ojeysky: millions ke!!!! I never belleful like that ooo. please what can be done to reduce the cost.. like 600watts for 8 hours 1 Like |

limpopo: I still see millions ![]() How about you give an idea of the appliances you want to run on the setup? Maybe gurus here can give you energy-efficient options or advice on how to best optimise the appliances for lower consumption. 600w continous for 8hours is still huge. |

Re: Solar Energy, A Complement To FTA by IYGEAL(m): 12:24pm On Aug 13, 2020 |
ojeysky: Thanks. In simpler terms, you mean I should continue with the current arrangement (4p) instead of 2s2p since I use 12V? |

IYGEAL: You have better chances with 2s 2p than with 4p because of your use of MPPT. 4p on your MPPT will not give enough headroom for the CC to display its prowess to handle your 12v battery demands. So for now, go 2s 2p. When you now have enough strength to go 24v system, you can consider getting two more similar rating panels to make a 3s2p. 1 Like |

eleojo23: This one that you are seeing millions now!! okay, the breakdown.. I don remove some gadgets shaa 43inch TV - 80watts sound bar --- 70watts led bulbs (5watts) -- 8pcs -- 40 watts decoder -- 30watts phone chargers-- let's say 10watts(10* 5phones)--- 50watts fans--- (4pcs *40watts)--- let's say 200watts All the above calculation Na 470watts So, 470watts for 8hours cc Valto earthrealm ojeysky kiekie1 sathob GeorgeD1 |

limpopo: Now we are getting somewhere.... ![]() From your list, I don't think all these will run simultaneously for 8hours. For instance, your phones cannot charge continuously for 8hours so that knocks off the 50w from your continous load. I assume your continous load will eventually be around 350w. Now, lets wait for the gurus to come and give you figures in hundreds of thousands, shey that is Ok? ![]() |

limpopo:there are low wattage standing/ceiling fans that consumes less than 20w. u may have to invest in them, to bring your fan energy consumption, down to less than 80w. |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 4:11pm On Aug 13, 2020 |
IYGEAL: Am saying you should reconfigure to 2s2p so you have early wake up and late shutdown |

Valto: Can you explain number 13 please. I don't understand what you mean by wide range for Voc. Normally it's just one figure. Also what's the individual utility charge current and that for the MPPT. Which of them has this 80A? Thanks. |
Re: Solar Energy, A Complement To FTA by ewizard1: 8:52pm On Aug 13, 2020 |
Leopantro:- I have a 180Ah Battery and it lasts about 15hrs depending on what i run on it which i always keep to least minimal - Max about 500w - Yes, @24v 1.5kva - I have my inverter set to a Min and Max voltage operation. - I have the Opus battery tester. - No, its 7s100p - I used soldering - Physical Check + Capacity Check |

essegis:it means the pv voltage must be from 120vdc minimum to 450vdc maximum utility charge current is 60A inbuilt mppt cc is 80A |

limpopo: Abeg, which decoder dey chop 30 watts? Na those old type of decoders Una dey use? Except it's DSTV PVR decoder which I believe won't even fully gulp more than 15w to 20w consumption, most other decoders are in the range of 3 watts, 4 watts If your 43 inch TV has energy saving option and you get it activated, you can end up with lower consumption of between 40 watts to 45 watts. |

Good day, Please who can help me with specification to build a small inverter system. Inverter and two batteries. No solar in the system for now. It will all be powered by mains electricity for now. Maybe Solar will be in the picture in future. What is important to me is that I have an inveter with like 3kva capacity, cos I plan to gradually increase the amount of batteries i have because I plan to occasionally use 1hp AC and microwave in future. I'm asking so that I dont fall prey to unscrupulous installers. I've read the thread but so many terminologies to catch up with. What is a hybrid inverter? MPP? 12v vs 24v? What brand should I go for? Lithium vs Lead? So many questions. Thanks |

Re: Solar Energy, A Complement To FTA by ceaser: 11:27am On Aug 14, 2020 |
ceaser: NB: I realized my wattmeter may have recently been overestimating recorded consumption by as much as 12 watts. So I relied on the reading on the inverter which has been tested against at least four different appliances with good reproducibility of result. So I recorded 102 watts on the 319L inverter freezer (nameplate 115 watts) this morning after it worked for 36hrs non-stop. Then it increased to 115 watts when a bucket of fresh unfrozen fish was put inside. One hour later, it had dropped to 113 watts. 1 Like |

Morning bosses... I have to admit, I have learnt and still learning Sha so many things on this thread After my post here yesterday.. When I woke up this morning, I decided to do addition and subtraction based on some suggestions here.. I later discovered that what I really need is 350watts for 7hours max. So I started going through the thread from beginning, middle and end, even though the more I read, the more I get confused (first time in history.. me wey like to learn new things).. So my Calculation goes thus; 350watts for 7hours =2450wattshour SOLAR PANEL = Daily energy requirement/average sunlight/system efficiency 2450/4/0.75 =815 watts BATTERY BANK= Total load*days of storage/system voltage* efficiency after system losses 2450×1/12×0.8 = 255Ah INVERTER= 350×25/100 = 90 watts 350+90 = 440watts I DON'T KNOW ABOUT THE CC CALCULATION YET Please, can it be safe to say all I need; 1. 900watts solar panels (3*300) 2. 255Ah 12v Battery (or should I increase it) 3. 0.5kva 12vdc inverter 4. Charger; I don't know yet ![]() 5. Accessories Thanks to the following people for their inputs yesterday Barezzi ceaser Valto eleojo23 ojeysky |
