The manual recommends ≥12in separation between batteries.

So you purposefully made the manual requirement harder than what was necessary just to appease some AHJs?
That seems dumb. The manual should be the actual requirements. If an AHJ says 2 ft and you see 6.75 inches in the manual, you have more room to argue for 12 inches.
In other words, you shouldn't pander to the AHJ authority escalation tactics. Put what the product will do in the manual.

Yeah, or 6 by using two Victron Energy Lynx. Three into one, three into the other, and each Lynx going to the 18.

I am curious what the maximum amount of batteries that can be used, and still maintain closed loop communication.

Thanks for that information
Has EG4 considered making a battery combiner box?
I want to see someone build out 860 kWh of storage lol
I wonder how the internal shunts would work in terms of calculating correct SOC in this case.
Say you pull 100A, it'd only be roughly 1.6A per battery if you had 64 in parallel.
But that's ~5.2kW, which is way above the average draw I'd imagine.
Say your average draw in your house is 500W, you'd have almost no current from each battery.
Can the shunt measure that?
Forum challenge: EG4 should send Will 64 batteries so he can test it out.

These wall mount batteries are getting more and more attractive as the prices drop.
I have a good sized shed with a real roof on it that I could easily mount 1-2 of these along with an inverter in. Has enough roof space on it for a few kW of panels. So not having the weatherproofing, but still having the heating elements is basically perfect for this application.

I'll do it, just need EG4 to donate 56 of the 64 batteries

Isn't one of the ID specifically reserved for firmware updates? I want to say it's "64", which is actually zero...

ID 64 would be used for firmware updates. However, it can still be used for general communication in this instance.

Not that I am aware of, but I will definitely bring this up.

That would be an interesting test for sure!
Good point on the latches
Yes inverter fans. Not battery
Yeah outdoor rating is pretty good for the price. Won't have to worry about mounting location

I will be astounded if the price doesn’t drop 10% in a year anyway, but I’m saving as much as $1K/month on my power bills, so the price difference disappears in the noise. #IWantMyInstantGratificationRightNow.

I really like that the connections have been moved to the top, and the width is a little smaller. My area is pretty cramped, so I really appreciate any extra room I can find. I'm curious that they left the heater in.
I'm glad that EG4 is paying close attention to code compliance. I spent months trying to find a setup that would pass local inspection. At least I won't have to worry about the EG4 products.
