Best to spec with the usual and when the unusual happens you ration the use of your battery. Your can reach me on o 7 o 6 double four double five 9 43 if you want me to assist. My guess is you want a budget package. hooryo: |

As a contribution to the ongoing solar panel energy production debate, which many with monitoring system can attest to is. For us a rule of thumb, 1. Tier 2 panels are calculated with 0.55% of nameplate or total PV capacity for period of 4 Hours. 2. Tier 1 panels are calculated with 0.65% of nameplate pr total PV capacity for period of 4 Hours If the system is loaded I.e. energy storage and loads then it is expected to see energy production in line with above. This proven true by remote monitoring. Conditions based on a normal sunny day 5 Likes 2 Shares |

A quick insight to your project To lay it bare, your appliances are not efficient even if you try to manage it, they won't help at the long run & a quote will look bogus for these little setup Proffered solutions, if possible when choosing to go solar 1. If a 12V TV with adapter can be used ... It will be a great alternative 2. Forget the fridge use it only with Grid supply 3. Use only TV speaker, forget the speaker too 4. Don't have idea of the bulbs but since it is a room, changing them to 5 or 3 watts and using only two at a go will go a long way to minimize yoir setup 5. If you can get them DC fan of 30W max. That will be good for your setup 6. Say your neighbor have 3 lamps to charge i.e. 9W x 3 and phone charging say 12W x 4 phones. That's 18W + 48W =66W for say three(3) hour period - 198Wh ( when you decide to go solar then only a device per person is best allowed) else your battery go hear am. Conclusion With a TV - 60W+ bulbs 10W+ decoder 20W + fan 30W = 120W for 5 hours is a 50% Dod for 100Ah battery So a 1kva 200Ah Solar system with these new aforementioned suggestions, & your 10 hours of GRID supply should keep your going for 24 hours of power with no interruption. (Your neighbor charging wasn't included) hooryo: 2 Likes |

Please I need a good Solar Inverter technician to inspect my solar set up around Mowe. I don't seems to be getting an ultimum charge for my set up. Any reliable contact please? |
Re: Solar Energy, A Complement To FTA by ohchacha: 11:52am On Feb 22, 2022 |
I'm pretty sure that with decent batteries, it's not a problem to run your whole house on solar energy. Also, I have a 2000 watt inverter just as a source of backup power in case of emergency, and it really saved my life a few times. So in general, I don't see any reasons why someone wouldn't like to cut their electricity bills. 1 Like |

FireTheSun: Holy Molly. I hope those are not LiNiMC cos those are worse off; typically comes with class 3 fires that are much more challenging to extinguish with your typical fire extinguisher cos it literarily does not require oxygen to burn. If it's LFP well, it will still be better. |

mrlien: you know the old mustpower or prag...inshort any 3kva to 5kva inverter above 26kg is most likely old technology - transformer based..and would have a high idle consumption. like the 4kva of the attached..consumes 130watts just for being on, zero load

Re: Solar Energy, A Complement To FTA by rajo4real(m): 3:42pm On Feb 23, 2022 |
Please i need clarification on how best to carry out a capacity test. I ran two sample capacity test on 3.12KWH lithium ion pack Test 1: Inductive load using freezer consuming 350W lasted for 4hrs(battery was on 23.6V but when load is off, battery goes back to 25.6V) Test 2: Non inductive load of 250W lasted for 9.5hrs(battery was on 23.9V but when load is off, battery goes back to 24.6V) How best can i deduce battery capacity since am yet to get a coulomb counter. |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 4:04pm On Feb 23, 2022 |
rajo4real: the pack is likely a locally made pack?..its either wrongly badged or defective/unbalanced cells are inside. do you have access to communicate with the internal bms? the 350w load shud have done 7 to 8hrs., while the 250w should have done 10 to 11hrs...it did 9.5hrs...fair enough. is the pack sealed?..can u send a picture of the internals..if possible |

Is this battery a good buy. Someone wanna sell for 50k each he claimed they are fairly used 150ah each

Re: Solar Energy, A Complement To FTA by rajo4real(m): 4:43pm On Feb 23, 2022 |
earthrealm: Oga earthrealm, the pack is a DIY pack which was locally made by me with a cheap BMS slapped on it to test. The cells are fairly balanced but what am not clear with is battery is fairly ok with non inductive load but performs poorly on inductive loads. What could be the issue? |
Re: Solar Energy, A Complement To FTA by Valto(m): 6:14pm On Feb 23, 2022 |
Michaelondon53:fairly used batteries na black market, what u see, is not always what u get. your best bet is to demand for a one or 2 weeks guarantee from the seller, that will give u enough time to throughly test it. 2 Likes |
Re: Solar Energy, A Complement To FTA by mctfopt: 8:38pm On Feb 23, 2022 |
Michaelondon53: The brand is not a bad brand. I've, once upon a time when lead acid ruled the space, used 4 numbers of 200AH of same brand which was fairly used and it lasted for 3 years plus. I got lucky as the one I bought was truly fairly used. I can't say if the one you want to buy is truly "fairly" used or "brutally" used before being sold. I'll recommend getting a good guarantee (something like money back if after two weeks you don't like what you see). But I know this type of warranty is like selling ice cubes to an Eskimo , e hard ![]() 1 Like |

[Quote author=olopan post=110434089] As a contribution to the ongoing solar panel energy production debate, which many with monitoring system can attest to is. For us a rule of thumb, 1.

Tier 1 panels are calculated with 0.65% of nameplate pr total PV capacity for period of 4 Hours If the system is loaded I.e. energy storage and loads then it is expected to see energy production in line with above. This proven true by remote monitoring. Conditions based on a normal sunny day [/quote] I have been taking logs of my solar installation since 2017 over 80% of those logs collects real time to information every 10sec of panel generation including peak power and total generated energy for the day. What I have come to understand is, a lot goes into your solar panel harvest than just being tier 1 or tier 2. The most important thing is how the panels were installed. What is the angle of inclination and the direction the panel is facing. What is th installation design. Does it flush with the roof or is it installed on a roof rack. Lastly Location location. A solar panel installed in jos would have a different average yield compared to one installed in calaba. A well optimized panel installation beats a tier 1 panel installed "wrongly" Here are key pointers. Ensure your panels are installed as flat as possible. Nigeria is just above the equator so your panels so the flater your get your panel the better. 7°horizontal tilt facing through true south. Send down the rain type of roof you see in many "mansion" in Nigeria are not ideal for solar. As much as possible avoid your panel facing the north of you have no choice then make it as flat as possible using the roof rack to offset the non ideal roof angle. Best to avoid mounting your panel directly on the roof. The roof is the hottest part of the house and heat is the enemy of solar generation. In fact panels derate the hotter it gets and you can lose close to 10 to 20% of your generation due to heat. Mounting on a rack that elevates the panel above the roof allows for it to be air cooled and reduces heat transfer from the roof. If you have a large compound consider ground mount but ensure they are no partial shading. Ground mounts are best. Your panels can be tilted optimally, can be easily cleaned during the dusty period and easy to earth them. Wiring is also very important. Lots of losses can happen between the panel and charge controller. As much as possible strive for higher voltage configuration to avoid pushing too much amps down the wire. This is one of the beauty of MPPT. It allows your to string your panel into higher voltage strings thus reducing the need for large wiring and associated cost between panel and controller. Note that the thiner the wiring conductor surface area the higher the resistance and losses. There are lots of site that that help calculate how to size your wiring relative to amps/voltage and distance. If your panels are far from your cc, you need thicker longer cables or you might want to consider a controller that can table high voltage panel Strings like 250v and use that to reduce loses and wiring cost. In all, it is very reasonable to get 70% or even higher from your panel if the condition is right. My 3kw panel does 2500w standard as need demand and as weather permits. It is however good practice to size your system in the design stage with conservative figures just ensure you thrive to beat those figures in the actual implementation. 14 Likes 3 Shares |
