Your youtube link, https://www.youtube.com/user/daromeresperyd
...maybe my phone is just dumb... I searched for you and found your videos though. Thanks for the uploads!

Thank you for any help that you can give me on this,

CAN bus control charger has much finer control via the BMS (preferred method for last 5 years) than the "enable" version which limits the BMS to interrupt only with the charge logic dictated by the charger. Have a read of the how to guide to setup the TC-Charger.  

https://www.batrium.com/pages/how-to-con...a-watchmon

Make sure that the maximum voltage of the charger is suitable, we have seen several sent which were too low from supplier. For 4.10v @ 14S configuration the charger needs to reach at least 58v. The charge rate for the model you listed looks to be 80A so this is a significant rate that needs to be throttled back to 1A when balancing.

Before purchasing you need to also consider discharge too, my recollection your project is a RV so need to consider all charge and discharging methods.

Thank you for taking the time to answer this one.

I read the link you posted, I'm glad you have such a great FAQ section.  The project I'm actually doing is add a battery powered inverter to my solar panel system.  My current StorEdge system now shuts down when ever the grid goes down.  I want to add a second inverter that I can run my house on during this situation and also to supply a base of around 1.5kw to cover usage during the remaining high cost time of use, after the sun goes down.  I plan on charging the battery during excessive solar power production and/or at night when the power is cheaper,  if needed.

My planned 18650 battery will be 2 14s60p strings in parallel. The batteries 2100mah to 2300mah  LGEAMF11865. I already have ordered the Batrium BMS system with 14 longmons and 1 shunt.  ( I'm still wondering if it would be best to have one shunt for each string? ) I'm not sure what would be a good inverter for the 240/120ac system here in Wisconsin ... suggestions appreciated.  Wink

I went with the Elcon TC style charger per Batrium's recommendation.  I also went with the higher output charger because I may need to charge at a higher rate during the day.  That is way I picked the TC HK-J6600 unit.   EV Components sent me the following documents so I can check if this unit will work with the BMS properly.  They told me that the unit output can be controlled by the CAN bus communication.  They sent the protocol sheets to me, which I'm attaching.

Will this unit CAN bus specsnwork OK with the Batrium, any special programming issues? Do I need to purchase any additional interface items to go between the charger and the BMS?  Lastly, if the charger is too big, would I be better off with the smaller charger shown in the BMS how to FAQ?

Darn, the message keeps telling me my message is too long.  Trying to put the EV Components info here.

Or they give me these options, which I don't think would work out for me.

Thank you for your help. Just getting into this area and I'm enjoying learning, but the meds they have me on right now really aren't helping me to figure out things on my own.   I'm so glad I found this forum of "Brain People"  Smile

The current BMS system only supports 1 shunt. For external use you can add as many as you want Smile

Use bigger cables;-P

@bfleury

I read you have the storedge system.
Why shut the system down when the grid goes off?

Here I'm preparing my battery bank to test it on my solartracker with 700pW power. If this work and I understand the system I was planing to make a 10Kw ba hooked on SolarEdge inverter/Storedge. But do you have LG Chem battery or tesla's powerwall.

Hi,

I paid extra for the StorEdge to use a Tesla Powerwall.  I've had one on order since they first came out, since the 1st version I paid the downpayment for the PowerWall2 and just recently got a email saying I may get mine after Oct.    I cancelled the order after finding this site and decided to do one myself.   You have to add the cost of changing your service again in Milwaukee area, plus the required "Commissioning, Authorized - Licensed contractor installation costs". They what you to go from 2 meters to 3 meters so they know what your battery is doing?   They had it so you had to have 5 meters here, but the contractors got them to go with the 3.  I have to pay a monthly per meter charge here on them also.

I then found out that the only battery the StorEdge will accept is the LG and Tesla, the tech help people were pretty short with me and just stated it was impossible to run any other type of battery power into the unit to power the critical load output.   So it will be cheaper to save the Tesla costs and just build my own wall and install a separate inverter system for it.

PS.  I did figure a way to get around their restrictions to use the StorEdge.  I ordered a P400 converter, added it to a string and instead of attaching a solar panel to it, I'm just feeding it battery power.   It does have the same issue of being shut down when the grid goes down though.

Hope this helps you.

I just ordered a Batrium kit, watchmon, longmons, and the shunt.  Anything else i need to/should buy/order to get started or should that be good for the initial setup?  Other than seeing Pete's videos on the system i really haven't done a ton of research on the different addons or specific wiring diagrams, etc.  I have an mpp inverter, i know there's something that some guys are testing to control the inverter, but that is still in the works so no need ordering that controller yet i don't think.  Do i need a seperate charger for the balancing function?  I'm still doing some research on a good shunt trip, but that can be done once i get the system.
