ok but where do i plug in my CE can to NMEA2000 adapter?

Neil,   The low limit for warmup delay is hard coded into the regulator, so even trying to set it manually with puTTY will not help. I am not sure that using the lamp will help you, b...

You should be able to connect your Multi to a VE.bus Connect your REC BMS to the VE.CANBus port 1 Connect your WS500s in series to VE.CANBus port 2, with a terminator plugged into your last W...

I currently Have 2 WS500 installed and in the app i have set the start-up delay to 15s which it says is the lowest it can go. i have the D+ output of the balmar alternators connected to Lamp of the...

so i have just installed 2 x WS 500\'s and am a little confused with the can wiring when integrating with REC BMS and victron. i have the Cerbo GX which only has 2 ports but i need to plug in: ...

You can find the complete list when you build your BMS kit here.  After adding accessories just specify what Inverter driver you want. https://www.offgridsoftwaresolutions.com/product/rec-si-bms/

The CANBus connection to the Victron BMS is pretty straight forward but there are a couple of things you need to know.  We will update this topic as new issues come to light, and we will add them t...

Good Question. If you have two relatively small alternators and are not concerned with limiting the output of each alternator you could go with a \"Battery Centric\" configuration and use only o...

I\'m looking to install 2 WS500\'s for our twin engine boat my question related to the shunt or Shunts requirement. do we need 2 x shunts 1 per alternator or can we share 1 master shunt at the batt...

Not yet that we know of, but its a great idea.  Later in the year, time permitting we hope to put together some examples like this.

what kind of different inverter interfaces?

slightly off topic but is there a diagram like this that shows the REC ABMS integration in place of the victron bms?

It sounds like you tried to wire your cells while the harness was connected to the BMS.  The maximum voltage potential across your cell monitors is 5V DC.  If you were to connect your ground, then ...

In case other users need the answer: We had blown four fuses. There are six (?) in total. The REC only ships with two spares, so now we wait! The fuse you need is \"t3 15a 250v cq mst\". I...

Hi there, We\'ve got a REC ABMS, but we\'re having trouble getting it to start up. We\'ve wired everything up according to the diagram below and checked everything twice. When we hit the BMS ...

Hey Patrick, if you could share with us a summary of what you are trying to achieve with the 4 packs and maybe some sequences of operation or pseudo code, it would help us give you some meaningful ...

Finally finished my second battery build, although these are just minor capacity cells (20aH). Slightly different in that I have used the REC WiFi module instead of the Bluetooth Module. Lots to le...

Feedback from Tine of REC You can make 4 way circuits with small signal relays or optocouplers. NC output of the relay is used to power LED or alarm in case of the blown fuse.  

The Lynx Distributor does not look like it supports CANBus but just uses a simple I2C or 1Wire interface on the RJ10 connector.  The REC BMS supports the 1wire protocol for its temperature sensors ...

According to the Victron Lynx Distributor manual only the Victron Lynx Smart BMS can communicate to the Lynx Distributor.  Is it possible to get the REC Q BMS to do work with it?

Hot off the presses from the Victron Energy Community website showing the WS500 as part of its total energy solution for 2021. Check out the Victron github page as posted on another forum page f...

Ok, the short answer is yes, with a caveat.  The WS500 uses a different pin out than the standard VE cable and may put voltage on your network if trying to use a standard cable.  There is an intern...

Hey Ryan, Here is the latest drawing that includes the WS500 from Victron hot off the press.  I haven\'t even reviewed it in detail yet myself but thought it might be an interesting read for you...

I have a pretty extensive Victron setup and just recently connected it to my NMEA network via a ve.CAN -> NMEA cable. Can I take the ve.CAN bus network that is daisy-chained to many of my vic...

Thanks for sharing !

Thanks Rick for your comments and commitment. I am currently building my second 20aH battery, its just minimally breadboarded now. I have the two batteries connected to a Cerbo and find some int...

As it stands right now the REC architecture is designed in such a way that the Q series with a master controller that provides supervisory control and monitoring is the way to go for a complete int...

Hello I am interested in this posting. I will trying to connect 4 LFP batteries in parallel using 4 REC BMS units. My plan so far is to use a Victron BMS-712 battery monitor and/or a Victron Cer...

Thanks. Please let me know what REC says about the software being able to track two separate batteries/BMS\'s vs just 4 \"cells\".

Correct, you would just set each WiFi device to a single unit.  I haven\'t tried it yet but it might be that your WiFi modules could each act as a backup, giving you redundancy at that level too.  ...

Thank you for the info. Look forward to hearing what REC has to say. One additional sub question would be: If using two WiFi modules, would that allow for history logging from both devices? T...

Great question. First, the 2 BMS\'s can indeed share a WiFi module but they need to have their RS485 addresses set differently and then you can then just select the one to communicate with once ...

12v RV with the new Victron Multiplus II.  Any issues with using a pair of the these BMS\'s in parallel?  Considering having the redundancy of a pair of 2P4S batteries rather than just one 4P4S bat...

Hey Neil, There are two ways to limit the output on your alternator with a WS500.   For low RPM you can add a factor which will reduce the output at lower RPM, provided you have your ...

I wanted to check if it is possible to cap the output amps of an alternator using the WS500 I want to use a high output alternator that has a really good output at low rpm on a single V belt but wa...

A new release of the WS500 configuration tool is now available. If you have a working installation you can order the free download here. https://www.offgridsoftwaresolutions.com/product/ws500-so...

That\'s likely a bit low and may generate a bit of heat.  If you have lots, just put them in series in sets of 4 per drop, for a total of 32 (4x56 ohm= 224 ohms).  Right in the range that Tine sugg...

@tine @rick_tech_support any issue with using something as low as 56 Ohm?  I have a bunch laying around and was going to use them?
