20 Most Recent Inverter Vector 400-Watt Power - Page 5 Questions & Answers

The battery is likely shot. Try replacing it.

It sounds to me that the inverter is working fine, just undersized. Motors consume a LOT of power when they start. A fridge compressor could draw as much as 800W when it first starts up.

My quess is it is broken!

It depends on what you are using to measure the voltage. Cheap meters can do this. You need a true RMS meter to read these properly. Most inverters use Modified Sine Wave technology which mimics a sine wave poorly and cheap meters do not respond well to the waveform. There is likely nothing wrong with the inverter.

Remove any load that you might have on the inverter. Turn the inverter on and if this still happens, then the inverter needs repair/replacement. Also watch the battery voltage. If it drops more than 0.2 volts, then the batteries are likely discharged or defective.

he battery might be undercharged or defective.

heck the fuses, breakers, battery connections, and battery.

Check the fuses. Check the battery connections. Check the batteries.

Just replace the thing.

Could it be that your batteries have a problem? If they are constantly on charge, they will dry out, the plates might warp, etc. I would disconnect the batteries and put a headlamp or something like that across them and see how long they can run the load. Most headlights draw 5 amps per filament. A good battery should run the light for at least 10 hours, all depending on what their amp hour rating is. If the amp hour rating is 100, then the lamps should run for at least 15 hours without loosing intensity. If they don't then get the battery tested/replaced.

It basically means that there is no load on the inverter. If you an an AC load to it, you should see this increase.

The battery has failed. Replace it.

Remove the load and see if the noise, etc, disappears. If it does, then gradually apply loads. If the fault returns immediately, the inverter has an internal fault. If it fails as you apply loads, than you have exceeded the capacity of the inverter, so remove a load.

I have no idea what the cost would be to repair it, but you are probably best to just replace the inverter. Replacement parts, plus the labour charges to repair it would be more than the cost of a new inverter.

Replace the relays.

Yes, it probably is a MotoMaster 3000W inverter. Whats your question???

If the inverter is intended for 6 volt batteries, and I doubt it, then yes. However, it is common to connect two six volt batteries in series to get 12V, which most RV inverters use. I have four 6 volt, series parallel connected batteries in my home providing 830 AH to run the house during the peak periods of the day. I have never had a problem with this set up.

It sounds like you have a blown fuse or an open breaker on the inverter. Another possibility is that the batteries are not charged sufficiently, or are not connected. Some have a disconnect switch associated with them, and others have a disconnect plug. You might want to check that out.

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.

Hi Larry, I have no idea what the power consumption of your particular fridge is, but mine is very large and consumes 350KWH per year. That's a KW per day. My quasi solar system seems to handle it just fine. You should be able to find the yearly power consumption of your fridge from the manual, or from Vissani's website.
