emmy9500:Calculate by your battery's norminal voltage which in your case is 24v x 200ah= 4800wh 1 Like |

hello my people. I am looking for a very cost effective way to hook up a small solar system to power only a cctv setup. Just 5 cctv cameras, a router, dvr , power plug. for about 5 to 7 hrs during the day. not totally offgrid anyway sometimes our "NEPA" is available. Can sunking power box suffice? |

Re: Solar Energy, A Complement To FTA by Penuelseun(m): 1:53pm On Apr 13, 2023 |
emmy9500:Yes, but if the batteries are lifepo4, you calculate with 25.6v for 24v system, which is 25.6v x 200ah= 5120wh |

osayuwamwen: Nice one. What can it power and for how long?? Can u recommend a setup to use for a non inverter Hisense fridge, 7 bulbs, one tv, one ceiling fan, one laptop and two phones for 12 to 24hrs |

Some of us really need basic knowledge on solar/inverter. Without this knowledge you won't go anywhere bc you will keep calling calling calling your installer or anyone who provided assistance. Use google biko. Just typing inverter online will produce results. Annoying questions everywhere as if una get answering machine here. 1 Like |

What could be the possible cause of flickering output for MSW or is that how they are generally? I could notice the light flicker really fast. |

I want to upgrade my 12v system to 24v as I wanna add a solar setup to help PHCN charging. I already have 2 X 220ah batteries. I need help, I need know the price range of an afriipower 2.5kva 24v I read somewhere here that 2 pieces of 400watts panel is preferred to 4 pieces of 200watts. (What is the cost of one 400watts panel please) Lastly, do you advice a pwm or mppt for this setup. Thanks |
Re: Solar Energy, A Complement To FTA by Elcapitan0: 8:07pm On Apr 13, 2023 |
Hello guys. Please i have an issuei need your expertiseon. My friend have a 5kva 48v felicity hybrid inverter with 8 400w panel. The problem he is encountering is that most times, the panels does not fully charge on a well sunny day as the maximum he ever got was 800w showing with not too serious usage . He is of the opinion adding more panels which I told him to hold on for now. On the spec sheet of his inverter, i saw max solar voltage to be 145V and i saw an 'off grid' hybrid 5kva felicity inverter with 500V max solar voltage. (Don't know if they are different). Please guys what can be done? The last pics was the off geid inverter i saw

Re: Solar Energy, A Complement To FTA by Dam5reey(m): 8:28pm On Apr 13, 2023 |
Elcapitan0: He should be getting at least 2.6kw during peak periods. Try to charge with Solar only, also check maximum solar charge current if it's set to maximum of 80A. Whats the PV configuration, it looks like 2s4p, if we can see the spec sheet of the panel, it will help determine if he can do 3s or 4s Instead, your friends version can only take max VOC of 145V as stated on inverter. Also Orientation maybe an issue. |

E should not add any panel. Best is for him to bring those panels down n test them one after d other.. something is wrong somewhere. It's either the panels orientation is poor or some of d panels are bad or cable problem. Elcapitan0: |

Enter Jiji n check for different inverter prices. Message dem to confirm price. There are few of principles I can't begin to explain inorder to answer this oda question. But I'll say this. if u will use 400w panel go for yingli. It's 120k or so. Mppt CC ofcourse ianian: |

Elcapitan0: Very difficult to diagnose solar generation issues without significant information about the system, notes of things can go wrong. Here are the information you should provide. * What type of battery are they connected to. e.g Tubular or AGM, if possible provide the name or picture. How are the panels connected, e.g 2 In series (4 in series would damage the inverter solar charger because it would be more than the maximum PV input of the inverter which is at 145v. * What is the make of the panel, do you have the panel specification sheet (usually the label at the back) where did he get the panels from. * What is the distance between the roof (assuming the panels are installed on the roof) and the inverter e.g if the house is an "upstairs" is the inverter installed on the ground floor? this helps to gauge distance. And if possible what type of wiring was done between inverter and solar panel. If you don't know a picture might help. My preliminary assessment based on what you provided and some assumptions of mine. I am assuming the Panels are connected 2 in series. If this is the case, the total voltage of the panel assuming VMP is 35v might not be sufficient to charge a 48v battery system when you factor in losses. A 48v battery (assuming tubular) needs at least 57.6v to properly charge. This means the solar panel of 70v would struggle to charge such a battery system when you calculate wiring and heat related losses, in fact they won't much much room for MPPT to happen and this might account for the low charge you are seeing. If my assumptions are correct and assuming the right wire size is used, then you friend would be best served switching to a 3 in series panel configuration. This would make 2 extra panels redundant. He can stick to using 6 panels in a 3S2P (3 in series, 2 parallel) configuration or buy an extra 400w panel and set them to a 3S3S 3 in series, 3 parallel configuration. 1 Like |

Valto: Your packaging too make sense, money to chest this bill at the moment be the issue. Man just involved in some projects wey require immediate attention else things for go the other way around. I still get you for mind though. |
Re: Solar Energy, A Complement To FTA by TechGeek777: 12:37pm On Apr 14, 2023 |
Elcapitan0: From the 2nd & 3rd picture you posted, it shows the panels are supplying 63v & 172w which means the connection is in 2s 4p and this is not ideal for 48v setup. If all Panels as same products, bring one down and check if the VOC is less than 45, then you can buy one more panel with same specifications and wire then in 3s 3p. But if the VOC is Above 45v and you desire to use IVEM5048 which the Nominal voltage is 360v, then you can make use of the 8 Panels without buying another panel; if money is not an issue just buy one more panel to cater for voltage drop and wire everything in series! |

Hello! This is great but is it not the same as what Uwana Energy is doing? Check www.uwanaenergy.com they provide the system size and connect you with a solar provider there idk2023: |
