dgr8truth:Kudos, But be wary of wood as it is quite combustible else keep a fire extinguisher at sight.. Electrical Rails would be a better option for better venting. Just my opinion though |

[ short circuquote author=Barezzi post=70188547]Guys, Is there any danger connecting the AC output of an Inverter to its AC input?[/quote] I've seen few responses to this question and I think people are mixing it up. The question is about "connecting the AC output of an Inverter to its input". for this particular scenario, I've done it to Felicity Inverter and I noticed the inverter was making a 'thud' sound (every 3sec) with the charge light trying to come on. it was as if the inverter was trying to charge the battery with its own source but some intelligent circuitry was also struggling to prevent that. The other scenario is when you connect the output of an Inverter to its input SOURCE (PHCN or Gen). now, this is not just a short circuit; it's actually worse than a short circuit. it's like connecting together any 2 phases of a 3 phase system. #MY PERSONAL OPINION.

Hello House, I have this safe power 3.5kva 48v interter with sla batteries I don't know if it a common thing, I noticed when the battery is fully charged, Even after 5 hours+, the battery is still very warm and can hear it hissing, To my view, during float the battery temperature shouldn't be too warm else it interprets its still charging with high current. I don't know if its what I should worry about or its normal for the battery to be too warm and hissing. |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 2:20am On Aug 18, 2018 |
A battery that goes hot/very warm under normal charge is either heavily sulfated or being overcharged or both. The battery hissing is a clear sign the battery electrolyte is boiling. The battery will not long survive this ill treatment especially if a sealed unit. You need to confirm what voltage the inverter is charging at during absorb and float. If the inverter voltage output is within spec then the battery is probably the culprit and is likely as good as dead already. You want to be very careful to avoid a battery explosion or fire.

Re: Solar Energy, A Complement To FTA by Feshizzy(m): 5:37am On Aug 18, 2018 |
NiyiOmoIyunade:Thank you for your reply, I checked the Volt readings when the battery were full and it was 54v, My major concern is that, is the battery meant to be still warm when it's fully charged? Charging source is from the grid. |
Re: Solar Energy, A Complement To FTA by bigrovar(m): 7:27am On Aug 18, 2018 |
Feshizzy:you might be dealing with a short cell. From the nominal voltage it seems you have at least 4 batteries in the bank. Do all the batteries have the same warm temp and produce hissing sound? Try and feel your hand be the side of the battery to see if the warmess is evenly distributed or if some parts are much warmer. Age of the battery would also be a good addition. |
Re: Solar Energy, A Complement To FTA by Reprobate: 11:35am On Aug 18, 2018 |
Feshizzy: either a wrong battery type selector switch has being selected, sending high or wrong voltage to th battery, or you have a short in one or some of the batteries. |

Re: Solar Energy, A Complement To FTA by kadorzy(m): 5:08pm On Aug 19, 2018 |
Hello great minds, hope you'll having a great weekend. Kindly oblige me a privilege to ask a quick one. What is the implication of an oversized inverter on a battery bank? For example; having a 10kva 96v for a maximum cumulative load not more than 1.5kw at any point in time. Thanks y'all. |
Re: Solar Energy, A Complement To FTA by Saipro(m): 8:35pm On Aug 19, 2018 |
kadorzy:More often than not, just an increased self-consumption by the system. 4 Likes |
Re: Solar Energy, A Complement To FTA by Barezzi(m): 5:38am On Aug 20, 2018 |
If the instantaneous loads will never exceed 1.5kw at ANY point in time, why use a 10kva 96v inverter? Other than the deep crater in your wallet, the battery bank will hardly be cycled. With the inverter operating at max 2% loading, the batteries will live forever. kadorzy: 1 Like |

Hello Wonderful People, Happy Holidays, Who has success stories as regarding topping up agm batteries with distilled water from time to time? I do understand agm are said to be maintenance free but research says that's not entirely true and mentioned they could be topped up. So I do want to understand, if it's been practiced and not just theoritical view. Oh! I added distilled water to a gatson 12v200a battery of about 9 month old due to the fact that it wasn't retaining charge and found out the cells where dry. After adding water the battery started getting hot and losing volts, so I had to quickly drain out the battery. Any insight on why it became hot after adding water because before I added water the battery was cold. Regards. 1 Like |
Re: Solar Energy, A Complement To FTA by Saipro(m): 7:25pm On Aug 21, 2018 |
Feshizzy:In theory, never try that. In practice, almost every solar enthusiast I know who's used AGM (and had dead batteries) would have either wondered about it or tried it. I've done both. Hit or miss, more misses than hits (let's say 15% success with limited extension of battery life and a very real risk of battery explosion). I witnessed poorly sealed caps pop off with such force as to displace a spanner. At best, a risky experiment. I can't stop you from trying it but I can give one really good piece of advice: have 911 on speed dial. 4 Likes 1 Share |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 8:52pm On Aug 21, 2018 |
Oga Saipro has said it all. There are plenty of DIY videos online showing how to add water to a sealed lead acid battery but the reality they never mention is a very low success rate. Part of the reason is that sealed batteries have an internal pressure range they were designed to work at - towards the end of the charging process the batteries will vent some gas outside the case - this is also why overcharging kills a battery very fast as the battery dries out from venting gas (incl. a mix of Hydrogen and Oxygen = Water). The sealed batteries are designed to vent out i.e one way -and never to take in water - so adding distilled water to a sealed battery basically ruins the calibrated internal pressure environment of the battery. The battery will tend to heat up faster while charging and may no longer vent gas safely leading to increased risk of explosion. So if you add water to a battery, be prepared to drop the charge rate well below C10, monitor it closely for heat buildup and be ready for a fire and/or explosion as combustible hydrogen and oxygen are now being vented in an unsafe and uncontrolled manner. Twice now in my life I have had batteries blow up in my face, these were random occurences from a active life working with batteries nearly all the time and I did not do anything risky like adding water to a sealed battery or such - by the grace of God and luckily for me I escaped both times without losing my eyes or suffering any permanent damage save for ruined clothing. With the benefit of these two experiences, I won't do anything that would increase the risk of battery explosion and now I always wear eye protection. Feshizzy: 2 Likes 1 Share |

Re: Solar Energy, A Complement To FTA by Feshizzy(m): 9:08pm On Aug 21, 2018 |
Sir NiyiOmoIyunade Thank you so much for the insight, I have indeed leant something that would last forever, After adding water to the battery, it seems to have shorted itself out as it voltage keep dropping, well that's the end of that battery. Thank you too Sir Saipro As indeed, messing with factory seal on battery can be unforgiving, I also did learnt this in my cause of experiment, as the seal cap were popping up with great force. In all of these, I have learnt never to top water on sealed battery, But anyway to maintain a battery, as these batteries do not exceed 30% DoD for the past 9 months but became quite unusable these past 2 months but wasn't noticeable as electricity was a bit constant for a while.
