Thanks for the suggestion. I had the chance today to check the cells with the Kilovault App. They measure in miliamp - 3287, 3288, 3288, and 3283. The voltage at rest is 13.1 v and SOC 76 %. Will h...

Just a note to all.  The resistor test battery simulator described above will work with the Q Series, but the 12V Active BMS uses active cell balancing and during startup it first tests this functi...

All the fancy math cancels each other out and it just becomes a function of the diameter of each pulley or sheave. If you have a 6 inch drive pulley and a 2 inch alternator pulley it is 6 divide...

How do I determine my alternator ratio? Is there a table or a math function I can use? I have a Yanmar 4JH5E with a stock alternator.

No Problem, The REC Active BMS is for 12V systems.  It can not be connected in parallel to create multiple 12V packs for expansion and redundancy, as the active balancers will fight with each ot...

Hopefully I am not intruding by asking a related question: For a 24V system, would it be possible to also use 2 REC active in serial?  Or is there a product designed for 8S batteries that also h...

And as your LTO batteries run such a high voltage I might consider a B2B converter on your important electronics.

Hi Rick, The leads to the alternator, basically just the field wire, are different by 36\" or so. All the positive and negative leads are landed in the same place.  The positive and negative cab...

When both WS500s are connected together via CANBus they will \"sync\" and basically treat your system as one big alternator.  This means that both alternator fields will be driven to the same outpu...

So I ran the boat for the first time with the new setup, and have a few issues I need some guidance resolving. Twin WS500’s running the 80A stock Denso Alternators on Yanmar 6LPs. I have LTO ...

Tank inputs works fine, I have 2 water tanks and one diesel. I found an old tread on Victron Community about this but no answer: https://community.victronenergy.com/questions/59623/cerbo-gx-o...

TAR,   Well, that is disappointing. That was one of my motivations for installing the Cerbo. No, I haven\'t gotten as far as trying to get temperatures and tank levels displayed at the helm, yet...

Thanks. Yes I have one temp sensor on each alternator to the Cerbo. But I have not found an way to get the Cerbo to send this temp data over NMEA2000, have you? Battery monitors, VE-BUS de...

Good luck getting Raymarine to mod their firmware with this feature in our lifetime.  ;-/ I have a similar set up: Raymarine, Victron, Wakespeed, Balmar.  So, another idea....   I ran a separate...

A quick follow up,  we have verified this behaviors with one of our Beta testers and I have an Email out to REC -- REC and Wakespeed to work to improve the EOC handling.   And noting als...

This is a great example of what happens when the Smart regulator can not talk with the BMS.  With an integrated system the BMS will send a signal to the WS500 to start to taper back as it approache...

Have contacted Kilovault and received a reply that is basically what they have printed in their brochure. Limit  the voltage to 14.1 v. Since then I have raised the VBat set point to 14.2 volts....

Hello Trond, Can you post your settings from the REC ABMS? How big is your battery bank? Maybe I have some suggestions if you give more information. For example it could be that your ba...

Not Neil, but will give some ideas... CAN has three different wiring \'topologies\' that Wakespeed commonly supports: RJ45 (With a variety of different pin-outs) DeviceNet (aka:  NMEA-20...

I have seen this before while working with BMS manufactures in proofing reliable Alternator based charging systems; the \'Twitchiness\' I call it seems not much of an issue with pure electronic cha...

Appreciate the feedback; at issue I think is the wide use of N2K and how it works on a wide range is displays.  Because some PGNs are reused for a lot of different sources (Battery, Alt, etc), we h...

We do have some hidden hardware feature to exploit in future firmware leases; a prime focus for 2021 has been expanding the know well supported battery systems, and focus on features to assist inst...

Trond, This makes sense, when you are dealing with large charge parameters the PID can get a little twitchy.  It sounds like you may need to increase your Proportional and reduce your Integral a...

When running CAN bus regulated charging the A-BMS starts to reduce the max-discharge allowed in the system when the first cell reaches \"Balance voltage Start\". When running solar this runs smooth...

This looks like it was a while ago. @neilfluester Can you post a diagram of your setup?

There are different ways to program the WS500. I would advise the \"Universal configuration Utility\" You can download it from the Wakespeed website including the manual. In short: Unzip th...

You made a good point Edward but the challenges are many on this one.  For background, we developed this app to support Wakespeed as they worked on the actual hardware and each product must stand o...

I am the owner of a SW development business that is 100% Macos, Linux, and embedded systems.  Not a single Windows machine here.  For me, the lack of  Macos (or Linux) SW makes the Wakespeed a non-...

Hello Don, from KiloVault manual. Absorb Voltage 14 Volt Absorb End Amps 2 A Absorb Time 2 minutes or less Not clear for me, is what they like, 14.0V only for 2 minutes, or 14.0 till t...

Hello Paul, What you like, a small amount of rotor current continues can be programmed in the regulator. Look for command $SCT    <Tach Min Field>   But be very careful with this settin...

Agree  

If motor is not running or tach is zero, reduce rotor current to 5% or similar. Just enough to sense if motor / tach starts. Removes chance of cooking rotor.

Most battery packs are set to 14.4 and fine up to 14.6 volts, provided they are fairly well balanced.  You are likely better off using your WS500 and increasing the VBAT setpoint vs relying on an i...

Have been monitoring SOC with the Balmar SG 200 and Kilovault bluetooth app. The Kilovault app  reads consistently higher by 7 to 15 % so I have been switching to internal regulation at the alte...

Don, the WS500 is doing exactly what it is supposed to be doing, so lets look more closely at your battery pack. The problem seems to be with your SOC reading.  Remember that SOC is just a calcu...

After startup at low engine rpm the system goes to bulk and  charges at 20 to 30 amps. When rpm is raised the amps increase as does the voltage to 14.1 volts. That is the VBat set point in line ...

Thanks, its more like an nice to have feature. Lets say you have an client with an installation not working as intended and he sends you the log file. Than this field current data could be us...

Thanks. I hear what you are saying, but it would be nice to be able to control the charger instance yourself. 49 by default, or 0-4 if i want to.   Its not just the Raymarine MDF b...

\"Is this reserved for future HW versions?\"  Yes.  <smile> We have many deployments with two large frame alternators (ala, 24v / 280A large frame Leece Neville alts) and no issues.  The d...

ARG -- NMEA and details... As you found, the WS500 is able to send \'NMEA2000\' like messages via CAN, and uses 127508 as a way to send out some otherwise unavailable details for the alternator,...
