eleojo23: Multichoice will very unlikely offer you a CI card cos it may eventually backfire on 'em. It is an easy way to bypass their subscription for those that know their ways. You can get it from those guys that install subscription TVs like Startimes and DSTV. They will also help you set it up including the dish direction placement and every other stuff about it. |

Oshomo12: My brother, I no know nau. European TVs are usually spec'd much better and with superior quality than their African counterpart even for the same manufacturer and model number. So I wanted that high spec'd device too. I thought it will be a fair experience like buying tokunbo vehicles. I no know say na express my masquerade dey go. eleojo23: If one will be constrained to get tokunbo TVs from Alaba, then maybe it'll be wise to choose products such as Sony, Toshiba et al which have slim chances of adulteration. The LGs and the Samsung's to a lesser extent seem to be an easy clone for those Alaba TV merchants. I was expecting something that will be as mint as tokunbo cars that we buy here but was shocked when I was confronted with multiply scratched case, torn label and changed label that the model written on it has no semblance to the model number I ordered for. It was when I switched on the TV that I now saw the correct model number. I mean it's as if a wrong engine was placed in a different chassis altogether. Time to operate it and both You tube and Netflix started acting up with blurred video images and with muddled colour gamut when using both application. Same problem applies to phone to screen mirroring. It didn't last 24hrs on my TV shelf before I had it shipped back to the vendor who in his best sense felt he would return money short of 30k. I no even get strength for arguement. Na me dey look for European spec TV when I could have jéjéli manage the mediocre but brand new Subsaharan Africa-Nigeria specs that is usually dumped here.

28 days uptime boss. What flavor of Raspbian are you using? That seems like some impressive stability. In my case the Python scripts I run (6 times per minute) sometimes hog ram and the system freezes up - I have a separate background script that reads free memory and reboots the Pi if it falls below a threshold so SSH and other services can stay running. I use all Raspberry Pi 3B+s running either EmonPi or NOOBs litaninja: |

You can easily flash new firmware onto the inverter that avoids this bug entirely. You can also send commands over serial that may achieve thesame result. I recently had a Steca 5kva go out of calibration with its voltage readings. I simply recalibrated it by sending commands over serial. ojeysky: |

I am running Pi 4Bs 4GB running Raspbian 10 Buster. Just direct installs via imager without NOOBs. 6 times per minute? Hmmm, does that give the scripts enough time to run, terminate & return resources properly to the system? As most *nix are quite stable and are expected to go months/years without a reboot. Also, the monitoring package I'm using is sitting on docker, that would help stability as well. NiyiOmoIyunade: |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 8:26am On Oct 15, 2020 |
NiyiOmoIyunade: Right if there is such firmware that has the bug fixed, for those using the MPP MK series there is a custom firmware for that. However i use the GK series and for other clones like felicity and co there isn't an appropriate firmware (or I have not seen one)
Yeah one can do that as well and then put a Cron to automate the process. Using solpiplog is hassle free for me since I already hervest my data through it anyway. |

You are basically substituting external control from a Raspberry Pi for a function the inverter should natively perform. I fear for the stability of such a system if the Pi fails or randomly loses comms with the inverter. In the Victron world, the GX (essentially a commercial grade Raspberry Pi [Beaglebone] with two failsafe partitions) is also an external control mechanism. The difference is that the GXes are battle tested to be super stable (reliable comms, recovery scripts and 2 working partitions) and also Victron forces you to properly configure the MPPTs and inverters that the GX will control, if the GX goes offline, the MPPTs stop charging and inverter switches off too. You would have to manually factory reset the MPPTs and disconnect the inverter from GX and switch it on for charging to resume without a GX. This guarantees industrial grade system stability. On a side note I just snuck in another 4 bricks to get to 48v 1000Ah/48Kwh energy stored - now the BMS is asking for 500A charge current at 52.8v and I have not the PV capacity to feed the beast ![]() ojeysky: 1 Like |

NiyiOmoIyunade: Actually noting spoils if the pi losses connection to the inverter though that hardly happens unless the pi is switched off, but in that case the last set float voltage is maintained. The pi does various other automation on my house gadgets as well but I make sure it's resource is not stressed. There is still the battery BMS in-between that keeps things in check. However, I certainly believe the victrons will expectedly perform better, let's just say this is my own way of maintaining certain level of performance at a fraction of cost. ![]() 1200Ah/48v LFP is something else o..... You've become a mini grid o. My 560AH/24v is already more than enough for my needs |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 12:46pm On Oct 15, 2020 |
earthrealm: bro, firstly, we all know that c rating (as regards battery capacity) is the safest maximum continuous discharge rate the battery will support. a carefully calibrated load is applied until the voltage gradually depletes to 1.75v/cell (lead acid) or 1.0v/cell (nicd/nimh) and 3.0v/cell (for li-ion} having said that, while i wouldn't want to pick holes in trojan's claims, i do understand that battery c ratings and capacity are not cast in stone. for instance take the case of two batteries with 200ah c10 and 200ah c20 respectively. the first battery with a capacity and rating of 200ah c10 may turn out to be actually 250ah when discharged at c20 depending on battery chemistry and quality of materials used to produce it while at c100 it could go higher to 320ah in capacity as an example. i do see most of our sellers here bandying all sorts of batteries for sale. they put out a lot of info but leave out the most relevant which is the c rating of the battery. i guess they are either ignorant themselves or perhaps they are feeding fat on the ignorance of potential customers. if i buy a c100 rated 200ah battery unknowingly thinking it is c20, i'm invariably buying a 170ah battery. no wonder many peeps here keep complaining of dead battery after just a few months of usage. 3 Likes |

When your base load is 3kw to 4kw overnight. 48v 1200Ah doesn't really go very far.... For your price vs performance tradeoff argument, I used to be a staunch advocate of value products e.g I used MustPower inverters for nearly 4 years. At some point my paradigm changed.

Re: Solar Energy, A Complement To FTA by Oshomo12(m): 6:06pm On Oct 15, 2020 |
NiyiOmoIyunade: I will love to see how well your array will perform with this new battery capacity. For me, I will stick with that 19kw array, to get value for money on the panels. I want to believe you have just matched the array with ur new capacity. Before, it was an underused array system. This is my take o. Further expansion of array might be a waste. |

eleojo23: yep bro. that isn't a typo. i meant exactly c100 as against c20. if it was a c10 being sold off as a c20 battery, of course the customer would be the one at an advantage. curiously, same trojan has a c100 battery with glowing capacity rating and non-savvy peeps might be tempted to rush it thinking it is a good bargain. not so at all. 1 Like |
Re: Solar Energy, A Complement To FTA by Trippledots(m): 8:32pm On Oct 15, 2020 |
ojeysky: Obvious to a keen eye oh. Take for instance, I couple 18650 cells to give a 12v battery and advertise the sum of the cell's Ahr capacity. That advertised Ahr is false with regards to the coupled battery's voltage. Do you get? It's mostly common with combo packs where they sell inverter and battery packs, or battery with DC-DC converters to charge devices and run some DC loads. I almost fell for it when I was shopping on AE for battery banks. |
