Inside the ones today there are one or two diodes. Most likely you have blown one or both safety diodes. It is an easy fix if you know how to use a soldering iron. Open it up an see or ask a ham or electronics person.

no idea as to the wattage used in your house as it varies with the equipment you have to go around and add all of the wattages in use your self ---lights each, fridge , freezer , stove , fans each , air conditioners each, toaster , microwave etc and add then all up that will show the total wattage in use for the house then you can put that in your supply meter

The first diode on the board? No way can we tell what the first one is however, if it is the one that is on the input connection for the power then it is probably 1N5402

What is the exact question?

you have to know the wattage of the pump motor to get that answer if the wattage of the motor is 750 watts then --no-- as the continuous current draw is more than the 500 watt continuous allowed from the inverter when an electric motor starts there is always a high current draw ( surge ) and that is why there is a surge rating for the inverter but that surge is for a second or less so the components of the inverter will handle it but they will over heat and fail if run for longer above the 500 watt rating it best if the pump rating is around 85% of the inverter rating so if it is more , then get a bigger inverter

Hi there ! please get some to open your inverter and check for short in the transformer coiling .and also check the fuse . good luck

Bad battery, bad connections or bad battery cables? Battery cables are too long and using thin wire?, The cure you need to use thicker copper wires or add more wires in parallel?

Have you checked the voltage going to the inverter? Sounds like you may have exceeded the load that he inverter can handle but not enough information to confirm that from this end. You mention "plugged into my van battery", possibly you have this plugged into your Cigar Lighter? Mega fuses are usually really high amperage fuses, much more than the inverter could blow and save the inverter. The fuse should be matched to the load and about 50% higher. If the device is rated at 10 amps, a 15 amp fuse will provide protection where a mega with 500 amps will act like no fuse at all to the inverter.

LS = Low Speed. The inverter is enabled with a signal on ST but it missing the speed and direction command/signal. Speed and direction can come from many different sources (digital, analog and or communications). Check your wiring diagram to ensure that you have the proper signals.

I've had a couple of inverters do that. In both cases, one or more of the switching transistors, or scr's, went bad. If they short, the unit will show overload. If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_29ad5d1dd86564b0

Check your fuse. If it's a clear fuse and you can easily see it burnt or good this will tell you if it needs replacing. If it's a ceramic fuse you can use a multi meter to check for continuity.

H.I.M. modules are usually used to access parameters as well as PC software. If it just has and LED display then you might do it there. What brand and model is it? I will gladly help find documentation.

have a technician load test the batteries and replace if necessary

Is that red light flashing or continous lighting? You do not need 3 phase input for that model. Do you have the input wiring diagram? If the red light is flashing maybe the emergency stop input is active. If the red light is on continously then it maybe in stop mode or torque limit, ask electrician to check the wiring.

Make & Model? A troubleshooting Hint: Remove & unplug everything from the AC outlet(s), still have the OLP error code? Note: Some 3000W Inverters have two inverter circuits operating in parallel, if one circuit blows its internal fuses maybe its only work on one circuit ? Usually there are a number of 25A car fuse (Qty 8) in parallel for each inverter circuit. Unless it was overloaded momentarily there should be no reason for the fuses to blow under normal working conditions. That means highly likely they may have blown due to circuit fault.

most inverters will not work unless there is grid voltage ( utility power supply) to turn the inverter on if it is saying grid fault that indicates a power line in problem and no external power supply contact your power company as there could be a black out in your area or maintenance work being done if not the case call an electrician

Hello Adam Colson, Welcome. Thank you for your entry... I took the liberty of moving it (?) from refrigerator/freezers... because it only says "GFI" . If your entry is wondering if your True Sine Wave Power INVERTER ... Is about compatibility with Ground Fault Interrupters (GFI/GFCI) the answer is MOST LIKELY NOT compatible. Predominant reason could be the world still uses DEFROST TIMERS... which have only 4 terminals and 5 power applications (clock motor: one of which usually ends on an internally shown ground). In no way dangerous... but certainly an OPERATIONAL trigger for your GFI. Hope this helps... ELSE comment me back (but I won't EVER tell you to disable a GFI: They are vastly superior to older safety systems). I'll be here again tomorrow (unless it rains)
