    EG4 Rack Battery communication between batteries

    You're doing everything you can - sadly, the documentation on these batteries doesn't live up to the batteries themselvelves. Q. Do you have EG LL batteries or which model are you using? I have two of the original Gyll batteries- which use BMS.tools - and one new Lifepower4 which uses...

    EG4 Rack Battery communication between batteries

    Try daisy chaining on RS-485, then hit search device in upper left quadrant of BMS.tools - list should populate itself. Then select individual batteries to view from pull-down list on right side. At least, that's how it works on mine...

    EG4 Rack Battery communication between batteries

    Eg4 Battery-to-battery comms are valuable when monitoring with PC software (BMS.tools and BMS.test) as it allows you to see actual cell voltages (plus balancing) and monitor any SOC drift between batteries... I use it to verify the charge parameters for my Schneider Conext SW4024.

    Signature Solar LifePower4 Battery - BMS Monitoring tool

    No password provided in documentation. I suspect you'd have to get it from SSolar. They would likely only provide one if it is restricted to read-only history info.

    Did anyone else run out and buy a 48V EG4 battery after watching Wills Video?

    Difficult to say. Did you use the PC software to report SOC or...? Different BMS manufacturers could affect outcome - also the unknown spec of cells between units. Wiring practices can certainly affect balance, especially in series. I'll be hooking up my Lifepwower4 in parallel with my Gylls...

    Schneider xw pro 6848 not powering up with eg4 lithium battery

    My post from another thread: The new Lifepower4 battery has a different BMS and Rs485 cable setup from the original Gyll batteries - and from the new EG4-LL models. Different software, too. Battery-to-battery communication daisy chain is a no-go between the old Gyll and Lifepower4. This should...

    Did anyone else run out and buy a 48V EG4 battery after watching Wills Video?

    Yes - the new Lifepower4 battery has a different BMS and Rs485 cable setup from the original Gyll batteries - and from the new EG4-LL models. Different software, too. Battery-to-battery communication daisy chain is a no-go between the old Gyll and Lifepower4. This should have been pointed out...

    Signature Solar LifePower4 Battery - BMS Monitoring tool

    Signature Solar provides a mini-cd with battery (at least they did with mine) which contains a pc program called bms.test. That program allows you to monitor cell voltages with provided rs485/usb cable.

    EG4 soc lights

    The last one lights up when it passes 75% SOC … So you may still have additional charging. When charging it blinks… Then goes solid when charging ends. This can give you a deceptive state of charge as there is a 25% spread for each light. Another good reason to have a coulomb counting meter or...

    Schneider xw pro 6848 not powering up with eg4 lithium battery

    Heads Up: Two entirely different BMS manufacturers - confirmed by Signature Solar telephone support today. And the software/interface for the Lifepower4 version is incompatible with the earlier Eg4-Gyll batteries. Unfortunate, since I have two of the old models and had planned to daisy chain...

    Gas-Powered Lawn Equipment Will Soon Be Banned In Cali, a broad category that includes generators.

    California has continued to press for higher fleet mpg standards. And electric vehicle adoption. And solar/renewables integration. It ain't perfect, but what is? Best not to confuse progress with perfection. The future is an omelette, not an egg...

    Gas-Powered Lawn Equipment Will Soon Be Banned In Cali, a broad category that includes generators.

    Despite its sometimes unfathomable attitudes, California's actions led to meaningful clean air standards, which among other things, caused the nation to increase mpg and decrease tailpipe emissions - to everyone's benefit. I suspect a similar outcome may occur because of its integration of...

    Schneider system design wasteland......no one knows anything.....

    FWIW I am AC & DC coupled off-grid using Schneider and Enphase equipment (AC coupled with Enphase for over a year - DC coupled with Schneider gear since 2015). My current system: Conext SW4024, MPPT 60-150 SCC (2), 3kw Renesola panels, Enphase M-215s (first generation), 3kw REC panels. Works...

    Micro Inverters VS String Inverter (The Shading Debate is Over)

    Since I am fortunate enough to have a Schneider SW4024 system which is both AC coupled (12 Enphase m215s, 3kw REC panels) and DC coupled (2 Conext SCCs, 3kw Renesola panels), I can say with some conviction (IMHO) that both have their place - and that a combined system has advantages over either...

    Adding storage to my Enphase system

    @GXMnow Always fun to read your posts. You really have made a number of remarkable examinations of the varying quirks and benefits of Schneider/Enphase equipment (including this one). One of the great benefits of Schneider is their robust graphing and data logging - it lets a user keep a close...

    Ideas for the definitions for these Schneider equipment settings

    Yep. SCP is a must, good to have buttons if the Gateway or Combox lose their mojo. And they can. I use the "live" Combox graphics (similar to Gateway) along with the Thornwave SOC for system monitoring

    Ideas for the definitions for these Schneider equipment settings

    What Horsefly said. (especially the 2% part - that's how you set the tail current) One of the nice things about LFP is they don't use temperature compensation. I skipped the Schneider Battery Monitor altogether, as it is relatively useless unless you have a Xanbus enabled battery (like the...

    I believe you have Rolls Batteries... I would talk to them and let them do the math - and double check the other settings.

    Schneider system design wasteland......no one knows anything.....

    True. I use my generator very occasionally - so I leave the SW gen input disconnected by default. That way, I can be ac coupled by default. When I wish to charge with a genny, I first disconnect the ac couple input - then connect the genny input breaker. Truth be known, with the additional AC...

    Nicely done. I had FLA for 25 years, kept the lights on, but I don't miss them one bit.My last set of Trojan L-16s are now in the well shed, driving an old Trace SW and my 240v pump. Using refurbished BYDs and new Gyll 200s for the house now. LFP (carefully wired/installed) are a robust...

    Nice work. These might help with the AC coupling thought process. I am barely able to keep up with a five year old, myself.

    Sw 4024 not inverting from 115ah lead, passes ac from Honda eu2000i. Two weeks no power,off-grid 40 years

    I agree with most here - you need a SCP to diagnose. Where are you located? I have a spare SCP (older version - It will control all the basics, but not a few of the advanced functions. You can update at a dealer, if desired). PM me, if you are interested. Good luck.

    Schneider system design wasteland......no one knows anything.....

    To me, this looks like an ideal situation for AC coupling. According to my understanding, you can add up to 6500 watts of AC coupled panels to the XW6048. Using micro inverters, (I recommend Enphase) you'll be able to get your additional AC power (during solar hours) and your DC coupled arrays...

    New EG4-LL Battery Communication issue

    In my case, with two of the older Gyll 24v models, I press on/highlight the Pack ID for next battery in chain in the menu (upper right in display) and then press return - it then shows readings for that particular battery. In my case, I know of no way to show both my battery's readings at the...

    BMS for Schneider Conext

    The SW4048 (like the SW4024) does AC coupling - provided you have updated firmware (something to think about if you are buying a used one). Updating the firmware is a precise process and requires either a Combox, Gateway or System Control Panel. Read up on it first. My SW4024 is AC coupled with...

    Schneider SW4024 initial review/use with Victron MPPT

    Be aware of "bulk termination voltage" - it can be set up to .08 lower than bulk voltage. It affects charging behavior - mostly in context to float/absorption when in combination with a SCC. Different forums have discussions on that interaction. Also, check to see that you have the latest...

    Schneider SW4024 initial review/use with Victron MPPT

    Congrats on the SW4024. I've been running my off-grid home with one for over 5 years... ac and dc coupled with Schneider SCCs and Enphase m215s. Starts and runs mini-splits, fridges, washer/dryers, toasters, et. al. As to the charging function - you should be fine as long as your various...
