My inverter shows overload with no load - Inverter Electronics - Others

It sounds like you are drawing too much power. Pull all the power from it and try again without ANY load on it. If it comes up in the overload condition, then the inverter has problems and needs to be looked at by a qualified tech.

internal problem
have it checked out by an accredited service repairer

Hi, here is the error codes that I could find for you, it seems you are overloading the inverter. That means you cannot connect a kettle or other heavy load to the output. See all error codes below, hoep this helps.

Problem: The AC load will not operate, error code shows on digital
display and alarm is sounding.
Error Possible Cause Solution
E01 Low voltage shutdown because battery is discharged.
Recharge battery. Shorten cables or use heavier cables.
E02 Over-voltage shutdown because of high input voltage.
Verify the charging system is properly regulated and the battery
is 12 V nominal.
E03 The AC product(s) connected are rated at more than the
inverter's continuous power rating; overload shutdown has
occurred. Use a product with a power rating within the inverter's continuous power rating (see Table 3).
E04 The inverter has overheated due to poor ventilation.
Overheating shutdown has occurred.Turn inverter off and allow to cool for 15 minutes. Clear blocked fan or remove objects covering unit. Move the inverter to a cooler place. Reduce load if continuous
operation is required.
E05 The AC products connected have a surge power that exceeds
the Digital Inverter's surge capability or the AC products connected are short-circuited and shutdown has occurred.The products exceed the inverter's surge capability. Use a product with a starting surge power within the Digital Inverter's capability.

According to the alarm code E58 is usually a washing machine with inverter and means problem with inverter board or motor or wiring between inverter-motor.

Could be:

E58 - Inverter is drawing too much current (> 4.5A).
Abnormal motor operation (overload).
Motor-inverter wiring faulty.
Motor faulty.
Inverter board faulty.

E57 - Inverter is drawing too much current (>15A)
Motor-inverter wiring faulty.
Inverter board faulty.
Motor faulty.

The battery may be new- but how much charge does it have? The inverter has a high and low battery warning.

If the inverter has no load upon it, it may see the battery potential as high. so if you put a load on it such as an incandescant lamp, in parallel to the inverter, and as an inverter load it should circumvent the warning. Then it is a matter of fine tuning the setup.

every thing is working fine, the battery shows 13.28volts, the Mosfets are good, cant understand still why the hell it shows overload, without connecting any load to it, give me a reasonable solution if any one can.

try putting a load of 1 ton, if it trips , the overload control for your inverter is bad

2000w means is out off rang load 2000w plus then alarm beep have running.

Maybe too much things connected to it or it can't handle what you plug into it

This internal fault code can mean so many things, but basically it more than likely has some internal parts that the smoke is no longer inside. They can be repaired however, email [email protected] to discuss further.
