inverter shut off

[ChaseTX]

Just curious if any one has run into any issues with their inverter shutting off and right back on while opening slides out? The only thing I i can diagnose it down to is the hydraulic fluid being very thick while cold. Which is straining to much causing it to shut off as maybe a safety. Maybe this will clear up when its warm. This is with out Shor Power connected, when I hook shore power up there are no issues.

Check the circuit breaker to the pump motor. Keystone installed underrated breakers. There is plenty of discussion here including pictures.

Inverter or converter? They do the opposite function but are often confused for the other.

If its your converter briefly shutting down when not on shore power, its likely a low voltage condition from batteries or from the battery circuit. (Loose connection, bad ground, DC Breaker/fuse, battery disconnect switch, etc...)

ChaseTX - do a search for “80 amp” and dozens of threads with pics, directions and testimonials will pop up. This will cure your issue.

Edit: are your slideouts hydraulic or electric? I know the 80 amp circuit breaker fixes the issue for hydraulic slideouts - not sure if they are electric. Someone here will know.

I appreciate the quick response, I am trying to fix the oddball end items while camping is kinda restricted right now. I will be checking this out today.

Ha, you are correct it is the converter, I knew this forum would be worth it. I have had issues with the connections since i purchased it. I have rewired and I do believe I will be upgrading my batteries as well to a couple of 6v batteries. I do not think the 1 battery it comes with is enough for the hydraulic system, even at full charge. I also will be looking at that breaker as well, better to fix that now than wait till later.

If you have a good battery it will work the hydraulics fine. I use one battery and have no problems. If the breaker is 40 amp no amount of batteries will help.

Do not understand why you say your converter is shutting off. Maybe it is just me. But do you mean the slides are stopping and then restarting? If so, that is not the converter shutting off. It is the auto reset circuit breaker for the hydraulic pump tripping and resetting as referred to in the posts above. That is an age old problem for many of us in the past and has been solved by replacing the 50 amp breaker with an 80 amp breaker.

Since you do not have the problem when connected to shore power, it may be a case of a weak battery. And since the converter is only operating when on shore power, it may be that the converter is supplying just enough extra power supporting the battery that the slides work ok. A weak battery, and hence a low voltage, can cause a motor to draw more current than it normally would with correct voltage.

Note that you will have two or three of the auto reset circuit breakers. So you must be sure which one is for your pump so that you replace the correct one.

I appreciate the reply and the further explanation over the Why. After hearing the many things it could be and my subject line of the inverter, I feel that it is the breaker on the hydraulics. My battery is fully charged and I know I have good connection. Seeing that the hydraulic pump is on a 12 v system, the converter is not going to matter since im not plugged in to shore power to convert to 12VDC. The inverter is out of play since it is not inverting anything on that electrical side. It would make since its the breaker. I appreciate you all walking me through this. That could have been a pricy mistake. I will let you all know the outcome when replaced, I do have the smaller breaker.

From Amazon. I agree with the above listing as the famous breaker and/or low voltage. Had the same issue and ran into one more item after checking battery for full charge and replacing the breaker. In my case, it was also a loose post on the polarity reversing solenoid. So just double check all connections. See pics

Thank you, that made things real easy. I just purchased it.

No sweat. I just recently went through it and everyone here assisted me. The least I could do is pay it forward. Stay healthy!!
