Surely not grade A as advertised, and not as honest as I thought they were, but after six months from my first order with them , I did receive a small compensation of 6$ per cell for them giving me false information . The cells I’m referring to were CATL 310ah advertised, tested 285 to 293 ah...

I called it a relay, it is the contact Mechanical used in your BMS to provide source connection to the load. As in the pictures.

Can someone provide a link for this inverter, thanks.

Update, I have readjusted my absorb voltage to 58.4v, while doing test and trying to rebalanced my cell with the new one, I noticed that there's only 2-3 amps more to reach the full charge zone of 3.65v, stop at 10amps absorb. ( To top balanced only) So that means at 58.8v for 17 cells is 99...

Please don't be confused, I said it was 10.4kw on that one moment in time, but I know it fluctuate, I was just showing that it can be achieved in February. No mention of 70kwh.??? Magnum displays it like that, if it's 9.9kw there's no 1 in the front, but if it goes over thats how it shows. The...

Around that time of the year, the sun is really bright and the sky is very clear and clean, and it seems that with the coldest days the rays are strong, please note I said it starts mid January to have better solar charging. So it climbs up eventually more and more every day when it's sunny,of...

Wow, is what I say after reading this thread, but I agree with you 100%. You know what you need and how much solar production you are getting, so no need for any reason not to do it. I'm in the same boat, here in Canada Ontario, we get the best solar production starting in mid January, when it...

Update, I have upgraded to 17s, and everything is working out, my new settings, are 58.8v for absorb, and 57.2v for float, end amps is set at 34 amps, My question was, will this upgrade help at all? in any ways? I think it will, higher voltage, less current same wattage used. Just a thought.

Yes JBD-AP20S004 BMS is a 13s-20s, so very flexible. Thanks

I decided to add one more cells to each of my banks. I've just received and tested 8 more cells LF280K, and I want to see and test the difference it will make. I presently have 16s3p, and I will upgrade to 17s3p. So I will add 3.2v to all my settings above.

I've got the same BMS and I was also wondering if I could parallel them, I ordered two and paralleled them and are working really well, and I also have a 90 amps breaker on each banks. Six months after I added another 16s bank 280ah with another bms in parallel, and breaker, all is good. If I...

Hi happy to help, I have purchased 32 cells which were advertised as 310ah brand new,grade a, but once I tested them they were more in the 290ah range. They are CATL, and I like them, they are closely match, 289ah-292ah, . They have been installed in my system since mid June, and the delta is...

At this setting you're cells would be overcharged, my first setting was56.8v with end amp8ah, I gradually dropped it and now is at 55.2v 28ah endamp Float is good at 53.6v, mine is presently at 54v. I would not go any higher EQ stays the same as absorb 55.2 at minimum time. Rebulk 51.2v, only...

At 51.2volts, or 3.2v per cell x 16, is the number, which I consider or want my cells to be my lowest. I have grid power, so I use solar system during the day time for 12-14 hours (when it's high peek hours), and then it is set to standby mode for night time. If anytime we have overcast for...
