Valto:hello house I have a dilemma concerning my step up, I have a BTS HYBRID INVERTER 1200VA (720W), 2*100Ah GBM DEEP CYCLE (12V,200AH), 2*100W (12V,200WATTS) with DOD of 80% and my average load is between 150-200watts. if there is good NEPA supply, the backup last average 6-8hrs but if supply is poor the back up reduce drastically to around 3hrs. I am surprised as I expected it to be charged by the solar panels when the power supply is poor or not available so as to have constant back up time. my questions goes thus: what is it that is not right in my step up? how can I measured the amps from the solar panels? does anyone have an idea about the efficiency of the GBM battery type and my inverter? any other suggestions and advice is welcome. thanks |

emyfine08:the energy in 1 unit 12v 200ah battery is 2400wh, energy you can safely take out is max 70%, but for ease of calculation lets use 50%, thus 1200wh. so assuming you have 3 of such batteries, then you have 3600wh. so they will power this your load for approximately 3600wh/3500w -- 1hr. so to power this your load for 12hr. you need 12 to 15 sets of 3 batteries. assuming 15, so u need 15 x 3 -- 45 units of 12v 200ah battery. 1 battery is about 130k, so 45units will cost about about 6m naira. this is just battery alone. i hope you now understand, why nobody is interested in this your question. its obvious you may not have a sound understanding of how inverter systems work or have not fully grasped the economic implication of this your project... on the offchance that i am wrong, and you know what you are doing and have the financial might to see this humoungous project through, do accept my sincere apologies. make this known, as there are tried and tested inhouse installers, who would be glad to do business with you. The next issue would be, how you intend to recharge this humoungous battery bank |

bbally:Hello, there are solar charge controllers with user friendly lcd/display in pwm & mppt specs .. Nevertheless, before your gbm battery packs up >> sum up your solar panel array to 600w "factoring losses~inefficiency" ceteris paribus ! Cheer's 1 Like |

idris4r83:I think someone on this thread has indicated that his pwm does charge his LFP; So long as the controller has adjustable voltage and current I don't see why not. However have got no pwm experience on Lifepo4 |

bbally:Something missing here is the charge current of your hybrid. If you look at your battery you're actually running a 12*200 = 2400wh system. If you use an 80% DOD (which is not advisable for Lead Acid but inevitable in Nigeria) it means you always need to refill 2400*0.8 = 1920wh back each time. Looking at your solar panels of 200w working at full efficiency they will take 1920/200 = 9.6h to fully charge your batteries. Now here comes the funny part, abeg no vex as I list it. This 9.6hrs is peak sunlight. We don't have that on a daily basis. Usually it's between 4-5hrs for say we dey Africa oo. So it will take your panels 2-3 days alone to charge this battery. One thing no one will tell you is solar panels are not efficient. They are not efficient at all don't worry. Its advisable to oversize your build to take care of this inefficiency. Yours is grossly undersized. Again the charge current of your MPPT is not mentioned. The full battery you have been seeing is mainly from NEPA oo, those guys are still important even in their no light matter. Try and improve your charging system though as already ascribed by kiekie1. 1 Like |

bbally:1. What's the wattage of your solar panel(s). 2. Check your solar controller , you'll see the amperage. .snap it when the sun is high, also when the sun is low. 3. Are the silar panels well exposed. 4. when did you get the batteries, did you get them new? 5. It could be dependent on yout type of connections, in series or parrallel(both the batteries and the solar panels ) Those details are needed to further diagnose the issue |
| Re: Solar Energy, A Complement To FTA by bbally: 10:52am On May 25, 2020 |
incogni2o:thank you my brothers in the house for your response, I really appreciate. here are some of the answers to the questions raised to the best of my understanding: 1, the batteries are new and labeled GEL (if it the same as lead acid, honestly I don't know) 2, my set up is 12volts, the 2batteries and 2 panel s are both connected in parallel. 3, I will try my best to upgrade towards 600watts as suggested as fund permit 4, the setup was done in March before the lockdown. 5, the inverter has these options: DOD 50% or 80%, NEPA charging 10A or 20A, SOLAR charging 30A or 50A so, am presently set it at 20A NEPA, 30A solar, initially at 50% but now 80% as NEPA don go awire. as my panels are undersized, so if am using my electronics during the sunlight does that means the batteries will not be charged at all? I have a free 24v panel from a friend, can I connect it my existing system to increase the watt from the solar by changing the old panels to series to give 24v/100watts. I planned to incorporate a mppt which I ordered from AliExpress but is still in transit due to lockdown. attached pictures are my present setup and intended mppt from AE.

| Re: Solar Energy, A Complement To FTA by essegis(m): 6:24pm On May 25, 2020 |
bbally:Let me see if I can do a little justice to this. GEL is an offshoot of Lead Acid technology so you can categorize them as same. Solar don't do anything apart from charging your batteries. So if you use your appliances in the day time the question is, is your draw more than what is entering into your battery from the panels? If it is then you are not charging the batteries at all. I think someone used the analogy of water tank to explain this. Yes, you can connect your friends panel but do all in series as you will be having 3 dissimilar panels. Even if you don't use it I will still advise you change your present panel set up to series connection. If you agree to use your friend's panel make sure you cross check the Vmax of your CC to the summation Voc of the 3 panels and they don't exceed it. Also, if you decide to use your friend's panel you cannot use this AliExpress PWM anymore as it's strictly 12v. I will advise you save a little & pick up a small MPPT, it will give you better flexibility. I hope this helps. The house can still help join mouth. 1 Like |

Good day people Please I need answers because I think really don't know much about this I need a solar setup for just my laptop and phones for at least 12 hours daily, especially for my laptop What do you suggest I get? I've seen ones with unbuilt battery and a solar panel, how good is it? And what capacity can I get? Or should I opt for the one that I'll buy batteries, solar, inverter separate? Please I need answers my people |
