Vertical cantilevered wall mount rack.

Except they did, based on previous customer reports, and then confirmed it themselves. If you guys need this level of assurance, why not get a solar installer to handle things for you?

You're gonna need to diagram what your setup is right now but I think you need to have one inverter take it's positive from battery 1 and negative from battery 4, and the other inverter, the exact opposite.

If you really want to go all the way down the "No true Scotsman" rabbit hole, unless you're mining everything from ore and operating your own rolling mill, you're not DIY, right? If you wrote a check to Tesla, Generac or some other integrator/installer then you're NOT DIY. If you're...

That some folks feel shifting integration risks to a retailer is reasonable baffles me, especially on a DIY forum.

What are the odds that he's got four "bad" batteries though?

This is what the Pylon protocol permits. I presume other protocols are similar. You can see the inverter slowly ramping charging voltage and then step down amperage as the SoC approaches 100%. (The jump in current after 8pm was me manually adjusting the current limit on the inverter. The...

I've got a DLG which has similar (low) limits; they're using physically smaller cells so the current limit seems to be limited by the cell rather than the BMS (which doesn't seem to be cheap.) The Amphenol RADSOK connectors also have a 120A rating, so you don't want to be drawing more than that...

Or... a battery that masks some underlying problem that's still lurking in the particulars of your installation.

First page. setprt set protocol type - setprt [VICTRON/GOODWE/GROWATT/STUDER/AFORE/LUXPOWER/KEHUA/MEGAREVO/SOLAX/PYLON/SOLIS/SCHNEIDER/DIP] I'm using the LUXPOWER setting for the XW - the SCHNEIDER mode was reported not to work.

Yet another reason to use compression fittings.

I'm currently sorting out bus bars myself.

The remote initiator shuts down everything. The local disconnect just breaks connection to the PV.

Quite sure. Verified against what I'm using now.

That's actually a concern given that cold shoulder I've gotten from some vendors. I want to see vendors continue to offer products to the DIY community, but if that community gains the reputation for beating up vendors over integration issues outside of their control then I'd anticipate more of...

Will has a whole video dedicated to pre-charging inverters. If this is necessary to avoid triggering BMS current safety limits then a better question may be are other batteries that "work" a result of higher limits? No limits? Difference in BMS processing power/current sensor resolution?

Empirical testing, initially, later confirmed by reverse engineering. DIP switches only change the CAN protocol type, as far as I know. ... FUN_0001da10(&UART3,0x2580,uVar1,uVar2); UART_Enable_FIFO((int)&UART3); set_UART_Interrupt_FIFO_Level_Select((int)&UART3,2,0x10)...

Schneider's "Li-ion Battery Solution Guide" says in the "Supported Architectures" section that "Currently BMS communication is supported for systems with a single XW Pro inverter..." I figured I'd try anyway. I've got two XW Pros and set them up as master/slave and duplicated the settings and...

From my RE of the BMS firmware, it looks like the speeds are fixed.

I should have been explicit, but you're exactly correct. This also makes sense that the "workaround" of using the SCCs to power the DC bus would work; you're certainly not pulling 15,000 amps from those.

Check out https://ctlsys.com/products/. This will apparently let you setup for zero-export/sell. I skipped the SCP and just use Insight (Facility).

You've got two inverters connected; my concern is that depending on the model you may be able to exceed that current with a single inverter, let alone two.

Or use a line side tap and avoid the 120% rule entirely?

Insight Home terminates one end of your Xanbus; Facility has two pairs of Xanbus ports. Facility has two RS485 ports, two 0-10VDC analog inputs, two 4-20mA inputs and two relay channels (NO/NC). Facility can mount to a DIN rail. Is all that worth an extra $300? Dunno.

I can't recall if you covered this earlier in the thread and I didn't get a good view of your EG4 bank wiring in your video, but would you mind detailing how they're wired? What wiring is the same when you use other batteries and what wiring is different?

Mismatch with the console seems to be related to ADC noise. Full output of decoded RS485 "LVP" data: $ .build/lvp_test -c 0x61 System analog data 1: 53.200 V Overall...

The "link" ports are also using RS485, so the "urates" setting might be for that. I do see code that conditionally sets the BMS link port to 1200 or 115200 though it appears to be related to the BMS running in slave mode (I think that the link ports come up at 1200 baud and can shift to a...

I got wire ways from Gordon Electricals Supply. They aren't cheap and you'll need a panel punch (ideally) or a step drill.

The serial console lets you query cell status, but the RS485 interface doesn't have any of that info available.
