FX2012MT AC POwer error led

Postby jfguay2 on Tue Apr 23, 2019 12:00 pm

Hello,

Recently, I have started experimenting an issue where my inverter will come on once hooked to the battery bank, as usual, but when I plug in shore power, the ac in led comes on, but once the relay tries to connect, the error led comes on for a second and then both ac in led and the error led go off. This goes on and on forever. This started happening after I took my battery bank off the motorhome, and put in back in , reconnecting everything. I am certain the polarity is fine, so I am wondering whether I burned something in the inverter that is preventing in to properly activate the internal relay to pass on the 120 v shore power to the motor home.

Any idea before I dissassemble the beast?

Just my two cents, but relays are magnetic switches in many cases and can easily stop working properly without notice. They are subject to wearing out. Hopefully you eliminated this aspect already.

Have you looked in the system logs to see what error(s) displays?

No I haven't yet, as I still need to unmount the beast from within the storage bay, so that I can open it up. Where could I find a wiring diagram of the thing?

I suppose I have to use the Mate to get that right? I am pretty certain I look at all I can access through the Mate2 that I have connected to the inverter, but could not see anything. Under which menu should I look? For some reason, I feel as though I don't have access to the complete array of settings of the FM2012MT through the mate2. For instance, I can't change the charging settings, and don't have access to a bunch of other settings, don't know why.

Any help or insight would be greatly appreciated.

Regards,

JF

Before removing the inverter I suggest you verify the AC voltage at the inverter input. Check the Mate2 to see what it says for AC input voltage or use an external meter. Watch what happens as the inverter tries to connect to the AC source.

It sounds like you might have a Mate2M instead of a normal Mate2. Check out this manual for guidance http://www.outbackpower.com/downloads/documents/system_management/mate/mate2m_installation_usermanual.pdf

I will do that tonight. Thanks for the information on the fact its a MATE2M. By reading the manual, I came across how to access the advanced menu, which is hidden!! Never knew that and never could figure it out.

thanks a bunch, will report back tomorrow with my findings.

Ok well things are getting worse, as as soon as I plug the inverter on batteries, the fan comes on but I get no led on anymore, nothing at all, and nothing either through the mate2m.

What could it be at this point...?

I left the inverter connected all night and this morning, I had a power on green led light on!! I can now access the Mate2M. Will try and see if any errors are coming up. Still can't get the power in to trigger the passthrough relay. From a quick look this morning, before I went to work, my low voltage (ac) cut off is showing at 0, and same with the high voltage (0), and can't seem to change the values either. Obviously, something is wrong ...
