mrmachine: The MPPT charge controller appear to be iPanda or POWMR or whatever name the seller wants it to answer ![]() ![]() The MPPT is not a bad one. But as for the solar panels and lithium batteries, I can't really tell of their quality, but going by the seller slapping their name on generic brand of an MPPT, the solar panel and lithium battery could likely be just another generic Chinese brand whose seller is willing to slap any name you want on it. |

mrmachine: the 'xtrapower' brand doesn't seem to be among the regular brands we are familiar with. it might be a new kid on the block trying to gain market share or might just be a white label. either way, i'd be careful if i were you because given its obviously unknown history it would be acting in blind faith to throw hard earned money at such product range. |

Thanks. The man boast of their MPPT charge controller as its almost priced like some of the premium ones I used to know. The 100A goes for as much as 200k. And he is also willing to stake a good warranty on the products. I am just being careful not to make mistake. I would give their panels a trial and update the house mctfopt: |

Mustiboy: The first comedic act of your installer was the 260w panel for all the listed loads. Then boom, another one. Dude connected the solar panels directly to the battery, bypassing the CC. OMG! ![]() Bro, you gat yourself a "solar expert" o. And one with American wonder for that matter. Your 260 watts panels x 2 should do a fair job at fully charging the battery since you do not have loads on it while charging. Your 3 hours backup on your 100ah battery of 150 watts load is also expected more so with the likelihood that such a "solar expert" may have used suboptimal battery in your installation. So with the problem of inadequate power from the panels, you should do the following: Be sure that the 260 watts rating on the nameplate of the panels is indeed the real rating and that he got you new panels as you required and not used ones. Even used tier 1 panels will give good power output in the first instance. The guy may have excised the MC4 connectors of the panels and do a direct (wire twist) connection for the whole process. Long term viability of such connections when exposed to the elements can not be guaranteed. So one of the panels may have disconnected, or the contacts grossly inadequate to pass current. Check the direction of the panels for adequate insolation. I would wager that a "solar expert" that for a moment considered "connecting panels directly to batteries" will likely not know that there is a concept like "proper panel orientation" to be considered. For all you care, your guy may also have connected both panels in series and sent that output to the PWM CC like that. 260 watts panel has a nominal of 24 volts and can only be used with a single 12v battery when you have an MPPT controller (not PWM controller) or at worst a buck converter between the two (panels and battery). So either parallel panel connection o or series connection o, the use of PWM with your single battery on a 260w panel (if the panel is truly 260w and not rebranded 150w) will bring up problems like you're experiencing. Review your cabling too. Your guy may have also used terrible gauge wires for cabling at every stage of the installation. Having said all that, it seems your battery is still viable (if the direct connection to the solar panel has not fried it yet). Then let's assume your panels are as true as rated and that connection on the roof is adequate. Then your best bet may be getting an MPPT as opposed to "downgrading" to new 150w panels or as opposed to getting another 160w panel that will still be connected to an already faulty mix. There are inexpensive but reliable MPPTs like PowMr that @ Odimanbadi listed here for around 52k. I think a picture of your set up uploaded here to give guys an rough idea about your system will be of some help. 6 Likes |

Mustiboy: The summary of what everyone is saying is that your installer has shown poor knowledge which has resulted to a poor job. However it could be easily fixed by someone who knows what they are doing. My advice is you try and reachout to the guy here who offered to help you earlier. Penuelseun: 2 Likes |

ceaser: You wouldn't know how much I appreciate your detailed explanation, Sir. Thank you very much. Yes, it's sad that I didn't know about this thread when doing the whole thing. I've heard and seen peeps get longer hours on a 100a battery. Don't know why mine is different. When I complained about the panels to the installer, what I told him was that I don't expect two panels to perform miracles, but I expect it to be able to keep the battery charged when it's sunny if it had been charged fully with NEPA overnight. Also, I don't have any load on the inverter most of the time. Just bulbs, charging of my gadgets, a single fan, and 50w TV once in a while. That's not too much to ask from two panels, and it should be able to charge the battery fully with 6 hrs of sunlight. A Nairalander even called me yesterday to explain things in details to me. I was shocked about how much I had been living in the dark. Yes, I've removed the panels connected to the battery as people have instructed. I've been told what the panels need is resolution or reorientation, don't know the right term for it. Will get on with that by Monday. I'd appreciate further input from you Sir. 3 Likes |

Dishtech: Good morning. Merry Xmas to all solar enthusiasts!!! Please what will make a two 100AH batteries connected in parallel last less than 4 hours with load of 16% {i.e 160watts) on a 1kva inverter. Though it was up and running since morning when the sun was up and turn off by 5pm to conserve battery for usage at night when the charge controller read 12.8v.doesn’t that show that the battery is full for usage at night? Why then less than 4 hours with inverter red light blinking after 3hrs 55mins? |
Re: Solar Energy, A Complement To FTA by gadgetplanetng: 7:08am On Dec 25, 2021 |

Re: Solar Energy, A Complement To FTA by Michaelondon53: 7:19am On Dec 25, 2021 |
Michaelondon53: Also I don’t know which component is lying maybe the inverter that doesn’t know how to calculate simply or the lonton company with all their crazy nos of watts inscription on their bulbs. My inverter load last night red 16% I.e 160 watts of a 1kva with just tv of 70watts, one 12watts bulb and one 5watts bulb. Inverter took 30watts running on the battery. Calculating that should amount to 70+12+5+30= 117watts!!! Why then is the inverter reading 16% (160watts) where did the 43watts come from??� |
Re: Solar Energy, A Complement To FTA by Dishtech(m): 7:37am On Dec 25, 2021 |
Michaelondon53: 1. How many panels do you have? 2. Depending on your panel position by 5pm you may not be getting much current to charge them and if pwm charge controller. 3. Charge well without using it or with NEPA to see whether they will be difference 4. Check the battery individually whether one of the two is bad. That is why you would have used a single 12v/200AH to avoid balancing or wrong connections. |
Re: Solar Energy, A Complement To FTA by Dishtech(m): 7:45am On Dec 25, 2021 |
Michaelondon53:Note that your appliances are rated in watts not VA, dividing by power factor to get approximate VA or convert the 1kva to wattage is around 750-850w depending on the inverter power factor. |

Michaelondon53: I suspect your batteries may be half dead already, are the brand new?..brand new?. top tier battery?. has the performance always been like this? if you have a digital voltmeter....connect a 400w to 600w on the inverter for like 2mins..and quickly use the voltmeter to read the voltage of the batteries. do this after the batteries are charged full............. 1 Like |

Re: Solar Energy, A Complement To FTA by Dam5reey(m): 10:25am On Dec 25, 2021 |
Michaelondon53: The problem I noticed here is that you don't know 1. Your inverter Idle consumption 2. Load consumption. First step when going Inverter Route is KYC (Know your Consumption Energy) Get a DC Energy meter to calculate your energy usage directly from the Battery.. They are not Cheap, Around 10k plus shunt with this you will know the consumption as well as the Battery capacity... Your 100AH might not be 100AH too.. or used cell Also those Inverter 16% or load are not Accurate.... |
Re: Solar Energy, A Complement To FTA by islamics(m): 5:01pm On Dec 25, 2021 |
Hello, Didn't know about this thread. Was searching for some stuff and it came up. I just setup my own with a 200a battery and a 1.2k inverter. Though I am yet to get panel as I intend to be using nepa for the main time. My load is TV, decoder, laptop and 28w for bulbs. No fan yet, hope to add DC fan and fridge soonest In Sha Allahu. My question is that my TV does not power/boot completely with the inverter stuff but work well with NEPA. Is there any suggestion to solve it? Earlier this year, my TV capacitor got burnt from power surge before I put stabilizer in the house. I haven't replace it as I intend to use company warranty stuff for the repair and the procedure/period of repair might be long. |
