@EtienneWesRand Just post a photo of the add or the battery. If' it's Li-on tech units i think it is, stay away, it's stolen cell tower units. In the battery section someone ask for settings and on 4x4 forum to where we spotted is.

So over the weekend I got my Lifepo4 setup up and running properly and moved the batteries to it's enclosure. Still some stuff to do around the unit like running the DC cables in black sleeve and crimp shorter cables from the battery to the breaker and used the old longer cable for the 2nd unit i want to build. So far the Lifepo4's perform really good and still tweaking my settings and stuff.

@JJS run 9×335w . I'm running mine like this. 3s 3p. Your volts will between 120 and 130v from the pannels to the mppt. In the rite weather condition you will get it close to max out. You will see in my photo i did a test to see how hard i can pull a load and it nearly max out die mppt. The volts from the battery side just to start to drop en volts from the pannels drop from 121v to 100.4v.

@NigelL at what place did you buy the black glands and black sleeving? They look really good.

You Can get copper plate and bars and off cuts from this guys https://www.copalcor.co.za/ They are in Stikland. I had some left overs when waterjet some copper shim rings for my vw aircooled turbo motor that i used for my Lifepo4's. They got of cuts at at back and they work at KG/R.

Soooo i'm not the only one!! sjoe!!! Days just after i installed my pannels , this 2 gray rats with wings i called them, pitch up. One morning I host them lekker down with water, but the just keep coming back at night time. I had the same plan that Fuenkli did so I just need to do it. It's like the program/born to do this. My 17 year old cat is lazy to go catch them.

@GVC post some photos how the unit looks like inside. @Bain Viljoen new bms units even got his brand name on it now😁

Big PPPPFFFFFF and smoke!!! hehehehe

You will see one some of the screen shots shows capacity 60AH , then i founded the lifepo4 setting on the BMS and all the settings was adjusted correctly and batteries was fully charge at 119.1AH / 100% SOC.

@hennie65. Nope was super easy actually. I did a bit google'ing and found the APK app and downloaded it. I'm still waiting for my balancers to arrive because the post take forever but the BMS got it's own setup built in that impressed me. It's got Auto Balance when no charging going in, then it's got Cell Difference Balance that kicks in when charging under 10 amps, this kicks in to when one cell hits the 3.6v charge limit that you can set to in the app. You can do a lot of adjustments in the app. it's got a Charge MOS and Discharge MOS, so when it hits max volts it switch of the charge part but keep the Discharge part open. It's got it's own coulomb meter. There still a lot of adjustment i need to and get the rite spot for volts and charging and stuff. Will post some photos now. I still need to transfer the setup in it's cabinet.

At @JJS Jip!!! they took there time!!!! Will import next time with Scottshipping to get it faster. Did all my crimping Friday night and got the battery connected Saturday to the Inverter and MPPT. Did some a bit of maths and programming of the units and settings, start charging and doing adjustment till i found the sweet spot for charging from the mppt. By yesterday morning I got most of the stuff sorted on the BMS and batteries was full charge. The screen works lekker with some nice info with the setup but the blue tooth part is the best. I can sit any place in my house and check what happening and adjust the settings on the battery and check all the cells as it charge and working. Had my first test last night, batteries took over from where MPPT can't supply anymore and this morning at 5 pm it was at 66% at 78.126AH, and it was on 119.1AH when it took over from the mppt. My wife was using her hair dryer and we used the microwave and 2 Led tv's where running and my network system and cctv system and leds lights and fridge and laptop standing on till this morning. Planning to build another second setup. Will post photos later of this setup.

JIP!!!!!!!!!!!!!!!!!!!! stay away!! they selling stolen MTN units. One guy on a other forum bought a set and he didn't know. they removed all the info on the unit. Check the Li-ion Tech post just lover on this forum.

My BMS have arrived yesterday. Will start crimping tonight and see if i can get it up and running.

Hey guys, i'm looking for a second hand Microcare or Setsolar 60A mppt. If you got one or have one that you want to sell, let me know, thanks.

And i'm with plonkster there, with quality products come's a price. I have paid some school fees to learn this.

@plonkster for time they were selling that chines stuff " we spoke about it" day later "S" site was off for a time, then it came back, with victron stuff on it and between it with some 芳普森 .

Hehehe. They doing there rounds, good luck for the person that entering the code to do the register for update. Slow death of the BMV then. Setsolar actually sell them to.

@Krokkedil you can actually speak to Bain, the person that is importing the cells. His got some buyers that using in there inverters and camping stuff and a farmer that's using it on his farm.

@jjs I'm still bussy waiting for my BMS. SaPO is taking there time to send it from JHB to CPT. Waiting patiently for it. Hope to have it in this 2 weeks.

On what lithium / lifepo4 setup are you using them @barry8212 post some photos please. I was eyeing them for my setup but they cost a arm and an legs price if you need to import them.

Hahahaha. Jip, free all the way downhill. I think Mike Thorne on the forum or here https://www.facebook.com/groups/ThorneSolar/ will be your best bet to help you in cape town side. He knows his way arround this stuff.

We will not talk about the price of the fancy balancers. Eina!!!!

@ebrsa i know Will. I'm on his forum following all the stuff there. On the batteries, the person that i bought mine from in SA imports them from an manufacture and tested. He tested them before sending them off to me and he founded that they actually takes more then 120 amps when charging. They have black tape over so cant see whats on top. On the BMS part. I didn't like the Daly one's because the don't have bluetooth or coms and they only have fix settings, i want to change stuff on mine. On the temp stuff, we don't get snow weather or go - temp like in the states side. The one i took is this one ZAR 749.72 25%OFF | Smart Bluetooth 7S-20S CELL Lifepo4 li-ion Battery protection Board BMS 400A 320A 300A 100A 80A PHONE APP 8S 10S 12S 13S 14S 16S https://s.click.aliexpress.com/e/DVWllBBQb Will did a test on this one and was really impress with it. On the extra balancer i took was because the bms units only bleeds low m/amps like 100ma, thats to low for me and will take really long to get your batteries level out. The balancers i took can run at 1.5amps and is top end ballancers. Active ballancers is super expensive when you buy the propper DIY one's. I did a lot of reading and info about bms and stuff. So this setup will be my test setup to see how it runs and performs. There is already a 48v diy setup running on a Axpert 5kv and so far it's running good.

Ahaaa. Ok. Around the corner of me. I'm in Sonkring.

The bms with screen and bluetooth was $93.00 with shipping on BlackFriday, that landed in SA last week so just waiting to arrive in Cape Town side, top end Balancers was $16.60. Waiting for that. ACDC enclosure was R1250 for 600x600x270. Rack i build out of steel that i had. Going to add welding speed connectors to make it easy to connect and disconnecting the unit. The copper bars i made out of old 3mm copper plate i had from a othet project. My solar instellation not finish in this photo, waiting for stuff that i order and stuff that bought on holliday that i will add when I'm back home. Planning to build one more or two if this one works out nicely.
