efuro: You are very correct! What I am doing now is that I have bought 3 different types of bulbs (all in 3.3 w). Two are still serving (8 months), one just lasted 6 months. I use them for my security lighting, which stays on for 11 hrs each day. When I conclude on my tests, I will recommend it. |

A battery balancer e.g Victron Battery Balancer will help ensure that each battery in a series connected battery bank gets an equal amount of charge or discharge - it is especially useful in your scenario where you have a few batteries weak out of a larger bank of series connected batteries - while the bank is being charged, the weak batteries will tend to be undercharged and vice versa when the bank is being discharged. A good balancer will help shuffle power between the batteries such that an eventual state of balance is achieved - balancers are generally not very cheap and represent additional wiring complexity between the batteries. Pertinent to note, the balancer is not a magic device restoring equality to several batteries which are very far apart in capacity or performance. You will need to first isolate your weak batteries and give them a proper full charge and equalize cycle before adding them back to the main bank and then installing as many balancers as are required between the batteries. All the balancers I know are set for 12v batteries, you may suffer additional difficulty trying to use them in a 6v bank but you could batch the bad 6v batteries in sets of 2 to make them up to 12v. For desulphators, I have been using them from day one on several battery banks and batteries have gone bad regardless and even suffered the very sulphation the desulphators were designed to prevent ![]() Because your current bank is 2 years old, if you buy just a few batteries to replace the bad ones you will ultimately end up with a mismatched battery bank - the older ones are likely to fail earlier than the new set you just added and you find yourself keep replacing batteries piecemeal and never really enjoying the full capacity of your battery bank. If you are really unlucky, the older batteries will even put strain on the newers ones making them work harder and wear out faster. I won't say mixing old and new batteries cannot work but certainly it is something you want to think through thoroughly especially with your huge bank of 16 batteries lest you go down a destructive path. Your overall best bet is still to try to revive the weak batteries you have. Get a temperature compensated hydrometer and get familiar with SG readings and how they indicate battery state of charge - Given that your batteries seem to have gone bad pretty quickly after you had issues with your mains supply, I have a sneaky feeling you were really not giving your bank a full charge before now or your absorb voltage setpoint was too low.

DBlackCeazer: Its like you have not been maintaining your battery bank properly. To determine the best way to resolve your battery issue, I would like to ask you few questions 1. Are you charging with inverter only, solar only or both? 2. What is the size of your inverter and solar array if any? Your inverter and panel brand? 3. What is you Bulk, Absorb and Float voltage.? What is your absorption time? 4. How often do you equalize the batteries? 5. What is your average house load? You can reach me on mobile 0803 260 2629 to discuss further.

Re: Solar Energy, A Complement To FTA by makavele: 6:09pm On Jan 11, 2018 |
^^ he needs a 12V inverter that can output a decent 50A or more to get those batteries in good shape . . . Too much going in there; less efficiency. If it were to be a 24V setup, only needs about 25A or so But his battery amount is lacking . . . That's why i prefer 12V batteries straight up. By the time you start stacking 2V batteries to make 24V; mehn . . where is the space sef ? 1 Like |

Very valid points. But the man has purchased what he was able to and now it's left to derive maximum value from the purchase. I too do not really like 2v and I'm getting increasingly disillusioned with 6v flooded batteries too. Give me a solid 12v AGM any day and it keeps everything simple. In this specific case, the OP's bank is equivalent to 2.5 standard 12v 200ah batteries - a decent battery bank and altogether not bad at all as an entry level system. I can confirm that JUO's 12v ICellPower inverter will do 50amps charging without stress. I recommended it ahead of MustPower because of the lighter footprint and the ICellPower is also at least 10k cheaper - MustPower's have higher idle consumption which will drain the battery unnecessarily. All in all, the OP will be quite happy with his 2v batteries once he ensures a regular full charge & does not discharge his bank below 50%. makavele: 3 Likes |

c0ogumo:thanks for your time 1.both 2. Inverter is 10kva, not sure of solar wattage, 32 nos. of panel. Inverter brand is Prag, again not sure of the panel brand. 3.the batteries quickly jumps to a hundred percent charge as indicated by the inverter whenever power is restored, say in 15 minutes. 4.can't lie, the batteries have never been equalized. 5.the inverter reads 40% load at peak periods. That's roughly 4kva. |

NiyiOmoIyunade:12v batteries are easier to install, but has limitations as regards the amps per hour. I don't like the idea of looping several batteries to achieve higher Ah. |

I have used several of the Battery Life Saver (BLS) series as well as the PowerPulse desulphators. Certainly all of them have an effect but certainly again they are no substitute for proper battery charging and making sure batteries get a daily full charge and are not deeply discharged below 50% of capacity. If you know other desulphator brands that you believe perform miracles then please suggest them to the house - I am always happy to try out new stuff. teamman: |

teamman: i've been using the battery life saver (bls) for several years now and it definitely has been positive stories for me all the way. the bls coupled with other maintenance best practices has ensured my battery bank continues to perform as new even after 5yrs. 1 Like |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 8:54pm On Jan 12, 2018 |
Perhaps the BLS just shines that green led light and the heatsink gets warm and it is actually your other maintenance best practices, daily full charge and no deep discharge that has kept your battery bank going these 5 years. In the end I don't really know. All I know is I won't be buying any more desulphators for now. GeorgeD1: 3 Likes |

NiyiOmoIyunade: Thanks Niyi. I still have challenges achieving full charge everyday. In most cases, i get past bulk charging to Absorption phase around 4pm everyday except yesterday that i got to floating stage because we had grid supply BY MISTAKE!!! I try to ensure i don't go below 55% DOD as I am practically living off grid. We only get power supply whenever there is a major fault ![]() A quick question, i am planning to increase my panels so as to cover for my day use and also enough to fully charge the battery for the night. What brand of panel are you using? I am considering 300w Joysolar or may be Sunshine. Is there any other reasonably priced panels i could explore? Thanks |

I use Flames 300w Mono Panels (21 units) to make up my 6.3kw array - sourced through Zeestone99 on this forum. Flames is a chinese product but I have found it to be good bang for the buck. But please don't rush to buy more panels yet. What brand of panels are you using currently? You want to be sure to either keep the same exact panel brand and specs (VoC,VmP,Rated Current) or match them very closely. If you mix panels anyhow you may get suboptimal results especially when they are all connected to one CC. Let us evaluate your loads and battery consumption vs. solar yield. Since you are ground mounted, have you washed off the harmattan dust from your panels? What kind of yield are you getting now? Your yield should be getting better as the year progresses except you have other issues e.g shading/shadows on your panels If I assume you consume 50% of your 600ah 48v capacity between 6pm and 8am everyday that is 300ah @ 48v or roughly 14.4kwh overnight - this is a lot - do you run ACs off your batteries overnight? Have you put a timer on your freezer/fridge e.t.c. Do you have a meter to measure your overall household consumption per time e.g via the inverter monitoring interface?. We should tackle this issue holistically because even if you get enough panels now to ensure a daily full charge, 50% DoD will give you a 2 to 3 year battery life and you can easily do better with a few tweaks. olagunju2000: 3 Likes |
Re: Solar Energy, A Complement To FTA by makavele: 1:35pm On Jan 13, 2018 |
DMerciful: Yes sir, the test were done at the same time . . . I had to borrow the same charge controller from a friend, identical to me, in age and specs. And test was carried out on the same battery bank; same load Same panel configuration . . and I was monitoring . . Even if there were to be a disparity; it should be within plus or minus 10% . . But 55% to about 80% margin was too wide . . . Trust me, I repeated the tests again some other day; and i got about 55% to 70% No matter what I did, the Sunshine panels would not output past 55% of its peak power What a shame !!! 3 Likes |
