I HAVE THE 3.2KW AND THE 5.5KW...THE FANS OF THE 5.5kw run more frequently..with or without any significant load.. i also noticed a huge disparity from battery load/dc and house load/ac. the fans run noisier when you have a big load running say above 700w example..the battery load will be...

I carelessly swapped the battery out and pv in cables to the charge controller. This released the holy blue smoke + some gray ones as well? Lessons learnt, dont be thinking about an upcoming expedition to everest, while working on sensitive stuff

great resource here, am a newbie fixing to build a simple 48v 560ah bank.guess i have tons of reading to do, as my plan was to have 2 parallel banks of 48v 280ah with separate bms....end of story:)

rept might be the new lishens, only time will tell, xuba has started selling them as well. seems no one is willing to be the first guinea pig on the forum

I had similar issue, when i hooked up 14 x 330w panels in series,Voc 39v no high voltage warning, but inverter refuse to charge battery well, till i reconfigured to 7s2p, all is good now

IMO, nothing special...just get a 200amps 4s daly or jk bms with Bluetooth and replace

Ahha, these are rept cells. Likely 220ah and not 280ah. Some users here got decent ah from rept cells.

SELINA of shenzen dery, formely of Xuba is doing great. Another Amy https://dery.en.alibaba.com/?spm=a2700.12243863.0.0.7deb3e5fCx2uWB

@ capt bill, thats a sad experience. Xuba didnt extensively test the replacement cell before shipping out?....that sucks

yeah, a 2yr old installation. turned out to be a loose inverter-external busbar connection. tightened, restarted and was good again

chat them up on alibaba, they would respond promptly..revo ii boards are expensive. almost 300usd for the main board last time i tried fixing a damaged unit. didnt bother...would rather buy a new cheaper unit for 250usd. the revo ii series is old now...best to try the hmt/hes models, with smart...

Oldest unit is about 10months. 1 unit wasnt earthed and got damaged by a lightning strike, Sorotec sent me a replacement board free of charge with my next purchase. If you have less than 500usd to spend, fo for sorotec, if your budget is upto 850usd, go for Growatt, if you have upto 1500usd..I...

Got a similar used fla battery from a pal, will use it to swap out the bad battery, and see it how goes. intend to go LIFEPO4 whenever this bank goes south permanently

Done???

Yeah, Amy says her CATL s are grade b, with scratched of qr codes. I wonder if prices will come down in March, am really in no big hurry. Sad i had a quote of $72 for same lishens in November.

sUBBED. also looking for a decent 16s 200amps bms

thanks for the heads up, fire??, not worth the risk!

HOW IS the higee cell performing now?

yeah, the sorotecs have higher idle consumption of 40w to 55w....other hybrids are about 20w to 35watts. mppt range is 450v...but works best 250v to 350v. what is the voc of the panels you connected, how did you string them up?. i had mistakenly lined up 14 pieces 330w panels with 39v voc in...

Wow, thats sad. Did the cells arrive under 60days?. Learnt alibaba protection is 2 months max, afterwhich funds are released to seller. So what happens on the off chance that freight duration exceeds that time, and money released to seller. If issues arise on the cells, how easy would it be to...

your bms has probablly tripped off discharge. can you access the bms settings via bluetooth or pc? use a multimeter and try to read the voltage at your battery terminals. you need to find a way of re-enabling/reactivating the battery

NICE, HAVING YOU HERE. DO YOU KNOW WHERE I CAN GET the manual for the daly smart bms 250amps 16s. am setting mine up and looking for the right settings to use to configure the bms

If you properly top balance the 4 cells, you can use it without a bms for a while, a lil risky, but risk is reduced greatly if properly top balanced. I used mine without a bms for about 3wks, and it behaved ok. You can go a step further by attaching small digital voltage displays to each cell...

I have it, both 5.5kw and 3.2kw. works ok.zero issues. Deye brand appears to be the best of all known chinese brands. Compares favourably against the victrons and Magnums

i would find another with similar capacity rating and similar charging float and absorb charge voltages...and call it a day. i am having a similar challenge as well. thinking of mixing fla and smf to make a bank of 48v, though would not equalize so as not to dry out the smfs...wish me luck!

yeah, this is the best bang for buck reliable mppt CC, i have come across. gets the job done, no frills

What was the cost per cell, shipping exclusive? .I got 83usd for 300ah Catl cells from xuba

so the sorotec lithium support is all but rudimentary...i selected lithium battery and everything is all grayed out. how does the lithium support work? i ended up editing the bulk and float voltage settings to 55.4v and 55.2v respectively for my 16s 280ah lifepo4 bank

the case is a custom built metal case, bms is JK-B1A20S15P I spliced and extended the on switch cable by about 10 inches. by Bluetooth device, you mean mobile phone running the jk bms app?..if yes..then sometimes the phone goes out of range, as its a slightly big apartment built with brick and...
