so i have a 48v battery bank with 16 3.2volt 280 amp hour cells. one time before cell #11 died before the other cells and would also charge faster than the rest so i changed it. everything was fine for a while until it started happening again. i changed in out again with another new cell. i...

I have switched the leads but I have since disconnected the power supply because I was out of town for the week. I will be back late this weekend and will reconnect it. All of the cells are still connected in parallel so maybe that helped them along a bit. But before I start top balancing again...

I’m currently doing a top balance on 16 280ah cells. I have the cells in parallel and before I started the cell voltage was 3.27. The power supply is set to 3.6 and the amps haven’t gone down in 2 days, 48 hours. The amps are sitting at 5.6 exactly and the test started around 6.34 amps. Am I...

Yea I did add studs to the terminals due to them being so weak.

Hi guys. So I bought a LV6548 and I am getting ready to install my new santan 250w used panels on the roof. I’m going to run 2 strings into the LV6548 both of witch will be hooked into a metal shutoff fused with 30 amps. Also I plan on grounding the metal shutoff to my grounding black outside. I...

Yea you guys have a good point on that. I didn’t even think of the bus bar layout

i did top balance when is build the battery but not since then. checked all the connections but will check again. currently i have an overkill solar bms and eve cells. as of now im running the bus bars to the terminals first and the bms leads on top of the bus bars. I've had this battery for...

Sorry the reply took so long, but yes I did figure it out. I had the back to grid setting set to 54v and that’s why it never would switch over. But I figured it out and it’s working great. Only thing now is on the WatchPower app I can not see the history. Every time I try to check it, it logs me...

Hi guys. I have a new lv6548 hooked up and no matter what setting I put it on, it will not pull From the batteries when the grid is connected. I want it to pull from the batteries and solar first. Then once the batteries die and there’s no solar I want it to pull from the grid as a backup. Does...

I did find some more information and did end up grounding the panels as well as installing a pv combiner box with all the proper Fuses and surge protections. Thank you
