When installing the inverter, make sure that there is enough space around the inverter to ensure adequate installation and
cooling space, as shown in Figure 3-2.
4. OPENING THE DEVICE
Non-professional personnel must not open the inverter as there is high voltage inside. Before opening the device, please remove
cables of both DC and AC sides, turn on the switch and leave the inverter alone for 1 hour.
5. CONNECTION
1. Battery connection
The two DC-input connectors of the inverter are color-coded:
- The red terminal for the positive pole (+) and the black terminal for the negative pole (-).
- Use the supplied cable from the manufacturer or at least those with the same or larger cross-section.
- Keep these connections as short as possible, it will flow considerable current depending on power extraction!
- The connections between power source (battery) and inverter cable terminals must be securely mounted.
Note: The error will be reversed, which will cause the inverter to malfunction.
Before installation, confirm that the positive and negative electrode of the battery and the positive and negative connection of
the inverter are correct.
If the reverse cause inverter failure,
Remove the upper cover of the inverter, find the fuse on the motherboard, please replace the spare fuse in the accessory.
2. Load connection
The load power should not exceed the rated power of the inverter.
Set the switch to the "OFF" position when connecting the inverter to the power source. The energy source may be a battery or
other stable DC power supply.
It must be ensured that the DC voltage of the power source is matched to the rated DC voltage of the inverter. Higher voltages can
cause fire and damage the inverter.
The battery must be able to deliver necessary amperage according to the power of the inverter and load. For example, for a 24v
inverter to drive 1000W resistive load, the battery should be able to provide more than 45 amps! (on a 12V inverter it will be >90
amps!)
Please do not connect the AC output side to other power source (i.e. electric supply) as this is not a grid interactive inverter.
Please read the manual carefully and install the inverter properly. If you have questions, please contact our service team. It may
cause damage to the inverter or cause injury if you do not act in accordance with the instructions from the manual.

Therefore, when any one controls the inverter, the other switch must keep the "OFF" state.
According to different models, we have two models of remote control (ED-RC, ET-RC). However, it is not possible to replace each
other.
ED-RC remote controller
1. ON/OFF switch
2. Status light: If it is green, it means the inverter is on. If it is off, then the inverter is off.
3. Low input voltage indicator light: If the DC input voltage of the inverter is too low, it will be yellow
4. Battery power indicator light:
If DC voltage ≥12.5V, 4 LED lights will be green
If 12V≤DC voltage≤12.5V, 3 LED lamps will be green
If 10.8V≤DC voltage≤12V, 2 LED lamps will be green
If 10V≤DC voltage≤10.8V only 1 LED lamp will be green
Note: If your inverter is 24v, please multiply the above DC input voltage by 2.
About ED-RC remote cable
ED-RC remote cable is 2M or 4M long standard RJ45 network cable, it is easy for you to extend the length of it. When working,
the voltage drop through this2M cable is about 0.02V, you can ignore it. If it is a 10M long cable, the voltage drop will be about
0.1V. If you use very long remote cable, please note that the battery power indicator light maybe not correct.
Note: If the remote controller can’t work properly, please try to replace the remote cable first.

8. HOW TO SELECT THE PROPER INVERTER YOU NEED?
Dependent of the devices you want to operate, you must pay attention in the wattage of each device and calculate the total watts.
We recommend you to buy an inverter higher than the power you think you need – good practice is around 30% - 50% more.
For example:
We recommend you to buy the power inverter 1500w. Sometimes devices like a motor, it need more power at startup (peak power)
although after the motor is running use continuous power. This is important to consider. For example, an air conditioner,
refrigerator may need startup-power from 3 to 7 times the continuous power. The best procedure is to find out about the current
requirement of the device to be connected to the inverter. Normally this information is in the device specifications.
Example:
If you have a refrigerator with a continuous load of 0.8 amps and a startup load of 8 amps:
0.8 amps x 230 volts = 184 watts continuous
8 amps x 230 volts = 1840 watts continuous
In this case you should use an inverter with 2000W.
9. ATTENTION ABOUT MODIFIED SINE WAVE INVERTER
The output waveform of modified sine wave inverter is not pure sine wave. It is different from the waveform of our home grid
system. If you use it to run inductive loads, it is possible that the inverter can’t work properly, or its performance is less than
expected. This may also bring more noise.
1. If using a modified sine wave inverter, devices like induction cooker, coffee machine with pump or compressor inside,
medical equipment can’t work properly.
2.
3. Motor, pump, electric saw, and devices with compressor, when starting, they may require 3-7 times power as their rated
power. It is not recommended to use a modified sine wave inverter to run these devices. If a modified sine wave inverter is
used, maybe these devices can’t start and this will also shorten the inverter’s life.
4.
5. Fan, fluorescent lamp (with Ballast), vacuum cleaner, electrical tools, it is not recommended to use a modified sine wave
inverter for a long time, these devices will bring more noise with modified sine wave inverter. If using for a long time, this
will also shorten the inverter’s life.
10. HOW TO CHOOSE THE PROPER CABLE?
Inverters should be attached directly to the battery. The wire size depends on the distance between the battery and inverter.
The following is a reference to the cable size of the battery recommended by the DC12V system inverter. (DC24V system inverter

11. TYPES OF BATTERIES
You can calculate that the storage battery’s use-time by this formula:

COPYRIGHT©EDECOA, ALL RIGHT RESERVED, PI-EU-Rev 2.6----English
10 /14
푈푠푖푛푔푇푖푚푒 퐻표푢푟푠 = 퐵푎푡푡푒푟푦퐶푎푝푎푏푖푙푖푡푦 퐴퐻
푙표푎푑 푝표푤푒푟(푊) 0.85/퐵푎푡푡푒푟푦 voltage(V)
Attention:
The use time of storage battery is determined by the quality and the condition and lifetime of the storage battery!
Attention:
If batteries of the same size are connected in parallel, the time is multiplied by the number of parallel batteries. For example, four
12V 60AH batteries are connected in parallel, and 500W of load can be used continuously for 1 h 12 min*4=4 h 48 min
The above is the time that can be used when the new battery is fully charged. If it is an old battery, use it for more than half a
year and multiply it by 0.8. The battery has been used for more than one year. It needs to multiply the usage time by 0.5. For
example, a 12V 100A battery has been used for half a year. If a 1000W load is used, it can be used continuously for 1h*0.8=48
min.
Tip: Use the inverter in your car. Engine start batteries should not be discharged below 90% charged state, and marine deep cycle
batteries should not be discharged below 50% charged state. Doing so will shorten the life of the battery based on most battery
manufacturers recommendations.
Note: If you intend to use power tools for commercial use, or any load of 200W for more than 1 hour regularly (between
battery recharging) we recommend installing an auxiliary battery to provide power to the inverter. This battery should be a
deep auxiliary battery should be connected to the alternator through an isolator module to prevent the inverter from
discharging the engine start battery when the engine is off.

18. IMPROPERUSE OF POWER INVERTER
1. Reverse polarity: For the models which have reverse polarity protection, inverter's fuse will blow out to protect the other
part inside the inverter when the inverter is connected reversed. It is possible to damage the part of the positive and negative
terminals due to high current after a short circuit. It will not affect the normal use after changing the fuse. For the model
which is not equipped with reverse polarity protection, it is possible that the electrolytic capacitor and the Mosfet will burn
out. When this occurs, a crack sound can be heard and smoke will be seen coming out.
2. When the input voltage exceeds the allowable voltage range of the inverter, the electrolytic capacitor inside the inverter
will burn out. In this case, a crack sound can be heard and smoke will be seen coming out.
3. Heavy overload. The overload protection power of the inverter is 10% higher than the rated Watts, mainly used to start
some appliances which require high start current. It doesn't support a long-term use. If customer uses the inverter for long
period of overload, it may cause aging of electronic parts and rapid increase of machine temperature. In more serious cases,
the electrolytic capacitor inside the inverter will burn out. If so, a crack sound can be heard and smoke will be seen coming
out.
4. The power inverter is used outdoor during rainy days or when water gets into the inverter. Because the inverter is not
waterproof, water entering any electronic part will cause short circuit and corrosion of such electronic parts. Failure to dry
after water entry will cause the electronic components to burn. When this occurs, a crack sound will be heard and smoke
will be seen.
5. The inverter output socket or terminal can only be connected to the appliance with the matching voltage. If the customer
connects the 110-120V appliance to the 230V inverter outlet, it may cause the appliance to burn out.
6. The AC output can only be connected to the electrical appliances. If connected to grid or generator, it may burn electronic
components. When this happens, a crack sound will be heard and smoke will be seen.
Should any of above cases occur here is the proper operation: first turn the inverter off; then disconnect the battery cable;
finally disconnect the appliances when smoke dissipates. Please feel free to contact Customer Service for technical guide or
repair service. (When the part in the inverter burns out, a crack sound will always be heard and smoke seen. Please keep calm
and follow the step above. Attention: please don't use water to irrigate the inverter or it will cause more loss.
