That is an interesting design and kind of useless for running A/C in the night while you sleep - or should I say waking up every 40 minutes to keep the A/C working. But I imagine you can power up more than one EcoTrek module at a time and face the extra parasitic drain from the BMS.

So I ran all 8 ecotreks down until they shut off (which I believe is done by the BMS at 20% of charge). My plan was to then plug into shore power which I have done. But despite the shore power showing good on the cord, I'm getting no power in the coach. Inverter, voltage meter, individual batteries - nothing. So I started the engine to see if the G/U would provide juice but I'm still getting nothing.

Is there some trick after running the lithium down like this?

If the AGM is also dead, there may not be anything to activate the charging sources. Do they have any kind of connection button to get the main van power connected to the coach to get started?

I am guessing that you are the owner who Jim Hammill gave reset instructions to over on the Roadtreking Facebook group, yes?

Interesting thing is that I just happened to turn on one of the ecotreks I thought was dead because it didn't fire up the A/C and this time it fired it up nice and has been running for about fifteen minutes now. Maybe because it was hotter then the surge from the A/C was too much?

I've heard it's best to run two ecotrek modules when you use the A/C and perhaps that is the reason why. But it wasn't drained like I was thinking it was.
RT has two delivery methods. For really long haul distances, e.g. south Florida and the West Coast, they are trucked and they add in the whereabouts of $700 for transportation At 918, it was undoubtedly driven to the dealership by one of their drivers. Consequently, when you took delivery, you can't assume that the batteries were in a full SOC.

The AC has no problem running from a single battery. I ran the AC for about an hour before shutdown with a single battery. But the 210 has a smaller BTU than your coach, so I don't think you can squeak out much more than 40 minutes but it depends on ambient temperature and the AC temp setting.

Chasis battery is fine. It's just the ecotreks. Dealership will take a look this morning.

The odd thing is that yesterday when I arrived at the dealership and first saw the rig, one of their guys said they had it plugged into 30 amp but that after turning the ecotreks on they were not getting them on. But then after awhile they would pop on. The way he described it makes me think they were not fully charged even after the drive. Or there is just some kind of an issue with them waking up. Not sure. Need more testing.

I would have thought that regardless of the batteries, with the GU on there would be at least DC power in the coach. But that wasn't the case. Will know more after today.

So I left the rig last night and got a hotel. I left it with ecotreks 1-7 "on" even though not showing power and inverter on remote "on" even though no lights and no coach power and I left the rig plugged into 30amp power.

This morning when I arrived, battery 7 was showing online with the blue light. It was the only one. No inverter remote panel lights to include the shore power light. So I reset battery 7 and the inverter powered up and showed charging from shore power, the volt meter had a reading of 12.9 or so, and batteries 1-7 showed online with the blue light. Battery 8 had been left off. So I reset and turned on battery 8 but it's still not showing the blue light.

It seems a temp fix for now might be to just make sure I always have one fully charged ecotrek to make sure the inverter is converting shore power to charge up the batteries.

But questions I have... If all batteries are dead or offline due to BMS, and the inverter isn't powered, how does the power go from shore power to the inverter so that the inverter knows it needs to convert to charge the batteries? Or does it? It would appear in my particular situation it does not. I had expected that shore power would go to the inverter and it would be powered and convert automatically. I'm not sure if that is happening. Maybe it's happening very slowly and charging up a battery without showing the shore power connected light? I'm pretty sure the shore AC power can't charge a DC battery without it, so maybe that's what happened. OR maybe when it got cooler outside the #7 BMS decided the battery could operate and kicked it on? Not sure.

My other question is why idling the engine with the GU didn't supply DC power to the inverter and power the coach regardless of the state of the batteries.

Will do more testing today. At this point while typing battery #8 popped online and is now charging off shore power too.

Not the Chassis battery.

There is another AGM battery -- a house AGM battery that is used to control your ecotreks. If you ran the ectreks dead, the AGM will also be dead (not a good thing), you will need to recharge it first before you can wake up your ecotreks.

If you open the hood, you will see the house AGM on the right side of the engine bay.

The chassis AGM is under the driver's seat.

In order to get regulated 12v DC power in the coach you need to have at least one Ecotrek online. With no Ecotreks online the GU is not connected to the load side of the battery bank. The inverter will operate without any Ecotreks online when connected to shore power but the 12v D.C. is very unstable with no batteries connected to the charger circuit. The inverter needs to be on to pass shore power through to the coach.
