Need help with BMS. 48v, 300amp, 16 String. Need an intelligent one to monitor

[Robbo123]

Need help with BMS. 48v, 300amp, 16 String. Need an intelligent on i can monitor remotely. Bluetooth, LAN etc.
Will have 16 x 375ah LiFePo4 batteries. There will be a supercap between batteries and 3 x 5kw inverters for 3 phase.
Anything else you need to know? Looked at Chargery and Daly. None quite got to 300amp......

Orion Jr and Emus have remote monitoring if you mean via the internet. If you mean remotely via Bluetooth from your nearby couch then Chargery or Daly using a separate contactor for that many Amps.

Thanks for your reply. Im not sure what a separate contactor means. Would you have a link to one or an article that explains?

I worry that someone has "engineered" a super cap into your system.

I would expect that it would be totally unnecessary and actually brings it's own unique danger of fire when it eventually fails. Proper fusing for it pretty much negates any low impedance benefit the Cap brings.

PS
and I don't want to hear the word Diode used here either.

[Robbo123]

The supercap is for ensuring i can run welders etc and not spike the power draw. Please elaborate your concerns?

There are several discussions on using inexpensive BMSs with external contractors on diysolarforum.com.
I use an Orion Jr. BMS and their site can give your wiring diagrams. From what I understand you will be dealing with a lot of Amps and you may want to protect your pack with a robust BMS.

Why would you need a bms on a 16S system for? The Oriopn BMS is made for EV's. Got one I will gladly dump on you.

I won't NEED a BMS on my new pack after I top balance it.I rarely turn on the balancing anyhow. I like the information that I get about my pack. So that is why i am going to install it on the new pack. I had the Orion Jr from another project and it has allowed me to monitor the health of my Frankenpack of Nissan Leaf cells. That pack has various vintage Leaf modules that vary in capacity from 35 Ahrs to 45 Ahrs. There is still enough life in them that I can get some value from them on Ebay or Cragslist especially if I certify the remaining Ahr capacity.

Anyone know about seplos 48v 200a 16s smart bms?

No, but I see you've been advertising them on other solar sites. Please don't do that here without first obtaining permission from Solar Pete.
