Reliable pure sinewave inverter replacement parts query

[fabieville]

I have a reliable 24v 3000watt 120vac pure sinewave inverter and  one of the diodes need replacements.  It is labeled D13 on the circuit board. Because it is so small and fractured i cannot read the value on it.
Is it possible you could tell me what diode to use or is it possible for me to just replace the 4 diodes that are in that section ( D2, D5, D12, D13) with regular barrel shape diodes? If yes what value diodes I should use for each of them? or basically i could use just 4 same small barrel diodes and which position is the correct way to place them in the circuit?
I upload some pictures of where on the board they are located and the model inverter that i have.

In the pictures they are located to the left side beside the brown filter caps. You can zoom in to get a better view of them and the 4 mosfets that are located there too.

Make? Model? A pic isn't going to tell us what diode you need, there are literally millions of them that look like that!

The brand is "Reliable".  It's a generic Chinese brand.

Can you get a close-up picture?
The text on the diode looks like it can be read, but a sharp close-up photo is necessary.
Either you or I can look up the part number here:

I uploaded the photos. So can someone please help me out. I would greatly appreciate the help.

Like Sparweb says, we need better pictures of the damaged components.

i got a reply from reliable company saying that the replacement is 1N4148. I am wondering if i can replace all 4 diodes in that section with the same #? what do u think?

[Mary B]

1N4148 is a common rectifier diode, https://www.digikey.com/product-detail/en/on-semiconductor/1N4148TR/1N4148FSCT-ND/9356376 10 cent part LOL Digikey is a greta electronics part supplier, I use them a LOT

[fabieville]

can i replace it with 1N4007 or all 4 of them on that section with 1N4007?
the ones on the board is the very small solid state ones and the 1n4007 that i have is the regular small barrel type.

[DamonHD]

1N4148 is a fast(ish) switching/signal diode.  1N4007 is a power diode and may not switch fast enough to be safe in that circuit.

1N4148 is a small signal diode, not a rectifier diode. 75v max reverse voltage, 150mA forward current.

Using a 1N4007 MAY work but the junction capacitance will be much higher - whether that matter depends entirely on what the circuit is doing.

A quick online search prices them at $0.70 per 100 - i.e. less than 1c each.

I notice that when i turn on the inverter, the driver board inside the inverter has a red light flashing instead of a steady red light which would suggest that something is wrong i presume.

I see the input voltage on the inverter display but there is no output voltage display and when i test the output i am getting around 18vac instead of 120vac.

Please tell me what could be the issue(s) and which parts would need to be replaced.
I anxiously await your feedback.

.... It is labeled D13 on the circuit board. Because it is so small and fractured i cannot read the value on it.
.....

If it fractured due to electrical fault, there could be other parts that are damaged. Troubleshooting would be difficult without the schematic and I doubt if the manufacturer will give it to you. Not sure if it will help but we can attempt to reverse a portion of the schematic.  Can you post close-up pictures of the top and bottom of the area where D13 is to find out if reversing is possible?

The IRFP4368 fets inside are damage. Can you tell me a replacement or equivalent fets that can replace them.
I am trying to source some local fets in Jamaica that can work.

[fabieville]

would any of these be equivalent to use?
