pcoolioz: An interesting situation. Use a meter to determine the true voltage of your battery. If your inverter is the one displaying wrong voltage, check the battery terminal on the inverter and be sure it is properly tightened. If that did not work, check if your inverter has a voltage calibration menu and adjust as necessary. If none of this works, your inverter may need repairs. 1 Like |

Is the inverter connected to a solar pv array and to NEPA ? If yes, for the AC lines, you will need a Type 1 surge protective device at your NEPA distribution board where the cables from your poles are terminated and a type 2 SPD very close to the inverter AC terminals. For the solar PV input cable, you will also need a Type 1 SPD upstream and a type 2 SPD close to the solar input of your inverter and the earth terminals of all the SPDs must be connected to a ground electrode with no lower than 10 ohms resistance. A lot of what I said will likely not make sense to you because lightning protection isn't really a DIY thing Expertt: 1 Like |

You need to set the high voltage disconnect on your BMS higher than the bulk/float charging voltage you set on your inverter. This hack if it can be called that is courtesy of @niyiomoiyunade. pcoolioz: |

I have never questioned that Lithium chemistries like Lithium Iron Phosphate are superior to most lead acid. The issue was the initial outlay to acquire a premium system like Pylontech - they cost enough at the time to acquire a very much larger Ah capacity of Lead acid. Lithium benefits are energy density, light weight, ability for deep discharge and a far higher probability of achieving the expected cycle life just to mention a few. These days there are many affordable DIY Lithium options and the cost is pretty close to lead acid with superior performance and longevity. ojesymsym: 6 Likes |

Besides I do not know anyone doing it currently. And am simply buying things for installation so I don't think it's wrong buying lpd and spd also so that the installer will fix everything once 4 Likes |

Expertt: Your concerns are valid. I did the same thing. Before I zeroed in on Schneider inverters and Quanta/Deka batteries. I spent over a month studying inverters and batteries including reading reviews. Same thing now that I have learnt that I should consider the lithium batteries, I have suspended purchase in the meantime while I study up, so I can relate on the knowledgeable basis with whoever I shall be buying from. If you cannot get the help, you want here, then consider 1. Reddit and 2. YouTube 3. very specific google searches, the answers you seek might be found there. One thing I have learned from this thread - without those SPDs, your installation is incomplete. My practice was to disconnect my inverter from the wiring of the house during rains and thunderstorms but installing SPDs makes more sense. 1 Like |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 9:22pm On Aug 03, 2022 |
Before SPDs people have to get their protective earthing done right because the fault currents and voltage potential from a surge or lightning hit will have nowhere to go to if there is no proper earth in place. Once you have a proper Earth system in place with sufficiently low resistance then you can step up the level of protection with SPDs. SPDs mostly limit the voltage rise seen by the protected downstream equipment - this is one reason why premium gear is more robust since they typically have a UL label which means they were tested at the lab to be able to withstand up to 2,500volts. Good SPDs are not cheap, a lot of the el cheapo asian junk that go by the name SPD have no published or proven clamp voltage rating. In the end you get what you pay for. Doing a premium midnite SPD on the mains incomer and PV lines could easily set one back 200k - may not make sense to spend 200k in SPDs to protect a 500k inverter - you kind of have to match the cost of additional protection which SPDs offer to the value of the protected equipment and any downtime. Just to balance the discussion around surge and lightning protection. FEGEITOK: 3 Likes |
Re: Solar Energy, A Complement To FTA by FEGEITOK: 9:34pm On Aug 03, 2022 |
NiyiOmoIyunade: Thank you for your input, comments like this and the debate over types of batteries is why I suspended my purchase in the meantime. For me SPDs are a most. I am going for an 8KW PV array and at least 10KW battery storage for a minimum and 30Kw storage maximum. With that much outlay I have to protect it with all that I have, that said what has slowed me down is understanding which batteries to go for and why, so as to achieve the best cost/performance ratio. Since my initial plan has been queried on this thread. Once again thanks for your expertise and willingness to share. |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 10:04pm On Aug 03, 2022 |
For SPDs the Midnite SPDs for AC and DC applications are top tier. Schneider produces some Acti 9 SPDs as well which are more budget friendly. Whatever SPD you choose, you just need to match the mcov and clamp voltage ratings to your equipment. Again you probably shouldn't use an 100k SPD to give additional protection to a 300k inverter. For the ultimate protection you would need SPDs and voltage and overcurrent protection on the mains input, SPD on the PV input and SPDs and overcurrent/shortcircuit protection on the inverter AC out. The costs of protection stack up pretty quick and you may need a risk assessment of your site to decide where best to put your protection dollars. FEGEITOK: 1 Like |

dollarnaira: there's really no need for name-calling here, i think. you have to remember that we are all here for one purpose - energy freedom (or so i think) what myself, samnaija and others are trying to tell up and coming solar enthusiasts is that you know what? before lithium came onboard, there was lead acid. you don't have to be straight-jacketed into one type of battery chemistry. you have options. for all the draw backs of lead acid, namely: 1) it occupies space - not everyone is space constrained (many aspiring renewables enthusiasts might be living in their own houses, so space is not an issue for them) 2) it is heavier and not easy to carry - again that may not be a deal breaker for many as long as they don't live a nomadic life. battery banks are not meant to be moved about once they're installed. even the usual battery rotation is done every 12 or 24 months in some instances. 3) the energy density is lesser than lithium - while this may be true, except you plan to use your battery bank to run an electric vehicle which has a high current draw, this shouldn't be a problem. if your sole aim is to run your house loads, i doubt there's any domestic appliance that would require such high current draw which your lead acid cannot cope with. 4) dod of 50 (for lead acid) as against 80 or 90 percent (for lithium) - this also is not a challenge for many as proper battery bank sizing easily takes care of this. 5) it has shorter life span compared to lithium - while this may be true, we have had lead acid banks lasting way beyond their projected end of service life with proper system sizing and good maintenance practice. my 2v single cell batteries are projected to last 15yrs by the oem. even if i'm able to get just 10yrs out of them at the end of the day, it would be a major step forward for lead. besides all the above, what we would like the newcomers to understand is that despite the much acclaimed drop in price of lithium compared to lead acid, on a price per watt basis, lead acid is still a cheaper option. so, if a person who is contemplating going solar is reading all this and all he is seeing is lithium, lithium and he goes to check the cost of buying a lithium pack, and then throws in the cost of purchasing an appropriate sized bms with all other bells and whistles, he gets discouraged and walks away thinking, "you know what, solar is too expensive". over ten years ago, when we started this thread, we were all grateful for the opportunity to learn by building our systems from scratch using simple, tried and tested methods. they were cheaper but they got the job done. we want newbies to be given such opportunities too. they don't have to be teleguided into a particular method or battery chemistry. let them try for themselves and see what works and what does not. that's the beauty of diy and that is overriding aim of this thread. if we all are objective in our submissions, there would be no need for name calling. and, if we all are able to achieve our ultimate goal of energy freedom, it would be a win-win for us all. break the myth! you know you can!! 11 Likes |

NiyiOmoIyunade: Based on some of the statements above quoted, I conducted further directed research and found this https://blog.se.com/power-management-metering-monitoring-power-quality/2013/03/19/how-to-choose-the-right-surge-protector/ Expertt, hope this helps you some more. Basically you need at least 2 SPDs and 1 MCB SPDs 1. Mains in aka grid power coming into your premises, think of it like a bridge between your entire house wiring and grid power 2. PV in aka your solar power supply, think of it like a bridge between your entire house wiring and your solar panels MCB 1. Inverter out aka the power your inverter is supplying before your equipment received it, think of it like the bridge between your equipment and your inverter However, SPDs work with earthing, which I believe is best left to an electrical contractor to install, because the excess current needs a safe return path Little wonder then that @Niyi rightly makes the point that complete protection will be expensive! That is why there was a poster that said this is not a DIY thing, but even if it isn't, if you don't gather some knowledge, you will be lost communicating what you want to your electrical installer or even determining if he is doing a good job for you. The risk assessment part might be best reserved for professionals, but like the adage goes no knowledge is worthless 1 Like

GeorgeD1: Do not explain anything to anyone. This thread is for everyone, all of a sudden if you cannot speak again. God forbid you mention lead acid battery. This is a forum for matured minds to exchange ideas ,but some people take it has a personal war. I will say it again again, lithium is the new baby in town. If you have the money no problem. Then there are alternatives apart from lithium Which don't cost an arm and a leg lead acid. I am not a salesman , but an enduser that started solar journey through this forum. Has long has my lead acid batteries are in service , if anyone ask a question about lead acid I will answer the person. So if it angers you to hear about, lead acid feel free to touch a bursbar. .... |

samnaija: Those who talked about lithium are also users(end or middle or high ), I still bought lead acid last month for setup somewhere but do not take it personal when people state the obvious superiority of lithium over lead acid..... This thread is here to state our experiences and advice but ultimate decision rest with individual so tagging everyone that prefers lithium over lead acid as marketer or seller could mislead users. That said, I actually wish actual marketers on this thread actually share their experience when people ask questions 9 Likes |
