current drawn by another load also connected to the battery. Current should be in the green zone for continuous operation. The inverter will operate for several minutes when the current is at the yellow zone. If the current is at the red zone, it will result in protective to shut down the inverter.
POWER indicator …….. After you connected the DC cables each with the battery and the inverter and switch on the inverter, the power indicator illuminates w/green color, it indicates ready for use.
OVER TEMP indicator …….. The OVER TEMP indicator illuminates w/yellow color and the alarm sound when the inverter overheated and shut down. The reason for the inverter being overheated is that it has been operated with power levels above its 2500W continuous output rating, or installed in a location that doesn’t allow it to dissipate heat properly. The inverter will restart automatically once it has cooled.
OVERLOAD indicator …….. The OVERLOAD indicator illuminates w/red color when the inverter shutdown because of a severe overload. To restart the inverter, please switch the ON/OFF switch ( or ON/OFF switch on the remote control panel ) to OFF, and correct the fault condition ( remove or reduce the load ), the switch back to ON .
Alarm indicator …….. An audible alarm will sound when any of the following conditions occur:
Over temperature condition.
Low battery alarm ( ＜10V for 2500W/12V inverter , ＜21.5V for 2500W/24V inverter ).
Low battery shutdown (＜9.5V for 2500W/12V inverter, ＜20V for 2500W/24V inverter ).
AC outlet …….. You can plug your AC loads directly into this outlet.
Caution: If making a permanent AC connection to the inverter, please attend to 110V or 220V AC power is potentially lethal, don’t work on AC wiring while the wiring is connected to the inverter ( even if it is switched off ) unless the DC power source is physically disconnected from the inverter. Also don’t work on AC wiring if it is connected to another AC power source such as a generator or the utility line.

Input panel and instruction

Fan …….. The fan disperses the inverter’s internal heat during the inverter operation.
Terminal connector / positive pole ( red , + ) & negative pole ( black , – ) …….. The terminal connector allows you to connect the ends of DC cables with the inverter, the red wire is connected with the positive pole ( red, + ) and the black wire is connected with a negative pole ( black ,- ). And the other ends of DC cables are connected to battery, also the red wire with a positive – pole ( red, + ) and the black wire with a negative pole ( black, )
Caution: Please don’t reverse the polarity.
Chassis ground lug ……..
The inverter has a lug which is to connect the chassis of the inverter, therefore, the inverter’s AC output ground to your AC distribution system ground. The ground wire in the AC junction box on the output panel of the inverter is connected to the chassis. The chassis ground lug must be connected to a grounding point, which will very dependent on where the inverter is installed. In a vehicle, connect the chassis ground lug to the chassis of the vehicle. In a boat, connect to the boat’s grounding system. In a fixed location, connect to earth ground by a ground rod ( a metal rod pounded into the earth ), or other proper service entrance ground. Use a # 12 AWG or larger copper wire ( preferably with green/yellow insulation ) to connect the chassis ground lug to the grounding point. The neutral ( common ) conductor of the inverter’s AC output circuit is connected to the chassis ground. Therefore, when the chassis is connected to the ground, the neutral conductor will also be grounded. This conforms to national electrical code requirements that separately derived AC sources ( such as inverters and generators ) have their neutral conductors tied to the ground in the same way that the neutral conductor from the utility line is tied to the ground at the AC breaker panel.
Caution: Don’t operate the 2500W inverter without connecting it to the ground. An electrical shock hazard may result.

Operating instruction

Operating ……..Firstly, please connect the inverter tightly to your battery or other DC power source by DC cable with terminals. Please attend to the polarity, connect the positive pole ( red, + ) on the input panel of the inverter to the positive pole ( red, + ) of the battery or other DC power source and the negative pole ( black, ) on the input panel of the inverter to the negative pole ( black, ) of the battery or other DC power source.
Caution: Please don’t reverse the polarity. If reverse polarity connection ( positive to negative ), it will blow the fuses in the inverter and may permanently damage the inverter. Please don’t use “ alligator “ clips and always ensure the ON/OFF switch on the output panel of the inverter is switched to the OFF position before connecting the battery or other DC power source.
Caution: Please don’t operate the inverter directly from a charging source such as an alternator or a solar panel. It must be connected to a battery or a well-regulated and high-current DC power supply to work properly . The inverter is now ready to deliver AC power to your loads. If you are operating several load from the inverter, turn them on separately after the inverter is already turned on. This will ensure that the inverter doesn’t have to deliver the starting currents for all the loads at once . It is recommended that you earth the inverter to the chassis of your vehicle, boat , …… etc., or to your earth leakage circuit in a house ( or a stake in the ground ) . This step will avoid electrical safety hazards.
Load …….. Caution: Please don’t operate this inverter with a load in excess of 2500W or full load for an extended period of time to avoid overload or temperature.

Permanent installation :

Where to install ……..
The inverter should be installed in a location that meets the following requirements:
- Dry: Don’t allow water to drip or splash on the inverter.
- cool: Ambient air temperature should be kept between 0 ~ 25 ˚ C ( 32 ~ 77 ˚ F
- Ventilated: ensure that the inverter in a compartment that is ventilated and you need to allow at least 1 inch ( 2.5 cm ) of clearance around the inverter for airflow. Ensure that ventilation openings on the output panel and input panel aren’t obstructed.
  Caution: To reduce the fire hazard and avoid overheating, please don’t cover or obstruct the ventilation openings of the inverter. And don’t put it in a zero clearance compartment.
- Safe: Don’t install the inverter in the same compartment of storing flammable matters such as gasoline, gas, nitroglycerin, ……….
- Close to battery: install the inverter as close to the battery as possible in order to minimize the length of DC cables, but don’t put it in the same compartment. It is better and cheaper to run loner AC wires than longer DC cables, because of the much lower current is the AC wires .
  Caution: Some components of the inverter tend to produce arcs or sparks, for reducing the risk of fire and explosion, please don’t install the inverter in the compartment containing batteries and flammable matters.
How to install …….. Mount the inverter horizontally or vertically on a flat surface using the mounting flanges on the output panel and input panel. Mounting hardware should be corrosion-resistant and larger. Never drop the inverter as it is a sensitive electrical product and damage will occur.
Battery recommended …….. The battery you use strongly affects the performance you can expect from the inverter, it is very important to correct the size and type of battery.
DC cable recommended …….. Proper wire and wiring is very important for the safe and proper operating of the inverter. Because the 2500W inverter has a low voltage, high current input, and low resistance wiring between the battery and the inverter is essential to deliver the maximum amount of usable energy to your load. Don’t waste the investment you have made in batteries and a highly efficient inverter by using undersized wires.
2500W/12V：：#38 2AWG
2500W/24V：：#22 4AWG
Caution: Don’t tin the cable ends with solder owing to it will result in a poor connection.

Maintenance

To always keep the inverter operating normally, please clean the exterior of the unit periodically with an alcoholic cloth ( or damp cloth ) to prevent the accumulation of dust and dirt. The air intake (fan/ventilation openings ) on the input panel and air exhaust slots on the output panel is especially prone to accumulate dust and dirt. A regular maintenance check is recommended, and the screws on the DC input terminals should be tightened periodically.

Caution: If after the above easy troubleshooting, this inverter still doesn’t work, please return it to us or have a qualified electrician check and replace it. Don’t open the case or cut out the cord yourself.

Caution:

Don’t use the inverter with the following rechargeable appliance …….. Certain recharges for small nickel-cadmium batteries can be damaged if connected to the inverter. Two particular types of equipment are prone to this problem :
- Small battery-operated appliances such as flashlights, razors, and nightlights can be plugged directly into the AC receptacle to recharge.
- Certain battery chargers for battery packs are used in hand power tools. These chargers will have an awarning label stating that dangerous voltages are present at the battery terminals.
  This problem doesn’t occur with the vast majority of battery operating equipment. Most of this equipment uses a separate charger or transformer that is plugged into the AC receptacle and produces the lower voltage output. If the label on the AC adaptor or charger states that produces a low AC or DC voltage output ( less than 30 volts ), the inverter will power this adaptor or charger safely without trouble.
Use the correct size and type of battery ……..
The 12V inverter must be connected only to the battery with a nominal output voltage of 12V volts. The 12 V inverter won’t operate from a 6 volts battery and will be damaged if it is connected to a 24 volts battery. The 24V inverter must be connected only to a 24 volts battery, and won’t operate from a 6 or 12 volts battery . For most applications of 2500W inverter, we recommend that you use one or more deep cycle batteries in parallel. More capacity is better since you will have more reserve capacity and your battery won’t be discharged as deeply.
Always place this inverter in an environment as follows:

Well ventilated and ambient air temperature should be kept between 0 ~ 25 ˚ C ( 32 ~ 77 ˚ F
Stay away from water, moisture, oil, gasoline, gas, and any flammable matters.
Don’t expose it directly to sunlight and place it near the heat sources.
Keep out of reach of the children.
