NoMoreTrolling: wow, most cc cant handle the exceesive juice coming from the panels..if u disconnect the cc to batt connection..leaving the panel to cc connection on. its common knowledge here naaau, only a few cc makes can survive this error, my epsolar 60amp survived it...but i wudnt test fate next time, i may not be so fortunate whats the make of urs? |

earthrealm: men, i don't even know the name sef. like "Yamako" or some shh like that. Sigh, are you for real though? something was telling me to wait till the sun goes down, but i had to disobey my gutt. when the installer installed it, he didn't put a dc breaker between the solar panels and the charge controller. it would have been so easy to switch the solar off, if i had that. i didn't know it was common knowledge here, sigh, should have been following this thread more closely. wish i could afford another mppt at this time, like your EP, but, maaaan, sigh, wtf is all this bad luck though I will just have to pick up a cheap pwm in the mean time. Quick question, whenever you install your new battery bank, do you charge the batteries individually first before you series/parallel them I'm thinking maybe these ones where imbalanced from the start. |
Re: Solar Energy, A Complement To FTA by DMerciful(m): 11:37am On May 13, 2018 |
Wrong practice to disconnect battery when panels are still connected to cc, the cc will most likely fail. I solved this problem by using a double pole breaker with battery-cc positive going tru one pole while cc-panel positive going tru d other pole that way anytime you trip the battery breaker, everything goes off. What is your charge controller make? earthrealm: 2 Likes |
Re: Solar Energy, A Complement To FTA by hardywaltz(m): 12:21pm On May 13, 2018 |
NoMoreTrolling: The right sequence is: Turn of the breaker from the pv to the Charge controller which will make ur CC go into sleep mode Then turn off the breaker from ur Batteries to ur CC before disconnecting. Same with powering up the system U turn on the breaker between the battery bank and CC to power up the CC and then after a while u turn in the breaker from the pv to the cc 5 Likes |

pranil: thanks for your response pranil. when I'm on my pc ill give a detailed reply. bt for now >yes, fronius is on out output of victron >ESS and pv assist values are correctly imputed. atleast the system was working fine for some months before it started this behaviour >victron inverter is 10kva each, all quattro |
Re: Solar Energy, A Complement To FTA by Trippledots(m): 12:31pm On May 13, 2018 |
hardywaltz: very true.... a guy got a smartsolar burnt by turning off battery breaker and turning it on with pv connected all the while... |

Re: Solar Energy, A Complement To FTA by earthrealm(m): 12:54pm On May 13, 2018 |
NoMoreTrolling: hmmm, are you a diy person?... ur choice of cc is poor, not a common make, and based on that and the error you made that fried the cc, i may extrapolate and infer that you are not much knowledbagle about RE and may hv fired ur batts ignorantly due to wrong cc/setting. so b4 you accuse ur batt seller of selling you substandard batts, ensure the fault isnt from you. yeah, it is good is to charge each of them individually fully first. though its not a sure protection from batteries getting mismatched during use. ur best option is installing a battery balancer. @trippledots : most 2v 500ah/800ah/1000ah batts are gel quanta/long are the common agm batts the batt type is usually written on the body of the batt 4 Likes |
Re: Solar Energy, A Complement To FTA by NoMoreTrolling: 2:02pm On May 13, 2018 |
earthrealm: well the choice of cc was made my the installer, we just paid for the whole system, instead of paying for parts, so we had to deal with what he got. As for experience, well, this stuff is all pretty basic. well i guess that sounds, weird, being that I made this cc error, but the more I think about it, the less sense it makes. When the batteries are full, the charge controller throttles charging current all the way down to zero, even in full sun, so why would it fry when the battery is disconnected isn't that open circuit similar to no current on a full battery As for the battery, well the charging characteristics were met pretty closely. The CC would charge up to 56v daily, same with the inverter. So it was never overcharged. we just started losing capacity rapidly. I mean we have 2,000 watts of solar, electricity from 10-7a.m, 4 200ah batteries and just running 500 watts load continuous. I feel under these circumstances, that the battery should have lasted for years. |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 2:38pm On May 13, 2018 |
NoMoreTrolling: check the battery for the cycle and standby voltages, then compare same with ur inverter and cc charging voltage setpoints. ur inverter..does it have batt type selector switch? if yes..am assuming you selected gel batts, did the voltage setpoints jive with the oem batt sepoints?...same goes for your charge conroller |
Re: Solar Energy, A Complement To FTA by DMerciful(m): 3:05pm On May 13, 2018 |
48v battery system fails this way unless you have multiple string of 48v so that each string might be doing 5A else imbalance sets in even with balancers.. My reco is to limit our systems to 12v or 24v unless you have enuf money for multiple battery strings. If you have money go lithium and have peace of mind NoMoreTrolling: |
Re: Solar Energy, A Complement To FTA by makavele: 3:08pm On May 13, 2018 |
NoMoreTrolling: Should have disconnected solar first. Your CC is fried and will not regulate voltage again Disconnect from battery else battery will roast too 1 Like |

Please which brand of solar panel can be regarded as the best coz it's seems most of not all the panels are made in China. I'm asking for a colleague who wants to buy but is confused on the right choice. |
Re: Solar Energy, A Complement To FTA by NoMoreTrolling: 3:37pm On May 13, 2018 |
earthrealm: The inverter has no setpoint options Not sure about the charge controller, but funny enough, the battery voltage never goes beyond 56v, not that I've seen, even though the battery cycle voltage states 14.4-15v and float of around 13.6-13.8v. So i guess it's expensive inverters that have setpoints We also have a 24v prag inverter and that one doesn't have setpoints either, the only settings i see on the prag are charging current options, 10A/20A, but that one takes the batteries to as high as 14.8 per battery, before settling back to float, which this 48v (soccer) inverter has never done. Guess I need to call the installer back? This is just a sad day men, but, who is alive today without problems? I will have to face them this week. |
Re: Solar Energy, A Complement To FTA by NoMoreTrolling: 3:45pm On May 13, 2018 |
DMerciful: but 10amps on a 12v 200ah battery should be very low though, don't you think? 5 amps is like super small per 200ah battery, thats like 60 watts per battery, 240 watts for the 48v system. That draw is too small for our application and batteries are so expensive and not even trust worthy for me to think about having 8 batteries in a single bank. I would rather have 2 inverters, with 4 batteries each to minimize bank failure, since people always say that you have to replace the whole bank if one goes bad. Honestly, I hate batteries right now men according to the chart below, i should be able to get around 10 hours at 10amps(0.05c) before the battery hits 50% dod, but real life has been way way different. That 10 hours would be more than enough for our application if only it applied to real life.

makavele: I should have come here to ask first before thinking this was a quick and simple procedure, sigh. I disconnected the negative terminal of the charge controller cable from the battery and wrapped it up, the positive is still on there though, but i don't think that's an issue. |

Re: Solar Energy, A Complement To FTA by earthrealm(m): 7:20pm On May 13, 2018 |
NoMoreTrolling: mordern inverters usually have adjustable batt type selector switch, with accompanying voltage setpoints, its only old inverters that dont hv such, my 1.5kva luminous does hv, but am not bothered cos am using it in an offgrid enviroment, on fla batts. where phcn comes once in months what is your primary charging source?..solar or phcn?...the setpoint of the cc is user editable, and done on the cc software, there are so many unknowns in your issue, to be able to pinpoint the cause of failure. discuss with ur installer and chart a way forward. upload a pic of your battery lets us see, is it the 2v 500ah type?. this shud be a guide to all newbiew..try to avoid buying inverters without batt type selector switch/clearly defined voltage setpoints,...and request for agm, not gel |

Re: Solar Energy, A Complement To FTA by NoMoreTrolling: 8:19pm On May 13, 2018 |
earthrealm: lol, for real bro, i really do feel like a newbie, even though I am an electrical engineer. really goes to show how valuable hands-on EXPERIENCE is in any subject matter, as opposed to the limited theoretical scenarios one envisions. my primary charging source is gen/solar. "phcn" can't really be considered, cause it isn't a constant. it's just sad bro, cause we have light every single day from 10p.m-7a.m with the gen. The solar is suppose to take over from 7a.m-10p.m and it's beyond depressing that 2000watts of solar and 4 12v 200ah batteries can't accomplish that on 500 watts of load. Guess the inverter might also be an issue though as honestly, i have never seen it charge beyond 13.8v. just seems like wasted money all around, well, i guess except for the solar panels please dude, i need some more advice before you go to sleep, I can send you some orijin bro. so now, I went back and reconnected the charge controller negative terminal to the battery and the controller came on and wasn't stuck, like it was when it was sending straight vmp to my battery without modulation. do you think it has been fixed miracles still happen na, abi i plan on leaving it like this, then checking the battery voltage from sunrise - 7;30a.m before i have to leave my house, but the pv voltage might not be at its max by then. God help me that i don't come back to a burnt house. when the controller failed and was sending vmp (when i disconnected the controller from the batteries without disconnecting the solar input from the controller), the screen of the controller was just stuck, like displaying all numbers, i couldn't click on anything at all, couldn't see battery voltage, pv voltage... nothing. will post the batteries later |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 9:12pm On May 13, 2018 |
@nomoretrolling, yeah, u may be fortunate, mine the +ve cable pulled out from the crimping, and was in this state for about 3wks, b4 i was able to travel to troubleshoot, when they complained, so miracles can still happen. what voltage was it sending to the batt?. best u stay till sunup..9am and confirm the cc is ok, b4 leaving the house, unless u got folks at home u need to go tru the manual of ur cc, and confirm it has a batt selector type, and that its on gel, and the gel voltage setpoints corresponds to what is written on the batt. that ur cc is unknown..i dont trust it 1 bit. if you survive this..best change it to a known/reliable make, like epsolar/fangpusun etc since phcn is nonexistent, and gen is ur normal charging source. am leaning towards the damage being caused by the cc, ie if the batts werent defective from the start |

[quote author=chimaaba22 post=67538506][/quote] Is this precious forum turning to a rant group pls?If I may ask ,if this forum is for personal opinion and knowledge sharing, why cant few people drop experiences and leave in peace instead personal attacks which is uncalled for. Why should unnecessary threats be issued on a knowledgeable forum like this. From a feminine view although I stand to be corrected,I saw nothing wrong in what the op you threatened for notin posted on a said brand as he has no particular interest neither was he marketing anything as claimed by you and you do not feed him a bit.I might be new on the forum but i came across Mr Richmond posting pics of an inverter which got burnt then and we all learnt.. You brag as a man about pulling a fellow man with dignity down On same open forum he has been known for long.He only quoted Mr Eartrealm as extrapolated in picture below because they both have used epsolar mppt if you duely follow the forum. You would have been diplomatic in your own comment if you had anything to type or remain mute for sanity sake,I do not know you but be wise pls 6 Likes 2 Shares
