Jip, and this what i like about this platform, you learn from other people. 15 even 20 years ago no one was in sort of game. It was the guys that stayed on farms that bought from the hand full of solar places and that time everyone learn from trail and error and DIY stuff. @Daniel Karstens drop your question here and scan the forum and see how other did there stuff.

Nope, you didn't. Just ignore mr "H" post on fb because his got a c#$%^ attitude and you not the only one he have picked on. That type of people I flat ignore and go on what i'm busy with. If you don't mind, I will post the pick you send me of the solar panel, the guys on the forum will give you more info and help.

@Jaco de Jongh let me give you a bit of light on Daniel story. He imported a pallet of 27 panels. He posted on Fb that he needed info what he need to complete his instillation , like what brand Inverter and batteries and all the stuff that will go with it. He added he wanted do it him self "DIY", and then the shooting of the FB keyboard hero's started because he stated DIY. You know how that part go's Jaco. One of the FB persons stated and comparing the specs of the panels that Daniel imported to T1 and T2 with Canadian panels. @Daniel Karstens post a image of the rear of the panel with specs and the front of the panel. They guys on the forum will help with the right stuff and @Jaco de Jongh is hands on with his stuff.

@DeepBass9 oooo yes, i'm definitely with you on that one with 12v lifespan compare to 2v cells. I got a price on the 3mil15s that is there starting range. It's 530amps per 2 v cell and in it's container "3 of the cells that give's you 6v" will be R10887 with all the cables and stuff that give with it. You need 8 of this containers cells so it will be R87096 . Like they state there, expecting life span of 5 years but can be more, and i have seen where they can last really long if you keep a hand on them. The one's Mike is using is the 2MLT25s "you can correct me there Mike if i'm wrong", they are 2x2v cells in a container and they are 1050 amps per cell. That's a lot of amps and KW :1050 x 48 / 1000 = 50.4kw Yes, in know you need to work cycle life and all that stuff but are you going to use all 50.4kw "25.2kw say if you need to split it in half for the 50% part", who is going to use all that power in the night in one shot if you run your home setup in the right condition/setup.

But yes, it is possible to run something that size with 12v batteries. This our setup that is running at Bellville Dept with 72 x 12v 230 victron super cycle batteries.

I'm with Mike on this. I'm in the market for new batteries and was weighting up my option between Lithium and 2 volt cells. Spoke this week with battery center to get a price on the Raylite ones. "they gave me a good price on 2v cells". It is expensive if you running a setup like 48v but the cycle life of this batteries are really good and can last years if you keep your hand on them and Ah are super high if you need supply demand. I have 2 family members that is farming in the middle of the Karoo and they use solar for many years now and are on 2v cells bank. What nice is about 2v cells is to, if you get a bad battery between 24x2v bank, you can take that battery out and still run on 23 till you replace the bad battery. there is some T'c and S's that go's with that.

Just want to clear it for you: not second hand, second life batteries. Nissan Eaton is doing it to. http://promotions.eaton.com/content/dam/beacon/residential/enduser/xstoragehomeb2b/brochures/xStorage_homeBrochure_update_June_2017.pdf

@GVC a bit of difference between them. You need to buy two of the Narada's to get to the same level of amps of the Revov batteries.

Ek het nou geloer, lyk of die revov tot 43.2v gaan maar ek dink 2 victrons is so bietjie swaar vir een stell batterye. What do you other guys say?

Thinus, ek dink 2 x 5kv Victron's is so bietjie swaar vir een stel 200amp 10.2kw battery setup. Wat als hardloop jy van die 2 inverters af?

@plonkster loer gou die foto wat ek bo gepost het. Daar is ook een wat aan die BMS gekoppel is. Ek sal kyk waar ek die post raak gesien het.

@Stanley and @plonkster will this unit maybe work for this? https://www.sonopsolar.co.za/product/byd-b-box-bmu/ https://www.victronenergy.com/live/battery_compatibility:byd_b-box-steps https://www.victronenergy.com/live/battery_compatibility:byd_b-box

There some regular post going up in cape town side and questions. We in a estate and I need to replace light saver globes on a regular base because it can't handle the power flax.

Jip, what I actually mean is is how bad our grid supply is. It's scary stuff. And my main question that i have asked on some forums and on FB, do's this impact out prepaid meters to?

@georgelza then you must come listen how my MLT inverter is going bos!!!! It runs contactors inside that connects and disconnects is from the grid. In the beginning i couldn't understand while the contactors keeps open and closing, till I start checking the logs, there i picked up that our Grid volts drop so low and the Hz going bos to. Same story over the weekend. Check your Hz part to.

Hahahahahah!! Hex is computer language. You can use this : http://www.unit-conversion.info/texttools/hexadecimal/ Dan sal jy die antwoord kry. Jare terug moes ons dit geleer en toets geskrywe het. Dit is ook al n paar jaar terug by gese.

OOOo yes @plonkster will give you more info on the Victron part.

Admin. Just change the heading Revov/BYD/Victron. @Thinus i spotted in BYD post with this setup and it's the same BMS that Rivov is using on there batteries. Best is to call Dawie of Revov. He will give you some info. Do you have some photos of your setup. I'm planning to get some Revov batteries for my setup to.

Thanks for your help there to Ingo. Nice about this forum, guys like you that have tested this stuff before.

Thanks Plonkster. I actually need to get a ESP8266 for another project to. Did a bit googling and found some info on the ESP8266 for battery monitoring.

Hahahaha!! think that will be a long think about. Way more advance that I have think 🙈

While I was busy checking around for stuff to build and program a Pi to run Amp clamp meters, this idea pop up in my mind to maybe check to build a Pi setup that can check individual batteries V in a battery setup where you run more then one battery in a setup. I think this will be something nice to have. Maybe someone on the forum that maybe have taken a shot in this direction?

Just check the battery level now and volts. A bit higher then the other so need to keep a eye on it. It looks like maybe. I guess my plans for buying batteries is getting closer.

@Mike can help with this in Cape town side.
