jarkbauer: Hello, transformerless or chopper transformers have lower idle consumption , light weighted and can be powered with smaller sized generators .. We also have hybrid specs with quality designs and solar integrated features in Prag brand but its not really in stock for now. It is transformer based and also has 20/40a charge current and 100a solar charge capacity . see snapshot below; Cheer's 1 Like

I know this isn't the job/vacancy section, moreso though I've been following this thread for over 2years now, this is my first comment. I'm in urgent need of a driving Job as a live in driver. I've been driving for over five years, mostly long distance Covering Uyo, Port Harcourt, Kaduna, Cross River, Abuja, Lagos etc. My vehicle went bad and have gulped a whole lot of money in the space of 4Months. I have ringed the bus (Fiat Ducato aka Boxer) thrice and the all failed at the spot. Finally the mechanic is saying I should buy a new engine after I have spent almost double the cost of an engine. Having a family of a wife, 2Children male and female 5and 2years respectively I need a job to be able to handle my responsibilities as a husband and father, think school fees, feeding, clothing, shelter etc. Getting a job is much more better than begging for money, else I would've begged for money to buy the engine. I am ready to move to any location (I'm moving alone) The pay is important, but the work environment is of greater importance, I need a Christian family to work with. I'm not a saint, but I know the value of a good name, and I protect my name with all of me. please help a brother out. Reach me via 0.8.0.5.7.5.0.5.4.0.4(Whatsapp line) or 0.8.1.6.5.5.8.0.6.6.7 |
Re: Solar Energy, A Complement To FTA by Saipro(m): 12:24pm On Mar 06, 2018 |
mukhcech: Get a 100W panel instead. Safer choice (to ensure you don's exceed max charging current). Xantrex and MorningStar make world-class PWM CC and I recommend them for bigger projects. For your project, a regular PWM CC would work. Given their propensity for overshooting the mark, set the bulk/absorb voltage to 14.2V (usual deviation is typically about 0.2V above the set limits and transient in duration). 1 Like |

Quanta Charging rate 25 % I came across quanta manual which claims max charging rate for 200 Ah quanta AGM is 25 %. If I am reading right it means the 200 AH Qantas can be charged at 50 amps without any issues Are my observations correct or I am reading it wrong. Normally I have set the charges at 10 % or max 13 % anybody has experience using such high currents 9 Life, overheating) if the values are right then 8 Quanta can be coupled with Ipower/gennex to take advantage of their 140 amps max charge ratings even if the nepa is svailable 4 hours a day

pranil: pranil, actually some high quality agm batteries can be charged at 50c or 50% capacity without any issues at all. that is one big advantage of agm over gel or flooded and it's why savvy peeps like us gravitate towards them. 2 Likes |
Re: Solar Energy, A Complement To FTA by bigrovar(m): 8:18pm On Mar 06, 2018 |
pranil: This is totally normal for AGM most can do between 30 to 40% of C20 when charging. This is the biggest advantage of AGM batteries and why it surpasses Gel. AGM is the closest to fast charging you can get from a lead acid battery. However absorption will still slow you down although you can fast charge your way out of bulk charge within a short window. |

Hi everyone, We are planning a 5KW solar panel build. 20 x 245W Yingli solar or Trina solar (255W - more expensive) either to be paid for tomorrow. AT the same time, we are now looking into batteries that we can use alongside the project and would like your opinions on the followiing two AGM batteries. First is The Victron energy 165AH (x3) The other is Rolls Surette s5000 Both pictures are attached. We would like to know please what inverters, charge controllers would be useful for these type of batteries please. (I have been advised quanta batteries also but I do have access to be able to buy other brands at a cheaper price, so I am just seeking advice on these please)

Good day Oga GeorgeD. While we are at it please would you happen to know what the recommended/ideal absorb voltage for Quanta batteries is. I have read 13.8volts as the 'freshening charge' on the spec sheet and also the Amaron Quanta website but I struggle to believe this to be true. In real life I use 14.1v or 14 2v as the absorb setpoint for Quanta batteries at client locations but I always lose some sleep thinking whether I may be overcharging their batteries. GeorgeD1: |

Re: Solar Energy, A Complement To FTA by nonoski: 1:36am On Mar 07, 2018 |
Good day house, Please I need advice. I have been using Inverters for close to 9 years and I have decided to add solar panels to my connection so I can minimize the cost of running generators to charge my batteries when Electricity is out. Although where I stay in Port Harcourt has a relative 14-18hrs light a day. Thou sometimes they get crazy and take the light for a whole week (Naija). I have 12Nr 300watts solar panels which I have mounted on an independent mount so as to use it also as a car stand. My Inverter is an Exulted 3.5Kva 48v system. (4nr 200Amps Batteries) Issues: Duh I have knowledge about Solar systems and prefer to DIY however I got an installer to help me look throu however we tend not to agree on the following 1. He says it’s better to connect 3panels in series 3 x 38.8v = 116.4v (using the Voc) and total amp of the 4 strings 4x10.21 = 40.84A (using Isc) since I will be using an MPPT While I prefer 2panels in series 2 x 38.8v = 77.6v (using the Voc) and total amp of the 6 strings 6 x 10.21 = 61.26A since it’s a 48v system. 2. I prefer using a combiner box to connect all the strings before sending in to the Charge Controller My installer prefers we just connect them using MC4 connectors and wires say combiner box is a waste of money. 3. The distance to the from the panel array to the charge controller is 45meters (148 feet), I prefer using 10mm flex, my installer prefers a 6mm flex. I also wish to change my inverter to because my current inverter has a charging current of 11.4A and I will prefer an inverter with a higher charging Amp eg Mustpower or Felicity (any positive reviews on this product). I intend to buy a Fangpusun 80A CC MPPT (is this a good product) coz I need a good CC with Digital meters I can use to study my output and possibly connect to the internet. Thank you.

BlackBaron: Blackbaron, Hello, its not like if nobody wants to help.. Most issues has been tackled repeatedly if only you devoted time to go through the pages ... Most will assume you have an idea or a pro installer you are working with with as batteries you listed aint really popular in the Nigerian market and also trying to procure low watt panels. As for me, your set up looks industrial with battery specs stated . The higher the watts of a panel , the better for you. I will go for Canadian solar 340m - 330wp , or higher wattage equivalent in either Yingli, Yachi, foresolar etc . we have high end inverters and charge controllers you can use ranging from magnum, Victron , shneider , Pt100 , connext , variotrack etc depending on the company or installer coupling your system ..

nonoski: Hello, This is unlike a small project for a client who gets 14 to 18hrs of light daily ! We have various configurations for different brands of mppts . my Itracer and outback cc prefers 3×3 for 48v systems while fangpuson might prefer lower config VOC VMP ... Simply go through your mppt manual . combiner boxes is very good for faster trouble shooting , if you can't afford the mnpv midnite specs , you can just improvise with an enclosure box and DC breakers as seen in picture below.. If disctance isn't much , use 6mm cables from PV to combiner and 16mm to mppt since you stated 80a mppt already , I believe in higher gauge cables for a long term project .

kiekie1:Ok , sorry bro. I have read up but I'd lie to say I have enough technical information to tackle such a project like this. While I know the basic components needed, I don't know enough about the correct inverters, charge controllers and whatnot to use for such a large scale model. Also with the items solar panels - batteries, etc Just that at the moment, it is going to be between a residential /diagnostics business hence we are a bit baffed on the level of sophistication this might need. I have also seen some advice for/against 'Victron' (if not conclusive) amongst other things. P.S Chuckdee, I dropped an email to you. |

nonoski: 1. The CC has better efficiency on lower voltages( 2 in series ) closely matching the battery nominal and will run cooler as a result. While higher voltages ( 3 in series) will mean lower cable losses and fewer cables in the junction box. The CC will wake up earlier and sleep later. Normally if you are running CC close to max input use 2 in series ( otherwise you will lose significant power in the afternoon). if your panels are undersized then 3 in series as a general thumb rule 2. Definitely combiner box with surge protection - buy the readymade( highly recommend midnight solar) or make yourself but definitely no twisting things together. It is much easier to troubleshoot the panels when they are misbehaving 3. see the attached file and calculate the ratings. Basically the rated current x0.8 ( correction for ambient temp) so 4 mm2 will carry 25 amps , 6 mm2 -33 and 10 mm2 -40 Based on your configuration use the correct size 4 or 6 mm2 from PV to Junction box and then from Junction box to CC suitably sized cable Best luck 5 Likes
