Inverter indicates overload

[Solar Rookie]

I have a PTS 200S-24E inverter which is a 24VDC-240VAC, 2000W inverter. I have had it running for less than a week and had to turn it off to charge the batteries under consecutive cloudy days and it indicated that the battery was low.

Now that the batteries are charged (indicated by the regulator – steca 12/24V 20A), when the inverter is turned on, the LED indicator is RED the text next to it is ‘Overload’. We decided not to turn on anything on the output end and are troubleshooting on why the inverter is indicating ‘Overload’. There are no beeping sounds like it did when the batteries are low. The Voltage out of the battery is 25VDC and the manual indicates a range from 21.4 – 33V so I do not understand why the inverter is indicating an overload?

My solar system is located in Papua New Guinea (near the equator).

If there’s anyone with suggestions to fix the issue or has had similar issue and fixed it, I’d take any advice at all.

Where are you measuring the voltage at?

You need to measure the voltage at the input terminal screws on the inverter with it turned on with a load turned on taking power.

Thanks for the reply.

The voltage at the inverter terminals is 25V and have discovered it is not producing an output - checked this by turning on an appliance. Not sure if there is a fuse that's blown and am hoping any possible damage / fault is not permanent!

If you have good power in but no power out. Guess what?

grrrrr! It's been a journey getting started on this project! I'll see if I can get it replaced by the supplier. Would there is a fuse that's blown or something? I don't want to have to buy another inverter .

Just about all inverters have some sort of fuse or breaker. Does th einverter have GFCI receptacles? If so check them and see if they tripped. If so just push the reset button.

Thanks again Sunking for another reply.

The manual says it has an in-built GFCI and shuts the AC output when the leakage current is > 5mA but seems there are no reset buttons outside the casing. Might try opening the unit and checking the inside. The procedure to reset on the manual says to turn off, take the load out then turn on again.

This is more promising than I thought! I will update what I find.

Disconnect th epower, wait a minute, and retry.
