Obimind1:Did you get in touch with Epever? If you got it brand new. Get in touch with them they are quite responsive and do honor their warranty. I know a friend on here who had similar issues with his Epever and I have seen couple of post online too. All where resolved sha. My first controller was a Epever RN series. The meter developed a fault (which didn't affect the controller or charging functionality at all) besides that never had issues with their controllers. |

kiekie1:I didn't mail epsolar. I noticed that the problem was with the board of the mppt which is the heart of the cc. If there is any way I can reach ep solar, honestly I wouldn't mind. After all they is no crime in trying. A member on this forum told me how his board was changed and his epsolar came back to life, but the truth there is that he bought his own ep solar cc outside the shores of Nigeria. I don't know if their warranty really works in Nigeria. |

Obimind1:They do respect their warranty even here in Nigeria. I once had issues with their controller (The meter) and they resolved the matter. You just need to send them proof of purchase and answer their further question on the problem. |

Reprobate: epSolar changed my iTracer IT6415ND when I promised to ensure their products become unpopular on the market. Neither middleman nor importer were able to help when my first unit went bad. Decided to liaise directly with the parent company and make direct calls to the sales manager and tech support manager. A friend was in China so a replacement was sent through him. Bought numerous units thereafter. The closest I've had to a problem after the initial one was one with a fading display unit. Proved to be a pretty reliable brand (does marginally over-report harvest and is slower to scan the array than premium brands). Would I buy another unit? Oh, I recently just got another for a friend! Will anyone in this country honour the warranty on the label? Most definitely not. Why not? We don't hold them accountable. In my case, it became easier to deal with officials halfway across the world than people in Lagos. 4 Likes |

liquidcrystal73: There's something which might be worth the try. Let's offer some free advice from personal experience: I had a similar problem once. It was the unit I gave my dad. No amount of troubleshooting would make it work. No error asides that a seemingly bad controller. I remembered MPPT usually requires varying headroom to work. The kicker? The CC had been working perfectly for about 6 months. Anyway, I increased the string size thus VoC, from 38V to 76V (for a 24V nominal bank). And that did it! Why? Heat and dust usually lower VoC in harmattan. And MPP is significantly lower than VoC. The incoming voltage difference just wasn't enough to drive the MPPT of the CC. For fun, a few months later when the rains began, I reverted the connection and the CC kept working (VoC was higher). Summary: if your CC allows for up to 100V VoC, I recommend running your panels in strings of two. Let's see if it makes a difference. But save that for a last resort fix. For now, trouble your warranty guys. If possible, let them do the workarounds with you. They should come with their own fix-it crew to prove whatever they need to. ![]() |
Re: Solar Energy, A Complement To FTA by Saipro(m): 4:53pm On Nov 02, 2017 |
liquidcrystal73:Sorry for my late response. There are other options to explore before having someone tinker with it. I'm particularly sceptical of having devices which can go up in flames being tinkered with when I can't see what's being done. True to form, I take snapshots of all panels and components on their way to and from the fix-it shop. Otherwise, a replacement is what gets me sleeping with ease at night. 2 Likes |

bigrovar:The voltage difference could be all the problem liquidcrystal73 is experiencing. Sorry for the repeat reply but I'm reading and replying along. Been away a while. GeorgeD1:I wouldn't quite say over-hyped. Let's just say MPPT isn't for everyone. And it definitely isn't for every installation. If your batteries and panels are closely matched in voltage and transmission distance losses won't have you buying cables thick as your wrist, by all means, PWM all the way. Especially for arrays less than 2kW (definitely for arrays less than 1kW). The pulsing helps prevent sulphation in ways you hardly read of. Asides other smaller advantages. In fact, if you have all the aforementioned factors going for you and you have space to place more panels, use the cash difference to procure more PV panels. Of course, you know why PWM won't make sense when you go over 2kW of PV panels. 1 Like |

Re: Solar Energy, A Complement To FTA by pranil(m): 5:24pm On Nov 02, 2017 |
Saipro: I fully second that opinion For MPPT always try to go higher than battery voltage( Absorb setpoint) by at least 5-10 Volts to ensure charging in low light conditions. But also note that there is no extra advantage in going higher than required. All the charge controllers are less efficient at higher input voltage although the difference is few percentage point not so visible in small installations e.g. attached is the efficiency curves for EPEVER at different PV voltages 1 Like

Re: Solar Energy, A Complement To FTA by Saipro(m): 5:38pm On Nov 02, 2017 |
pranil: Recess suspended. The phrase in bold is crucial in small installations. Do not forget that. You could lose way more in transmission losses while trying to get the optimal PV voltage. Dependent on nominal bank voltage. For 48V, you need up to 20V headroom for many controllers else you'd have inexplicably low harvest till the sun is way up in the sky. For 96V, at least 30V. I tried firing up a nominal 120V bank with VoC of 160V. Of course it didn't charge one bit with MPPT. Made me laugh. ![]() Been doing a lot of toying around lately. Stuff you wouldn't read in books. I'm sure you're doing the same. Regarding efficiency, it seems most of the loss is due to heat loss from the conversion process (CCs run hotter the higher the conversion potential difference). Necessary for long wire runs or large PV arrays. I downsized my bank voltage to 24V (rearrangement) recently to keep a straying battery in check. My Midnite Classic has been buzzing like a bee since then. ![]() |

My Oga's in the House, I bow. 1. A client just bought a 2000kVA Gas generator to run his manufacturing plant. He presently uses a 1500kVA gas gen to run his existing facility. 2. Now, since the new Gas gen has not yet left for Nigeria, he is asking me to propose a solar system so he can consider cancelling the purchase and instead channel the funds towards a massive solar system. 3. Now, I have perfected the Solar array and battery bank design but I am having issues with finding an inverter brand that can do the job. I know finding a standalone 2000kVA inverter may be tough so I am open to cascading multiple units to attain the total kVA I seek. So far, all the inverters I am seeing are Grid-Tie. Hence, since we all know the Grid is as good as non existent, they won't work unless I begin to explore doing AC Coupling with them. I have checked out SMA but most stuff I see there are Grid-Tied. Please help will be appreciated. |

@Saipro . . I saw your comments and thoughtful, they are! But unfortunately, didn't work in my scenario because it was only powering a 12V system and at failure, the voltage coming from the panels were about 18v roof-line The CC wasnt delivering amps, which meant zero charge but yet, it was raising the battery voltage from 13.7 float to 16V and the CC would disconnect with an OVD (over voltage disconnect) warning !! The warning stayed put, until i manually disconnected the CC from Panels via the breaker. Battery voltage went back to 13.8 thereabouts (float) On flipping the breaker back to the ON position . . . whilst zero amps still displaying, CC would raise the battery voltage again to 16V, creating the OVD warning again. Until I brought out the PWM to the rescue. Update: Spoke with the Engineer who said he had fixed it.What he did to fix it, I don't know but he confirmed it was now working perfectly and he has test-ran it with panels and batteries and all is fine. How long it would last, I do not know. Would my house blow up while I am asleep . . . Only God knows! The Engineer said his charge is 10,000 Spoke to Kiekie and said I can only pay 6,000. Take note: 10,000 is seemingly too minute an amount to lose sleep over; but Kiekei1 has to man-up and take responsibility too. So being a very nice person, I only offered to pay 6,000 to the Engineer If the Engineer refuses to accept it, KieKie would have to balance him 4,000 or he could speak to his Engineer to accept it (they are friends) But Kiekie would go on to narrate how he blah blah blah and blah . . .and yes, he talks too damn much for a man! For someone who claims he is very busy, his calls are nothing less than 15 minutes at a stretch. He went on to narrate how "he killed a chicken, and the chicken resurrected inside the soup . . and he killed a bird, and the bird's mom flew away' . . SMH seriously! Well, I called the engineer again and he said, he wont accept 6k, obviously Kiekie didn't want to balance the 4k.. . so he said, he will accept 8k I said OK, send me your bank details, he has sent it and I am going to pay him now. I have arranged a courier service to go pick it up from his office and make an express delivery to me. If you add the total cost spent in sending it to the engineer, paying him and sending it back to me .. It would have gotten a 60A mppt of Aliexpress and or a 40A one on Amazon and I would have had rest of mind about warranties. As a prime member that I am on Amazon, I only need to send video proof and get a replacement without returning the bad item. So I tried to be penny wise, and ended up being pound foolish. Would I deal with Kiekei again? Yes, only on items 2,000 and below. Would I recommend him? NEVER Is he honest? NO, whilst appearing honest, he is sly, shady and self-centered. Does he like to refund or share the bills? NO Does he want your money? YES Is he talkative? YES If there are any other updates, i will share thanks.!!! 7 Likes |
