@JUO and other Fangpusun/Victron Clone users here. I just installed a 150/70 Tr and it is asking for firmware update before I can use the victron connect on it. Can I go ahead and update? Is it safe at this time? Thank you.

Isn't anyone using Fangpusun/Victron Clone here? Please help a brother.

I got 3/0 awg and 95mm². What is that in mm

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

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.

Well said Oga GeorgeD
For this very reason I have 3 MorningStar MPPT 60a units and as I take my array to 15kw I have been struggling whether to purchase a Fangpusun as the 4th unit or stick with MorningStar. Very likely I will stick with MorningStar even though it costs twice the price of a similar Fangpusun unit.

My experience when I snagged up a Victron Quattro 8Kva was similar, I moved from a place of wondering whether my 6kw Red VilPower Star would randomly pack up one day (has a very failure prone control board) to a place of quiet confidence and assurance with Victron.

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.

Morningstar CC has a fatal weakness that kept me away from it. If the battery disconnects from the CC in the afternoon when there is sun, or if you mistakenly connect the PV before you connect the battery, the CC will catch fire and be damaged. I will never touch a MorningStar, ever.

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.

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

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

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 cheesy

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.

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.

The mm unit suffix is presumed to be the same (and often used interchangeably) with the mm². Consider it the shorthand form.

Interstingly, just about twice the thickness of the 50mm² cable though quite pricey as you've deduced.

I recommend searching through this forum for the answers provided. Summary: while some might swear by them, lack of empirical evidence makes their proven usefulness dodgy. Many believe they're nothing but snake oil. I believe in desulphators (a select few brands with track records).

One of the problems I have come to see with the Lithium vs Lead Acid comparison is comparing unlike terms - comparing a premium or above average Lithium battery like BYD or PylonTech vs basic lead acid batteries.
....
By then also, I will have 5 years + of field experience from Ogas Pranil, DapSyra and Hancock to support my decision.

Interestingly Felicity have a Lithium offering that is priced pretty juicily and backed up by good support. Those are the kind one could take a risk on as the entry price is within the reach of us common men.

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.

funshyboi:

I was told the connection won't need a charge controller as the current the panels will generate won't be to much for the battery. Stand to be corrected tho

... 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.

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

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.
