I hate to ask, but I my searches were unsuccessful .... I saw a thread where someone was talking about the Powerpro only heating the cells while charging... anyone know where I can find the thread?

I am from Germany. Don't mean to come off rude
There is a new update that starts the heater 32f or lower and the heaters cut off at 35f and if the batteries are 10% SOC or lower

great, thanks for the update on the update ;-)

You can also stack the rack batteries to the ceiling. You can't really with these. So space efficiency is debatable. You can go wide/horizontal, but that's more space.
I take it this requires a firmware update via the rj to USB cable?

What about in combination with the eg4 6000xp. I have no need for the large expensive inverter

Hopefully we can get that 9540 with the 6000xp as well, we are off grid and don't need the expensive 18k
In all for this & recently bought 1 PowerPro & plan on buying 2 more.
That said it's kinda what I did for my 6 LifePower4's. I wired an additional outlet in my insulated solar utility room where the inverter & batteries are. I then plugged a $15 Thermocube plug (powers on 35⁰-45⁰F) & then put a $24 1,500W ceramic heater plugged in to that. We also have a wireless temp monitor in that room so we always know how warm or cold it is in there. There has been no problem keeping it warm in that room. The only exception was when something accidentally got put in front of the heater. The safety on it was triggered when it got hot (thankfully) & then had to turn it on fully the next morning for a little while... no big deal.

What's strange to me is a lot of these battery heater units turn on just above freezing like 35-40F. Where they shouldnt be given full charging current. Seems like ideally you'd keep them at 70F or something, then there's no drama for them to receive the full output of your panels in the morning
It's really not a big deal, driveline not a drama. The batteries have no problem discharging below 32⁰F... but the BMS will not allow them to charge. I honestly think between the insulation, fridge/ freezer & the inverter that the heater rarely comes on. It's mainly just a backup.
That said, when the batteries do get cold it seems to takes a bit longer to warm them up as I think they act like a cold sink, especially the ones closest to the floor. This is why I put the heater on the floor for the heat to rise.

Can someone please show a display of how you would connect 5 powerpro wallmounts with 18kpv including external busbars?
I don't have a pic now, I will upload some tonight. I dont' have the 18kpv, but I do have 5 powerpro's connected to dual Sol-ark 12k's. I would imagine that all the way from the busbars to the batteries would be the same.
I mounted them to my external wall. Then I went through the back of each of the attached conduit boxes and through the garage wall through 2.5" pvc conduit. From the wall I went down into the top of a 10" wireway that holds all of my wiring.
Inside the wireway I used these bus bars (they come as a kit of 2 black/red) and spaced them about 2 feet apart:
I then used new 2/0 flexible battery cable as conductors as the stock ones are not long enough. One side I attached the specific ends that the powerpro batteries use as a connector and I had to put crimped ring connectors on the opposite ends of the wire.
I made equal length runs from each of the batteries through the conduit and connected to these bus bars. The conductors from the batteries that are the furthest away will have nice clean runs of wire while those batteries that are closer to the bus bar will have extra lengths of wire that you have to deal with in the wireway.
For each of the positive conductors I have a class T fuse between the bus bar and each of the batteries. I took each full length of red conductor and cut it into a short length with ring connectors (bus bar to fuse) and a longer length of red conductor with a ring connector on one end and the powerpro connector on the other (fuse to battery terminal).
I also have another fortress evault 18.5 connected to the bus bar as well. All the powerpros charge/discharge at the same rate with the fortress at a slightly different rate, but not enough to be concerned with. I attribute this to a different battery composition.
I do not use a battery BMS. I finally got all the settings lined out on my dual inverters and the system works great!

Awesome thanks a lot id love to see a Pic if you get a chance I have 3 currently working perfect now with communication and monitor app being accurate but curious if adding 2 more would be as easy as it seems just hooking them on each end of the outside 2 
I was thinking of using external busbars like you mention but was curious if the inverters should connect to the busbars or outside batteries or the center haha

Solar Joules are catch and release
Yes, but note this uses the RS232 firmware update cable not the RS485 firmware update cable. You’ll need one of each to do them all.
