olaolu11: 400ah 24v will give you a good run time close to the 4 hrs you seek but I'm not sure the 600 watts panel will adequately charge the batteries to full before sundown. The gurus here will give more expert opinion. |

Trippledots: So there is this lithium pack (18650s) that is designed to be used with a laptop (19v out) and printer (30v out) ports. Charges good and at a price of 12k. Pack includes battery pack, battery charger and in-to-in plugs for the type of laptop you use. Guy is reliable, so if you wanna contact him I'll give his number here. 1 Like |

eltolu: this your CC, e no no name or specs folks should try and be intuitive when asking questions here, its quite tiring&discouraging to be asking for details back n forth, hence many will jump and pass the question 3 Likes |

[quote author=ojeysky post=82274277] As penuelseun hinted, it means 6 panels connected in series. When you connect in series you get increased voltage across panels but the current is constant. I am able to do that because my inverter allows high Voc up to 450 (with spikes to 500). However when you connect in parallel you get increased current (amperage) but constant voltage. There are ofcourse disadvantages in doing many series connection most especially the "injury to one is injury to all" syndrome, but if you have the bandwidth then I'd say it's much better. That said it is called an hybrid in this context, because it has inverter (which does the conversation from DC to AC (not the other way round) ) and solar charge controller together in one box. Note that not all hybrids are high Voc and I only got this model on choice and yes if the inverter gets to its normal operating Voc (which is 230) it can power your household without batteries. I am currently using the minimum panel setup hence am not yet at 230v not that I will need it though since I have batteries. [/quote Niw i understand. Thanks for educating me. |

ceaser: You don't mean it! My panels are configured like yours 4×150w in parallel but I use a 60a pwm cc. I am also expecting a 60a powermr mppt cc. My inverter is luminous 12v 900vac ecovolt. Pls what's the make and model of your inverter. I am looking at future upgrade is why I need the 3.5kva. But I can hold on for now. |
Re: Solar Energy, A Complement To FTA by Topmost11(m): 8:14pm On Sep 16, 2019 |
ceaser: I'm getting additional two 150watts panels before December. Will someone pls tell me how many watts will charge 400ah battery conveniently in a day with 12v inverter and as an alternative, with 24v inverter. I am yet to grasp how to do the calculations. 400ah battery. Whatever panel wattage that will charge it in a day 12v or 24v inverter? That's my dilemma now |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 8:23pm On Sep 16, 2019 |
Topmost11: If you can push things up to 1500w then you should be fine. This ofcourse depends on your continuous consumption during charging as well. I have a 1500w setup and my 150ah 24v setup becomes full by noon at the latest; in most cases it's full by 11am. |

eltolu: Just like Earthrealm has mentioned, its always good to provide details... However, in the absence of more details, one of the interpretation could be that your battery bank is already full ( even past floating). So, next time check what your battery voltage is... Float voltage for a 48V battery bank is between 54-55.2V (@13.5-13.8V per battery) Cheers |

Re: Solar Energy, A Complement To FTA by Topmost11(m): 8:38pm On Sep 16, 2019 |
ojeysky: That's about 3 hours(8-11) sunlight for 150ah on 1500w. So 10 hours(8-6) sunlight for 400ah on 1500w should truly do it. What is the make and model of your inverter pls? And make(name) of panels. I learnt there are so many stickers out there. ie you may be given panel of flames but fraudulently labelled sharp. And don't I need to consider loss along wire from panels to cc; length of wire from panel to cc is 25metres.wire size is 6mm² though I guess some of that loss will be eliminated by the time I install the expected mppt cc Thanks. |
Re: Solar Energy, A Complement To FTA by Topmost11(m): 8:55pm On Sep 16, 2019 |
@ ojesky 150ah 24v Isn't 24v supposed to be two batteries? Or you have two 75ah batteries? |
Re: Solar Energy, A Complement To FTA by mcTrinity(m): 9:00pm On Sep 16, 2019 |
Topmost11: Hello Topmost11, First of all, there's a general calculation used to determine the size of PV array for a particular system, and it has to do with using the average hours of sun in the day and other many scenario. however, I'll show you how I personally do mine looo�. secondly, I'll go the 24V way..... so, for a 400Ah battery bank, you need a minimum charging current of 40A (10% of the battery bank capacity). However, some battery have exception to this: Quanta Amaron can take up to 25% of its capacity! so at 40A charging current, you need 960W PV Array (i.e. 24V x 40A) Nonetheless, there are other considerations like day loads, panel inefficiency, and cloudy moments.... if you decide to add 10A to take care of the day loads, you'll have 50A. That'll be 1.2KW PV Array (i.e. 50A x 24V). However, you should round it up to 1.5KW PV Array, to take care of inefficiency. Note that the above is strictly my personal approach.... Cheers 2 Likes |

harizonal123:My pure sine wave inverter finally arrived in just 10days using China post and working perfectly after installing. No more humming noise and fear of my gadgets developing fault due to voltage fluctuations. Batteries now last longer compared to when I was using my former modified sine wave. It's definitely a 5star inverter & I'm very happy 3 Likes

Topmost11: Panels: Sunfit purchased from Lagos Hybrid Inverter: 3024GK purchased directly from mppsolar Taiwan. You can look to previous post on this thread where myself and other mppsolar users has provided more details about the product.
You should factor in loss, mine is about 17metre distance and am using a 8AWG dual core cable, so you should be fine with 25metre length, since you are planning on 6 panels, unless you are getting my kind of cc, I suggest you do 3S2P so you have an increased voltage to argument the amperage. Cheers PS: Am just a beginner solar DIY chap so I stand corrected by the gurus in the � |

odimbannamdi: This is the 600W Pure sine wave inverter I was talking about. It works well so far, idle consumption is about 7-10w from the manufacturer's claims and I think it's true. The fan kicks in when the load exceeds about 50w although it gets warm when using with light load. No humming sound with led bulbs and fan unlike before when I used an APC 650va Ups. The output voltage has never exceeded 225V. I paid 20k for it from AliExpress. https://s.click.aliexpress.com/e/k2IU62WU The weight is close to 2kg which is good for a 600W inverter 'cos I assume that means it is made of above-average components. It comes with two extra fuses in case you blow the follow-come during your experiment.

So, here's a retrospective review of product quality. Amazing harvest from a 3kWp PV array (hit nameplate yield). More amusing is the solar panels are knocking 3 years. CC is a Victron Bluesolar MPPT 150/85. Display is via a Victron CCGX. Screenshot via Victron VRM. Even I am wowed (which doesn't happen often). Thanks NiyiOmoIyunade for compelling me to switch to Canadian Solar panels. Thanks Zeestone for the supplies. 2 Likes

Re: Solar Energy, A Complement To FTA by earthrealm(m): 8:20am On Sep 18, 2019 |
So decided to try out quanta battery. Looks really well made and high tech. Though observed slight swellings on the 3 compartments of the battery.....is this normal. Abeg quanta users should chook mouth 2ndly the boost charge voltage spec on it is 13.8v, while float is 13.5v, this is about the lowest i have seen. And would spell disaster for folks fond of mixing diff batt makes. My usual long batts hv boost of 14.6v and float of 13.7v

Saipro: Hmm....this is interesting, you got over 3.1kw on a 3kw array, can you confirm if your array is exactly 3kw? |
Re: Solar Energy, A Complement To FTA by Topmost11(m): 12:31pm On Sep 18, 2019 |
ojeysky: OK. Now I understand. When I saw 150ah 24v was why I wondered. If I had seen 300ah 24v, I'd have understood. |

ojeysky:Actually 3,060Wp (255W × 12) in 4s3p configuration. Besides, it's the instantaneous max seen that day. I remember having spoken of "cloud edge glare" here previously. Seeing such isn't what fascinates me. What's impressive is the age of the panels versus performance. At 3pm on an average day, they output between 2.2kW and 2.5kW. On brilliant afternoons, >2.6kW. Midday yields are typically around 2.7kW to 2.9kW. It's phenomenal. 1 Like |
