[quote author=tonididdy post=85775937][/quote] Just a recommendation 1. Remove the Inverter from the top of the battery, after prolonged usage your inverter may be hot and your batteries will start emitting gas.. 2. Replace the battery clamps with Battery lugs, those Clamps do have bad contact and may corrode if you pass high current Which as a result of excessive heat.. 2 Likes |

Hi House, I bought a set of panels from a renowned and respected person on this forum known for warning against fake solar panels and accessories. i have transacted business for a long time with this said person and had no cause to doubt his integrity. however my last transaction with him gave me reasons to question his business dealings with me as shady as i ordered for panels (three 250 Watts) and he told me he was sending flames panels which he got direct from the company. Unfortunately, when the panels came, there was no indication that it was a flames panel and the installer confirmed same. as at 1pm, i was getting less than 2Amps current on a single panel and it was quite sunny. Since then the person has cut off all communications with me as he was also trying to get kickback from the installer (which i got to know about later and refused to work with his agreement), this is after overpricing[color=#990000][/color] even the logistics of how the items got to me. please i am just curious, is it possible to buy a flames panel without the sticker indicating that it is flames? is there anyone with sample picture of how flames panels look? thank you |

I bought and installed over 100units of Flames 300w Mono panels before I moved to strictly Tier 1s like Canadian Solar. All the Flames panels I ever saw had their sticker specifying ratings and all - however, a sticker is not a badge of authenticity - Alaba folks are able to produce any sticker and slap it on any generic panel. You are usually better off buying direct from a genuine source vs. a middleman. A google search would have unveiled at least two Flames dealerships within Lagos who are willing to sell to you and support you after sale. My advise would be to pursue peaceful avenues of resolution with the person you bought from - no need for the relationship to degenerate to the extent that he cuts off contact with you. If you already have Flames panels you had bought earlier, then let him explain/justify why this new set have a worse performance. Have you eliminated other causes e.g time of day, shading, battery State of Charge, simultaenous charging with PHCN or Gen that may drive low yield? Have you tested the panels over more than one day to see how they hold up? oliyeniun: 2 Likes |

Re: Solar Energy, A Complement To FTA by Topmost11(m): 3:06pm On Jan 14, 2020 |
tonididdy: That is what is called parallel connection(+ve to +ve; -ve to -ve). Series is two panels joined(one +ve to another -ve), then one +ve and one -ve from each panel is now taken. You can do if you want to. Sir, may i give a piece of advice. This is a DIY forum but you need to study on solar. "Nobody wants to build a house without first counting the cost". Several wrong and partialy right advice is rife here based on point of view and extent of knowledge. If you dont update yourself, you will br disappointed with this solar thing. Paucity of funds made me go the DIY way and i have not regretted i did. Find time to read up sir. 2 Likes |

tonididdy: Sir there are no fulltime members here. People only respond when they have the time. Yoir cc says your max pv input is 390 watts and you already have 300. Meaning you have space for only 90watts. But given efficiency factor in the system yield. I think you can still add one or the two panels so far as the total voltage does not exceed voltage of 50v and current of 30amps that is the maximum of your cc capacity. Suggestion is: wtrire down the presenrt yield. add one more panel, see the result, write down the total voltage and current. Remove the new panel, add the second new panel, write down the combined voltage and current. Thus you have known the individual yield of the two new panels. If you now add all together( old yield and new yield) if they are not above 50v and 30a, then you are good to go. My take, but i am subject to correction by the gurus in the house. 3 Likes |

NiyiOmoIyunade: If someone refuses to pick my calls again, i see no reason why i should hide his/her identity. There is a seller on this platform whose after sales service is minus zero. I learnt he will even insult you if you disturb him too much. I read about him on another forun on nairaland. His name is promininent on this platform as well. Only thing is you have been transacting business with him for years without problem. What now happened? 1 Like |

Valto: Let me stick to my chinko panels with low yield than buy same rebranded/misbranded chinko panels at premium price. When i dont know about a thing, i search the net for info on it. Then utilise the info gathered. Barrister Jimoh Ibrahim(global fleet oil) was reqruiting managers, he taught them the essence of information. I learnt a lot from the session. 1 Like |

Re: Solar Energy, A Complement To FTA by tonididdy(m): 7:23pm On Jan 14, 2020 |
Topmost11:thanks sir. This setup is for my granny. I don't want it to last only a year and that's it. The installer is a very busy guy. I have to do this myself. |
Re: Solar Energy, A Complement To FTA by tonididdy(m): 7:29pm On Jan 14, 2020 |
Topmost11: Hello sir. Good evening. Thanks for taking time to reply me, I do understand replies are based on time factor. My setup is just one 220AH battery, 12v system... The installer said it's a setup for mostly night usage and I have to compliment it with NEPA and Gen. I believe a full charge on the CC will be 50v (forgive my ignorance). At night we use between 13.1v to 12.2v at night by dawn according to the CC readings. Am not an electrical guy, it's hard for me to understand these terms and usage. I will take your advice and add a 150w panel. I hope it doesn't blow up my battery. |
Re: Solar Energy, A Complement To FTA by Topmost11(m): 8:57pm On Jan 14, 2020 |
tonididdy: I stand to be corrected. Max that your cc can take is 50v. The draws(power being used) from your BATTERY is what you are seeing as indicated on your cc as 13.1 to 12.2(thats why it is reducing). You will see the shape of battery when that reading is indicated. It is different from your panel load(which is indicated when you see shape/logo of panel on the cc screen. Your cc will accomodate that. On attached pix, you see 8. +and 32.+ but it may instead of 8.+ not show more than 4.+ . My panels that is 4×150 watts panel to total 600 watts in reality gives me max of 23+v and 17+a.

Re: Solar Energy, A Complement To FTA by Topmost11(m): 9:07pm On Jan 14, 2020 |
@tonididdy. I suhhest you go to the beginning of this thread ie 1 and read till 10. It will answer most if not all your questions. Best of luck PS: endeavour to remove the inverter from on top of the battery ASAPas advised. Your installer is not a nice fellow(forgive my use of the language). Did he forget these things heat up? |
Re: Solar Energy, A Complement To FTA by tonididdy(m): 9:11pm On Jan 14, 2020 |
Topmost11:One question please, do you really think (according to my CC details and setup) that I can add extra 300w panel to this setup? |
Re: Solar Energy, A Complement To FTA by tonididdy(m): 9:12pm On Jan 14, 2020 |
Topmost11:Ok thanks, I will do this first thing in the morning |
Re: Solar Energy, A Complement To FTA by Topmost11(m): 9:18pm On Jan 14, 2020 |
tonididdy: And what is the capacity of your cc, 10,20,30,40,50,60+ amps? Post the reading of your cc when at solar panel and when at battery so we can see your harvest first. |
Re: Solar Energy, A Complement To FTA by tonididdy(m): 9:30pm On Jan 14, 2020 |
Topmost11:ok this? I can have a batt3 reading on the CC of 12.9v as at 5pm...because immediately usage kicks in, the reading drops immediately to mostly 12.9v and by morning, I will have 12.1, 12.2 and the batt3 bar would have dropped to 2bars. It's never emptied overnight before.

Re: Solar Energy, A Complement To FTA by tonididdy(m): 10:30pm On Jan 14, 2020 |
Topmost11:Hi friends thanks so much for your mentions. I really appreciate. I took your advice and studied the first page to know exactly the wattage of panel I would need for my setup. This is the calculation I came up with according to page 1(i maybe wrong though, forgive my ignorance but I willing to learn and take corrections). According to page 1,to know the panel or batt3 needed, one needs to know the sum total watts of all appliances expected to be used and hours expected to be used, multiply by 1.2 (this is if we assume to get at least 85% efficency considering no setup is 100%) and then divide that by the number of hours of sunlight got a day... The total is the required wattage of panel needed. Using this guide, I calculated thus: TV 60watts X 10hrs usage (5pm to 2am) Dstv 30w X 10hrs Fan 30w X 20hrs Equals 600+300+600 Total 1500wh 1500wh X 1.2 equals 1800wh To know the panel needed We divide 1800 by 7hrs (this is the sun uptime, if the sun is best at 10am to 4pm) 1800wh/7= 257w. This means I need a 257w panels to supply energy at my given time and my setup has 300w panels. BUT in all of this, why don't I get full charge after 7hrs of sunlight? Does this mean my panels may not be giving 300w supply to the batteries?

Re: Solar Energy, A Complement To FTA by solasola(m): 10:34pm On Jan 14, 2020 |
tonididdy:from the little I deduce, your system is running very well. dod is around 50-40%, so why do you want to add more panels?.Check you cc manual for the max current. |
