Re: Solar Energy, A Complement To FTA by FEGEITOK: 7:27pm On Mar 06, 2023 |
It has rained literally 3 times since the start of February in Abuja. I had to disconnect the incoming PV wires from the charge controller this evening as the rains were about to start. I initially approached the issue of earthing from the point of view of creating separate earthing for the PV system then found out that it is better to earth the whole house and then the earthing for the PV system but connect them to each other - they call it "Lightning equipotential bonding" The idea is to reduce the potential differences caused by lightning currents by interconnecting all isolated conducting parts of the installation by means of conductors or surge protective devices. This line was adapted from Dehn's literature. Obviously, I need to kick this lightning protection up my to-do list. Please note: I know that lightning can strike anytime, not just when it rains! That said there is a very interesting thread that tells us, that it is not just the solar panel that should be earthed. Literally, everything needs to be earthed including your DSTV dish. I just totally literally disconnected mine from my TV and the rest of the electronics

Please do anyone know the service center of Must Inverters in Lagos please? I need a Must PV18-1012 VPM repaired. Also, I need a Low Voltage Disconnect module with up to 50a rating, can I get locally? |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 8:22pm On Mar 06, 2023 |
Consider what it means to interrupt 50a of DC current - the contacts must be beefy and huge. You can find 'battery sensing relays' such as XHM6** series on AliExpress. What you want to do instead is setup Battery > XHM6** > DC Relay/Contactor and then use the main contacts of that DC Relay/Contactor to interrupt the inverter AC Out. So really you are looking for the XHM6** to detect the battery voltage state and the DC Relay/Contactor to (dis)connect the AC supply to the loads. In practice you need to consider battery voltage hyteresis and recovery points and also what happens if mains becomes available (ideally want to override the battery voltage based cutoff in the presence of mains or Gen) viperVIP: 1 Like |

Re: Solar Energy, A Complement To FTA by viperVIP: 10:26pm On Mar 06, 2023 |
Thanks boss. That's an eye opener, read about it on this thread before but didn't come to mind when the need arose. I've checked earlier and found the XHM6 with lower current tho and just checked again now, I'm able to find the DC relay which would work perfectly for the purpose. Just that the cancelation of naira cards for use on aliexpress makes it discouraging for ordering these petty components. The concerned system is a Must 1kw Hybrid Inverter connected to solar & a lifepo4 battery. The Inverter does not shut off when it reaches cut off voltage, it only cuts output, then drains the battery till the BMS is put to sleep. so I'm considering sending it for repair, then deploy a 1kva inverter & mppt charge controller there, but would need to cut the 1kva inverter off at 12v or else would drain the battery to 10.8 and BMS is set to sleep at 11.0v. The system is not connected to grid or generator, only solar. Thank you NiyiOmoIyunade: |

Hello all the Gurus in the house. I need your guide please. I have a 60ftx30ft hall for my poultry and I need to use solar for the lighting. I have 2 pieces of 80watts solar panel. I have some background knowledge of solar system design. I have decided to use 10 pieces of 5-7 watts DC bulbs. Please kindly help me and suggest the type of battery I should go for, it's capacity and where I can buy. Also the DC bulbs and charge controller. NB: I need the system to light my hall for 10 hours. Thank you. |
Re: Solar Energy, A Complement To FTA by durodee(m): 1:27am On Mar 08, 2023 |
Battery type is not the first problem here. There is harvest versus usage disparity. Your panels will generate @ 600w/day under the best conditions. Yet you plan to use 500-700w/day. Chances are that the days in a year that you will meet your 10hours need will be few unless you change your calculations or expectations. manya: |
Re: Solar Energy, A Complement To FTA by manya(m): 7:31am On Mar 08, 2023 |
durodee:Thank you for your response. Then if I am to add yet another 80 watt panel, what spec of battery will be suitable for me? |
Re: Solar Energy, A Complement To FTA by Valto(m): 8:57am On Mar 08, 2023 |
manya:for 10pcs 7watts bulbs =70w. u need a 12v 200ah original battery /12v 120ah lithium battery. atleast 6pcs of those 80w panels in parallel to charge your battery faster. |
Re: Solar Energy, A Complement To FTA by ojesymsym: 10:02am On Mar 08, 2023 |
Since you are going DC, which I am glad you are doing, buy the battery you can afford to get started. If you can also design it in such a way that some of the bulbs get triggered when the birds move, I believe that will help conserve some power. Another option is to break it into 2 circuits, that is to have 2 independent systems just to share the failure rate across the 2. manya: 1 Like |

If you are getting intermittent overload errors on the inverter when there are apparently no loads on then that is clearly a wiring issue. Apart from crossed neutrals consider the possibility of some wires on the load side shorting together from time to time - degraded insulation, water ingress into external lights, faulty equipment e.g water pump or other device shorting internally (what local electricians call a 'back feed') are likely causes. These kinds of problem typically require some inspired troubleshooting to narrow down else it may be a long and bumpy ride. If you clearly have a wiring issue then using AC Out #2 will not address that. Trippledots: 2 Likes |

manya:Let us assume 700 watts usage @12v = @60 amps. Is your 10hours usage going to be at night only? If so all the 60amps must come from your battery. You will need about 70- 100amps battery if lithium, or as 150amps if lead acid to ensure about 50%DOD. The rest is your choice and pocket. By the way, nothing says you cannot use car battery meanwhile before you gather your self for a good deep cycle battery. |

Questions for my friends, whose panels are on the rooftops, how do you adjust for optimal yield from the sun? Mine is on stands on the floor and I have been able to play with positioning to achieve optimal yield. https://www.youtube.com/watch?v=mmewJlpC1MQ

Re: Solar Energy, A Complement To FTA by adrusa: 12:44pm On Mar 09, 2023 |
For the felicity crew in the house, I need some help and information. I bought a new 120A Felicity Charge Controller yesterday, but it appears to be working differently from the previous one I have. I expect the Charge Controller to come up when I connect it to battery, but it does not. It only came up after I connected the panel. However, once it is dark, the controller died again. It woke up again this money once the sun came up. The previous one wakes up even in the middle of the night when I press the on/menu button. Can anyone with recent Felicity Charge Controller please share their experience with me. Thanks. |
Re: Solar Energy, A Complement To FTA by TechGeek777: 1:00pm On Mar 09, 2023 |
From recent videos I have watched, they said latest/recent Felicity charge controller are built not to take power from your battery at all, this means you can only use the CC when there's pv available. Also, when there's cloud The CC will be showing fault mode if the pv is not sufficient to power the CC. At night the CC WON'T display at all, and from the videos the CC wakes up at about 7am. So your CC is doing perfectly fine. The motion is to conserve battery. All modern Felicity CC now have this feature embedded. adrusa: 1 Like |
