The AGM won't hold that high of a voltage for long as it would be all surface charge. It will drop to about 12.8v very quickly.
What I'm thinking is AGM could be providing power to the BMS instead of Lithium, therefore Lithium voltage stays intact. When Ecotrek is connected to the load side, it has no choice but to power itself including BMS.

Is the inverter on?

Hard to tell, I think. We have all assumed that the parasitic from the modules when turned on was from the connecting relays, so whenever it was on active they would be connected to as far as the coach power switch. How new is your unit?

No inverter was off as well. When battery disconnect is OFF, this all doesn't matter since no power connected to the load side.
When I initially turn Ecotrek module on, it's disconnected from the load side by default. I have to press "Reset" button for it go online. In both cases I hear relays clicking but with different sounds.

The unit is only couple weeks old.

The other thing I noticed is when Ecotrek is on but disconnected from the coach, the solar charging is very fast as it does not have to go against parasitic load. Also, I noticed that voltage showing up in this case is 14.10 volts or even higher, while when Ecotrek is connected to the load side, it rarely goes above 13.5.

I don't think ARV is motivated to just sell Delco alternators equipped with their custom torque converter. Without that feature, a basic Delco would be considerably noisier and I wonder if it could impact engine main bearings. Beyond that, for an aftermarket installation, the bottom line cost of materials and labor could cost upwards of $3,000 which begs entertaining whether it's worth the return on the investment if you're not insistent on running an AC off grid all night.

There must be something here as the whole purpose of AGM I believe is to provide power to BMS and wake up a dead Lithium module should it go offline due to low voltage, etc.

Speaking about alternators, I noticed that on my Agile the second alternator is located very low, just behind the front bumper. On Zions built on Promaster chassis the location is even lower. It probably has to do with cooling. At the same time it's exposed to the elements or debris which is not good I believe. I already hit a crow on my first trip but the alternator held well

Sorry I haven't posted more today, it's just that I was busy driving my new RoadTrek Adventurous

Third Balmar fixed the issue and they showed me before I signed the paperwork, gave me a check for my lodging costs, and I split. I'm very happy in the end.

GU is charging them up driving too, so I'm at a campground on a lake now doing some testing after a couple hours of driving.

I'll be particularly interested in testing out the air conditioning because I suspect it's not working properly at high temp but jury is still out. Then testing out the dumping stuff. Then the Alde which I hear has many issues for many folks. Fingers crossed I'm not one of them.

Good to be an official Class B guy Thanks to all you old heads for the help along the way. Much appreciated!
