I have a line on 2x 10C batteries from someone around here. They claim (and I cannot verify) that the batteries are "brand new in box", from "an authorized enphase dealer", and come with "full warranty". They also claim to have sold multiple already (these apparently aren't just a couple they bought and never used).

I had my system installed last year by a local company here, and I've contacted them about installing these two, and they say they're not interested in installing any equipment that they didn't source themselves. Fair. They did say I'm not at risk of voiding any warranty or service agreement if I have someone else install them, except that if a problem turns up in the Combiner (I already have the 6, I should be ready-to-go), they'll "have to see" if it's related to a bad installation. Also fair; I'm relatively confident it's pretty much plug-and-play from the Combiner point-of-view, and once all the hardware is in place, I can do the training and manage the system changes myself, I assume.

Now, the first question I have is, if I drop $5k on these two batteries, are they likely to be (a) fake, (b) defective, (c) stolen, or otherwise just a really bad plan? AFAICT, they're less than half the price they should be.

The second question is, from an electrical install point-of-view, can I have any ol' electrician mount them on a(n interior) wall and do the through-wall wiring (the combiner is on the outside of the wall I'd mount them on)? Simple as running about 10" of conduit and installing a couple breakers?

In Enlighten, WiFi says "not available", but it is indeed connected to WiFi (I run Unifi gear, it's definitely connected, I know which AP it's connected to and how long it's been connected). It won't pull an IP address via DHCP (it's on the 169.254.120.1 autoconfig address), but it resolves to an IPv6 address via envoy.local, so, yeah, it's obviously connected to WiFi.

So, how do I reset this thing? Do I need to reset the entire combiner (6C)? That seems like I'd be using a sledgehammer to squash an ant? I can pull the USB cable out of the modem, but I think that's actually only the cell modem hanging off the deadfront (and, weirdly, it doesn't power down anyway when you unplug it, unless it's got a really big cap in there).

Man, I really need ethernet run to this thing. An AP about 10 feet away doesn't seem to be sufficient.

Also, imagine if we could reboot the thing via Enlighten. Or just force it to reconnect to WiFi.

/u/Enphase_Support_Team would love to hear from you.

I'm looking for an affordable place to take a kid (16) to learn and play some pool. Round1 by the mall is $11/hr before 4:00, are there any better options?

I'm willing to invest in a membership/subscription of some sort if necessary; what I'd like to do is avoid spending a few thousand and emptying out half my house to fit a passing fad hobby...

My setup:

• Lenovo ThinkPad T14 Gen 6 (Intel)
• Windows 11 24H2
• Sonnet Echo 11 Thunderbolt 4 dock
• two MSI G274QPF monitors connected over USB-C to the dock

(This also happened on a previous Dell XPS 15, so I don't think it's hardware-specific to the Lenovo.)

I have my speakers connected to one of the monitors for cable routing convenience, and I have discovered that when I leave the machine alone for a while and the display timeout kicks in and the monitors power off, they sometimes re-enumerate in the wrong order when I wake them: the left monitor audio device becomes the right and vice versa. The machine itself never sleeps; this happens just from the display power-off timeout.

I asked an LLM (as one does nowadays), and it suggested that the likely cause is that Windows is tearing down the PCIe link to the Thunderbolt controller when the displays go idle, causing the dock to fully disconnect and re-enumerate on wake. This seems plausible to me. It suggested disabling PCIe Link State Power Management (ASPM) in the active power plan:

powercfg /setacvalueindex SCHEME_CURRENT SUB_PCIEXPRESS ASPM 0
powercfg /setdcvalueindex SCHEME_CURRENT SUB_PCIEXPRESS ASPM 0
powercfg /setactive SCHEME_CURRENT

This seems... overeager to me, at minimum on the DC front (because I don't want to reduce battery life when not docked, and I never have the dock connected when on battery). Thus, the question is, is this actually sound advice? Because this applies to all PCIe devices system-wide (GPU, NVMe, etc.), this could have a real impact on... I don't know what. If one googles ASPM related searches, one finds horror stories.

As an aside, the LLM also suggested disabling USB selective suspend. Same question applies: is that reasonable? I'm more skeptical on this one, because it's pretty clear to me that the audio "devices" are being routed through the TB4 system and not USB.

Any experience with this, or a better approach, appreciated.
