Draei: 1. By "Valve Regulated Lead-Acid", you mean Tubular wet batteries, Quality being same, Tubular batteires are better than Dry cell batteries. 2. you need inverter to convert the DC current to AC current. AC Currrent is what PHCN/NEPA supplies to homes. 3. you wouldn't be needing a ChargeController, if using a Hybrid inverter. Except of course you need higher capacity ChargeController, which would mean you are getting less of what you paid for te inverter. |

swagifted: You trying to compare 2 different things / terms. 1. There's Hybrid vs non-hybrid inverter 2. There's Transformer vs TransformerLESS inverter A "transformer hybrid inverter" is one that CONTAINS a TRANSFORMER, and has a Built-In chargeController. An inverter with TRANSFORMER is HEAVIER, more rugged, and could withstand more abuse such as Sparks, Spikes, surges, etc, than TransformerLESS inverter which are more portable, NOT Heavy, but LESS rugged. TransformerLESS inverter, is popularly called Sachet inverter. TransformerLESS inverter, uses MOSFET, and other semiConductors inStead of a transformer. They are more energy friendly - i.e they don't unnecessarily waste current via magnetic fields since they have no Transformer Coil windings. But they are less Rugged and Less Durable. TransformerLESS inverters, are much CHEAPER than Inverters with TransFormers of similar spec. 1 Like |

jonescosmos: love it when I see like minds in here. Additonally or Alternatively, @FEGEITOK could block all external sites, and only leave a whiteList of a couple essential to work purpose. You shouldn't have access to nairaLand if it's not useful for your jobDescription. Also you should have a way to view any user's PC screen. That alone would put them on their toes. Time Limit all PCs so it locks them out outSide Office Open hours. Disable USB ports if need be. Put consideration of skill level of the uers, so they don't easily find work-arounds. Just have a central PC (server) where all other PCs access internet from. That way, you cold allow access based on staff position e.g MD, casshier, etc |

bassdow: These tweaks you have mentions are one click away from me to be implemented. Some have also become deprecated especially the bolded statements above. An SNMP Server takes care of user activities in your workplace by logging all activities (Keyboard Strokes, Mouse clicks, Files Fingerprinting, etc on their PCs rather than spying on their Screens. Putting time limits on Users PCs at workplace was retired by Covid Outbreak when people were mandated to work remotely, which is still happening till date. Disabling USB ports is now a full option in BIOS and UEFI interfaces, you can do that if the need be but it has been deprecated also by the use of cloud services people mostly no longer have needs to carry usb storage devices. You no longer need a shared internet from a Central PC, This has become deprecated. An Internet Gateway/Firewall can do this for you by ACL I just read a couple of comments where people are asking for where to switch to or concentrate on because it makes you more money. Well I would say that despite the new or modern day nomenclatures that has evolved in computations eg, AI, Coding, CyberSecurity, etc, You must know the basics in any field you are to venture into. I am where I am today because I have had a practical hands on experience with equipments like: Alcatel, Ericsson, Huawei, TP-Link, DLink, Juniper, NEC, Nokia, Ciena, ZTE, Zycel, Orinoco, Magnums, WAVELAN, Synoptics, Kalpana, Mitsubishi, Meraki, Belkin, Fortinet, Sophos, Cyberoam, SonicWall, Calix, Aruba, Aris, Avaya, Cisco, Motorola, Ubiquiti, CommScope, Control4, EnGenius and the list goes on. So imaging me and someone without these experiences in a classroom to study CyberSecurity because he has been told that it makes you more money. Or someone who had just graduated from the University and has been told to focus on CyberSecurity because that's where the money is now. I leave you to be the judge. 4 Likes 2 Shares |

Well, for people who have been in the "corporate" world for a while and to a certain level, such inside happenings are not unusual or new. And for those who have combined it with a bit of entrepreneurship even better. Such a roller-coaster experience comes with the territory. So, again. Fire down. Na once man de die.

bassdow: When you say the TransformerLESS inverter doesn't use a transformer, then what boosts the voltage from say 12v, to whatever level that's suitable for appliances? ![]() |
Re: Solar Energy, A Complement To FTA by mank1234(m): 9:12pm On Sep 30, 2023 |
Queed: DC to DC converter then inverting as against inverting and then stepping up the AC. TransformerLESS inverter uses the former. The later is now done efficiently using toroidal transformer to step up the resulting AC. People still erroneously refer to this as transformerless because the transformer is different from the usual one they are used to. |

ManAdii:I just got inverter 3000w, charge controller and sunfit battery 100ah from jumia yesterday. Please I need your advice on the sunfit battery (is the battery last or I return it back) and how to connect the power supply to charge the inverter sunfit battery, can I charge it from my main socket or I get installer to connect it through electricity grid in my house? Anybody that knows how to do this can also explain for me please |
Re: Solar Energy, A Complement To FTA by Obnoxious2001(m): 7:09am On Oct 01, 2023 |
Please I need suggestions and opinion. I have this 24v 5.12kw blue carbon lithium battery, that has been drained. The problem now is it has refused to come up. I have tried using nepa to charge via the inverter , it not waking up, the solar panels too is not working as well... How do I solve this problem? Am thing of using an external 24v automatic low voltage disconnect switch to prevent further occurrence in the future, but I have no idea if such system is available. Beside the inverter is a transformer based hybrid inverter with 100mppt controller. I can't send image Now because of nairaland palava. Senior men please come to my aid |

Re: Solar Energy, A Complement To FTA by dacool1(m): 11:57am On Oct 01, 2023 |
mank1234: I disagree with your submission. Both transformer and transformerless inverters use transformers, just different kinds. The transformer based inverters uses low frequency transformers while the transformerless uses high frequency transformers. You can't have an inverter without a transformer. |

jonescosmos: "I just read a couple of comments where people are asking for where to switch to or concentrate on because it makes you more money." People ask me same almost regularly. They forget no matter what, the basics, background, and interest, are much more important than that money. That money would never come if you not good at what you do. You need be good enough to get more jobs, so as to be opportuned to solve more problems, which fetches that money you seek. if You're good enough, you might never have the time to spend THAT money. As for those things you say are depreciated, I made suggestions that could be implemented by just anyOne without spending money on extra unnecessary hardware, or skills. You made mention of Covid-19 and how people are manDated to work reMotely, abeg when I make comments, I try to stay TRUE to realities, especially in our enviroment (Nigeria). 1. How many companies / businesses allow people work reMotely here in Nigeria ? 2. inFact, how many businesses are built to benefit from reMote working ? 3. How much of Jumia , Konga, etc workForce work from home ? 4. How much of MTN, Airtel, 9Mobile, Glo etc callCenter / contactCenter workForce, work from home ? 5. what about small businesses, which can't afford the cost of IT department, not even outSourced ones ? The things I wrote, with a Modem Router (not even a dedicated router) sold by Nigerian ISPs, one could achieve some of them. I only responded along the lines of SAVING DATA SUBSCRIPTIONS so you don't buy 20GB data, which should last 1-month, but it FINISHES within 2-weekks, probably bbecause your staff uses over 70% of them to download Vidoes. OR Your staff spending more of the office hours, on online activites, not beneficial to your business. Just so we ain't mistaken, I'm not into netWorking abeg |

Re: Solar Energy, A Complement To FTA by jonescosmos(m): 12:10pm On Oct 01, 2023 |
Obnoxious2001: Because your Lithium battery pack needs to sense battery voltage before starting to charge, It can't help you when it sees 0V from the battery cells (0v Because your BMS has shut you off due to over DOD). So, to wake up your Battery Pack, You need to Jump start the battery just like you do to your car. But bear in mind that you have a 24v battery pack. Get a 24V external Battery Charger or An Adjustable DC Power Supply or even 2pcs of 12v Batteries that are charged up, Set the readings to about 27V 10A, Hook up the terminals Negative to Negative and Positive to Positive Terminals of the Charger and Battery respectively. If your BMS is inbuilt you might need to open the Battery Box because the terminals you have access to outside the box are P- and B+, and you need to hook up your external DC power supply to B- and B+. Once you do this and certisfying other Input conditions from your Inverter, Mains and Solar Panel sources, etc, your Battery should resume charging, then unhook the external power sources you applied earlier. If this did not help, then there might have been a fault in your BMS. I hope this helps. Cheers 6 Likes 2 Shares |

Dam5reey:unfortunately, I most times, know what I am saying. as a Kid, I destroyed and REPaired lots of things. in fact I was likely to be found in electrician's workShop, on my way home from school.of course that was because those things INTERESTs me. Don't want to say Nigeria happened to most of Us. Anyway along the line, I developed interest in Computers, and moved around from Computer enginerring TO web design TO Programming To Server admin. you can't compare when you are engaged in things you're PASSIONATE about, and when you not. But when you said what You said above, I choose to be 100% sure of what I am say so I quickly asked Aunty Google.com and here's the response - https://www.google.com/search?q=why+do+some+inverters+not+have+transformers AND https://www.google.com/search?q=inverters+without+transformers As I am now, I easily could StepUp or StepDown voltages and current any how I want without touching a transformer.
