I am looking at putting a Low Voltage Disconnect between my battery BMS and Giandel Inverter, as I don’t trust the Inverter’s LVD. 24v system, needs to be a 200A - 300A LVD and I would like to be able to adjust it. Any suggestions?

Thank you for this info. I just got a Morningstar Tristar.

I tried supplying 12v and then 24v DC but each time I switch the switch over to external power the BMS completely shuts down like it has no power.

Here is the screen shot

So my BMS seems to be tripping off because of cell voltage difference again… it is exceeding 300mv

Are Samsung EV Lithium Ion 12s 44.4v a good options for building a 48v small off grid system? I am thinking of using maybe 6 or 8 in parallel for a cabin. Or are LFP still better?

I’m looking for a breaker for 120v AC to use after my 4,000w (6,000w surge) Giandel Inverter. It will go between my inverter and main breaker panel. My inverter is about 40’ from my main panel. What do you all use for this situation

Any updates on this issue? I'm getting the same error with my Giandel (silver) 24v

That's it! Thanks so much. It was at 250a I set it to 300a

My Chargery 300 BMS is shutting off the batteries occasionally when I use my miter saw… no fuses are being switched, it just disconnects and I have to reboot the BMS, then it works again. 24v system, LFP 280a, 16 cells 2p8s configuration

Okay, good to know. For connecting multiple MPPTs to a LFP Battery build, do the SCCs need to be able to connect and communicate to each other as some people seem to imply?

I'm planning to purchase 2x 60a SCCs does the brand matter? Cheapest here is Renogy, and Epever, then Outback and Victron. Which would you guys recommend?

Interesting. So will the damage be apparent? I connected my 40A Renogy Rover SCC to my panels without the batteries briefly, could that be why it doesn't disconnect on high Voltage?
