    Schneider xw pro 6848 not powering up with eg4 lithium battery

    The support guys would probably welcome that particular call. Something tells me it might be an easy fix.

    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...

    Schneider xw pro 6848 not powering up with eg4 lithium battery

    Late to the party, but afaik, I've seen no mention of using the reset "button" on the Eg4 batteries...

    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...
