I would start by testing the voltage of each cell, then try charging each cell individually. If the cells take a normal charge and are acting fine and the problem still exists, it must be your BMS misbehaving.

Wow, sorry to hear @terrango - so far no issues with any of my cells, but if support is as poor as you indicate then others should be careful!

7kW/day sounds on the high side for the usage you outlined... how did you come up with the 7000 Watt hours per day? I also like the Growatt units... the 3kW Growatt units are quite quiet and rock solid.

It's working for me... I just logged in using this URL without issue: https://server-us.growatt.com/login

No, I've never tried - scared after reading all the reports of failed software/firmware updates for Daly units :/ You can set the SOC manually if you want - or when you charge the pack for the first time it should reset to 100 percent. But I'd contact your supplier and/or Daly directly for...

Sorry I don't have any theories... I own 6 daly's and have never seen this behavior. What do your individual cell voltages look like, normal readings? I assume you've triple checked all your connections?

That's not normal for a stand-alone pack... it should read 0. Did you connect it in parallel to other batteries? If in parallel the other batteries may be drawing from it.

I wouldn't say that's accurate... I get 100 percent output from my panels (sometimes more), and Will Prowse seems to think that's pretty normal: https://diysolarforum.com/threads/12-year-old-solar-panels-still-producing-over-100-percent-rated-power.64457/

Confirming some old panels are working OK before mounting them on my bunkie roof, and was happy to see they are still performing ABOVE their rated power output 12 years later! How are others finding power degradation over time on their panels? These are 230 Watt Canadian Solar panels - 4 in...

If that's the USB dongle you guys are referring to, then this is what I do when my plants don't show data: -check to see what the light looks like on the USB dongle... is it solid or blinking? which color is it? When this happens to mine, everything LOOKS ok (ie the light is blinking blue...

Will Wen from Daly BMS recently posted this DIY battery instructional video... some good tips in there even if you don't plan on using a Daly:

I noticed today that Daly now has a "wifi dongle" that provides remote monitoring... not much info available about it yet though:

Thanks again for everyone's advice - not sure why I haven't seen this issue previously, but it was definitely due to voltage drop from the battery clamps on posts. Switching to ring terminal leads solved the issue completely... thanks again guys!

After placing two orders in the past year that went very well, I'm happy to recommend Shenzhen Hongxinda New Energy Co. as a reputable supplier of LiFePo4 cells from China: https://hongxinda88.en.alibaba.com/ The sales rep I worked with was Eric Wang and I have been very impressed with his...

Also - based on everyone's feedback, i'm going to improve my setup by getting rid of the alligator clips and lead clamps and replace everything with ring terminals for future testing ;)
