Perhaps there is a solution out there, I haven't tried to find a solution. Up until others shared there experiences about it on this thread, I assumed It was a problem unique to my particular unit. earthrealm: |

Saipro: lolz bro, my setup is still small in comparison to some others. I like to think of it as a work in progress. |
Re: Solar Energy, A Complement To FTA by NoMoreTrolling: 1:45pm On Apr 20, 2019 |
Saipro: I think it really depends on the brand of battery as you guys have stated. Trojans would obviously be better than our previous GACIA, EPSOLAR and Mercury batteries. Though I really had high hopes for the Mercury, but maybe it was fake, who knows. I guess were they are bought from is also a factor. |

GeorgeD1: Wow, soooooooo much solar power, my goodness!!! I wonder if you still have MAINS electricity connected to your house, or are running solar/gen 24/7. |

Im2Busy2Bother: the plan to oversize was a deliberate attempt to beat south-south constantly cloudy weather. thanks to zeestone for helping out with the first half of my array - 24 units solarworld. I was quite impressed with their professionalism. juo and his team of experts came on board for the second half - 24 units canadian solar which was supplied at wholesale price by gennex early last year. in all, a great team I was privileged to have crossed path with. |

Installation almost complete, testing now! Voltage drops, voltage drops everywhere. Well all I can do is thank God. I checked the bmv and saw a max voltage of 60v to the battery. I was wondering how that could be possible when the inverter and charge controller were set for 14.2 volts. There is a huge difference in voltage reading between the charge controller and actual battery posts. For example, battery posts voltage could be 55.4v while controller voltage is 53V. So when the charge controller was set at 14.2, which is 56.8 absorb for a 48v system, the battery voltage would have been around 60v in accordance with the bmv. SO SCARY!! The batteries do have internal protection circuits though, so it would have shut down the battery if that situation had gone on longer. I'm happy I caught it in time and I have made compensations to the controller setpoints. The batteries now charge at around 13.8V with solar and 14.4 with the inverter. Funny enough, the installer never caught this and according to him, it would have been job done and one year later, the batteries would have been severely overcharged. Two heads are better than one though, cause there are somethings he knew that I didn't know. We are using 6 AWG cable between the charge controller and the battery, running a max so far of about 20amps. Anyway I guess the morale of the story is to check monitor actual battery voltage THROUGH OUT a charge cycle with the inverter and controller to make sure the peaks are within battery specs during initial installation. You don't want to trust those displays, get out your multimeter. I have seen pics of some guys systems here were they leave an el cheapo digital voltmeter permanently attached to each battery. I truly believe that is the way to go for every one with a solar battery.

Next is changing out the DC wiring from 6AWG to 4/0AWG wiring for higher amp draw from these batteries.

Very impressive from the battery thus far and the voltage was still very steady even after using 75ah of the available 100ah. I didn't want to push the discharge all the way down to 100ah, I got scared

earthrealm: Seems this "Gennex" inverter is a rebranded inverter. Found a similar generic type, check this link to see if they are indeed similar. http://www.solarwholesale.co.za/Axpert%20MKS-MKS%20PLUS%201-5KVA%20Manual%20on%2020140306.pdf 1 Like |

NoMoreTrolling:MPP Solar Gennex and many others purchase inverters from Voltronic Power.Voltronic is publicly traded. You can sell your own inverters with your name and the will make it for you 1 Like |

chris81964:CC: nomoretrolling ok, tot as much, cos even ipower has similar infrastructure, have seen all the manuals, but none for gennex, theyare all same then. i am trying to troubleshoot a setup of 8 batts and 1800w panels, that barely lasts 1hr on 450w load .. terrible thinking of recommending 8 x 6v 400ah agm batts to owner for replacement, ie after finding the root cause of the catastrophic failure... instead of 8 x 12v 200ah quanta batts, wetin una think? |

Re: Solar Energy, A Complement To FTA by chris81964(m): 2:34am On Apr 22, 2019 |
earthrealm:How old are the batteries/ What voltage do your charge them to? What is the LBCO set to on the inverter? If all these are good revisit your wiring and then check the individual battery voltage to see if you have a bad one? Is the inverter controller a pwm or mppt? How is it wired? Are you in the pwm or mppt voltage range? |

I have been having same issue with my 5kva 48v installation. I notice that after about a month of use, one battery of the the 4 batteries I use always get bad (low reading below 10v). I rotate them, replace with a good battery reading 13v and after a month, the same battery position still reads below 10v. How can I overcome this please... NB: I use full river 12v-200AH batteries 4 in series. I use a 4kw magnum inverter. Thanks |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 3:40am On Apr 22, 2019 |
chris81964: Its a gennex 5kva 48v with 80amps mppt inbuilt cc. Thats why i was looking for the manual so i could understand the settings/config . Would keep the house updated..am certain more than 1 batt is bad for it not to carry 450w load for 1hr. Batts are a mess. First 4 is about 2yrs old.2nd 4 is about 5months old..wonder who advised them to mix such |
Re: Solar Energy, A Complement To FTA by mctfopt: 5:50am On Apr 22, 2019 |
earthrealm: Judging by the load, I'd recommend they increase the number of solar panels. Also, as you already know, mixing old and new batteries will mostly not end well. As the batteries stand, I think some batteries had failed which had led to the abysmal performance. They would have been better off with just the four new batteries alone than those new ones been in parallel with the older failing (or failed) batteries. |

CASHCOW247: Ehats the make of your inverter?..is it luminous?..or any of these old gen inverters the old 1.4kva luminous had this notorious problem too. try installing a batt balancer to see if it helps 1 Like |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 10:12am On Apr 22, 2019 |
mctfopt: yeah, thats part of the plan, am even likely gonna suggest a standalone CC, as i saw 1.23kw instantenous harvest from the 1800w array on a cloudy dull day!!!..we all know this is impossible. will do further extensive checks, now that i have the axpert manual. want to be sure of what exactly killed the bank, so its eliminated b4 laying down cash for new batts, cos even with mixing old and new batts, i dont think the failure should hv been that fast |
Re: Solar Energy, A Complement To FTA by mctfopt: 10:38am On Apr 22, 2019 |
earthrealm: Yeah, poor charging algorithm from the inverter may also hasten the demise of the batteries. |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 10:57am On Apr 22, 2019 |
mctfopt: sure if wrong batt type was selected, or wrong user defined voltage setpoints was inputted, hence my search for the manual |
