Hi guys 

 

I have a problem with my 5Kva inverter which having a 09 error bus soft start failed

I tried to disconnect the battery cable when i had switched off the inverter then one of my leads had a contact with a metal surface and spark came out ...but i have opened the inverter  and i dont cee  anything defective ..

May you please help

What you should be looking for are the battery-side MOSFETS. Note how they are recessed under some heatsink fins:

Those heatsinks are jammed against the right hand end of the case (in the photo below; see the orange rectangle; ignore the yellow text and lines):

So you won't see the MOSFETs unless you use a dentist mirror, or possibly you can see them by looking through the ventilation holes on that side of the case.

There is a small chance that the damage is to the IGBTs, which are under the fins of the other heatsink at the left of the above photo. Note that the damage may not be as obvious as in the photo above (though it certainly can be); I've seen IGBTs whose only visible flaw was a hairline crack in the package. So inspect carefully before you decide that there's nothing wrong with the inverter hardware.

If your inverter-charger model is the older type with the black heatsink on top, the Solar Charge Controller electronics will be in a different place, but the MOSFET and IGBT locations are the same.

Has anyone the schematics of this inverter-charger?

My inverter do not show anything on the display, but the 2 fans are on.

There are partial schematic traces for the PIP-4048MS model here. Most models are broadly similar with the exception of the Solar Charge Controller in some models.

That sounds like the connector to the display is loose, or in the wrong place. Any LEDs on? Depending on the model, they may use a different connector.

Hello 

Just wondering if anyone knows why a MPP LV5048 Split Phase 120V/240V output 5kW 48V would have a error 09. Replaced the motherboard with new one and still have problems. 

 

Thanks!

Still have the same problem, i.e. fault code 09?

I assume that this is a 145V max PV model, correct?

Does this model have two main boards? With the two DC to AC converters? It seems likely that if one blows up, the other would as well. 

Does any one have the schematic diagram of the inverter? If yes, please share it will be helpful in troubleshooting.

We returned the inverter within seven months of purchase with this error and the supplier yelled at me that the inverter was overload!!! We only used 0.3kw with only a energy saving refridgerator and a deepfeezer connected to the solar. How or where do i go for complaint

Are there alternatives to the UC3845A from Ti. The delivery times are currently at Mouser at 09-2023. Can you take something from STM, e.g. UC3845BD1 or someone else? (component U16 on the boards)
