Hi there i am interested also to silence the alarm i have also rec q Where can i get it?   thanks

@Ben "let us know the result with new settings." Of course, let's wait 24 hours, I can already see that your settings work better. "Maybe your old firmware didnt support CFVC, and you made not t...

The sun island capability for grid feeding is very limited. The system has to be setup as a battery backup ups rather than an off grid system.   Rick is correct re firmware causing issue...

You may want to consider adding one of these to allow your DD alt. help charge and top off/balance your pack while on the road :) https://ogm-energy.com/products/orion-xs

I will charge only with the magnum inverter charger when plugged in or with the 20kw genny running.    I have a 350amp 50dn alternator on the Detroit series 60 but will keep it out of ch...

We have quite a few customers with SMA grid tied systems so hoping they might be able to help here. One issue that came up recently was some firmware bugs in the SMA where it has problems communic...

Good catch Ben!  

yes, a 12P4S should work well for you.  Connecting the 12 cells in parallel is now commonplace, so long as you are working with fairly closely matched cells.  I think you will notice a go...

@Christopher I put your settings in a calculation sheet with the formulas from the manual. Result in: Bulk charge max 14.18V Float 13.08V Restart charging, if below 13.04.   If you volta...

It turns out that I was powering the WiFi module from the switched side of the contactor, and not the pack side.  After fixing that, the update worked perfectly.  Thanks to Rick and Tine ...

i am starting to work with trevor at higherwire. i want to make a 1200ah 12v setup for my coach. using 3.2v 100ah calb cells.    so would do 12 in parallel and then 4 of them in series....

We recently had a customer swap from lead to lithium to power their Sunny Island 6048s. They are grid connected and are no longer able to export to the grid, though they were able with lead. We ad...

Thank you very much for the older version, I already installed it. Regards

We just added it back to our REC NA website downloads.  Here is the link https://rec-bms-na.com/product-manuals/#7-8-wpfd-rec-active-bms

  Even though SOCH is correctly set to 95%, the system does not resume charging.Everything worked very well with the previous software. I updated to 2.92-2 and have problems.Where can I downl...

I’m having trouble updating the firmware on a newly purchased Rec Active BMS via a Wifi Module. The Rec Active BMS is 1A-2024, HW version 2.1,  currently running 2.90-1.   The...

Yes, I am not your client, I am REC d.o.o. Slovenia, but there I often don't get an answer.I read your furum and I see that there is excellent support and very nice people.Coming back to your quest...

We dont see you as a customer so I can't see what tool you are using for configuration but we are happy to help none the less. Not sure what the support comment was all about... The wifi module ha...

The maximum current that we can set in the REC Active BMS settings is 350A, I need to increase it to 500A.Can I count on support?

We have just created several REC BMS kits to make it easy to purchase and save! You can find them here. REC Active BMS Kits REC 2Q 16S Kits REC Large Scale High Current and High Voltage Systems

@Rick Thanks for the notice. @tine Thanks for the quick turnaround. I have downloaded and installed the new version 1.6.3 (for HW v1.2), and confirmed that the version displayed is now 1.6.3 Un...

REC has fixed this bug in its latest release.  You can find details here. https://rec-bms-na.com/rec-bms-wi-fi-module-firmware-update-1-6-3-just-released/

After working with Wakespeed for more than 7 years we grabbed a Zeus around Christmas and threw it onto a test system we had set up.  It was still early in its evolution but seemed to be built...

@sturla Hello. Thanks for the reply, makes sense -- holding the SOC when desired.   The next release of WS500 firmware (2.5.2.) is in fianl QA and we can not make any changes, but wil...

Thank you for picking up on this one Al! The installation is on a 44 fot sailboat, with a Volvo Penta D2-55 engine, with two Delco 28si 200A alternators attached to it, one WS500/alternator. The h...

Hello, sorry for the delay. What is happening here is as the WS500 is running in Slave Mode it it following the directions of the REC BMS.  As such, there is no 'Float' to force to ...  ...

@Al Thomason ; Do you have any idea why I can´t get this to work as intended? 

In my continuing regression testing of an existing two-contactor system (Charge Bus and Load Bus) that has been upgraded to FW 2.9.2-2, I have uncovered the following error: I was trying to test t...

Hi Sturla, When the REC BMS is connected to the WS500 it will take over control of your Alternator charging but all safeties and interlocks should still over-ride the DVCC/CVCC control signal from...

Hi All, I have a sailboat setup with REC ABMS, 2 x WS500(200A alternators) and a Cerbo to monitor and control my LFP bank. All items involved run latest available fw versions. System config; ...

no, they are meant to drive something like an LED directly.  If you want to drive a larger load you will need a relay with a very low (15ma) draw or a powered relay like this. https://www.ama...

Do the Opto lines have enough current capability to directly drive the Tyco EV200AAANA 500 amp contactor when connected in series with it and a 12v source? (observing correct polarity)

Yes, you are right. IT is a firmware bug. I have tested this in the morning. If you set it to °F then it gets data from the entry window and sends it directly to the BMS without converting it ...

@Darryl  I only recently upgraded to FW 2.92-2. In the middle of trying to make sense of all the changes to the use of the relays and optos, I noticed once again that the WiFi homepage was re...

I have further info on the error.  The underlying BMS messages always use °C. Apparently, the values that are input on the page are always being interpreted as °C regardless of the opt...

Thanks for the feedback.  Pushing it on to REC . @Tine Andrejasic
