At first i wasn't sure what you were referring to but let me confirm you were meaning the breaker inline from battery to inverter?
It is a resetting breaker and i suppose that could've been what was tripping but i don't understand why it would. Could you explain your thoughts?
In the original post the complaint was that something was tripping and resetting not just making the coffee. If the tripping and resetting didn't happen and the system just made the coffee then it would be doing what you want and not be broken. If there is a breaker rather than a fuse between the battery and the inverter that might be what is tripping and resetting. A voltmeter applied to the input to the inverter could confirm that as the source of the tripping and resetting.
Why would it trip? If it is a 60 amp breaker feeding 60 amps to the inverter it would trip because it is supposed to so that the wire doesn't overheat. A 60 amp breaker can, depending on the part, pass 120 amps for several seconds or it can trip at less than 60 after a minute.
Without diagnosis you can change parts until you happen to change the right part.
If you need a bigger breaker to make it not trip then you probably need a fatter wire. If the wire is too long and too skinny the inverter will, lacking volts, take more amps to get the watts it needs. A bigger breaker still has the disadvantage of being a breaker. They have more voltage drop than fuses.
My suggestion is to put a voltmeter on the inverter plus and minus inputs and start a brew cycle. When it trips see what the voltage input to the inverter is. If it is zero the culprit is between the battery and the inverter.
Next connect the voltmeter to the battery plus terminal and the inverter plus terminal. If they are farther apart than the test leads can reach use any scrap of insulated wire to extend the test lead. It doesn't need to be fat at all, #22 will be fine. Start or restart a brew cycle. If there is more than .125 volts, 1/8 volt, drop on that wire from the battery to the inverter it needs to be fixed.
Repeat the process measuring the voltage between the battery minus and the inverter minus terminal.
If the two voltages add up, for example, to a half volt that is not good. When the battery puts out 12 volts the inverter only gets 11.5. At some point the inverter shuts off when the input is too low. The inverter doesn't know or care why the voltage is too low. The battery might not be too low
You have several suggestions of what to replace to fix the problem. Since you have not yet identified what is not working correctly, do that first. If the problem is between the battery and the inverter neither a new battery nor a new inverter will fix the problem.
Most people on these forums have a volt meter or can borrow one. That is adequate to diagnose this problem. If you have access to a DC clamp on amp meter you could measure the amps being used by the inverter and you could compare that to the rating of the breaker. That would only tell you that you are using a current more or less than the rating of the breaker. The voltmeter will tell you if your breaker tripped. It may or may not perform according to its rating.
