Jacky,

If you are seeing what Mark says is oil (maybe water also) he is probably correct.

I believe you have the Haldex dryer and like mine and I change my element every 2 years and see no oily residue near the purge, nor do I ever see moisture or oil from the wet tank.

If you can verify you are seeing oil you may have a compressor passing oil and given the recent service interval it would be worth checking. Oil passes every compressor, but not to the extent that you would see it in such a short period of time.

“Freak out” and “Act Crazy” are not technical terms.

I will assume this does not relate to the 24V battery charger for the chassis batteries. Everything I say below relates to inverters and house batteries.

First, try to understand both inverters are charging the same batteries at the same time. One becomes primary but the second is still working as a charger in the background. Typically when the batteries have a 100% charge the inverters go into float.

If something is wrong it could be an internal inverter failure and charging current or voltage is no longer regulated by the inverter, or it could be external. If it is external such as a corroded ground the inverter does not “see” the correct battery voltage and instead ramps up voltage because it reads the voltage as a depleted battery.

For us to go beyond that you have to provide a lot more information, such as inverter brand and model, actual battery voltage, charging current setting, age of batteries, etc. Apart from issues previously covered it is not beyond the realm of possibility to have a failed or failing battery creating issues. But without good information everything we say here is pure guesswork.

Just a note………..one of the most overlooked issues is bad batteries. A lot of guys convinced themselves their inverters had gone bad, replaced them with new ones only to find one battery in the set was bad and it was presenting issues folks believed were inverter problems. So before you go much further you may want to consider separating the batteries after they have gone to float and testing each one.
