Your dude is Victron's chief developer. I will not reveal his name ![]() You can also find him on github under a i....k moniker All round great guy. Let Fangpusun write up their own firmware if they desire upgrades. There is actually a lot of effort that goes into all these things so the developer is entitled to protect his IP.

earthrealm: bro, i wouldn't jump to such conclusions yet if i were you. stand alone charge controllers are still way ahead of their hybrid siblings in terms of performance and features and those that value battery longevity will choose them over hybrids any day and anytime. personally, i don't think i would be singing such high praises of my recently sold off zenith batteries if my cc had been a hybrid. 2 Likes |

GeorgeD1: maybe, maybe not....i recently operated the mighty Sorotec hybrid inverter, and i am super pleased with its functions and data logging capability, i have also owned/used morning star CC {my first love], so i feel am in a better position to offer an unbiased comparism. For a frugal/thrifty person like me...its a no brainer putting down almost 300k for a 60amps morning star CC, whn such amount will buy me a 5.5kva 48v Sorotec hybrid inverter that can handle 4500w panels [ this implies an 80 or 90amps inbuilt CC] and accept 500Voc panel input. and inbuilt wifi capability and you still have small change sef. I believe you may have a rethink when you lay your hands on a well built hybrid inverter like sorotec/phoccos/easun/MPP etc.The world is marching on. standalone CCs in the coming years will be relegated to the background ---bookmark this. again, not everyone will buy into them, but i believe majority of people would... |

earthrealm:Victron bluesolar mppt and axpert mppt have been compared before on power forum and axpert came out on top. Although I don't know with their recent models whether that still holds. https://powerforum.co.za/topic/1429-axpert-mppt-vs-victron-mppt/ |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 2:02pm On Nov 06, 2020 |
The missing link may be that the Morningstar would still be chugging along steadily 10 to 15 years after commissioning whereas you would have taken your hybrid for maintenance at least twice in that same time window. I have installed a few Axpert types and even now the Steca variants and they all lack long term reliability or ruggedness. In one sentence, given normal usage and safe operating conditions, the Morningstar will almost certainly outlive the average hybrid. Also, may we debunk once and for all the myth of higher VoC = higher kwh yield and system efficiency? The hard truth is that the outcome depends on the specific application and operating parameters. In my experience, given 400v DC input at the PV, you should have an efficiency advantage if going AC coupled or giving AC output directly at 220v. It is a stretch to propose that it is more efficient to convert 400v DC to 48v DC nominal vs 150v DC to 48v DC nominal for battery charging and then invert the DC to AC 220v to run AC loads. We really need to match products with their intended use and not do one size fits all. It is key to look at costs and benefits over the total life cycle and considering as many variables as possible. earthrealm: 2 Likes |

Looking through the link and posts, the Axpert did not come out on top at all. Also the test methodology was flawed splitting into two separate battery banks - more conclusive results would have been had using thesame panels split into equal halves (done in the test) and maintaining thesame battery bank for the 2 SCCs with a large load to drain power from the batteries such that the two SCCs run in bulk charge mode all day (not done in the test).This is key as any current limiting during absorb and float charging will distort the results. Now excerpts from the posts - please tell us how the Axpert came out on top. Personal Notes on the tests : Apart from the one battery bank that took a bit more charge than the other I could not see any real apparent difference between the two SCC’s outputs. It was also noted that the Axpert’s data is not as refined as the Victron’s. The step pattern of the Axpert’s Amp feed indicates reporting of Amps in whole numbers oppose to Victron more accurate readings in decimals. There was also a small variation in voltage reported by the Axpert and this can either be ascribed to again the coarser scale of its voltage readings or an inability to perfectly maintain absorb or float. ... In my opinion there is no real difference between the two SCC’s outputs as the data confirms it. The only thing that I would like to see is how they would compare under a cloudy day where the SCC would need to adjust as clouds passes over the system One last comment, when you handle the Victron SCC you do feel that there is a big difference between the two units. The Victron feels solid and well built and I would say the Victron would be able to handle a lot more hammering than would the Axpert but considering the price tag I am not prepared to push either one of them but my money would definitely be on the Victron to be on top of that one ![]() The Victron gives you a host of options so that you could configure your system to be as automated as possible but it comes at a price. The Axpert is more of an off grid “Inverter/UPS with a SCC” that does not give you many options so you would need to build your own setup to make it work fairly well within a grid system. In my case I have a remote triggered switch on the Axpert that will switch to grid under certain.... So my summation is that on a sunny day there is no difference in output between an Axpert SCC and a Victron SCC. On a day with intermittent cloud the Victron may still have the upper hand. So is an Axpert a good piece of kit. "You betcha". It is comparable in some respects to top end kit and is ½ the price. Do Axperts inexplicably fail? The answer is yes to that question too. However, failure is not the exclusive domain of the Axpert ..... Namzy: 2 Likes |

NiyiOmoIyunade To sum it up. This is akin to comparing smf batteries. The usa made batteries like Deka and trojans retailing for 210k for 12v 200ah... Then the quanta going for 140k..... Then luminous, genus.... 120k. Then the 1st grade china batts.. going for 105k Then the 2nd tier china battery going for 85k. Which do you think, most people buy and why? My personal choice revolves round quanta and maybe luminous, am fairly certain only a small percentage buy the usa made batteries, you can ask the retailers as well... Same issh in lifepo4. How many people go for battleborns or pylontech?. We all know they are better, but majority will not put down cash for them..... Majority will go for felicity and the like, while others buy raw Lishen and Eve cells..... Everything na niche. How many units of latest range rover envogue are sold yearly...

earthrealm: Cool! Could you share more experience on that hybrid. What's the actual no load consumption? what's the conversion efficiency as your load increases (load at 500 and 1500w is though)?, How does it perform with lithium charging? (I guess you are using it with Lithium?) |
Re: Solar Energy, A Complement To FTA by samnaija: 9:02pm On Nov 06, 2020 |
earthrealm:I just bought this, you are very right. The fan makes a very loud blender like noise. As for hybrid taking over I think what is ruling nigerians is the cost implications of buying a separate inverter and charge controller. But in reality, if your hybrid as an issue with the inverter or charge controller and needs repair you are left with only batteries, start looking for a backup inverter and charge controller... |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 9:35pm On Nov 06, 2020 |
samnaija: I hear that a lot and makes me wonder; if the standalone CC dies, what's the use of the standalone inverter that is still alive? especially in a off-grid set-up. The main gist for me is that anyone that wants consistent power source should keep a copy of their hybrids or the standalones. May master J bless our hustle. 1 Like |

GeorgeD1: The great GeorgeD1. Always the one man batillion with opinions standing out from others. ![]() I won't disagree with your take on single CC versus hybrids for now sha, at least until hands on experience says otherwise. I have yet to try out an hybrid so I can't claim any expertise on its performance or debate a reasonable comparison. |
Re: Solar Energy, A Complement To FTA by samnaija: 4:02am On Nov 07, 2020 |
ojeysky: For standalone, If your cc dies in an off grid situation, which we all know you must have a gen for backup, you will still survive with your inverter . Besides all I have to find is a backup up cc and life goes on.(less expenses). But in hybrid, cc get yawa you withdraw the whole system how do you want to operate with batteries only. Ok you get back up let me guess another hybrid (more expenses), or a standalone cc and stand alone inverter (more expense). Any how you look at it, it also boils down how the devices are built, I have used my episolar standalone for 6 yrs no yawa, but within that period I have repaired and changed my inverter so many times no brainier......

Re: Solar Energy, A Complement To FTA by ceaser: 4:34am On Nov 07, 2020 |
ojeysky: I will align with him and with you as well. In his case, for some the cost implication of getting a stop gap hybrid replacement while you are getting the main hybrid repaired will be more expensive than getting a standalone CC or standalone inverter. Remember that in most cases, the stop gaps will usually be smaller capacities than the main system. People may have a spare 1.5kva inverter benched for days when their main 3kva may need to be repaired. For those that can afford it as an emergency, getting a hybrid for stop gap may not be an onerous challenge. I remember you using the cheaper, less capacity and smaller VoC Felicity while you awaited the replacement board for the MPP. The Felicity is much cheaper than the MPP but definitely more expensive than a standalone that may be used as a stop gap. Also, high VoC and remote data logging becoming standard features of most affordable hybrids is a valid threat to the desirability of standalone SCCs, at least to me. That is me assuming that I am unaware of any standalone product with high VoC capability. However, I'll also posit that the more parts of stand alone systems calls for more points of failures but easier replacements of the failed parts wherease the integrated feature of the hybrid means less failure points but potentially challenging replacement when you need to. You may be required to change whole boards or the whole system in such scenarios. |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 6:22am On Nov 07, 2020 |
samnaija: A complete off-grid will not have a Gen as that is a backup already, I was referring to such situation. Nevertheless we are in agreement on relative replacement cost but as you said it all depends on the equipment to be replaced, a powermr CC will be easier to replace (cost wise) than a morning Star or victron. ceaser: Right but it's an option I don't think I will want to take again in future, a plug and play will be better, even if it's a lower capacity. Having to rewire my panels then was a little bit easier but won't be what I want to do with my current setup.
In my case, I could have just gotten the MPP Board as a replacement backup at similar or less than the price of a felicity and save myself the stress of having to rewire my panels. That said, on a lighter note, the thought of buying a replacement part for a future scenario thereby locking down funds is what I also need to overcome ![]() GeorgeD1: The "hybrid" can't be a battery spoiler my Oga ![]() |

ojeysky: @bolded is one error I won't be forgiving myself of anytime soon. Few weeks back, the sad reality of having to buy a complete gate opener stared me right in the face. Thank fully it was only a blown fuse that when replaced got things working again. I contacted the seller's store in hope of buying a board to keep but realised that the product itself is not even listed in his store again, nor in any store for that matter. |

I have used both hybrid and standalone systems now for about 6years. My observations: 1) Hybrids easier to procure and deploy as per cost and ease of initiating newbies to RE. 2) Most hybrids seems to be having relationship issues with Litium batteries ( charging profile mainly) also estimating the SOC seems to be a challenge. 3) In a stand alone system if your inverter is faulty then your system is down same as in Hybrid situation- it's same same. Moreover, CCs aspect of my hybrids has never given me issues only the inverter part and I could believe that it's due to the fact that it's the one doing the heaviest work 4) Hybrids do not seem to like low grid voltages for charging. No issue with the bypass mode but gets stressed if also used for charging ( one of mine actually caught fire , real �) , could not charge anymore yet continued to invert for years afterwards.
