pranil: It was me. Thanks for the insight. We got the inverters as a donation from a government agency sometimes in 2016. The error made me lose confidence in the durability of the ipower / axpert inverters. |

olagunju2000: Everyone has said their piece. All pretty informative. While my 3kW array has given up to 16kW/day on a number of occassions, I typically get between 5kW and 8.2kW these days with occasional peak spurts exceeding nameplate rating. I have premium grade panels, batteries, CC (with Wizbang Jr. shunt) , inverter and cabling. So we ask, what has gone wrong? Nothing! I significantly cut back on opportunistic loads. Your batteries have a limit they can take! Your daily charge represent prior consumption + a little extra (consumption including those of the CC, inverter and transmission/conversion losses). You really can't force it and when you do, you ruin your bank by boiling it to death. The whole idea in massively oversized PV arrays is in being able to run opportunistic loads during the day as well as having a lot of reserve for cloudy days. I rarely exceed 1,200W steady production these days. Toggle a few switches and it jumps to 1,900. Considering the heat, dust (haze) and 77% NOC yield, everything is intact. In fact, I'm more than impressed. (Makavele, Pranil and Bigrovar seem satisfied too). Abunafiu and I, living in close proximity and having similar setups, have often compared data and they match. CCs at times report slightly different values but when in doubt, whip out your trusty (translated as quality) digital readout equipment and verify the data. I hope you're aware that panel performance degrades gradually with the greatest drop occuring within the first year (seen up to 8% for JoySolar panels, 2-3% for good/premium brands). Lots of other variables to consider. We can all allude to different causes and ask for all kinds of data but a site inspection would be ideal. The very least (as Pranil and NiyiOmoIyunade suggested) is checking both the individual panels and the conections between them. Your professional didn't do a professional job; cable connections/termination is a big issue in elctronics (cost considerations?). On the choice of charge controller, I'm with Abunafiu on that one - Midnite Classic all the way! My two kobo. 3 Likes |

olagunju2000: Good man! I'm loving your installer already |
Re: Solar Energy, A Complement To FTA by Saipro(m): 10:07am On Nov 29, 2017 |
NiyiOmoIyunade: Thanks for the reference. Been a bit busy lately so I'm somewhat irregular on the forum. I'll be popping in once or twice a week. There's really nothing wrong with the OutBack. Splendid equipment worth every dollar. Possible downside is fan failure. The Classics for all intents and purposes are OutBack FMs built with a future perspective and a host of other enhancements. Let's just say the Classic is the one edging its predecessor out. The Magnum is great but a bit pricey. It came straight from the lab thus each production batch seems to have an edge over the previous one. Solid firmware support (according to the company) and 100A @ 48V is no joke. You could roast an whale with such currents. 2 Likes |

Dam5reey:PWM excel under the conditions you've given. He's referring to an MPPT (with conversion losses). More isn't always better. I am sorry I revisited this but my conscience kept pricking me. 1 Like |
Re: Solar Energy, A Complement To FTA by Dam5reey(m): 10:20am On Nov 29, 2017 |
Saipro: Conversion loss, should be negligible in such an array set-up.. also note he was asking about 1 panel not the whole setup |
Re: Solar Energy, A Complement To FTA by nasonaso: 12:23pm On Nov 29, 2017 |
pranil: Thanks pranil. I do appreciate. I notice also that without the input wire in the inverter. if you read the input of the inverter it reads on the multimeter. I was thinking aloud could that be the reason the inverter fails to automatically switch to inverter mode when there is a cut in power from the mains? |

bigrovar: Older ipower are 3 years max ![]() the newer model is more robust but PV has to be Grid panels in series atleast 11 of 250 Watt https://www.mppsolar.com/v3/pip-ge-series-high-pv-volt/ |

pranil:So the newer Ipowerplus are same as newer models coming from. Axpert / mpp solar? And damn.. How do this people do it. I would keep my fingers crossed and see how well the new models perform over a period. Chinese Taiwanese are known for cutting corners which might end up affecting durability. |
Re: Solar Energy, A Complement To FTA by JohnKester: 8:28am On Nov 30, 2017 |
NiyiOmoIyunade: I would go with the Morningstar too. Apart from the already stated reasons, in the event that you want to expand your array, the second CC will make that possible without the need for a second CC as would be the case if Midnite were used. Since the Midnite is already maxed out, you will need to get another controller for future expansion. Cheers |

I have a few units of a GSM controlled programmable(by text) switch rated up to 30Amps AC. It also gives feedback on status of power. Includes timers and can accept input from multiple numbers. You may find a use for it. https://www.nairaland.com/3650081/remote-gsm-switch-access-controller. Thanks 2 Likes |

Dapsyra, Do you still enter your production data to pvoutput.org manually or you've found a way to automate the process? |
Re: Solar Energy, A Complement To FTA by dapsyra(m): 4:10pm On Nov 30, 2017 |
I am still searching for a way to automate the process. The classic 150 automatically upload the data to MyMidnite website every five minutes, I then download the CSV and upload to pvoutput website after sunset. Let me know if you find a way around. |

bigrovar: I am using 2 in parallel and kept one in stock in spare and cost me 750 K for 10 KVA/8KW( with one spare) against victron 10 KW 2 million . + 2 charge controller 500 K . + BMV 70 K + CCGX 200 K ( almost 3 million ) I would rather change every 3 years then invest that kind of money of course the main house runs on Victron ![]() 2 Likes |

dapsyra: use the android app- https://play.google.com/store/apps/details?id=ca.farrelltonsolar.classic&hl=en ( use either a cheap or spare phone) or use Blustack on windows to run android app https://www.youtube.com/watch?v=CbjlrrsU8T4&feature=youtu.be |
Re: Solar Energy, A Complement To FTA by bigrovar(m): 6:09pm On Nov 30, 2017 |
Barezzi: Get a $30 raspberry pi if you have knowledge of Linux you can attach it to a USB dongle and have it upload the csv or relay the data real time. There are lots of python scripts online that can do this using pvoutput.org API. Nothing too hard if you set your mind to it. |
Re: Solar Energy, A Complement To FTA by dapsyra(m): 6:31pm On Nov 30, 2017 |
pranil: I have that app already. It only upload daily summary not 5 minutes average data. |
Re: Solar Energy, A Complement To FTA by dapsyra(m): 6:32pm On Nov 30, 2017 |
bigrovar: I intend to go this way when I am less busy. Thanks for the suggestion. |
Re: Solar Energy, A Complement To FTA by babaegun(m): 6:56pm On Nov 30, 2017 |
bigrovar: dapsyra: @dapsyra If you can extract the api´s from the midnight classic website, then it is a piece of cake cause thats exactly how i upload to pvoutput.org. I pick the api´s from emoncms and upload to pvoutput.org You´ll need a raspberry pi, install php on it, internet connection, schedule it on crontab and voila, you are up an running with your live data. |

abunafiu: The Raspberry Pi is a tiny and affordable computer that you can use to learn programming through fun, practical projects. it is just $35. Bought mine (2 pieces) on Aliexpress. One permanently connected to my Fangpusun CC to get the solar data which is automatically uploaded to emoncms. The second one I use as my desktop computer at home. It uses less power and wonderful for a solar setup. https://www.raspberrypi.org/ https://en.wikipedia.org/wiki/Raspberry_Pi |
Re: Solar Energy, A Complement To FTA by Barezzi(m): 9:23pm On Nov 30, 2017 |
pranil:Does it also capture data from Midnite Classics? |
Re: Solar Energy, A Complement To FTA by dapsyra(m): 9:55pm On Nov 30, 2017 |
babaegun: I can actually capture the data directly from the Midnite Classic CC via Modbus using Raspberry Pi without recourse to the Midnite website. I have not just gotten around to doing it. |
