earthrealm:Thanks for ur input Sir. My set up is optimal, its just that I'm looking forward to increasing my back up time from 2 batteries 200ah to 4 batteries. |

Obimind1:Of recent I've been contemplating on adding more panels to my already existing 1.2kw array. Now my question goes thus: what's the maximum amount of panels that can be used on a 24v set up with 2 pieces of 200ah batteries? My inverter capacity is a 1.4 kva. |

Chuckdee:Will adding more panels position his set up at risk? |

kiekie1:I didn't mail epsolar. I noticed that the problem was with the board of the mppt which is the heart of the cc. If there is any way I can reach ep solar, honestly I wouldn't mind. After all they is no crime in trying. A member on this forum told me how his board was changed and his epsolar came back to life, but the truth there is that he bought his own ep solar cc outside the shores of Nigeria. I don't know if their warranty really works in Nigeria. |

I'm back to my pwm which has been my saving grace for some months now pending when I'll be ready to go for another mppt.

liquidcrystal73:Sorry for the loss bro... I was in this mess some months back and sincerely it wasn't funny at all. Infact in my own case i lost both batteries and my charge controller. Honestly I felt like "why must it be me"? Did I do any wrong trying to upgrade to an mppt? Yours is more pathetic cus it failed within some hours of purchase. Mine failed after eight months of usage. It made me fall back to my pwm which I dumped long ago. But honestly I respect my pwm charge controller. Its not doing bad at all. Ever since I reported to this house how my mppt failed me, I will like to testify that I've not turned on my gen set. When they is no light from the national grid, during the day my 1.2kw array conveniently powers my home without any stress. The intelligence displayed by this pwm cc amazes me most times. It never goes above 28.2 no matter the circumstance. And sincerely it has given me some respite for sometime now. Though I still have it in mind to obtain an mppt in no distant time. But seriously if this is how an mppt cc fails I must confess that its not worth venturing into. I'm speaking as someone who was once a victim. 3 Likes |

bigrovar:The batteries that went bad were Gel batteries, but presently my batteries are AGM. |

Its been over a month now, I lost my batteries and my charge controller(60ah mppt) all at the same time under 8months of usage. It was a tough time for me though, but the truth was that I had no one to run to. I managed to get a set of new batteries which will clock one month on the 19th of this month. I also had to fall back to my 30ah and 20ah pwm charge controller which I dumped sometime ago. Now this are my findings: I noticed that my pwm seem to have an effective cut off strength compared to my mppt cc. My pwm does not exceed 28.2v at peak Sun periods and even when I'm charging my batteries with national grid power(Phcn), but when I was using my mppt I noticed that at peak periods my cc voltage rises up to 30v and every 28 day of the month it shows that its equalizing at this point my battery voltage rises to 32v during peak Sun hours. To cut the long story short I lost my batteries and my precious 60ah mppt cc under eight months. My charge controller started showing (battery OVD). Now I'm starting all over again. I must say I learnt my lessons the hard way. Had I known I would have maintained my pwm which I was using conveniently for over a year b4 going mppt. If I am to go the mppt way again, I have to do a lot of research to know what capacity of mppt cc will be efficient for my 24v set up. |

bigrovar:What type of charge controller are you using? If its an mppt what's the capacity (is it a 60a, 45a or 30a.) I'm asking bcus ur set up is similar to mine which is a 24v set up. The only difference is that my two batteries are 200ah each while urs is 220ah. My PV strength is 1.2kw (8pieces of 150watts panel) while urs is 1.8kw. If I should add 2 more(150 watts panels) to give me 1.5kw does it mean that my batteries will be at risk during peak Sun hours? |

GeorgeD1:This is my decision from now upwards. I have decided to be using my system on a skeletal basis(no heavy usage) since my system is a hybrid system with occasional 6-7 hours light from the national grid on a daily basis... I am hopeful that this way my batteries will serve me longer. |
Satellite TV Technology / Re: Solar Energy, A Complement To FTA by Obimind1: 10:09pm On Sep 24, 2017 |
dsunmade:That has been my fears too after my batteries failed me under 8 months. Though my set up is a 24v system, I used to turn on my fridge by 8:00am and turn off by 4:30pm. After getting another new sets of batteries just one week ago, I decided not to run my fridge on batteries even though my PV strength is a 1,200 watts. The highest load I use on my batteries presently is my washing machine, and I do that when the sun is at its peak. |

@GeorgeD1, Congrats on ur new upgrade. You are a proof that solar works. I'm impressed at ur high level of humility and persistence. Permit me to say u are indeed my mentor so long as it concerns solar power. May ur solar harvest keep growing from glory to glory. One luv bro! |

@ efuro, thanks for ur response... Pls I will be glad to get more suggestions. I just want to make sure my cc is safe. |

I consulted one those solar gurus on this house (name withheld) he adviced that I should disconnect either the +ve or -ve wire connecting the battery to the charge controller. After a minute or more I should connect it back. That was yesterday night.At first I was scared doing it myself to avoid being electrocuted, but finally I summoned courage to do just as he requested... Surprisingly it worked... The continues charging stopped but this morning before I left my house for the days job, I noticed it started charging when the day became bright, but noticed that when I turned off my panels connecting my charge controller using my breakers it was still charging which is very abnormal. Infact it was showing that its drawing 10amps for the panels. This is very abnormal. I called on my installer but unfortunately he is out of town. Pls any suggestion on how to solve this problem will be greatly appreciated. Thanks! |
Satellite TV Technology / Re: Solar Energy, A Complement To FTA by Obimind1: 2:17pm On Mar 07, 2017 |
Pls gurus in the house, ur advice is urgently needed. I noticed that my mppt cc 60ah ep solar keeps charging even when there is no sun. I feel something is wrong somewhere but can't exactly tell what could be the problem. |

kiekie1:That being the case, what's the maximum watts someone can use on a 24v system, bcus personally I've always wanted to add more panels to my 1,200 watts array which runs on a 60ah mppt charge controller, but I've been kinda scared to avoid exceeding my cc limit. |

GeorgeD1:GeorgeD1 Thanks for taking ur time to distinguish the difference btw the AC & DC sides. I sincerely do appreciate. |

Pls how can I get lightning arrestor? I will like to protect my mppt charge controller against thunder storm. In some month time the raining season will set in. I just want to be sure of the safety of my system. |

I've always not wanted to do this, but to encourage those who are scared of starting small... Here is a pix of my little set up, though I started in 2014 with just two batteries. Solar panels was attached to my set up immediately the official pump prices of fuel went up to 145 naira. So far so gud I've been enjoying my set up with the arrival of my mppt cc 60ah. Thanks to Kie Kie who did the supply of mppt cc not minding my location in the northern part of Nigeria. Pls pardon my arrangement cus its just temporary as I look forward to moving into my own house soon. 3 Likes
