kennypedia: Yes! exactly the type in the picture earlier shared. Wish I learnt this method much earlier when I was coupling my inverter system. Wouldn't have spent over 14k buying the miserable 'made in china' chargers. Now needed is a multimeter. Haven't got cash to spare on that now. I bought one sometime ago but lost it carelessly after barley 1 week. ![]() |

kennypedia: I love the idea! pato405: Communicating in English is not a measure of intelligence sir. Our power supply suffers alot of fluctuations which subjects how fragile the Chinese mass produced items to highest abuse. mrruns: 1. I don't think so, because absence of battery means circuit is incomplete, and normal charge controller set up won't supply DC to inverter if Inverter only is connected to the charge controller without battery. 2a. The crystal shape of cells vary. 2b. Measure output current and voltage under direct sunlight with a multimeter then multiply. 3. Yes, each cell produce s 2v and they have various combinations to provided needed output. By the way output voltage varies with level of exposure to sunlight. 4. No. Expected lifetime is 25 years. 5. Yes. The greater the distance the greater the diameter of cable recommended. All your questions have been answered before in the thread. |

vansledge: Yes. There is a red, blue, and green LED lights on the silicon board. Watch the video. The moderator explained it: RED: Current comes in & is recognised, blue charging commences, Green; Battery full. SO once it's green, you can unplug it. I wonder why we didn't adopt this approach all the while on this thread. I have more than 4 functional laptop chargers in my store wasting away! ![]() |
Re: How To Create A Locally Made Inverter With Ease by vansledge(m): 3:51pm On May 26, 2017 |
pato405:the price of that smart charger is 25k now o... so for those buying now is saving all the way o. back to my question: what if am not at home and i plug it on NEPA light (it got filled b4 i com back), because i no 1 burn person house o ![]() ![]() ![]() apart from showing the green light sheybi it wont over charge the ba3? |
Re: How To Create A Locally Made Inverter With Ease by pato405(m): 4:17pm On May 26, 2017 |
vansledge: Seriously bros, make I tell you true confession, I no be electrical engineer. The little I know about electrical stuff are things I've read on my own and my little knowledge of O'level Physics. Back to your question, I don't think overcharging your battery (while not a healthy practice for the battery life-span) can burn down your house. On the manual of the charger that I was using, the manufacturer clearly stated that once the battery is full, the user should unplug/switch off the charger as the device was not designed to switch itself off automatically. it was also written that while doing such will not cause any immediate harm, repeated (prolonged) neglected charging - e.g leaving it charging for - say 2weeks (because you are traveling) could reduce battery longevity/life span. signs of overcharging may include battery bulging on its sides. Apart from being careful to avoid overcharging, since I bought the charger (1yr & 6months now o!), PHCN has hardly EVER supplied my location power sufficient enough to charge battery fully, let alone overcharging! So I've NOT experienced aftermath of overcharging and ofocurse I can risk it because those PHCN guys have never disappointment me! Sometimes I leave it on and go to work predicting that they will not supply power for more than 30minutes. When I get back from work I often ask my neighbour who's usually at home if they supplied power, he will laugh and say they flashed it for only 15minutes! for the whole day! ![]() ![]() |

Suoer Charges are really messed up. I cracked it open and tried to diagnose the fault . The circuit design is rubbish,very little safety and protection for the components. I taught about this laptop charger idea before buying the suoer . Even without the dc to dc converter it would charge your battery,but slowly since most laptop chargers can give about 3.5 to 5A maximum. And most of this DC-DC modules are very scarce ,when they available they still have a max of 4A ,so no difference with the laptop charger . Another option is hooking up the laptop charger to the solar panel input of a solar charge controller (since they are considerably cheaper than the AC chargers). Theoretically it should work ,and there would be little chance of burning or damage to the controller ,since its taking in only dc ,what might get damaged is the laptop charger (which is cheaper to replace ). BUT i predict a lot of overheating ,since the solar controllers would want to pull as much currents as possible . I should have just built the circuit myself as i initially wanted ,I was thinking its better and safer for the battery to get what so called "advance professionals" have designed mtcheew.And time constraints to. Now 15k is burnt just like that. ![]() ![]() ![]() 1 Like |

vansledge:no but I bet phcn cannot give us 10hrs straight power supply 1 Like |
Re: How To Create A Locally Made Inverter With Ease by teamsynergy: 12:12am On May 27, 2017 |
kennypedia:mehn.. we dey get 10hrs straight lately for my area oo... buh we shoulkd be able to build a battery full cut off circuit , i just dont know if the powerpack is gonna charge 200ah battery without overheating and damaging the board. its kinda easy to fix laptop powerpack sha. its one big capacitor inside that usually gets damage, once replaced, the powerpack is go to go again... nb: i think a diode might be necessary at the output side of the dc converter to block reverse supply from battery.. if the voltage is kept at around 13.7-14.4v with 4-5a, i doubt if that is ever going to over charge any deep cycle battery from like 60ah upwards, at most its gonna jst tickle the battery ( float charge) 1 Like |
Re: How To Create A Locally Made Inverter With Ease by kennypedia(m): 5:08am On May 27, 2017 |
teamsynergy:its a ac to DC system you don't need diode again it back to ac . its a DC step down a DC converter is called inverter 1 Like |
Re: How To Create A Locally Made Inverter With Ease by kennypedia(m): 5:20am On May 27, 2017 |
pato405:the green light doesn't stop the charging process which means you have to unplug manually |
Re: How To Create A Locally Made Inverter With Ease by kennypedia(m): 5:26am On May 27, 2017 |
vansledge:it will . reduce the charging amp before travelling or going out if you have constant power supply |
Re: How To Create A Locally Made Inverter With Ease by kennypedia(m): 5:31am On May 27, 2017 |
pato405:over charging causes hydrogen gas to build up inside the battery it will cause swelling and if care not taken explosion 1 Like |

mukhcech:u can get from Ac, water dripping out of an air conditioner , carefully poet the top of the batteries, u will see 6 holes, pour the water in to dem,don't cover the with the rubber cover or plastic top cover,after some days of charging,u can now cover |
Re: How To Create A Locally Made Inverter With Ease by kennypedia(m): 6:59am On May 27, 2017 |
teamsynergy:you can get up to 20amp from the charger |
Re: How To Create A Locally Made Inverter With Ease by timifakay(m): 7:52am On May 27, 2017 |
kennypedia: How please? I just checked 2 laptop chargers and what I saw were 4.7a and 2.15a outputs. |
Re: How To Create A Locally Made Inverter With Ease by teamsynergy: 7:55am On May 27, 2017 |
kennypedia:the diode maybe necessary to prevent reverse flow, not rectification. |
Re: How To Create A Locally Made Inverter With Ease by teamsynergy: 7:57am On May 27, 2017 |
timifakay:i don't think a laptop power pack can supply more than 5a |
Re: How To Create A Locally Made Inverter With Ease by kennypedia(m): 8:39am On May 27, 2017 |
teamsynergy:a diode is used for both |
Re: How To Create A Locally Made Inverter With Ease by kennypedia(m): 8:46am On May 27, 2017 |
teamsynergy:yes 5a in 19v when you step the volt down you can increase the amp. physics stuffs there is different between volt and current |
Re: How To Create A Locally Made Inverter With Ease by kennypedia(m): 8:53am On May 27, 2017 |
teamsynergy:have you ever thought of why we use different types of wires in electrical settings. this live wire can carry high watt but can't carry high volt. high current low volt that's why it can travel long distance. while the ones we use at home 240v wires cannot handle high current |
Re: How To Create A Locally Made Inverter With Ease by kennypedia(m): 9:18am On May 27, 2017 |
teamsynergy:can a DC current flow back into a ac powered board. I really don't know please can you explain? I worked with dad in his shop from 2009 to 2014 non stop and still do once a while he never told me this. I wish I am studying EE engineering but Transport technology and infrastructure TTI took me proudly lasuite |

its now over one year i moved over to a more efficient PURE SINE WAVE INVERTER/CHARGER, all this souer charger and inverter frustrated me big time back then. i av to repair the souer inverter several times till it packed up. big ups to ceejay80s, saint2ace and the rest, who inspired me to start this solar/inverter journey. there is nothing better than uninterrupted power supply ![]()

Re: How To Create A Locally Made Inverter With Ease by teamsynergy: 10:16am On May 27, 2017 |
kennypedia:still I don't think that board can deliver up to 20a |
Re: How To Create A Locally Made Inverter With Ease by teamsynergy: 10:18am On May 27, 2017 |
kennypedia:it can flow back to d DC convert if a diode is not in place. more like a solar panel connected to battery without a diode |
Re: How To Create A Locally Made Inverter With Ease by kennypedia(m): 2:21pm On May 27, 2017 |
teamsynergy:solar power is in DC not ac take note . the solar cells are generating DC v |
Re: How To Create A Locally Made Inverter With Ease by teamsynergy: 3:42pm On May 27, 2017 |
kennypedia:the module u are connecting to ur power pack is a DC DC converter, no ac is involved.. note that |
Re: How To Create A Locally Made Inverter With Ease by kennypedia(m): 4:26pm On May 27, 2017 |
teamsynergy:yes if is drawing back current then any of the lights will be on. we can also use a multi meter to test for current if it actually drawing back current |
