ojeysky:could a temporary cheap option be; moving your panels to the north or south side of your roof? that way the sun moves horizontally across it from East to West. That may help before your set up the standalone mount. |

udy821:that is your opinion. If you need quality you need to spend money. Not looking for quality for the price of cheap |

Re: Solar Energy, A Complement To FTA by kadorzy(m): 2:36pm On Jul 08, 2019 |
ojeysky: I'd strongly suggest you go for a standalone. I did same for my array due to similar challenges with roof tilt angle and orientation. |

JUO:fair answer. Personally i am using quanta which i bought frm d2h at a price a little bit above 100k . some guys here cant afford quanta but u can help them by pointing to trusted online sites . This is a do-it-yourself (DIY) forum ,some marketers spamming this forum dont even care,all what they know is to post outrageous price list then insult the real DIYer that this forum was created for 15 Likes |

Good evening house. I have been following this thread for more than a year now but this is my first time commenting. Please I want to ask if I can connect 6 units of 200A battery to a 1.5Kva inverter in order to increase the back up time. If yes how do I connect it. |
Re: Solar Energy, A Complement To FTA by mctfopt: 10:01pm On Jul 08, 2019 |
Xpac123kid: I believe by 200A battery you meant 200AH battery. To answer the question, yes you can connect it. But the question is can the 1.5kva sufficiently charge the six batteries? Also, what is the dc voltage of the inverter? Is it 12v or 24VDC? This will determine how you go about connecting the batteries. 3 Likes |

Re: Solar Energy, A Complement To FTA by Xpac123kid: 12:23am On Jul 09, 2019 |
Thanks for the reply. Yes It is a 200AH battery. Also the inverter is 24VDC. N.B: my current setting is made up of 600w solar panels charging the 2 units of 12V, 200AH batteries which are connected in series. mctfopt: |
Re: Solar Energy, A Complement To FTA by Oshomo12(m): 6:38am On Jul 09, 2019 |
Xpac123kid: Hello, I would prefer 500 watts for a 12v 200ah battery, which implies that even with ur present setup, u cannot charge those batteries effectively(u should have about 1000watts). Pls, forget Phcn/grid, it doesn't exist here in Nigeria. So don't add four more batteries to make it 6 in total, those batteries will die prematurely. 2 Likes |

dragnet: Lol, u will pay o! 12*200=2400 @50% dod = 1200 500w*0.8(ie 80% wiring, panel effncy, all thing being equal et al) = 400w At worst conditions 3hrs 400*3= 1200 Kindly critic. |
Re: Solar Energy, A Complement To FTA by Xpac123kid: 10:41am On Jul 09, 2019 |
Thanks for the advice. The reason I intend to add more batteries is to increase the backup time. Oshomo12: |
Re: Solar Energy, A Complement To FTA by Oshomo12(m): 10:53am On Jul 09, 2019 |
Xpac123kid: I understand u, but u didn't considered replacement of the depleted energy, the two go together. More backup time, more energy to source in order to replace it. |
Re: Solar Energy, A Complement To FTA by dragnet: 11:34am On Jul 09, 2019 |
Oshomo12: how much I wan pay wey go satisfy you, na knowledge we dey share. thanks for considering My query is, the load on the system and their runtime, either day or night is unknown, so we aren't even sure of the DoD to be able to make an informed decision. at 400w, wouldn't 30+Amps be too much for the battery? |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 11:47am On Jul 09, 2019 |
Dkev: Yeah I thought of that as well, but the process of bringing down the panels a couple of times does not encourage me to do that, the several holes and dents I will be giving to my roof is also a discouraging point. I am just going to plan for standalone and get it done once and for all. On that note, I will appreciate suggestion on standalone spec/design. I plan to use 3inch galvanized pipes and 1.5inch angle bars. I will be making space for 12 panels with 3 on each row (future expansion consideration) Regards |
Re: Solar Energy, A Complement To FTA by Oshomo12(m): 11:54am On Jul 09, 2019 |
dragnet: If its agm battery, 30a is ok. My assumption is for night loads only, no day daytime load considered here with an isolation of 3hrs. If daytime is involved, another different ball game entirely. |

hotdealz: You can get by if you stick to that schedule. But i think part of the fun especially with lithium things is divesting yourself of the much stress of having to frequently baby sit that battery chemistry, for it tolerates more discharge abuse than the average lead acid chemistry. I think you having to constantly look out for when it reaches 12volts may not be fun enough. What even of you have to leave home when it's charging and you are not chanced to measure it? I think a little curiosity about lithium BMSes and try DIYing some will be of great help. |
Re: Solar Energy, A Complement To FTA by ceaser: 9:56pm On Jul 09, 2019 |
Dear profs. Okay, so there is a surface well pump of 1hp that is to be weaned off of generator power and migrated to being powered by inverter and solar. Thinking the unit will be on a stand alone set up. This stand alone set up will constantly power about 2 fans and a small 22" TV (in a nearby shop the roof of which will bear the solar panels and house the inverter) and occasionally handle the pump for 2 hours at a time. Pumping will likely be every other day or at worst every three days. What would be your advice as to the best set-up (battery cap, inverter size, panel sizes and config? Also would you say PWM or MPPT? Now with the thought of going DC, some online seller gave a link to solar surface pumps. About 518usd, DC36volts, 450watts- https://www.aliexpress.com/item/32441288260.html?spm=a2g0s.imconversation.0.0.3d073e5ficYCD6&storeId=1021488 About 370usd, DC48volts, 800watts- https://www.aliexpress.com/item/32981225145.html?spm=a2g0s.imconversation.0.0.3d073e5fYTfFYJ&storeId=1021488 Overall costs of those including solar add ons appear non cost effective compared to AC pump-inverter arrangement. Which of these two approaches (i.e AC pump vs DC pump arrangement) would you say is wiser for the solution? Thank you. 1 Like |

ceaser: Questions Two fans and tv power constantly, for how long, eg 24/7? What are the fans wattage? Pumping 2hr, re u wiling to pump during the day only or u want to pump at night? Inverter A good 24v 2kva inverter will handle the work. |
Re: Solar Energy, A Complement To FTA by olaolu11(m): 5:09am On Jul 10, 2019 |
Will you pls explain how you did the connection? |
Re: Solar Energy, A Complement To FTA by ceaser: 7:23am On Jul 10, 2019 |
Oshomo12:Thanks. 1. Fans are just the low wattage (<35 watts at full op variants) x 2 makes 70 watts, with the TV and about three 5 watts LED bulbs makes lkke 115 watts (that's assuming the 22" TV take 30 watts at full blast). All these to be worked only during shop hours: 8am till around 8pm everyday except Sundays. Definitely sundown hours will span from 5:30pm, so that's like 3 hours of run off of batteries. 2. Pumping will only be during daytime and since there is a storage tank, no emergent water requirements that may require pumping during the night is anticipated. Do you imply a good 24v 2kva inverter will handle the work, especially with the load of the 1hp pump just fine? Let me quickly add that since some degree of automation (float switches and other gamut) is being planned for the entire water pump-storage system, the 1hp pump may kick in during any of the daytime moments other appliances are on the inverter. So would a 24v/2kw inverter adequately muscle the surge expected? What ampacity and config of battery bank would you recommend? How 'bout panels cap and config? Thanks.
