Topmost11: ![]() ![]() Its what it is naaah 95mm cable is what is required, u have 6mm. That shud show you the gross error in your cable sizing.....as i said earlier. Mppt is best for such length..4s or 3s..depending on max Voc of your CC You are supzd to be getting 30amps to 50amps as you can see....but you are only getting 11a..or max 18a i bet |

adrusa:I have installed a few. Your best bet is to get an earlier version of the app. The newer versions will request an update (which might brick your device). The settings provided by the rotary switch should suffice for most uses. Avoid firmware updates unless absolutely required for the functionality you require. I've been burnt twice so I am somewhat experienced now. You could PM me if you run into issues with the earlier apps though I foresee none. 1 Like 1 Share |

NiyiOmoIyunade:The Fangpusun, while a good product (like the Victron prototype), isn't of the same specs. Stellar performance, yes but the algorithm is a bit different in implementation and that minimal difference might cause enough drift to wreck your battery bank. I advise against it. Consider it similar to mixing batteries of same capacity but different makes. Especially as you're heavily invested in Morningstar already. What's one unit more? PS: Victron units are absurdly durable and will tolerate ridiculous levels of abuse, as bigrovar previously stated. |

adrusa:I believe one won't really describe it as a design flaw. Literally all Chinese CC have that problem (I wouldn't know of Fangpusun clones of Outback and Victron). Of the common CC, it would appear Victron, Midnite and Outback have found ways to mitigate that problem. 1 Like |

Re: Solar Energy, A Complement To FTA by hancock(m): 8:28pm On Jan 01, 2020 |
earthrealm: 95mm2 is the square area of the cable and not the diameter So a 10mm diameter cable will have an area of (3.14x5x5=78.5mm2) while a 12mm diameter cable will have an area of (3.14x6x6=113.04mm2) etc..... I believe a 10mm cable should suffice for the tax |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 8:46pm On Jan 01, 2020 |
hancock:wellll..... cables are usually sold by mm2 not diameter, you can confirm this by looking at the marking of any cable you have. you believe wrong bro................... ![]() ![]() |
Re: Solar Energy, A Complement To FTA by Saipro(m): 8:46pm On Jan 01, 2020 |
hancock:10mm cable is actually 10mm². 95mm² cable is real and quite thick (I use it on the +ve input to my Victron inverter). Consider that 300mm² cables exist |

Re: Solar Energy, A Complement To FTA by hancock(m): 9:25pm On Jan 01, 2020 |
earthrealm: On the contrary, I get the point. I am just wondering why are cables sold as 10mm/10mm2 or 50mm/50mm2 in this part of the world ? What does the 10mm represent and what does the 10mm2 also represent? Clearly they don’t compliment each other if you consider the diameter and area logic Don’t mind me , this is my OCD in mathematics kicking in ![]() |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 9:57pm On Jan 01, 2020 |
MM and MM Squared are metric measurements while AWG are US measurements - you will always find a US AWG size that is approximately equal to a given metric size e.g 6AWG cable is approximately 16mm-squared. What we colloquially call MM here is actually the surface area measurement (mm squared). Surface area is what matters because apparently electricity is thought to flow on the outside surface of a conductor, so all things being equal, larger surface area means abillity to carry more electric current with minimal resistance and heat losses. The MM is the diameter of the bare conductor which one could ascertain with a calipre or other measurement. These are my thoughts - based on a long history of purchases from North America and some electrical experience - I could be wrong as I never subjected this to rigour. Just took the knowledge 'as is' On a lighter note I just purchased a set of marine grade copper ring terminal lugs (what you crimp on battery cable) for a project - Amazon lists them as 6AWG 5/16" eyelet ring terminals but the metric on the body is SC25-8 meaning it can take a 25mm2 cable crimped onto the lug and an M8 bolt through the ring eyelet to screw down to your battery post or bus bar. Confusing eh? But one gets the hang of it eventually. hancock: 1 Like |

Re: Solar Energy, A Complement To FTA by Saipro(m): 10:51pm On Jan 01, 2020 |
earthrealm:No ignorance there; you were operating well within recognised/acceptable limits (distance of the cable run plays a huge role in determining the cable size chosen). Perhaps not cost effective but fewer headaches on the long run. So long as your breaker/fuse can protect your cable/equipment, you're fine. Breakers/fuses are primarily for protection of the cable (in our own RE case). In the instance of considerably oversizing the cable to avoid overheating/fire issues, you'll size your breakers/fuses to the lowest value that would protect your equipment while avoiding nuisance tripping. [s]If you're certain of your connections and in a good mood, you could go a bit higher though that practice is unsafe and highly discouraged, even for pros[/s]. Have safety gloves and a fire extinguisher handy at all times. |
Re: Solar Energy, A Complement To FTA by Saipro(m): 11:00pm On Jan 01, 2020 |
adrusa:My pleasure hancock:The mm unit suffix is presumed to be the same (and often used interchangeably) with the mm2. Consider it the shorthand form. earthrealm:Interstingly, just about twice the thickness of the 50mm2 cable though quite pricey as you've deduced. |

NiyiOmoIyunade:Always a pleasure to read from you. In my opinion, both battery types require some babysitting and monitoring. The energy density and corrosion issues are what lead has going against it. Maybe energy losses (as heat) while charging. Issues surge and DoD? Sizing the bank appropriately deftly caters to this. My US Battery banks for clients last an average of 3 - 4 years despite abuse in every single case. I still see no reason to discard lead chemistry. And I have LiFePo4 batteries with irregular use which I have been charting for many years now. While lithium is fun to use, it is not what I need. My appliances and energy requirements have been so fine tuned that surprises won't knock me off balance and redundancies would absorb all but the most unforeseen catastrophic event - and there's the backup LiFePO4 to ward that off (the lithiums have refused to die even with infrequent charging after 80% discharge). I suspect lithium might be the solution of the near future, if not overtaken by some other chemistry or energy storage device. Let everyone believe what they would but choose wisely what would suit your needs. Ones application-specific requirements might not be the trending choice. |
Re: Solar Energy, A Complement To FTA by Saipro(m): 12:37am On Jan 02, 2020 |
funshyboi:... as soon as the batteries are reasonably "full", the battery voltage would rise rapidly to match that of the PV output. Unless the incoming current (after deducting loads and losses) is really small compared to battery capacity (typically 4% or less). Given those conditions being met, you're likely to damage your battery from undercharging. As you can see, either way is a lose-lose. Slip in a cheap but functional CC and you'll minimise the possibility of a premature battery death or worse, a fire. |

Re: Solar Energy, A Complement To FTA by Topmost11(m): 5:48am On Jan 02, 2020 |
earthrealm: Lol. You have a great sense of humour. Any cable that is above 1000 per meter is too expensive for my needs. From my research, cables are in mm² or awg(american wire guage). I was told 10mm² is ok for my needs so I went out looking for 10mm². I had to settle for 6mm² at the end due to urgency of the situation. Sellers confuse by telling you 10awg is 10mm². I almost fell for it but when I told him I wanted 10mm² and not 10awg, he confessed he has only 6mm² which he wanted to push to me as 10mm² since it has 10awg written on it. So once you see 10 you believe it means 10mm² |
Re: Solar Energy, A Complement To FTA by Topmost11(m): 6:04am On Jan 02, 2020 |
hancock: Cables are in mm² or awg. We in this part mention mm because we are more comfortable with that than mm². As you rightly said mm is diameter and mm² is area so can't be same thing. We are the ones causing confusion for ourselves assisted by cable sellers. No cable will have mm on it; what you'll see printed on cables is mm² and/or awg. 2 Likes |
